The transference of energy from point a (heat source) to point b (needed delivery place). There are 4 different ways of doing so.
1. Is with moving of tempered air through large ductwork.
2. Moving of a liquid through pipes to a energy defuser of said energy
3. Radiant heat; like a heating element heating an oven or a fireplace heating a room or the sun through a window heating up the room in the wintertime.
* Forced air: This is the cheapest way to install a heating system with the poorest way of heating the objects in the house. With some manual and electrical parts running the system. When the furnace fan turns on it blows cold air for a couple of minutes until the ductwork gets warm. Then it delivers the needed warm air for warming the ambient air in the room. Once the room temperature is reached, the air passively warms the items in the room. Starting with the ceiling and upper walls of the room working its way down to the floor.
* When it comes to cooling the forced air system works the best. I takes a powerful fan to drive the cold heavy air to the top floor allowing it to cascade downward cooling the item’s it come in contact with. This means the floor will be the first large surface to be cooled than slowly it works it’s way up to the level of the thermostat. You will still have a lot of hot and humid air at the ceiling if the heating contract did not install a high wall return air duct.
* It’s also the best and I think the only way to really clean the air, removing air born allergens out of the air. You can use secondary air filtration units but the biggest one I’ve seen only does 1 room at a time trapping a person with allergies in 1 room or in 1 area of a house. Using a high quality air filter on your furnace (they can be Paper) about 5” thick do a great job of cleaning all the air for the entire house.
* Hot water heat: Is a good way to heat a house. With a boiler you convert fuel into hot water. With this type of system you can do multi-tasking of different types of jobs at the same time.
* Such as using radiators to heat the air, in-floor heat to heat floor surfaces such as front & back entry floors to melt the snow and evaporate the water or heat the bathroom floor and even heat the sidewalls of your shower to make your shower a better experience for you.
* With in-floor heat you can heat the basement floor that is the hardest surface to heat, while using hot air blows above the floor it will never actually heat the concrete floor. But having the pipe in the floor, the floor becomes a large radiator heating the room, making the enjoyable, instead of saying well we have a basement. Whats so nice about in-floor heat you have no moving air or cold drafts moving across the floor.
* The next area to heat with the hot water is the garage floor your car will love it the snow and ice melt off of it quickly taking with it the salt. Using a forced air blower in a garage is nice but the floor all ways stay cold and if you in your garage a lot you differ projects on till the warmer months of the year.
* And finally you can heat your driveway and sidewalks, think about you newer have to lift a shovel again.
* Steam Heat: Steam heat is the most efficient way it has the greatest exchange of energy. The only draw back is you must have a licensed steam boiler operator in house 24/7.

All new houses in Minnesota are required to have radon removal system installed into each housing unit. Various designs are allowed by the state some with collection tanks (sump baskets) and some with out. The state haves mandated the following items that must be done.
Install a perpetrated drain pipe around the interior foundation wall with a minimum 4 inches of course fill not sand allowing water and radon gas to migrate to the collection center.
Install a continuous 6-mill poly vapor barrier under the entire concrete floor
Seal all penetrations coming through the concrete floor pipes block wall to floor edges etc…
Seal the collection tank only leaving 2 sealed pipes coming out 1 for removal of underground water; the 2nd is for the removal of radon gas.
Install a 3” vent pipe vertically from the collection area passing through the house and venting above the roofline.

Let’s look at the actual working of installation of said law, install a 6-mill poly on the dirt before you lay out rebar or wire mess. The steel being inserted onto the concrete keeps 1 the concrete floor from cracking, separating, shifting, or shrinking 2. It reinforces the floor incase the dirt under the floor settles. Rebar comes 1/2” x 20 feet long and is heave and flops around like a fish out of water. You will have a number of holes in the poly liner before the rebar is laid out and tied together. If you use wire mesh this comes in rolls of 5 foot wide x 20 inches diameter about 100 foot per roll, when you unroll this little monster it acts like a slinky wanting to recoil the only way to straighten it out is to flip it over and re-bending it by hand. Resolutes at each end of 1 row you have just punchered the poly membrane 10-12 time.
The code says you must take a new piece of poly and over lap the hole by 1’ on all sides no a basement of 22 x 38 (24’ x 40’ House) a minimum of 120 holes. Now its time to pour the concrete (concrete is a mix of sand small rock, portland and water) you can install it 2 ways; wheel barrow it to the location and dump it, or you can pump it in with a large pump truck add $800.00 to the bill. Did you fix all the holes the wheelbarrow made and the guys pouring the floor, well that’s a radon leak.
After the floor has harden up you walk around the floor sealing all joints between the floor and wall and floor and any protrusions through the floor. About 1 –2 years after the house is done because you chose not to install reinforcing in the floor your floor have at least 3 and up to 10 large cracks big enough to put a tooth pick in it. Oh that’s right you laid carpet on the floor you’ll never see the cracks where the radon is getting in the living space and where Johnny and Amber likes to play and sleep on the floor.
Let’s look at the collection and exhaust system. Remember in this collection area there is standing water as well as an electric pump to pump out the ground water. Facts undisputed radon gas is heavier than air. So radon gas builds up in the collection tank it never leaves the tank and the vent pipe because it’s to heavy now the ground water comes into the collection tank what happens to the radon gas it rises and falls according to water level in the collection tank. In fact the radon gas in the tank will increase in the parts per million making it more toxic I feel bad for the plumber that must change out the sump pump, he has to get down in there to fix the problem. Note when the radon gas moves up into the exhaust vent, it’s now looking for an easier way out, that crack in the floor has a lot less pressure and a bigger area to expand into. Solve the problem (the states view point) Just add a fan and blow the radon gas out of the house. The problem is it does matter how small or big the fan is if there is no air coming in to the drainage system you will never blow any air up the pipe, let alone radon gas which is heavier than air. The state say’s all you need is a small fan, may be rounding about 10 minutes per hour. 1st the state don’t have a clue how much air in cubic feet of air per minute or per hour is going to ventilate the radon gas from below the floor to solve the problem.
Let’s say it’s possible to vent this gas out of the house, well you don’t want to see the pipe from the front side of the house, let’s vent it on the back side of the roof, great or is it. On the backside of the house are the following screened, porch, deck, sand box, swing set, and other toys to play with. Radon gas is heavier than air it’s pumped on to your roof and taken away with prevailing winds and if there is no wind it rolls of the roof and into your backyard. Looking down at your house from the sky we see the following a pipe sticking out of the roof with no cover over it and you can not cover it by law, that means when it rains water goes down the pipe so what it goes into a sump tank if water can go down so can cold air in the winter time, when this happens it will freeze the surface water in the sump tank or the ground in the collection area and if there fan is installed water will be dripping and getting the fan soaking wet. Well we no longer can use a cheap fan we must put in a stainless steel fan with a concealed shaft with a water bypass system in it. ”$” Now to make this system work we must bring in air into the drainage system. We cannot take inside air just for the fact if the power went out the radon gas has an easy way back into the house. We can us outside air it 20 below or greater in the wintertime freezing the sub soil under your floor and leaving the opportunity to heave your footing.
The only air available to you is in the new law that no one has thought about, you must have an exhaust fan run 15-20 minutes per hour. Blow this air under you floor and the radon fan pumps the radon gas filled air out of your house. Now you are running 2 electric fans and praying the power never goes out.

Or Just excavate and other 24” lower and install an angled concrete slab 4” with rebar cover with epoxy paint than build on top of it for your house the radon gas will come in contact with the lower slab and slide upward to the surface level on what ever side you choose to bring it to the surface

We think we love them, they have been a part of the American dream since the days of the pilgrims. The lingering quest in homeownership how do we protect them from the elements, after that how to make them warmer years after they have been built.
In the old days the log houses used the logs as insulation and a barrier from the elements, the timbers in a log house were a good insulator because no air could pass through theses timbers, just around them, as the logs dried out naturally over time they shrank leaving gaps, while the body of these timbers have released the trapped water it now traps billons of air pockets pushing up its insulating ability also over time. In the late 1800-and early1900s people were packing their balloon-framed houses with newspaper thereby creating a low R-value in the exterior wall cavities. During WW11 to save energy they required houses to be insulated the houses using insulation that was batt of fibrous material about 1 1/2” thick placed into the stud cavities.
Today we have to tighten our budget again because of the high cost of living. One place to do this is to insulate our houses from the exterior than install new siding over the insulation, but there is a catch if done wrong it will rot your walls, what would take nature 60-80 years could be done in as little as 3-8 years. Houses built before 1950 were designed to breathe, it wasn’t until the last 10 years that we had no idea as to how much water vapor actually passed through the exterior walls of our houses. If our house has a crawl space, cement floor, basement foundation walls, that are now waterproofed on the inside (not water resistive paint) you could be absorbing anywhere from 10-150 gallons of water per 24 hour period into your homes atmosphere this water vapor wants out of your house because there is less humidity outside than there is in your home, thereby forcing its way through your exterior walls to the out side.
Now the Law states you must install a house wrap. House wraps work great in the far south, but what happens in the north is a world apart from the south. The inside temp of the house is 70° outside is 30° automatically the water vapor in the house wants out the humidity in the air outside is dryer than the air inside so it forces it’s way through the exterior walls. If your installer installed a house wrap under your siding this is what is happening the water vapor just past through the insulating and wall sheathing, the next surface is colder so now it freezes on the back side of the house warp (you have white frost between your wall sheathing and your house wrap). When the temperature warms up the frost now turns to a liquid, with tarpaper the paper sucks up the water and spreads it to help it dry out the back side of the siding. While if you installed a name brand house wrap it now pooling up behind your siding. It a liquid not a vapor so it is not allowed to pass through, but instead it starts freezing and thawing on your wall sheathing breaking it down.
Adding more insulation on the exterior of the wall if done right will save you a boatload of money. On the exterior of a building you best results are going to be from a rigid insulation board. There are at least 2 types 1st is just an insulation board and the 2nd has aluminam foil on both sides you must choose according to the siding you want to install as to what insulation board is best. For example; horizontal cedar lap siding does not like aluminum for behind it. Before installing any type of rigid insulation on to an exterior wall surface you must make a way for the water vapor to escape to the outside air.
I recommend 1 product “mortairvent” Made by Benjamin Obdyke, it’s only 1/4” thick installed over the tarpaper, than you install you insulation board next and finally your siding. It’s made of woven plastic with enough rigidity to keep 1/4 inch air gap to allow the water vapor to escape either by going down the wall to be vented at the foundation line or vented at the soffit line of the house.

Home ownership is a heavy responsibility for any person. But in times of economic hardship how does one manage to balance the budget and proper maintance of ones home. In the coming articles we will be addressing a slue of problems with work around situations.
Example: A tornado comes through your neighborhood leaving a lot of wind and hail damage. Your roof was damaged, you have good and bad news because of the act of nature, and hopefully you have insurance. Now the nightmare begins you contact your insurance company and they tell you to get 3 bids from contractors. You try to find 3 reputable contractors the prices are all over the board. Supper low a midrange and a high price bid. Now you have to decide which one you are going to submit to the insurance company. To do this you have a startling realization you have to learn how to roof your place before you can understand the jargon in the construction trades.
Now let’s get down to the nitty-gritty of roofing.
A. Protect the house from falling shingles.
B. Remove all shingles, tarpaper, and roofing nails/staples.
C. Check roof sheathing, it may need to be re-nailed or replaced.
D. Note roof boards are not a uniform surface therefore the shingle company will not warranty and type of shingle on this surface. You can cover the board with 1/2” plywood than you are better off. And a warranty.
E. Remove all the siding that sites on the roof, (Where a wall surface stops at the roof) about 2’ up from the roof.
F. You are required to install an ice and water barrier on the roof at least 2’ up the roof past the outside wall line. If you have a 2’ overhand on the house with a 4/12 pitch roof a minimum of 4’6” Ice shield is required. If you have a 12/12 pitch roof
a minimum of 5’2” ice shield is required.
G. I also run ice and water shield up the valleys and along all roof all edged where
flashing tins are used.
H. Install your valley tin next. Only use minimum expanding metals in the valleys never use aluminum any where on the roof.
I. After the metal valleys are installed, cut a piece of ice and water shield down the center install 1/2 of it on each side of the metal valley over lapping the metal by 3”. This is where most roofs start leaking; remember to start at the bottom when installing the ice and water shield.
J. Remember you get what you pay for I have use many brands of Ice and Water shield. The only one I now use and is the best is called “Grace” It bond to the roof decking but after many years it’s still pliable not brittle in other words it’s still sealing the roof decking from the water above.
K. Next cover the entire roof with tarpaper even the ice and water shield. Reminder ice and water shield will have water beading up on the topside of it. It’s a water barrier therefore you must remove the water from the underside of the shingle to do this install 1 layer of 15# tarpaper. This will wick the water out and allow the shingles to stay dry, making them last a lot longer.
L. Now you are ready to shingle the roof keep your lines straight both left and right as well as up and down. The shingle manufacture says to nail the shingles with 4 nails this will keep the shingle on the roof for winds up 60 miles and hour. If you use 6 nails per shingle you have greater holding power and can get a deduction on your insurance policy for a better job.
M. Going to a laminate shingle is much better than a 3 tab shingle because of how they are built and again some brands are a lot better than others I use Certainteed Land mark series with great results.
N. Make sure they don’t trash your yard, plants or bushes. Make sure they pick up all the nails; they will get all the debris.
With this information and reading your contract you should be able find a go contractor.

Construction Tips, Contracts, Materials, Roofing
1. Does the contractor have liability insurance? If something goes wrong who will cover your loss. I heard of a roofing problem in the summer of 08 they tore off the roof and installed a new roofing system. It looked good it didn’t leak, but when the roofers were tearing off the old roof they inadvertently unlocked the furnace flue pipe 8’ below the roofline. When the flue pipe was re-shingled into place the pipe was 1/2 on and 1/2 off the lower pipe venting carbon monoxide into chimney chase and ultimately into the house attic. They didn’t find the problem for 5 months, thank God no one died. When Natural gas or LP gas is burned it gives off carbon monoxide and a lot of water. The water leaves the furnace at about 350 degrees; at this temperature it’s steam being forced into a cold attic with a lot of cold surfaces. When the steam touches a cold surface it changes to water or ice. In this case about 2 inches of ice crystals on under side of the roof decking, on the trusses and on the surface of the attic insulation. A quick calculation looks like about 200 gallons of water frozen in the attic. Looking at this job after the facts all the insulation in the attic has to be removed the roof sheathing has to be checked for soundness and may have to be replaced as well as the sheetrock ceiling. You might need new flooring also if the ice melted before you removed it, because it will follow the wall stud cavities to the main floor and under your carpets, or cupping you hardwood flooring.
This is only 1 thing that can go wrong; there are many other situation I have heard about.
2. Does the contractor have worker compensation insurance?
If person falls or get hurt in any way while on your property (grass, sidewalk, inside your house, etc.) you’re at fault, unless the contractor has workers compensation insurance.
Rules for hiring a contractor:
General Information
1. Does the contractor have a state license to do the type of work needing to be done?
2. Does the contractor have liability insurance? If something goes wrong who will cover your loss.
3. Does the contractor have worker compensation insurance?
If a person falls or get hurt in any way while on your property (grass, sidewalk, inside your house, etc.) you’re at fault. Unless the contractor has workers comp. insurance.
4. Make Sure All Subcontractors and/or Any Person Coming Onto Your Property Has Legal Workers Compensation and Liability Insurance.
5. Does this person have the brains to pull off this type of job? Watch out there a lot of cons out there calling them contractors only wanting to separate you from your money.
6. Can he/she prove what is being said in writing; a contract that protects you the Homeowner?
7. A lot of people have go good intentions but no knowledge or life experience to draw from.
8. There are 3 classifications of quality of work
A. Poor and well below sub standard workmanship
B. Just Average on workmanship
C. Excellent work- any worker just above average ends up excelling to excellent static because of the person himself, I’ve seen this time and time again.
9. 2nd Classifications of motives.
A. Money is a good motivator
B. The lack of money is a poor motivation
C. Lack of time for said job or out of on contracts personal bills
D. The only job available this one, actually scores just above average
E. Actually caring for his work and the client.
Now is the contractor your hiring going to hire subcontractor with substandard work or money problems? Remember this your project is to be a work of art not a novel of science fiction.

On hard metal pipes the air moves swiftly through the pipes with little to no hindrance the pipe walls are smooth galvanized metal with adjustable elbows as needed. The minor drawback of this type of pipe is the metal you must hot or cool the pipe first before tempering the room that it’s being sent to. The good thing about this type of ductwork it never comes apart all the joints are screwed together and all seams are now sealed so no air leakage. Finally when its time to have your duct work cleaned, they guys bring in 2 hoses a large volume vacuum hose and a large volume air compressor hose with these hooked on ether end each duct the volume of air used to clean the pipe run handles is with no problem.
Now with insulated flex pipes the air moves swiftly through the pipes with little to no hindrance the pipe walls are made of a spiraling piece of wire in beaded in the poly tubes pipe wall than covered with insulation and a 2nd poly to keep the cavity air space that the pipe is passing through. Sorry to say the inexperienced installers use this ductwork a lot and in places that it was not intended to be used. Granted this pipe is very flexible but bending the pipe in a hard 90° or even 180° and/or squeezing it down to fit a 3.5 inch space cavity. When the inside pipe measures 6” and the out side measures 8 1/2. A 6” round duct has 28.26 Cubic inch of open area when you crush it down to 3 1/2” on the exterior; the interior only has 5 cubic inches of open area. The bad thing about this ductwork is if too much air pressure and vacuum is used in the pipe run and the connections come apart and contracts to the vacuum side of the cleaning.

When you need this type of ductwork cleaned, many things can go wrong 1 the joints can come apart. The compressor hose can puncture the inner poly wall of the pipe, or if there is a restriction in the pipe and there is debris in the pipe it could clog. Remember these entire ducts are running in concealed spaces between your ceiling and 2nd floor or your basement ceiling and your main floor. If they disconnect there is no way to re attach them with out remove 1 of your finished surfaces.

All kitchens should have exhaust fans, a lot of hood fans do not vent the bad air to the out side, but instead they push the air through a charcoal filter and than exhausted it back into the kitchen. When these hood fans are used over 50 hours of use the charcoal filters should be changed. If you don’t, are your doing is blowing the smoke and cooking smells into the rest of the house.
Using an exhaust fan below 300 Cubic feet per minute, most houses have areas that leak this much air into these houses. Newer homes leak about 150 cfm around windows and doors.
If an exhaust fan is turned on blowing out 300 cfm, your short 150 cfm and it will draw it from a bad source. One of the easiest places for the air to come into the house is by sucking the air out of the chimney either the fireplace or the furnace chimney.

We remodeled a house along with the kitchen; we installed a 1280 CFM exhaust fan. We told the homeowner that he need makeup air he refused Than came thanksgiving, the family was there the owner has a 5’ wide and 4 tall open wood fireplace the fire was going for about an hour when the wife turned on the kitchen fan. Instantly the fireplace chimney reversed bringing the smoke into the house the fire in the fireplace was still burning but the flames were blowing horizontally into the room. He wanted a quick fix so he had a 12” fresh air intake installed into the cold air return on his furnace. This did fix 1 problem the fireplace now works properly while the kitchen fan runs on full speed.
If the furnace is running it was not sided to handle super cold air coming into the heat exchanger. With this much cold air coming into the furnace, the furnace cannot heat the house because now it has to heat the incoming cold fresh air. The other problem is that the heat exchanger is being stressed with 400 ° on the burner side and -10° on the other side this shortens the life of the heat exchanger by years.
If the house is warm because of the fireplace the furnace won’t turn on. With the fresh air dumping in to the return air plenum, the super cold air is now coming out all the vents cooling down your floors making a draft along the floor to the fireplace and the kitchen stove.
The proper way is to bring fresh air into the house and run it through a furnace designed to temper the makeup air.

When your looking at types of ceiling finishes in the kitchen. There are things you must thing about.
1. Are you using your kitchen as a showcase? Be careful what you choice.
2. Are you cooking a lot with grease? If you cook with a lot of grease at high temperatures grease evaporates and bond to a cooler Surface IE the ceiling. 
Having a textured ceiling in the kitchen is a headache you cannot wash the ceiling. The only thing you can do is paint the ceiling and rolling paint on the texture comes off on the roller making a mess and to paint and clean up. Using a flat surface in the kitchen is an easy ceiling to maintain both in keeping it clean, or repainting the ceiling. If you are looking for a different type of look you can always use a knock down look not a easy to clean but very easy to repaint when you need to. 
In some architectural designs wood ceiling looks good if the wood is finished either with paint of varnish finish. Unfinished ceiling are bad because dust cobwebs and grease bonds to the unfinished and is hard to clean.
They make a steel panel ceiling. This is a great ceiling because you can clean this type of ceiling.
A cool looking ceiling is a glazed ceiling 3 or 4 tones of paint in the same color family with a clear coat covering it. Again this type of ceiling is easy to clean.

When designing a kitchen what should you be looking for when choosing a new window(s) in the kitchen?
There are 6 different types of windows available but only 5 can open. The picture window is just that a cased opening with a secured thermo pane glass installed in the opening.
Awning; With this type of window the operating devices are located at the bottom of the window that makes it easy to operate. These windows are hinged at the top and swing outward. The problem is that the kitchen countertop is 36” tall than the window is about 24-36” tall. IE the top of the window is between 5’to 6’ off the floor so when you are looking out the window at the sink all your eyes are looking at the top of the window jamb, you must duck to look out the window.
Glider; With this type of window the operating devices are located half way up the window that makes this window hard to operate when you lean over the sink and faucet.
Casement; This is a great type of window the operating devices are located at the bottom of the window that makes it easy to operate, also if the wind is coming from the left and you want to bring the air in open the right window and it will hook the wind and bring it into the kitchen.

Double Hung; This is a good looking window but it has a draw back you must on unlock the window, the lock is half way up the center of the window opening it from the bottom is adequate again the sink and faucet is the way.

Hopper; A hopper window is a cool design of a window but it swings and tilts into the room in the swing mode the window can not open the faucet is in the way.
Transom; Having a transom window over the regular kitchen window is great unless you have a ceiling under 9’ again the bottom of the transom and the top of the regular is in your line of sight.

6 major types of countertops; Laminate, Wood, Metal, Corion, Tile, and Stone tops.
Looking at these different types of tops, how are they going to perform for your needs?
1. Making bread or cookies the worst type of counter top is tile, it’s not the tile but the grout joints, the flour and doe get into the grout areas and you have to work hard to get it clean.
2. Cutting Vegetables, fruit on the counter; Laminates and Corion IE plastic base polymers not do go with cutting utensils will leave cut marks in surface. Metals will scratch, while wood will age and look more rustic looking, while stone and tile will dull the utensils.
3. Putting hot items on the countertop; Laminates will leave a blister mark where the hot item was set. Wood tops will leave a darker brown mark above 400° while as polymer base products will turn a different color again above 400°. Metals, and stone have no problem handling the heat. Tile above 800°depending on the finish on the tile, Metals above 1500° and Stone above 5000°
4. Spoiling of oil or juice; wood will sock up the fluid like a sponge, tile grout joints will stain, stone not sealed, will allow fluid to migrate through the stone to the underside of the countertop.

5. Cutting raw meat; the only one that is not good, are the polymer base products. A case study was done after a prolonged use study, bacteria was able to establish it’s self even with proper cleaning with dish soap. On the other hand wood counter tops had bacteria right from the get go, but after a period of time the wood built up a resistance to bacteria and was more health for you.
6. Clean up; For a Kosher kitchen I recommend stainless steel you can scrub them, they can take a lot of heat, they a durable and will last a lifetime.

We had the privilege to watch a Mexican siding crew side and install 5 new windows into a split-level house right across the street from our job; they had 11 men the first day 9 the 2nd day.
One of the dumbest things we saw was a man hung over the gable end of the garage to remove the fascia, soffit, and as much siding as he could reach he was not tie off at all.
Another thing we saw was a man removing siding with an extension ladder as though the ladder was a crew bar, just under the man on the roof.
If either of the 2 men would got hurt, would they have insurance to take care of the medical bills or would they sue the owner of the property. Granted the general contractor had insurance, but did he or the homeowner check to see if the subcontractor had workers comp. Or even liability insurance. If something happened the homeowner is responsible not the contractor.
Ohsa law requires safety first.
1.Some of the law that were violated were working below an other worker you must wear a hard hat (safety helmet)
2. About 8’ off the ground you must be wearing fall protection.
3. Scaffolding must have a walkway not less than 19” wide they were using 12” planks
4. It is illegal to use the step ladders as they did, you must open the ladder up and make sure all four feet are secure before standing on it also you are not allowed to stand on the top platform this is not a step.
They had about 200-220 hours on siding and replacing the windows on a house that had 3000. Square foot of siding or 1100 SF split entry house. It was impressive to watch but looking back at the man hours I was horrified to see so many hours we had on 43 hours for siding 1/2 the house across the street and 1 sliding door replacement. We were working on a 1200 SF hour and replaced 30’ of gutters in this time frame. While the Mexicans are sending out another crew to put the gutters on after the house is sided. Looking back what a lot of wasted time they could have done the whole job in 2 days with 5 guys.

Where do I go for a new kitchen? Remember this 9tenths of the kitchen stores have no clue who you are or how you live or your unique physical abilities you have. They are there to get a fast sale and they’re on to the next customer. And you’re stuck with this kitchen for the 10-20 years. A high-end builder and /or remodeler should ask you these questions. To custom fit your kitchen to you and not having you do contortions in your kitchen went it’s time to cook something.
1. Who does the cooking? Who does the cleanup?
2. How is your eye sight? If your eye sight is poor you may need more lighting in the kitchen.
3. Is the cleanup person left or right handed? The placement of the dishwasher is vital for ease of loading and unloading dishes.
4. At what height do you like to work at tabletop height (30”) or counter top height (36”) workbench height (42”) or a height in between? Having improper work surface height is bad on your back, hips and legs. You may have a new kitchen, but hate to go into the kitchen not really knowing why.
5. What size is the family are you cooking for? This tells me what size the refrigerator has to be for breakfast. This also tells me what size cook top you will need.
6. How many different types of parties per year? Do you need a 2nd refrigerator for short-term storage? They make great under the counter refrigerators and freezer with pull out draws.
7. How much cooking do you do everyday? Every meal, or is there a lot of prepared foods, or do you eat out a lot? This tells me what volume of dishes you will be keep in the kitchen. IE if you cook a lot you will be baking cakes, pies and fancy items. This mean you will need a lot of preporation storage of mixer, food processor, etc., in easy reach of your work surface.
8. Now let’s look at your house and see the architecture of the home so we can match the
kitchen to the house. IE never put a modern kitchen in a house designed as an Amish or 1900’s bungalow home.
9. Are you going to feed the family in the kitchen or at a different area? If in the kitchen where?
10. How much square footage are you going to give to the kitchen area? If you need more can you take a little from another room or can we add on an addition.

It’s a great idea, heating your garage with a Reznor unit heater it shall do a lot of good things for your garage and items stored in it. By keeping the heat above 38° it will keep the garage foundation from heaving in the cold winter months. Also if the garage is attached to the house, the house benefits by heating the garage the common wall is now warm for the house interns saving you heat on said house wall.
Having it warmer also helps your vehicles start faster as well as better engine oil viscosity, because the engine block is starting warm.

Using a compact ceiling gas heater works great. We have installed several of these units. You can bolt them to the roof framing members and or floor joist system. You can mount them up tight or drop them down to a lower height if you have a 9’- 14’ high garage ceiling. By installing the unit at the back of the garage and blow air cross the garage to the far front corner this will get the greatest way to stabilize the temperature in the garage. This will also dry your car off and the floor. By keeping your garage temperature at or above 38° you should never have the garage floor flaking or popping of concrete from the winter weather.
This furnace also can be vented both out the wall and/or through the roof of the garage. Giving is a way to really maximize your opportunity for the best installation.

3 types of solar collectors.
The vacuum tube type works great. It can reach temperatures above 350° and becomes a good collector. The down side of it is when the snow and/or frost lands on the vacuum tube collector the sun has to warm it up to evaporate the frost, and with heavy snow you will have to clean it off the solar panels manually. If you remember to clean the panel if not this will loss you hours of solar collecting.

2 types of Solar thermo panels
Home made solar collectors have a couple of problems: They are not sealed and filled with inert gas (argon gas) there by missing a key way of collecting solar heat. Improper way of winding the tubing inside the panel is another problem.
Flat panels commercially made are a great way to collect heat. You can set the collectors on most any type of roofing system. They also can be joined together for a greater Btu output. The maximum output will yield you any where between 50-70% of your domestic hot water. Having extra cash to go green is great but if you need this to be your main heating unit for hot water or limited location for hot water storage, this is not the system for you at this time I’ll check these systems out every couple of years for better results.

Boilers, furnaces and water heaters – figured for a 2000 SF house
For boilers
Water – minimum operating pressure 8 LBS per floor. A 2 story with basement –requires 24 Lbs operating pressure.
Cleaning cycle for the burners at least every 2 years
Fuel – Natural Gas, Propane
When gas is burnt it’s by product is water and Carbon Dioxide add this to a steel heat exchanger this creates rust. When rust flacks off the exchanger it falls on to the burners below creating bad combustion an lose of efficiency.
Oil #2 a Oil burners are a unique creation they blow fuel oil out at 100 PSI This oil is ignited by 2 electrodes at 10,000 volts. If/or when the electrodes burn back, and /or twist it will soot up the heat exchanger and flue again loosing efficiency.
Heat exchangers over time loss there integrity from the heating 350° 72 times in one cold winter day. When the exchanger breaks, cracks- carbon monoxide is now being pushed in to the house.
When you move air for heating and cooling you must clean or change your, also check to make sure your furnace fan blades are clean. If not use a screwdriver and clean each fin. Just have more air moving through the furnace will increase your heating and cooling efficiency.
Systems check –
Proper start up of burner -does it start with a bang or take a long time to light
Make sure the high limit control shoots down properly at the right temp.
Check for proper airflow out of the blower check the fins on the blower fan for lint buildup.
Cost of a new heating and cooling system with ductwork – $ 15,000.00
Cost of a new Geo system with ductwork – $ 24,000.00 with a well system
Cost of a new Geo system with ductwork – $ 18-20,000.00 with a in ground loop system
Cost of replacement of a furnace & AC system. $8,500.00
Cost of replacement of a Geo system $6,500.00

Everything always comes down to money how much is it going to cost me. Granted houses are not our greatest assets actually it leans more into the liability side of the spreadsheet. With this in mind how can we convert a liability into an asset or at lest break out even.
1. Location is the first biggest hurdle to overcome. Were to build or buy a house (neighbor hood) these three locations are about 4 miles apart
– examples-
a. Poor location -a house located in St. Paul Park next to the oil
refinery has a lower value therefore a lower return on your investment
b. Average location- a house in South St. Paul most of the homes are small square footage.
c. Good location- South Maplewood next to the St Paul sky jump In this location the lot values are higher so is the return on your investment.
2. What Type of house is the best type of investment to buy either 1story or 2 story with a full basement at least an 8” high basement ceiling. Don’t buy a split level their hard to dress up, or add on to the structure. It is nice to have a walk out basement but not necessary.
3. These are some of the things we should look for in a house.
Basement
Drain tile under the floor of the basement and out side the foundation
A flooring system to carry an adequate working load of your living style
Is it good to know what type insulation? fiberglass, foam if its cellulose it’s not that good.
Exterior weather protection – what type- wall? Brick, Wood, Steel, Aluminum, Vinyl
– Roofing? Shakes, Shingles, Steel, Hot tar roofing, rubber
Floor coverings? Stone, tile, wood, vinyl or carpet.
Appliances (furnace, water heater, water softener, humidifier)
Don’t look at the poor paint job, out dated appliances, or the bad carpet these things can be replaced.
4. What is the life cycle of the Roofing, siding, windows, and driveway
5. Do you own these items or are they going to own you (Time and Money)
6. The main thing you look at is floor pattern can you live with the layout of the house.
When these questions are answered with no emotions than you have the right to look a little deeper into the property. Call the city and/or county and ask for info about the property. Never address the property as your house or the house until you actually own the place. This way you will keep an open mind if a problem crops up. You leave the property with no regrets or hurt feelings.

Insurance agents sell you on the fact that when you sign up with an insurance company you will have full coverage minus the deductible. You set the deductible amount than this sets the payment schedule. In Minnesota if you have hail damage on the roof and/or siding the insurance company only has to replace the damaged sides of the roofing, and siding on the sides that were damaged. Even if the color does not match from old to new roofing and siding, this is the Minnesota law. Another clever word the insurance companies use is “depredation” they use this word in a cleaver way to avoid payment of funds. Example a house was build 15 years ago with a 25-year shingle they say 3/5’s of the shingle life is gone. The insurance company call it depreciation the roofing job costs $3,000.00 x deprecation (3/5) = $1,200.00 minus the deductible is the check they give you. Yet the coverage you bought for insurance was full replacement value. What they have done is swatted the phrase (% of funds until completion) with the word (deprecation). When the roof is completed, and you force them, then they will pay the balance of the deprecated funds being held, But not the bill incurred by the homeowner. What do you mean? The actual bill for a new roof costs $11,000.00
Yet when you have to have your roof torn off and reshingled because of hail. The insurance companies don’t play fair. The insurance company gives you enough money for the homeowners to reshingle and side the buy themselves with no contractor help. The money you got from the company is enough to pay for the permit and supplies only.
Have fun. .
Minnesota requires that the building contractor must be licensed to work in Minnesota. To get a license you must have 7.5 hours of schooling a year.
Liability insurance must be above 300,000.00, and Workmen’s comp. Insurance.
The contractor has a lot of overhead that must be spread over the 250 working days for the year.
![]()

Yet with construction there are always rough weeks were we have to work 60-80 hours and other weeks there is no work. On the average we work 35 hours a week because of this the office overhead has a shortfall of funds Taking money out of the owners pocket lowering his wages.
With the way the insurance companies are paying out funds to get theses houses fixed. Good contractors will not fix insurance claim houses, leaving the door open for poor quality and scam artist contractors willing to do these jobs. Hugo city hall is very upset about the poor quality of contractors working in their city. They can’t figure out how to get a better caliber contractor to do these jobs.

Let’s look at the first electrical panel. There are 3 problems with this panel. #1 The 2 high voltage lines and the neutral line coming into the the main shot off switch are painted white. These is not legal, The 2 high voltage lines required to be marked in black and the neutral must be marked in white. This is not only a state code but a national code.
![]()

#2 If a person needed to add and outlet on an existing circuit and opened up and an existing outlet box cover and saw the white wire he would automatically think black with black wire, the white with white wire and ground, with ground wire. 98% of the time you would be right, but if the white wire is not labeled properly in the panel as a 220-volt, at the same time the outlet box is also improperly labeled you would cross wiring a 110-volt appliance with 220-volts and burn it out that is if it doesn’t start a electrical fire.
The 3rd problem is this panel is a 2nddairy sub panel. When you wire a sub panel the neutral wire must go to the neutral bar and the ground wires must go to the grounding bar. They cannot be mixed it the law.

On this next photo this electrical panel was done properly. The high voltage lines are labeled properly as well as the 220-volt circuits and the neutrals and grounds are supported properly.

The question is; Can the stairway hold it’s own weight as well as the working load being put on it.
Osha requirements for a stairway;
From a design standpoint, the specified design loads (e.g., normal live load and moving concentrated load of 1000 lbs.) must be placed where the maximum stress is experienced by the individual structural components of the stair system.
![]()

Looking at a framing section of a stairway the sawtooth cut boards are called stair jacks. Looking closer at a jack the deepest cut of the notch for the step into the jack to the bottom side of a jack if your using a 2” x 12” will be 3 1/2” to 4” of uncut material is equal to a 2” x 4” with this understanding we can calculate out what a 2” x 12” stair jack system can carry. With all lumber we do not measure the length of the steps from the top to the bottom but instead from the front edge of the step to the load bearing point that supports the top of the step. A wall height of 8’ and a floor joist of 9 1/2” will make the run of the stairjack 12’5”.
![]()

A single 2”x 4” spanning 10’2” can only carry 10 Lbs. per running foot times 3 jacks a total of 300 Lbs. Nailing a 2×4 on the side of the jack doubles the working load to 600 Lbs. But on the problem above we are short 2 1/2 feet. Going to a 2” x 14” stairjack will leave a 2” x 6” amount of material left this will carry a 20 Lbs. 12’9”
With 3 Jacks the total dead and live load for this stairway is now 12.75 x 20 x 3 jacks= 765Lbs. adding 3- 2” x 6” on one side of the Jack doubles the load 1530 Lbs. This is now a legal working stairway for wood steps.
The problem now comes in when the homeowners want stone on the treads and risers. The weight alone is 32 Lbs. per SF or 1153.1 Lbs. for this stairway. And it only leaves 377 Lbs. for live load. Changing and using a LVL or a micro laminated beam works much better. Using a 1 3/4” x 14” LVL beam with a 12’9” span will carry 68 per SF. X 3 Jack you a total working load of 2601 Lbs. this passes with flying colors. This gives you a live load of 1448 Lbs. Or in other words, you can have 6 adults sitting or standing on the stairway for a group photo and it will not wince.

Installing architectural elements IE columns are a way to bestow grandeur, or an air of formality, reverence, and ha for ones surroundings. If your looking for a quiet place to read, or review documents having columns quiets the room down. When people enter they become respectful of the area. Installing columns in a formal dining room is saying to the guests that bar room manners are not welcome, and this is not a picnic ground, so put on your good behavior.
![]()

If your looking for a light hearted atmosphere to dine with children this is not the room for columns.
![]()

Columns make a person take note of their surroundings that something has in the past, present, and/or near future will be happening in this place.
Going back to theses homes I have installed these columns, It bring me back to the meeting that I had attended in these rooms over the years.
Installing cheap columns or ones that are improperly built cheapens the room, which sends a massage to the people coming in seeing them actually ignore the fact columns are there, even thought they have to step around them as they walk through the house.

Oil fired heating plant (furnace or boiler system) needs maintenance by a good oil burners service man. There are a lot of service men but only 1 out of 10 Service men are really any good, and of these 1/2 of theses guys are great. With a good burner system and a great service man these heating plants will run great for years. An inexperienced service man will miss the tell tail signs the heating plant needs help. The picture below could tell a heating man what is happening before he even gets to the heating plant.
![]()

The picture you are looking at is not mold but instead it’s dirt. In this photo this house has hot water heat. There is no air filtration system in this house, as small dirt particles migrate into the wall mounted radiator (baseboard heat) heats the air as it passes by but the dirt is charged with static electricity than the particles are carried up the wall with the warm air. This is where the charged particle bond cooler parts of the wall. The framing of the house keeps the sheetrock cooler directly in front of the studs in the winter and warmer in the summer. This also happens with electric baseboard heat. Using an air purifier such as a Honeywell 17000 HEPA Quietcare Air Cleaner works great removing all the particulate in the air.

Mold comes in to the house in many ways. Always when there is water present.
1. Exterior water – infiltration (through the siding or the roofing)
Improper installation of the siding – no building paper or a house wrap was installed. Roofing again improper installation of roofing and flashing allowing the rainwater into the building shell.
2. Exterior water – under ground.
High level of ground water is big problem pushing hydrostatic pressure against the foundation wall, forcing the water into the foundation. The causes of high level of water are over watering the garden next to the foundation, rainwater coming off the roof then runs to the foundation. Following the wall downward adding to the ground water. Basement floors that have pour, or not properly installed drainage system can have 50 gallons of water evaporating in a 1000 SF basement per day
![]()

3. Interior water – leaking pipes and/or sweating pipes
4. 4. Interior water- high humidity comes from cooking, showers, people them selves sweat and put a lot water into the air.
When humidity levels go above 65% mold has the ability to start growing. The higher the humidity above 65% with temps above 68°, the quicker the mold responses to it environment. Lets look at a Refrorator very high humidity but low temps the mold is held in check because of the low temperature.
This time lets look at the cabinet under the sink there is a leak about a drop per minute.
The temp in the house is 70° and the humidity is 45%. But in the cabinet the temp is 68° and the humidity is 80% or better. The house air has no way to dry out the cabinet allowing it reduce the humidity, therefore in about 1 week mold will start to grow. In one year the entry interior sink base cabinet will be covered in mold. Now lets apply this to a stud cavity, humidity get trapped between the exterior wall sheathing and the interior sheetrock or finished surface. But this time you have no idea it’s happening and no way to check on the condition of the framing. Using a porous type of insulation in your stud spaces on the exterior walls is like begging for mold to inhabit you home on all sides of you.

I was approached by another contractor asking me to give them a price on larger home in Minnesota. They wanted a ballpark price in 1 1/2 hours. They had worked weeks on the biding of this house and were still edgy about the final price. From what they showed me 2 different sets prints that were designed by an architect. The plans were poorly drawn as well as the traffic flow and design aspect of the print. In the details of the prints there is to be a cross elevation of different location of house to understand how the house is to be built. These pages were missing about 80% of the information. Leaving it up to the lumberyard as to the design of the building. Or in other words the architect drew a nice picture. The builder has to draw his own conclusions with no supporting data has to loads and wind resistance of the building. Back to the contractor, he has hundreds of sheets of papers from a bunch of sub contractors, with prices all over the board for the same job to being done. The lumberyard alone has had the print of the house for a month, and final estimate of the lumber bid is still a lure. Information from the contractor to the sub’s was sketchy at best. The contractor had photo’s of ideas what the owner’s wanted but wasn’t following the design of the photo’s. This whole project is doomed for hurt feelings as well as the contractor will leave the job with a bad reputation.

The elements written about below are used in all modern house drinking water delivery systems.
These quotes can from different EPA web sites. A little disturbing I called a number of officials this late week to talk about copper drinking water supplies. What I found out was they were more concerned about the brass in the drinking water than the copper piping it’s self.
The 1st element is copper, and then 2nd element of brass is zinc. The amount of zinc varies between 5% and 40% by weight depending on the types of brass required.
EPA
“The 1991 rule aims to minimize lead and copper in drinking water by reducing water corrosivity. Lead and copper enter drinking water primarily through plumbing materials. Exposure to lead and copper may cause health problems ranging from stomach distress to brain damage.”
“Everyone must absorb small amounts of copper every day because copper is essential for good health. High levels of copper can be harmful. “Breathing high levels of copper can cause irritation of your nose and throat. Ingesting high levels of copper can cause nausea, vomiting, and diarrhea. Very-high doses of copper can cause damage to your liver and kidneys, and can even cause death.”
“A wide range of clinical symptoms have been associated with zinc deficiency in humans (Abernathy et al., 1993; Prasad, 1993; Sandstead, 1994; Walsh et al., 1994). The clinical manifestations of severe zinc deficiency, seen in individuals with an inborn error of zinc absorption or in patients receiving total parenteral nutrition with inadequate levels of zinc, include bullous pustular dermatitis, diarrhea, alopecia, mental disturbances, and impaired cell-mediated immunity resulting in intercurrent infections. Symptoms associated with moderate zinc deficiency include growth retardation, male hypogonadism, skin changes, poor appetite, mental lethargy, abnormal dark adaptation, and delayed wound healing. Neurosensory changes, impaired neuropsychological functions, oligospermia, decreased serum testosterone, hyperammonemia, and impaired immune function (alterations in T-cell subpopulations, decreased natural killer cell activity) have been observed in individuals with mild or marginal zinc deficiency.”
“Lead does not noticeably alter the taste, color or smell of water. The effects of low levels of lead toxicity in humans may not be obvious. There may be no symptoms present or symptoms may be mistaken as other illnesses. The only way to know the concentration of lead in water is through sampling and laboratory testing which is described in greater detail in a subsequent section.”

My heating contract was called into a house that was about 8 years old. The homeowner had a unique problem. In the master bedroom was located on the 2nd floor the toilet bowl was frozen and the bathroom temperature was 70°. The contractor though at first this was a joke. The owner insisted that he wanted the problem fixed. With a little bit of looking around the contractor saw the bath fan right above the toilet bowl. But the real problem was in the attic the exhaust vent from the exhaust fan was not insulated. With the out side temperature of –20F below. What happened the air inside the exhaust pipe being cold (and cold air is heaver than warm air) dropped from the ceiling fan and fell into the toilet because the husband left the toilet lid up the night before, Allowing the cold air to collect in the toilet bowl and actually freeze the water.
Another job site the homeowner had a new roof put on 6 months earlier and had the attic reinsulated. The first cold morning about –15 below 0 with a hot shower the ceiling fan started dripping water. So he called out the roofer to fix the problem, it was not the roofing but instead the exhaust fan piping again was not insulated. While the high humidity was being blown out and the metal piping was below 0 the humidity was condensing rapidly on the piping, then run back into the ceiling fan, through the vent louvers and end up dripping to the floor.
You have to insulate the entire exhaust vent to the exhaust point.

New houses need fresh air
The answer will move to action. A person will breathe in and vent per breathe 1/2 liter in quiet breathing to 6 liters or 1.58 gallons per minute.
Each person takes between 4 and 10 million breaths per year. The max volume of air that we take in and breathe out is called vital capacity. It’s about 4800 ml or about 5,000,000 gallons of air.
Each day, a person takes between 11 thousand to 28 thousand breaths per day per person or in other words about 13,698.6 gallons.
Calculates to 1,831.23 cubic feet per person must come into the house per day.
With this understanding, by tightening up our houses we need to bring in fresh air or we are going to poison our selves with our own exhaust air (CO2).
Installing an air exchanger into a new home is not an extra item that the state is forcing on us to do, but instead it is for our protection.
Having the Air Exchanger running 1 minute per hour per person in the house plus running it to remove humidity in the bathrooms while showers or hot tubs are running help stabilize the humidity in the entire house.

To make a deck look and function well there must be some planning done before you start building.
Location of the deck is very important.
Are you trying to use this deck for multi purpose or a single event place?
Example: Do the kids play in the back yard and you use the deck as an outpost watching the kids?
Or do you sun bath on the deck and need a little more privacy?
Do you like or hate the summer heat?
Is the deck next to the driveway, and all your friends migrate to the deck. Or is it a private getaway four the 2 of you.
After answering these questions you will see an Idea immerges as to the kind of deck you are looking for.
An other example; If your a party animal your going to want to barbeque on the deck with extra seating as well as a lot of accent lighting around the deck to call the bugs away from the guest with see through rails to the other parts of the yard. Installing steps or a stairway to get to the lower yard helps cut down on traffic thought the house.
Where if it is just for the 2 of you your going to want it a little smaller size deck with romantic accent lights and no steps to the ground and may be a more defused viewing area though the railing system.

Framing material and sizing has changed for tall walls, theses changes in Minnesota law is for the better.
Load bearing walls exceeding the 9′ height fall under a new law. The higher the wall, the better quality the wall this may mean thicker the studs.
Included in this new law you no longer can use Utility grade, Standard grade, No.#3 grade or Stud grade lumber of any species are not permitted. The change in law is because of wind resistance against the exterior tall walls.
Using a better species of wood than SPF (Spruce, Pine, Fir) will make a stiffer wall. SPF is the cheapest wood species that you can buy.
Classification of common grade lumber. Common grade boards generally contain more knots than the select grade. Common grade is divided numerically from 1 to 5 with 1 being the best in appearance. No. 3 and No. 4 common grades are most frequently used for such applications as sheathing or sub-flooring.
Lumber grade numerical system changes title when it is shipped to large discount stores. Having changed to names the consumer has know idea what he or she is buying. Changing the name the discount stores are able to sell more product to unsuspecting customers.
Economy is the lowest grade available. This is usually junk wood, damaged material taken off of railcars. You can get a lot of twist, wane, and huge loose knots with economy grade lumber.
Utility is the next grade up in quality from economy. The discerning consumer can usually find a few useful pieces of lumber at this grade. One of the functions in large commercial lumberyards is buying utility grade lumber in bulk and upgrading it to ‘stud’
Stud grade, as implied by the name, is the most common grade used to build the framework of houses. Thus, the electronic device used to find lumber under drywall in a house is called a stud finder. Since the primary purpose of stud grade lumber is to hold up a house, very little twist is allowed, although you can have large amounts of wane and large knots.
Standard and better grade is similar to stud grade. The difference between the two is not so much in the size of the knots or the amount of splits or wane allowed, but in the fact that standard and better grade is used for lumber that is 12 feet and longer while the stud grade is used for 10 feet and 8 feet pieces in grading.
No.2 and Better grade. This grade usually allows for smaller-sized knots and a minimum of wane and splits.
An even finer quality of wood is 1 and better. This is the crème de crème of lumber and should consist of small, sound and tight knots, only inches of splits, and practically zero wane.
Above 1 and better is select grade lumber. This is an even higher quality than 1 and can be used for high-end decorative purposes. Examples of this would be western red cedar, spruce shiplap, and tongue & groove wall paneling. Having mentioned that as an example, great effects can be had using lower quality cedar as paneling, incorporating its defects to achieve a western, weathered look.

There are a lot of basement foundation walls failing. Presently a whole lot of poor quality fixes. Some of which take up a lot of square footage of your basement to hold up the foundation wall, but don’t address all the problems.
These foundation walls were built good but they were not designed for your soil type and/or hydrostatic pressure of your lot.
In the 2nd picture it shows that wall is buckling inward, with a closer look a the picture we see 3 problems.
1. The ground is almost level with the top of block wall. This creates other problems that we will talk about on another post.
2. The yard next to the house is flat- when it rains where will the run off go?
If the soil you have is poor or unsatifactory; silty clays, organics, or peat,etc. these types of soil make great lakes, they don’t drain, they pond. Because there is no place for the rain water to go then it seeks the next available spot -loose soil. This type of soil has a lot of voids or air pockets. Every house that has frost footings and /or a basement has loose soil from 2′ and up to 8′ away from the house. The rain water runs into the soft soil and around the foundation of building. This inturn compounds the problem pushing hydrostatic pressure on the foundation walls.
3. Remember the wall has a horizontal crack it now lets water into the house

1. Remove the dirt next to the house
2. Push the block wall straight
3. Install 3/4″ Rebar in block and fill the block with concrete
4. Install a drain tile system
5. Water proof the wall with Black dog Waterproofing system
6. Put a Geo grid system to keep the dirt from mixing into the rock
7. Install any size rock from 3/8″ up 1 1/2″.

Box cabinets come in widths of 3 inch increments (12″, 15″, 18″, 21, 24, etc.) this means if your cabinet length is 5’ 2 1/2” you will need a 2 1/2” filler section on the facing of your cabinets. Custom cabinets are custom fit with no filler sections and more useable storage.
With box cabinets you have face frame of 1 1/2” wide per box, when you join 2 boxes together it becomes 3” wide with a vertical seam between all the boxes. Custom cabinets have face frame of 1 1/2” –2” wide allowing more room for access as well as wider drawers.
Most box cabinets have a 1/8”-1/4” overhang on the face from the cabinet box. This makes it hard to put crown molding around the top of the cabinet, as well as toe shoe around the base cabinet. These box cabinets have no extra material to custom fit the boxes to the wall. There will be a gap between the back wall and the cabinet. If the person installing the cabinet followed the bow of the wall now the front face of the cabinets are no longer straight. Installing a counter top on these boxes will have to custom made to get a big enough overhang on the counter top to make it look good. If there is a bow in the wall this could be hidden with custom cabinets.
The only time a box cabinet looks above average is when it has a full over lay door covering most of the face frame.
All the quality in box cabinets is located in the appearance of the cabinet, not in the operation, structure, or functionality.

This type of material is a one-way door system. It allows humidity in the stud cavity to migrate out to the exterior air when the humidity level is lower than the relative humidity in the stud cavity. Great concept. In actuality it has some drawbacks;
First you must make sure that wall sheathing is working with you on removing the humidity.
1. Using the house wrap only works when the humidity level is below 17% this is the level the framing (wood and sheathing) has to remain at to keep its structural stability. At higher levels of humidity in the stud cavity on exterior walls with cool evening temperatures, condensation forms on the exterior wall sheathing, runs downward to the sill plate and starts the decaying process. If the wall sheathing is porous enough to allow the humidity to pass through, and with drop in outside temperature the humidity will condensate or freeze on the back of the house wrap.
2. When moisture level exceeds 18% in the lumber and the temperature is above 40° fungi begin to inhabit the wood.
3. Where water is present bacteria can grow, when the bacteria reacts with the nails rust forms. Nails holding the framing together start to rust, more the bacteria the faster the stability of the structure is affected.
In my personal opinion House wraps causes more problems than they solve.

Building contractor(s) verses handyman(s)
What’s the difference?
The Department of Labor and Industry requires licenses for residential building contractors, remodelers, roofers and manufactured home installers. The department requires certain standards of education and professional conduct be maintained to obtain and retain a license.
Licenses are required for all residential building contractors and residential remodelers who contract with a homeowner to construct or improve dwellings by offering more than one special skill. Owners working on their own property must also be licensed if they build or remodel for the sole purpose of speculation or resale.
Liability insurance with limits of at least $300,000 per occurrence, which must include at least $10,000 property damage coverage.
Minnesota workers’ compensation insurance certificate or a written explanation of why the applicant is exempt from workers’ compensation requirements. Applicants who have no employees and have no intention of hiring employees (other than spouse, parent or child) during the next year should attach a written statement with the license application explaining the specific reason they are exempt. If applicant is uncertain whether workers’ compensation insurance is required for your business, contact the Minnesota Department of Labor and Industry at (651) 284-5005.
A handy man needs none of the above unless he and/or she does more than one of these items concrete, frame, side, sheetrock, trim, tile, hardwood flooring, carpeting, painting
If a handy man gets injured at your house he or his insurance company can sue the home owner. Always Protect Yourself.

A standard closet has one of the following types of doors; bi-fold, sliding, or standard door(s). These doors make it hard to get into the closets as well as being in the way of storing items. Doors also inhibit the movement around the doors.
This closet was designed for more internal storage, but it uses up 18 square foot of floor in front of the closet that cannot be used for storage and or any thing else.

Installing Lockers in the same place where you would put a closet, it will hold more items as well as being able to organize your items or your kids.
A walk-in closet laid out right yields more and better quality storage as seen in the next 3 pictures.

The owner wanted to put an addition between the house and the garage. The space between the house and the garage was 26′4″, City hall said we had to stay 1′ away from the garage with the addition.

The foundation wall and the framing walls was set at 12″ apart. Adding the siding to both the garage and the addition walls, the space between is now 9″.

The house’s foundation was down 7′, while the garage only had a floating slab. To get the foundation in, we had to dig down 7′ and remove the soil. The soil we were digging in was sand. Digging this close to the garage the sand under garage will slide out fast and up 7′ away from the garage under mining the garage, then the garage floor will break, this will bring the broken slab and some of the garage wall framing into the excavated hole. to solve this problem we built a shear wall to hold sand from shifting and sliding, keeping the garage safe.

The house was built in 1950 on a nice lake. The new owners decided to remodel it before moving in. We updated the whole house from electrical,plumbing, heating, phone, security and millwork.

We make our own pillars to fit each house. Buying factory pillars the heights are wrong for the jobs as well as are the fluting. factory flutes are done with a tables saw blade instead of a router giving a shallow look (cheap look).

On this photo we are building up the bases of the pillars.

Applying crown and bed moldings to make up a 6 ply cornice look.

House was built in 97 with a poor kitchen design.
Note the locating of the pantry at the far end of the room with a depth of only 12″.


We changed the location of the sliding glass door and the kitchen sink window. Then we flipped the kitchen layout to flow better with more storage.
There was a large footprint for the kitchen but no storage or ease of operation. People visiting had to pass through the cooking area to get to the dining table.

To the right of the kitchen sink is the dishwasher with a wood door panel to match the cabinets.

The center island has a built in microwave on the right around the corner on the right there is a built in bookcase. The center door has a 3′ drawer that hold 3 -13 gallon garbage cans with 2 recycling bins left the kitchen sink for glass and metals.
The kitchen, and bar sink are cast iron w/ a gray porcelain finish. We also installed a secondary Reverse osmosis water system to the refrigerator, kitchen, and bar sinks for better taste, as well as no impurity in the water.
When making meals in this kitchen, everything is ease to get to with plenty of storage for food, supplies, as well as decorations for any type of family get together. The layout of the kitchen makes it ease to be involved with family whether there in the family room or in the kitchen.

Standing by the patio door there is plenty of room in the cooking area of the kitchen for 3 people work as well as 4 to sit at the upper level of the island and 4-6 more at the table. What a great place to entertain guests.

The 2 apartment buildings were built in the mid 60’s. They had flat roofs that were leaking badly the owners needed to do some thing. A new flat roof would cost the same price as pitch roof with shingles, but the didn’t want a standard 2′ over hang.

We came up with a 6′ over hang with a Frank Loyd Wright Look to it by installing custom gutters built at a 45% angle on the faces as well as the exposed facisa board was rotated at a 45% angle.

On the under side of the overhang known as the soffit we install steel sheathing 24′x 30″ grooved soffit panels w/ baked on paint for a symbol of quality showing the area they the owners take pride in their buildings.

On the roof it self they wanted to draw more attention to the building, so we striped the roof with lighter shingles and hip lines.
If you would like to look at the project it;s located in South St. Paul south of 494 and 1 block west of Concord St. Just on the other side of fury motors (auto dealership) and can be seen from the freeway.

The first picture is the old deck.

We removed the decking and enlarged the size of the main deck. The decking is ironwood that comes from South America. The rails are iron pipe 2″ top rails and 1″ lower rails that can be painted or copper cladded.

When using cedar decking the cedar looks dirty and unfinished, even though you stain and treat it. You don’t want to use treated lumber for decking or rails because the wood is treated with copper arsenic, that will pass through the skin into your body.
I’ve built decks out of Trex decking, but the decking is unstable, in some cases it has expanded so much that the deck looks like a lake when it rains. Also trex molds you have to clean it yearly, but you can not use a power washer. So I’ve switched to Ironwood for decking with great results.

Comment: from a reader
I had hardy board siding installed on my house when we had it built 6 years ago and we have had a problem with moisture along the walls on the interior floors. the builder installed the hardy siding against the house wrap and the back side of the siding was not sealed or primed. do you think this might be our problem? The problem is only on the exterior walls inside the house.
The house is six years old, located in Mississippi Our location has had two rain falls in the past two months. The relative humidity for this time of year is the highest @ 70% t0 80% on the outside of the house. I am not sure what the humidity would be on the inside. We leave the heat and cool pump set on 75% when we leave and set it at 73% when we are home. The temp outside 80-90% during the day and 60-70% during the night. Paper back roll insulation in the walls and blown in insulation in the ceiling. We
noticed the problem when the house was a year old, we have re-caulked everything on the exterior, we have painted the exterior again, we have sealed the brick on the bottom portion of the house, I have set the fan motor on the heat and air to low, so it would run longer.
Answer
I’m assuming that the house has a go air conditioner with the power to drop the house temp and to maintain it at 72°F when the outside air is 110°F . This problem occurs mostly when the inside temp is at 72° to 95°, if so than what is happening is to much humidity from the outside is coming into the house though Fresh air intakes(makeup air) for the appliances and or exhaust fans as well as an air exchanger. What is happening with the Air conditioner it sounds like it is to large of a unit. When the air conditioner runs constantly(45 minutes per hour) it has the ability to remove the water from the inside air. But if the AC unit only runs 15-25 minutes per hour and make up air coming into the house, this excess hot air coming in to the house brings with it a high concentration of water in a vapor form.
Now the hot air carrying humidity is in the house it rushes to the ceiling , while the AC unit is running dumping cold air into the house. ( A quick lesson in physics; Hot air is light and rises and cold air is heavy and drops to the floor) As the hot air looses its temperature it must loss volume of water its holding to do this it has to condensate on something cold. In a house it is the A- coil inside the furnace. but if the temp inside the house is already cool and the AC unit is not running the A-coil in the furnace is warm now the air has to find a cooler surface to condensate on. In this house it is the floor next to the exterior walls because gravity is holding the coldest air at the floor line. The exterior wall location is because the heating and cooling supply ducts have already dispensed the cold air there now making condensation.
The solution
1. Run 1-3 dehumidifiers I now they are ugly and noisy
2. Down size your AC unit and install a 2nd AC unit in the Attic for 90° + days this will allow you to run your primary AC unit in your furnace longer and remove the excess humidity from the house.
3. If you have a air exchanger run the fresh air through a dehumidifier before bringing the air into the house. You can do this with any fresh air intake flex tubes.
4. Keep the house doors shut as much as possible A max. of 1 door opening per hour, 10 second open.
The siding is not the problem. the house wrap is not helping. In hot climates you must protect the house (wood structure) from excess humidity. That means you must seal wall sheathing surface with something that will not allow moisture to pass through even if the siding is nailed on. that means all nails and nail holes must be sealed. Than a layer of moisture control fabric must be installed that removes the excess humidity. tarpaper works best. The insulation with the paper on it is not good because it has the ability to hold the humidity in the stud cavity. In hot climate locations fiberglass, or mineral wool insulation is great because air can pass through the insulation allowing the stud cavity to dry out. Do not use poly on the inside walls in a hot climate because you will trap humidity in the stud cavities and will rot out your structural walls.

The IRC building code allows you to build you home an infinite number of different ways using a verity of materials. The traditional way of framing is called western platform framing. This entails building a floor on the foundation walls. Installing joists and floor sheathing. Wall framing; the walls are assembled on the deck of the floor, and then lifted up into place. Then the process repeats for additional floors. This type of framing is fast and cheap, it has some drawbacks:
Touch on photos to enlarge
1.The code requires 8″ of separation between the outside ground line and any type of wood product. The top of decoration rock is called the top edge of the ground line. In Minnesota, Iowa and Wisconsin there will be many houses that are going to be rotting away in the rim joist area.
2. Look how the load of the floor and wall is putting all the weight on the outer edge of the foundation wall making it act like a hinge point, Having a uniform load on the total thickness of the foundation wall makes it 4 times stronger. When you back fill against the foundation with poor drainage soil with no way to remove the hydro static pressure (ground water), you have made an easy way to have your foundation wall to buckle. If you look you will see before it buckles it will bow or crack horizontally and or diagonally.

There is always a better way to build, in this photo the main floor walls are pushing down on the outer edge of the foundation wall and the floor is pushing down on the interior part as well as holding the wall from being pushed inward.

Improper sealing around heating, plumbing, and electrical penetrations allows air to flow into attic spaces.
This air carries high a volume of humidity with the air, and as it comes into the attic, if the temp is below 32° it freezes onto the underside of the roof sheathing and the trusses.
During the spring thaw, it compacts the insulation, sags the sheetrock ceiling, and stains the ceiling.
When the humidity level is high it enters the edges of the roof sheathing, swelling the edges giving the look of big rectangles on the roof. If the back side of the shingles get wet then the shingles curl.
The exterior of the house must have air, trees overhanging the house stop air movement and keeping the humidity level very high.
This will cause the roof to fail 5-15 years earlier than it should.

Raw sewage (black water) flows from the house to the first of 2 septic tanks. The weighs are trapped in this tank where they brake down. Once the liquid drains 2 a 2nd tank and some heavies or sediment was able to leave the first tank the 2nd tank catches it. When the liquid leaves the 2nd tank its now call gray water ready to the drain field.
When entering the drain field the gray water runs through the lateral pipe to each of the drain beds equally. Each bed has 4″ pipes with about 2 -1″ holes every 6” allowing the gray water to spread into the river rock. Where the drain field does its work is not in the rock but on the edge of the rocks and the meeting of the sand a 1/8″ membrane is formed that eats the bacteria out of the water.
Once your drain field is installed do not hurt or damage the edges of the sand and rock bed of your drain field.

L You think you found the perfect lot?
1 What’s next?
Are your finances in order? Get reproved from a bank and find out what you can comfortable afford in your budget for a house. Remember there will furnishing you will have to buy, and maybe a yard to install, a minimum of $5,000.00 – and up to 10% of the house price.
2 Who buys the lot?
Always let the contractor buy the lot, it protects the homeowner, 1. What if the lot has bad soil or contaminates in the ground. The contractor has a way of discharging the lot. 2. what if the under ground water table is too high. The lot setbacks and other lot rules set forth by the city doesn’t allow your house to fit on said lot.

Who should build your remodel house?
The homeowners doing it themselves.
1 I was called to a house in 03 to a house that was built by the homeowner. They called with a problem of water in their basement. They had a perk test done the property fore the drain field part of the sewer system and they were told the perk wraith of the soil and at what level there was water and what level to install the drain field at. When it was time to build about 3 months later being a dry summer they dug 3 1/2 feet below the drain field to set the footings.
The next 2 years were dry but the summer of 03 was a couple of above average rainfall that spring and they had 3’ of standing water in their basement.
Saved about 20,000.00 on contractors fees and lost about 26’ x 42’ area in a lower level or resell $54,600.00 value.
2 I was witness to a homeowner who built his own house in the early 80’s he was a painter and what’d to build a big house and then become an insurance sales man. He subcontracted out most of the work and then he trimmed out his house (installing all the millwork). It was a bad trim job and he was proud of it with gaps of 3/8-1/2” in all the joints. The living room was the last room done and he hand the joins 1/8” gaps and very proud.
3 I helped a couple to frame, side & roof there house and he was going to do the rest the print came from house package deal, and he had to do was to supply the labor. Well when he was done the gentleman that did the taping called the house from Hades. The gaps in the corners were bigger than the narrow part of my framing hammer 1 1/4” the rock job was so bad they textured sprayed the walls and ceiling to cover problems. The basement looked like
the Greek parathion. 15-20 steel posts making it hard to finish the basement, and the trim was poorly done.
4 I feel bad for people who think they can do it themselves. Subcontracts love to sign up homeowners for work to have fill in work when their contractors are slow. This is the first of many examples. If you want to build the house in the summer and starting in June with the excavating the excavators are super busy until July from late winters work (frozen ground and road restriction shut down most of work) of final grading and installing sewer systems. By the time they finish their house they are at lest 6 months past their closing date and they lost their loan lock. Most bid are only good for 30 days and the busier it gets the prices good up, now they are at lest 10-15% over their budget. And there marriage is severally stressed.
2. Using a reputable contractor.
Looking for a good contractor is very hard. You can call the following:
Minnesota Commerce Department
The Better Business Bureau
The Chamber of Commerce (the contractor pays into it so they are a bust)
The best way to find a good contractor is by word of mouth
Interview your contractor to see if your comfortable to deal real close with him/her daily for months/years after the house is done.
Get a complete client list (the good and bad clients) of all work that has been done by the contractor for the last 5 years.
Remember some client’s thing the contractor is god and other think the same contractor is the son of the devil. Please go and look at some of the work that he/she has done.

3 The right to understand your contract.
A The “contract”
The contract is to keep both parties in check and on track with what is written in the contract. If the contract is not written in 10-point type it is not a legal document as to the State of Minnesota Law.
After signing the contract you have 3 Business days with a written letter delivered to the office before the end of normal of the 3rd day. You have a legal right to back out of the contract by Minnesota State Law.
B Who is working on your behalf.
B1 There a many different types of people you could be working with.
1. A Realtor may be involved in securing a lot 2. An architect may be involved in the design of the print of the home 3. A home interior Designer could be used in the picking out the different styles and operation flow from bathrooms, to kitchen and every thing in between.
4. A home interior decorator should be used in the picking out the different finishes from wall textures to flooring to lighting and every thing in between.
5. You may need a representative to work on your behalf if you are out of reach (over seas for your company etc.)
B2 A good contractor can save a client money and headaches
1. There are different types of people trying to separate you from your money.
2. There are people out there that like to cease problems. A bad subcontractor or a subcontractor’s employee(s) can make a mess of a house.
3. The general contractor should have the final say as to who is on the team.
B3 Experienced first hand: A bad interior designer can cause problems on many fronts
1. Trying to take over the job -usurping the contractors authority
2. Telling the client what they want instead of how thing work and possible ways to do them.
3. Under cutting other subcontractors behind their backs and casing friction between the client and the different crews.
4. And finally at the end the interior designer turned on the client.
C What are in the details
Details take time to read and comprehend what is being said
1. If they hand you a print of your house and say to you what you are going to get, you are going to be taken.
2. If you have a brief description of what the details are, you are going to get taken.
3. If they tell you that you have generous allowances in floor coverings, cabinets & counter tops, millwork, lighting, appliances, landscaping, you are being taken.
4. Now look at the spec sheets as we offer to show you what you’re going to get in your house.
D When things go wrong
What if the worse thing happens during the building stage?
1. What if your spouse dies or gets very sick during the project.
2. What happens when you & the contractor are at odds on every thing?
3. What happens when the contractor says one thing and you desire the other who breaks the tie?
In a good building contract there shall be a statement covering this items.

4 Knowing the Law
A Change Orders
The Law requires all contractors to use change orders for any and all changes made to the original contract listing the original price first than the additions and a new total of the project. Than the client must sign it before the changes can begin. It’s the law.
B Mechanic’s Lien Rights
Receipt and waiver of mechanic’s lien rights; As full and final payment for all labor and material furnished to the following described real property:(legal description, street address or project name) and for value received hereby waives all rights acquired by the undersigned to file a mechanic’s lien against said property for labor and material furnished to said property.
C Exercise Lien Rights
If the client wants to exercise this lawful right, the client now becomes solely responsible for all payment due said party or parties. Builder is no longer responsible for any and all payments due said party or parties.
The client(s) have exercised their lawful right to withhold a portion of the payment due builder in order to directly pay the party and or parties which have previously sent written notice of lien rights to the client(s).
D Quit Claim Deed
In a quitclaim deed, the buyer acquires only the seller’s rights to a piece of property. The Seller bears the loss if someone has a claim against the property, or if the seller is mistaken in the amount of property he owned.

Touch on a picture to enlarge
You are looking at 2 cross sections as to how to build a frost footing.
The first picture shows how 98% of all house frost footings are installed. With this type of design there are some problems.
1. Where there is a 42” frost footing required the install 1-7 1/2” high footing 4- 8” blocks which = 40” with mud joints 41 1/4”. If they install a 1/2 high block the total height is 44 3/4” no problem except the code requires the grade height to 8” lower than wood framing and or wood siding. Making the frost footing only 41 1/4 with a high block and no wood siding. But you house has wood siding and no half high block the frost footing is now 36 1/2”. So in picture 1 the water is up to the top of the soil on the exterior. When it freezes in the winter we know water will expand and increase its mass crushing the insulation decreasing the R-value and allowing the water to freeze to the footing, which will move it, laterally inward or vertically which ever is easier.
2. As the temperate of your frost footing drops in the winter your concrete slab will also reflect how cold it is outside.
3. The Rigid foam insulation must be covered because the ultraviolet light from the sun will break down the insulation most contractors cover it with aluminum sheathing. Aluminum and does not like concrete or salt, it will corrode and eat the aluminum. Yet they pour concrete up against the aluminum shield and don’t tell the owners of the houses not to salt their sidewalks.

A lot contractors can build a house, the lady of house will change the structure to a home. The question is “are you happy with your surroundings did you get what the contractor envisioned for you or did you get 4 walls and a roof”.
In the first hours of interviewing home building contractors, this is the time to ferret out if the contractor, is out for his wallet or to gain a friend. Remember once you sign a contract with him/her, the working relationship will late up to 10 or even 12 years. The house may be done in 3-6 months, but the warranties and call back could be a nightmare.

The state says, “installing the drain tile on the inside of the footing is known as cosmetic.”

The code also requires that the contractor installs 4 inches of rock or gravel under concrete floor. But if you have a high groundwater table on your lot 4 inch of rock is not enough. If water touches the concrete floor it will wick up to the topside of the floor and evaporate into the house air rising your humidity level. This in turn creates other problems in the house. If there is carpet on the concrete floor it now has mold growing in it.
Moisture freezing on the windows in the winter time. By installing 1 1/2 inch rock you leave larger voids under the floor not giving the water a chance to touch the concrete floor.
Now installing draintile around the foundation on the inside is known as cosmetic it also is wise and while you are installing draintile running additional draintile lines is just prudent. The cost worth the investment of only about $ 150.00.

Looking for alternative ways to keep plumbing prices down. One way is to install Wirsbo water supply line instead of copper.
Yes copper is great easy to repair, add on to, or even change the design of plumbing as it is being installed. But the price, its great if you are Bill Gates, or a basketball player in the NBA. But for the rest of us there are alternative types of plumbing supply lines.
The Wirsbo system in some ways better than copper.
When water freezes to ice water expands 10% than when it is a liquid form. When water freezes in a cooper pipe it will split the length pipe to relieve the excess pressure. While on the other hand Wirsbo piping is designed to expand 200% larger than the water volume at 100 PSI meaning that it Wirsbo pipe will not fail.
The two draw backs of using Wirsbo piping new tools and instructions for installation you must learn. 2. Wirsbo unlike copper or Iron pipe doesn’t conduct electricity through it, you will need to run a ground wire back to the electrical panel and find a 2nd grounding location–like one of the following a cast iron well pipe, a 5/8″ or larger rebar which is barried in the concrete foundation of your house.
What is nice about Wirsbo there is less hot or cold transference throw the piping intern bring hotter water to the sinks and showers faster than with metal pipes.

Gypcrete is a lite weight cement mix which uses gypsum instead of sand and a high quality Portland mix making gypcrete.
In commercial applications Gypcrete is used as a sound deadener and a fire retardant between floors.
In a residential setting it is normally used to cover over infloor water heat pipes.
The gypcrete companies can pour the gypcrete at a minimum of 1/2”. A good thickness is 1” or more, this includes pouring over all types of pipes. (know this there is no law to protect the homeowner about gypcrete). Gypcrete must have a load bearing floor under it to support it, and the finished floor and it live load (furnishings and people). If you are installing the gypcrete 1 1/2 or less – it must bond to the structural floor below. If you need insulation under the gypcrete, install the insulation than install 4’ x 16’ wire panels with 6” x 6” grids anchored to the floor below the insulation with the anchor not less than 2’ square on center. The wire mesh helps stabilize the gypcrete and keeps it from braking up in the future.
