Air sealing the building envelope is one of the most critical features of an energy efficient home. The Blower Door test combined with a smoke test and infrared camera imaging from our “Whole Home Performance Check-Up” will determine how leaky or tight your house is. Leaky areas that are detected need to be sealed in order to mitigate air infiltration. This will increase energy efficiency, lower utility bills, and promote a healthier indoor air quality.
Notorious spots for leaks in the building envelope are: attic hatches, recessed lights, gaps around doors and windows, crawl spaces, and electric outlets. Building Doctors are experts at locating and sealing these trouble spots. We use everything from caulk, expanding foam, weatherstripping, gaskets, and door sweeps to seal these air infiltration points.
