Mainely Insulation

Mainely Insulation is a Biddeford-based insulation contractor serving homeowners and commercial clients across Southern Maine. Led by Scott Regan and crew lead Trey Gagne, our team installs and improves residential and commercial insulation — spray foam, dense-pack cellulose, fiberglass, vapor barriers, and full air sealing and ventilation work. Whether you are upgrading an older home to cut heating costs, sealing a new build to code, or tracking down the moisture problem behind the mold, we walk the job in person and give you a fair written estimate before we touch a thing. We are spray foam certified, fully insured, and we extend a 5% discount to first responders and veterans. "Insulation without ventilation leads to condensation" — we get the whole envelope right, not just the easy part.
