About This Service
Air sealing targets the small gaps that let energy escape, around windows, doors, framing, electrical outlets, plumbing penetrations, and more.
We apply caulking, spray foam, and weatherstripping to these weak spots to prevent air infiltration and improve indoor air quality and HVAC efficiency.
When combined with attic or wall insulation, air sealing becomes one of the most powerful ways to reduce your home’s energy loss and keep temperatures consistent.
