Graham Built Corp.

Graham Built Corp operates as an insulation contractor serving Pembroke and surrounding Massachusetts communities. The business holds a 4.9 rating across 54 reviews, reflecting consistent homeowner satisfaction with air sealing and weatherization projects. Their service menu covers attic and basement air sealing, various insulation types including blown-in cellulose and fiberglass, duct system work, and complementary offerings like exterior weather stripping and attic stair covers.

What distinguishes this contractor is their participation in the Mass Save program, which enables qualifying homeowners to access rebates on insulation and air sealing work. The team handles mini-split and heat pump installations through their East Coast Mini Splits & Heat Pumps division, offering ductless systems suited to homes without existing ductwork. Same-day installation availability sets them apart for homeowners facing urgent efficiency issues.

Customer reviews highlight specific team members including Jim and Tyler, who identified a pipe issue and delayed work until it was resolved, then completed insulation to code. Joe and Rildo earned recognition for professionalism during a Cape-style home project requiring dormer access through four openings, with patch work described as paint-ready. Reviewers consistently note cleanup after insulation work, a contrast to experiences shared with other contractors. Nancy and Chris in the office facilitate scheduling, according to feedback from multiple customers.
