Mass Save in MedwayEligible

Medway is served by Eversource, so homeowners qualify for the full Mass Save program. The first step is a no-cost Mass Save Home Energy Assessment, after which Mass Save typically covers 75-100% of approved insulation and air-sealing costs (100% for income-eligible households), with the 0% Mass Save HEAT Loan up to $25,000 covering the homeowner share. In Medway's older village homes, an assessment commonly flags knob-and-tube wiring that must be cleared before dense-packing, and pre-1981 vermiculite attic insulation that may need testing and abatement first.

Insulation in Medway — what to know

Permits in Medway

Insulation in Medway usually needs no standalone building permit, but the contractor should hold a Massachusetts HIC registration, and related structural work requires a licensed Construction Supervisor. Mass Save rebates require a participating or approved contractor. Spray foam must meet state fire and ignition-barrier code, with a thermal barrier in finished space. In older homes near the village centers, knob-and-tube wiring has to be de-energized or replaced by a licensed electrician before cellulose is dense-packed into the affected walls.

Where a permit is required, insulation work in Medway is filed with the Medway Building Department; see the Medway Building Department’s contact, portal and who pulls the permit on permits.llc.

Typical project cost

Eastern Massachusetts insulation pricing runs a bit above the central part of the state. As of recent cycles, attic insulation typically runs $1,500-$4,000, dense-pack wall insulation $2,000-$6,000, and air sealing $300-$1,500; spray foam runs higher. Medway's newer subdivisions often need attic and rim-joist work at the lower end, while the older village homes can require pricier full-wall dense-packing. With Mass Save covering 75-100% of approved work, out-of-pocket on a qualifying job can land near zero.

About Medway homes

Medway is a Norfolk County town of about 13,164 residents across roughly 4,598 housing units. The median home is around 50 years old, a mix of 1970s-80s subdivisions, newer construction along the Franklin line, and a core of older homes near Medway and West Medway villages.

That range means two kinds of insulation work. Mid-century and newer homes usually need attic top-ups, rim-joist sealing, and comfort fixes over garages and bonus rooms. The older village homes more often carry balloon-framed walls and lighter original insulation, where dense-packing the wall cavities makes the biggest difference.

Common questions — Insulation in Medway

Does Mass Save pay for insulation in Medway?
Yes. Medway is served by an investor-owned utility, so after a no-cost Mass Save Home Energy Assessment the program covers 75 to 100 percent of approved insulation and air sealing (no cost for income-eligible households) and finances the rest through the 0 percent HEAT Loan.
My home is in West Medway and may have knob-and-tube. Can I dense-pack the walls?
Not until the wiring is handled. Knob-and-tube must be de-energized or replaced by a licensed electrician before cellulose goes into those cavities. A Mass Save assessment will identify it first.
Could my older Medway attic contain asbestos vermiculite?
Pre-1981 homes sometimes have vermiculite (Zonolite), which can contain asbestos. It must be tested and, if positive, abated before new insulation is installed. The assessment routinely screens for it.
Do I need a permit to insulate my Medway home?
Usually not for insulation itself. Use a contractor with an HIC registration and Mass Save approved status, and note any spray foam must meet state fire-barrier code.
