Across Brunswick, Topsham and Bath, we insulate older homes in town, capes and colonials in the neighborhoods, coastal homes out on Harpswell, and new builds and additions throughout the Midcoast.

In Brunswick, Topsham and Bath, many homes are older capes, colonials and in-town houses with leaky attics and damp basements. Coastal wind finds every gap, so air sealing matters even more here.
Out on Harpswell, Phippsburg and Woolwich, damp air off the water makes basements and crawl spaces musty. Encapsulation and foamed foundation walls keep that moisture out of the house.
We also insulate new builds, additions and garages across the Midcoast while the walls are open.

Learn more βCoastal homes deal with steady wind that pushes cold air through every gap in the walls, windows and foundation, plus damp air that settles into basements and crawl spaces. Insulation alone slows heat but doesn't stop that air.
Spray foam stops the air as it insulates, which is why it works so well on rim joists, foundation walls and roof decks in coastal homes. Encapsulating a damp basement keeps moisture out of the framing and the living space.
The result is a house that feels less drafty on windy days, stays drier, and burns less fuel.
From Downtown Brunswick to Durham β we serve all of Brunswick & Topsham and the surrounding area:
Insulating an existing attic or basement usually doesn't need a permit, but new construction and additions in Brunswick, Topsham and Bath are inspected, and shoreland zoning applies along the water. Foam in basements and attics may need an ignition or thermal barrier depending on use. We check what applies and include it in the quote.
Insulation and air sealing can qualify for Efficiency Maine rebates. We'll show you what you likely qualify for at the quote.
Insulation slows heat, but drafts walk right through it. We seal the leaks at the attic floor, rim joists and foundation first, then insulate.
Closed-cell foam for basements and rim joists, cellulose where it's the better value, open walls sprayed while they're open. Not one product for everything.
