Master Spray Foam

Master Spray Foam is an insulation contractor serving Boston and nearby areas, specializing in spray foam solutions for attics, basements, crawl spaces, and whole-home retrofits to reduce drafts and energy costs. When you contact them, ask for a written quote that details open-cell vs. closed-cell foam, targeted R-values, air sealing scope, removal/cleanup, and warranty terms. To get the best value, confirm licensing and insurance, SPFA-certified installers, code compliance, and whether they can help you access Mass Save rebates or financing. Request a clear timeline, a ventilation and moisture management plan (vapor barriers, dehumidification where needed), and before/after photos so you can schedule around curing time and verify results.
