Preventing cold air infiltration and warm conditioned air from escaping can be just as important as insulation.

Air Sealing

One of the most important things we can do for you is testing the air leakage in your home. Blower door testing helps us quantify and prioritize air leakage issues. The Department of Energy estimates that on average 20% of heat loss is due to air leakage. Preventing warm air from escaping and cold air from infiltrating the building is key to improving efficiency and year round comfort.

With very old colonial-era housing stock in Vermont, air leakage can be even more substantial. Old field stone foundations, lathe and plaster walls and ceilings, and post and beam construction have too many air-sealing opportunities to name. Even newer construction suffers from air leakage issues. Properly diagnosing and sealing of air leaks is one of the most cost effective ways to resolve comfort, cost, and ice dam issues.

With our experience and diagnostic tools, we can effectively locate and remedy air leakage issues by sealing these pathways. Using spray foam, caulk, metal flashing, and rigid foam board we can prevent conditioned air from leaving and unconditioned air from infiltrating the building. The rebate program is also based on measured air leakage reductions because it’s one of the most cost effective means of reducing fuel use.
