Mass Save in EdgartownEligible

Edgartown is in Eversource territory, so homeowners qualify for the full Mass Save program. Start with the no-cost Mass Save Home Energy Assessment, which finds your main heat-loss points and checks for knob-and-tube wiring or, in pre-1981 attics, vermiculite that may contain asbestos. Mass Save then typically covers 75-100% of approved insulation and air-sealing costs, with 100% for income-eligible households, plus the 0% Mass Save HEAT Loan up to $25,000 for the homeowner share.

Insulation in Edgartown — what to know

Permits in Edgartown

Insulation in Edgartown generally needs no standalone building permit, but the contractor should hold a Home Improvement Contractor (HIC) registration, with a Construction Supervisor License (CSL) for related structural work. Mass Save incentives require participating, approved contractors. Spray foam must meet Massachusetts fire and ignition-barrier code. Edgartown's historic district means exterior changes to its antique homes need review, and those older houses may carry pre-1981 vermiculite or knob-and-tube needing licensed handling before insulating.

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

Typical project cost

Edgartown is on Martha's Vineyard, where insulation pricing runs above mainland Massachusetts because materials and crews typically travel by ferry. 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, with spray foam higher; island logistics push toward the upper end. As an Eversource town it's Mass Save eligible, so the 75-100% incentive can still bring out-of-pocket on approved attic and wall work down to near zero.

About Edgartown homes

Edgartown is a Martha's Vineyard town in Dukes County with about 5,159 year-round residents but roughly 5,176 housing units — essentially as many homes as people, a hallmark of the island's seasonal market. The median construction age is near 43 years.

For insulation, Edgartown spans whaling-era captains' houses in the historic district, a large stock of seasonal homes built for summer use, and newer year-round construction. The seasonal homes often have thin attic insulation and uninsulated walls, while the antique village homes can carry balloon framing and knob-and-tube wiring. Attic and air-sealing work leads as homes shift to year-round use.

Common questions — Insulation in Edgartown

Does Mass Save pay for insulation in Edgartown?
Yes. Edgartown 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.
Can I insulate a historic Edgartown captain's house?
Yes, though exterior changes in the historic district need review. Interior attic and air-sealing work is usually the focus, and dense-packing balloon-framed walls is possible once any knob-and-tube wiring is cleared.
Why does insulation cost more in Edgartown?
Materials and crews generally come over by ferry, which adds time and cost.
Do I need a permit to insulate my Edgartown home?
Insulation itself usually needs no building permit, but exterior changes in the historic district require review. Use an HIC-registered, Mass Save participating contractor and confirm any spray foam meets fire-barrier code.
