Insulation
Services
Massachusetts homes — especially older properties in Somerville — often have little to no wall insulation and attics that fall far short of today's code requirements. Somerville's housing stock is predominantly late Victorian and early 20th century — triple-deckers, two-families, and rowhouses throughout neighborhoods like Davis Square, Union Square, and Winter Hill. These older properties have original plaster walls, aging mechanical systems, and kitchens and bathrooms that are prime candidates for renovation. Boston Smart Plastering installs all insulation types to current Massachusetts Climate Zone 5 standards, with proper air sealing alongside every project. Somerville homeowners may also qualify for Mass Save rebates of up to $2,000. Somerville borders Cambridge and sits just 4 miles northwest of Downtown Boston — one of our most active and accessible inner-suburb service communities.
Frequently asked questions
How much does insulation cost in Somerville MA?
Attic blown-in insulation in Somerville typically runs $1,500–$4,000 for an average home. Spray foam for rim joists runs $800–$2,000. Mass Save rebates may significantly offset the cost for Somerville homeowners — ask us about eligibility at your free estimate.
Can you insulate existing walls without removing drywall in Somerville?
Yes. We use a blown-in technique — small holes are drilled, cellulose is blown into the wall cavity, and the holes are patched invisibly. This is particularly valuable for Somerville's older housing stock near Davis Square, Union Square, Assembly Row, Winter Hill, Magoun Square, Ball Square, Teele Square, East Somerville where opening walls would be disruptive.
