Air Sealing
Stop air leaks and drafts for a more comfortable, energy-efficient home.
What Is Air Sealing?
Air sealing is the process of finding and closing gaps, cracks, and openings in your home's envelope—the barrier between conditioned indoor air and the outside. Even small gaps can add up to the equivalent of leaving a window open year-round.
Using specialized equipment like blower doors and thermal imaging, our BPI-certified technicians identify air leaks and seal them with the appropriate materials—caulk, foam, weatherstripping, or rigid barriers depending on the location and size.
Did You Know?
The average Maine home has enough air leaks to equal a 2-square-foot hole in the wall. Imagine heating your home with a hole that size—that's what you're doing without proper air sealing.
Benefits of Air Sealing
Professional air sealing delivers immediate and long-term benefits for your home.
Lower Energy Bills
Air leaks can account for 25-40% of heating and cooling costs. Sealing them saves money.
Improved Comfort
Eliminate cold drafts in winter and hot spots in summer for consistent temperatures.
Better Indoor Air Quality
Keep dust, pollen, and outdoor pollutants from entering through gaps and cracks.
Moisture Control
Prevent humid air from entering and causing condensation, mold, and rot.
Quieter Home
Reduce outside noise from traffic, neighbors, and weather.
Rebate Eligible
Air sealing often qualifies for Efficiency Maine rebates when combined with insulation.
