The Effect of Air Leaks

Heating and cooling can account to up to 54% of your energy consumption, depending on your home, air leaks may represent more than half of that cost. Air sealing your home is not just a money-saving endeavor, however. Air leaks can damage your home’s structural integrity over time. The constant exposure to the outside air can lead to the development of mold, water damage and pest infestations. This is especially concerning in Florida where humidity levels can lead to trapped moisture in your home. The extra moisture can damage your house’s foundation if not properly treated.

Detecting Air Leaks

Now that we have established the dangers of air leaks, let’s move on how to rectify the problem in your home. Air sealing cannot begin without properly detecting air leaks. Homeowners have several options from free to moderate cost detection methods. The quickest way to test for air leaks is by using your hand. Place it on corners or other outside facing entrants in your home such as doors or windows and feel for a breeze. Candles can also be used for detecting smaller leaks such as around electrical outlets and light fixtures. For the technically apt, an air leak detector might be a good investment for a more accurate air leak assessment. The most accurate air detecting method is to hire an HVAC contractor to perform a blower door test.

Air Sealing Your Home

Air sealing around your house is not a clear-cut process. Different sized leaks call for different methods to seal them. Spray foam is excellent for ceiling around pipes, plumbing, wall joints, and other areas less than 5 inches in length. The exterior of the home can be sealed with rigid foam which is more resistant to the environment and can be applied to the roof, a major source of air leaks. For smaller leaks such as cracks and gaps less than a quarter inch wide, caulking is the preferred method for air sealing. Doors and windows represent a different challenge as they have components that move frequently. Weather stripping is the recommended method to keep windows and doors sealed against leaks.
