Sure Seal

Sure Seal is an Insulation contractor serving the Boston area, specializing in air sealing, blown-in cellulose, and spray foam to boost comfort and lower energy bills. Schedule a home assessment and ask for a written scope with target R-values by area (attic, walls, basement) plus photos or infrared imaging to verify coverage. Compare material options and confirm details on ventilation, fire barriers, and moisture control to avoid issues like ice dams and condensation. Before you commit, ask about project timelines, available rebates (such as Mass Save), warranties, and post-job cleanup so you know exactly what to expect.
