Seal hidden air leaks to improve comfort, reduce energy loss, and prevent moisture issues in your home.
Most homes have dozens of small air leaks in the attic—from recessed lights and wiring holes to vent pipes and attic hatches. You may not see them, but they have a major impact on how your home performs.
These gaps allow heated air to escape in the winter and hot attic air to enter in the summer, forcing your heating and cooling system to work harder than it should.
Over time, this leads to higher energy bills, uncomfortable rooms, and moisture issues that can affect both your home and indoor air quality.
Air sealing is the foundation of a properly performing attic—but it’s often skipped or treated as an afterthought.
We start by identifying and sealing the hidden gaps and penetrations that allow air to move between your home and attic. This step makes the biggest difference in comfort, efficiency, and long-term performance.
Once air leaks are properly sealed, insulation and ventilation can do their job the way they’re supposed to—resulting in a more consistent, efficient, and durable home.
Air leaks are usually found in the same problem areas across most homes. These include openings around wiring and plumbing, recessed lighting, attic access points, and gaps along framing and top plates.
Even small openings in these areas can add up to significant energy loss over time, especially in older New England homes.
Sealing these leaks helps stabilize temperatures throughout your home, reducing drafts and making rooms more comfortable year-round.
It also reduces the amount of conditioned air escaping, which can help lower heating and cooling costs.
In colder climates, proper air sealing plays an important role in controlling moisture and reducing the risk of condensation and ice dams.
Yes. Insulation slows heat transfer, but it doesn’t stop air movement. If air leaks aren’t sealed first, insulation can’t perform properly and you’ll continue losing energy.
Most homes do. Common signs include uneven temperatures, drafts, high energy bills, and rooms that are difficult to keep comfortable throughout the year.
In most cases, yes. Sealing air leaks can significantly improve comfort, reduce drafts, and help stabilize temperatures across your home.
Yes. Air leaks allow warm, moist air to enter the attic, which can lead to condensation. Sealing these leaks helps reduce moisture buildup and related issues over time.
Most air sealing projects can be completed in a single day, depending on the size and condition of the attic.
The work is contained to the attic, and we take care to protect your home and leave the space clean when the job is complete.
Yes. Air sealing reduces the amount of warm air escaping into the attic, which is a major cause of ice dams in colder climates like Maine.
