Insulation & Air Sealing in Southern ME & the Seacoast NH

Insulation and air sealing work best together. Air sealing closes the hidden gaps that let warm air escape, such as attic bypasses, top plates, rim joists and openings around chimneys, pipes and wiring. Insulation then slows the heat that moves through attics, walls and crawlspaces. The result is a more comfortable home with fewer drafts.

We are an insulation contractor as well as energy auditors, so we can help you install the improvements recommended in your home energy audit. A blower door test shows where air sealing will do the most good, and crawlspace repair uses spray foam insulation and vapor barriers.

Rebates for insulation and air sealing may be available. See Maine rebates and New Hampshire rebates. We serve York County, Maine, including Berwick, Kittery, York, Wells and Sanford, and the New Hampshire seacoast, including Portsmouth, Dover and Rochester. Call (603) 828-2290.
