Seal Air Leaks
Sealing the shell of your home—outer walls, doors, ceiling, windows and floors—from air leaks is one of the easiest and most cost-effective 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.
