Spray Foam Insulation

McGrath Construction provides professional spray foam insulation services throughout Central Massachusetts, including closed-cell spray foam for attics, roof decks, crawlspaces, garages, additions, and full building-envelope upgrades. Spray foam insulation improves energy efficiency, moisture control, indoor comfort, and overall building performance.

We approach insulation from a contractor’s perspective, understanding how ventilation, framing, HVAC systems, and moisture management all work together. Our spray foam solutions are designed to help homeowners reduce energy loss while improving comfort and long-term durability.
