If you’re feeling drafts, especially near windows and doors, weatherizing may be in order to make your home more energy efficient and lower your energy bills in the process. Whether you have an older home or are working on a new build, weatherizing your doors and windows is an easy way to lower air leakage in your home.Most DIY-inclined people have installed their own weather strips on doors and windows, but what lurks behind your window and door trim? Upon inspection with a thermal camera, the areas around doors and windows are on the top of the list for air leakage, right behind where your drywall meets your top plate.Removing window and door trim to seal with caulk and in the case of larger gaps, spray foam insulation, can reduce air leakage and increase your home’s comfort. Here’s the secret: many companies advertise and install energy efficient windows for an extreme cost, but the actual R-Value difference is very small. Many customers feel a great difference in comfort, however, but it is due to the installer’s air sealing around the installed windows rather than the windows themselves.
