Even tiny air leaks can add up if there are a lot of them in your Northwest Arkansas home. To improve heating and cooling efficiency year-round, you need to find and fix these tiny leaks, which can be located everywhere from the attic to the basement. Here are some tips on locating and plugging up air leaks around your home.
Locating air leaks
Before you can fix leaks, you first must find them. Common locations for leaks to occur are around:
Sealing air leaks in your attic
The most significant savings come from sealing the largest holes first. Leaks between your living space and the attic are likely to be most profound:
Dirty insulation is a sign that air is passing through it, indicating a leak. Fill any openings you find with caulk (for 1/4-inch or smaller gaps) or spray foam (for up to 3-inch gaps).
Sealing air leaks in your basement
A leaky basement is exacerbated by a leaky attic because of something called the chimney effect. As leaks in the attic floor cause air to rise out of the living space, leaks in the basement compensate for the pressure difference by allowing outside air to enter. You can help deter this by sealing:
You should use spray foam or caulk to seal these areas, depending on the size of the gaps.
