Insulation

Insulation is one of the best, most cost effective things you can do to your home.  Start with the attic, then the walls, and then do the floor last.  The floor is only marginally cost effective and should be done as a comfort issue rather than a utility saving measure.

Attic Insulation

We will examine the level of insulation in your attic. In most cases it should be between R-38 and R-49 depending on your heat source. That’s 12 to 16 inches of insulation. If you need more we can do that . We’ll install blown cellulose or fiberglass insulation on top of what you have. We can also use fiberglass batts in special circumstances, if you prefer. Some people think that this should be a “do-it-yourself” type project. But realize that we buy insulation by the truck & trailer load which means that our installed price can be not much more than you would pay at the building supply store just to by the insulation.

Wall Insulation

We can do a couple quick tests and determine if your home has any insulation in it’s exterior walls. Most houses built before 1970 do not have any. It is a simple process to install retro-fit wall insulation. We start at the top and drill a hole between the studs. We put a “plumb bob” in the hole (a string with a weight on the end) and see how far down it goes. If there are blocks we can tell and then drill again just below them. Repeat until we get to floor level. We then blow cellulose insulation into the wall cavity under slight pressure until the cavity is full. The pressure is just enough to pack the insulation tightly but not enough to blow the wall covering off the wall. A cork is placed into the hole and recessed, and a non cracking filler is put on top of the cork and left just a little high. It’s up to the customer to do some light sanding and prime and paint the spots.
 

Floor Insulation

We will install floor insulation from the crawlspace of you home. R-19 fiberglass batts are placed between the floor joist and a special metal rod is inserted. The rod is made of spring steel, has sharp ends and is a little longer than the space between the joist. The spring action forces the points into the wood and holds the insulation in place. In some instances the distances between the joists is larger than standard, up to 48” wide. The insulation can then be held in place by driving nails into the bottom of the joist and then stringing wire between them.
