John P. Insulation

John P. Insulation is an Insulation contractor serving the Boston area, offering attic, wall, and basement upgrades to cut drafts, noise, and energy costs. Book an on-site estimate and ask for an air-sealing plan with blower-door or infrared diagnostics so you can see exactly where heat is being lost. Discuss material choices (cellulose, fiberglass, or spray foam) based on your home’s age, moisture levels, and ventilation to prevent condensation and ice dams. Request a detailed, written scope with target R-values, rebate guidance (e.g., Mass Save), timeline, warranty, and cleanup plan so you know the deliverables before work begins.
