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.
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.
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.
