Seal Air Leaks

Air Sealing

Sealing the shell of your home—outer walls, doors, ceiling, windows and floors—from air leaks is one of the easiest ways to increase comfort and energy efficiency. Sealing air leaks reduces drafts, controls moisture, keeps out pollutants and improves overall comfort.

Many air leaks and drafts are easy to find because they are easy to feel, like those around doors and windows. However, hiring a contractor to perform a blower door test, which pressurizes and depressurizes your home to measure air leakage, can help you find many of your home’s hidden leaks. (Find out more about sealing air leaks.)

Energy Trust offers cash for sealing air leaks in homes built before 1982. Read more below about applying for cash incentives and hiring a contractor.
