How are air leaks fixed?

We use a variety of methods to assess and rectify air leakage issues for homeowners. The key is to provide controlled ventilation, while reducing the air leakage as much as possible.

Determining the source of air leaks

Firstly, we go through your home to detect air leaks. You will likely know where most of these are, because they are pretty easy to feel. Holes in attics, basements, or crawlspaces, on the other hand, are in areas less likely to be frequented by a homeowner and may be hiding big holes and cracks.

Our next step is to perform duct blasting or blower door testing. A large and powerful fan is used to pull the air out of the house, lowering the air pressure inside. As we monitor the return of the air pressure to a normal level, we can assess the amount of air flowing through your home, and the opportunities available for improving air sealing.

Fixing the affected areas

Once we’ve located the problem areas, we can use a variety of products to seal your home. Caulk, spray foam, and weather stripping will be used for smaller air leaks. Larger holes will be repaired with rigid board insulation or similar materials. Areas such as gaps around chimneys or furnace flues will require sheet metal or caulk specialized to handle high temperatures.

When we are done air sealing your home, not only will you be more comfortable, but your wallet and banking accounts will show you just how valuable air sealing truly is.
