Insulation
Services
Massachusetts homes — especially older properties in Randolph — often have little to no wall insulation and attics that fall far short of today's code requirements. Randolph's housing stock includes substantial post-war construction — 1950s through 1980s single-family homes and multi-family properties throughout the town. Older homes generate demand for plastering, drywall, and painting, while the active real estate market drives kitchen and bathroom remodeling, flooring installation, and junk removal for property turnover. Boston Smart Plastering installs all insulation types to current Massachusetts Climate Zone 5 standards, with proper air sealing alongside every project. Randolph homeowners may also qualify for Mass Save rebates of up to $2,000. Randolph is 12 miles south of Boston off Route 28 and accessible from I-93, centrally located in our South Shore service footprint.
Frequently asked questions
How much does insulation cost in Randolph MA?
Attic blown-in insulation in Randolph 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 Randolph homeowners — ask us about eligibility at your free estimate.
Can you insulate existing walls without removing drywall in Randolph?
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 Randolph's older housing stock near Randolph Center, Memorial Park, Stetson Pond, North Randolph, South Randolph where opening walls would be disruptive.
