Open-cell and closed-cell spray foam for attics, rim joists, crawl spaces, cathedral ceilings, and wall cavities in Hingham. Air-tight, moisture-resistant, highest R-per-inch available. Typically out-of-pocket; paired with Mass Save air sealing where that yields the best combined cost.
Attic-plane, rim joist, top-plate, and chase sealing to eliminate stack-effect losses. This is the highest-ROI measure in most Hingham homes and is typically covered at 75–100% by Mass Save.
Dense-pack cellulose, blown-in fiberglass, and rigid-foam envelope work. These are the core rebated measures under Mass Save — we scope, install, and handle the paperwork.
Hang, tape, and finish for new construction, renovations, and post-insulation wall restoration in Hingham. Level 4 and Level 5 finishes; residential and multifamily.
Veneer plaster and traditional three-coat work for historic restoration in Hingham. Texture-matching for pre-1950 homes where drywall would read wrong.
Premium interior painting with proper prep and quality materials. Walls, ceilings, trim, cabinetry. Available standalone or as the finish phase of a full Smooth renovation in Hingham.
Open-cell runs about $0.45–$0.75/board foot; closed-cell $1.00–$1.75/board foot. A typical attic project runs $2,000–$5,000 and a whole-basement retrofit $3,000–$7,000, depending on square footage and access. We give you a firm written quote before any work starts.
Most residential projects in Hingham are completed in one working day. Larger homes, multifamily buildings, or jobs that include demo or rigid-foam prep may take 2–3 days. We provide a clear timeline before we begin.
When installed by trained crews using proper ventilation and cure time, spray foam is safe and chemically inert once cured (typically 24 hours). We follow manufacturer re-entry guidelines and won't return the home to occupancy until the foam is fully cured and ventilated.
Yes — typically 24 hours after the spray application. We coordinate timing so you're out for the minimum necessary cure window. Pets and plants must also be out during that period.
Air sealing stops uncontrolled air leakage (attic bypasses, rim joists, top plates). Insulation slows heat transfer through building assemblies. Air sealing first, then insulation — done together, they cut heating and cooling loads 15–30%.
Mass Save® rebates cover air sealing, attic insulation, wall insulation, and basement insulation at 75% off (100% income-eligible) using approved cellulose, fiberglass, or rigid foam — not spray foam specifically. Smooth is a Mass Save®-aligned contractor, so we can complete rebated weatherization AND non-rebated spray foam under the same job if that's the right mix for your home.
For most rebated measures, yes — the no-cost assessment identifies the scope and unlocks the rebate. For pure spray foam work (not rebated), we can give you a quote directly without an assessment.
