Insulation
Services
Massachusetts homes — especially older properties in Dedham — often have little to no wall insulation and attics that fall far short of today's code requirements. Dedham's housing ranges from historic 18th and 19th century homes near Dedham Square to mid-century colonials in Endicott and newer construction near Legacy Place. Older homes require careful plaster restoration and historically appropriate finishing work, while newer homes generate strong demand for kitchen remodeling and ADU construction. Boston Smart Plastering installs all insulation types to current Massachusetts Climate Zone 5 standards, with proper air sealing alongside every project. Dedham homeowners may also qualify for Mass Save rebates of up to $2,000. Dedham is 9 miles southwest of Boston off Route 1 and I-95, easily accessible and a core part of our Norfolk County service area.
Frequently asked questions
How much does insulation cost in Dedham MA?
Attic blown-in insulation in Dedham 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 Dedham homeowners — ask us about eligibility at your free estimate.
Can you insulate existing walls without removing drywall in Dedham?
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 Dedham's older housing stock near Dedham Square, Legacy Place, Endicott neighborhood, Mother Brook, Riverdale where opening walls would be disruptive.
