Mass Save in TisburyEligible

Tisbury is in Eversource territory, so homeowners qualify for Mass Save. Begin with a no-cost Mass Save Home Energy Assessment; Mass Save then typically covers 75–100% of approved insulation and air-sealing costs, with 100% for income-eligible households. The 0% Mass Save HEAT Loan (up to $25,000) finances the homeowner's share interest-free — useful on the Vineyard, where labor and materials carry a ferry premium.

On older island homes the assessment often surfaces knob-and-tube wiring that needs remediation before dense-packing, or pre-1981 vermiculite to be tested.

Insulation in Tisbury — what to know

Permits in Tisbury

Insulation generally needs no standalone building permit in Tisbury, but use a contractor with a valid Massachusetts Home Improvement Contractor (HIC) registration, and route Mass Save jobs through a participating, approved contractor. Knob-and-tube wiring must be addressed by a licensed electrician before dense-pack cellulose goes in, and spray foam must meet state fire- and ignition-barrier code. Island logistics matter: contractors often batch Vineyard work around ferry schedules, so plan lead time. Permits for any related structural work go through the Tisbury building department.

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

Typical project cost

Insulation costs on Martha's Vineyard run above mainland rates because labor, materials, and equipment all cross on the ferry. As of recent cycles, attic insulation that might be $1,500–$4,000 on the mainland often lands higher here; dense-pack wall insulation runs roughly $2,000–$6,000-plus, air sealing $300–$1,500, and spray foam higher still. The strong offset is that, as an Eversource Mass Save town, Tisbury homeowners can have the 75–100% incentive cut out-of-pocket toward zero on approved measures. Vermiculite or knob-and-tube remediation adds cost where needed.

About Tisbury homes

Tisbury — the Vineyard Haven side of Martha's Vineyard — is a Dukes County town of 4,809 year-round residents across about 3,126 housing units, with a median construction age near 47 years. The housing-unit count well above the population reflects the island's heavy seasonal-home mix, and many of those houses were built for summer use, not winter performance.

That history shows up in the insulation work here: under-insulated walls and attics on older summer cottages, drafty crawl spaces and rim joists, and homes near the harbor exposed to salt air and wind. Owners converting seasonal places to year-round comfort make up a big share of local jobs, alongside attic top-ups and air sealing on the town's older year-round homes.

Common questions — Insulation in Tisbury

Does Mass Save pay for insulation in Tisbury?
Yes. Tisbury 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.
I'm converting a summer cottage to year-round — where should I start?
Begin with a Mass Save Home Energy Assessment. Seasonal Vineyard homes are often under-insulated everywhere, so air sealing plus attic and wall insulation usually deliver the biggest comfort and bill gains.
Could my older Tisbury home have vermiculite or knob-and-tube?
If it predates 1981, vermiculite is possible and should be tested; knob-and-tube turns up in older island homes too. Both are commonly flagged by the Mass Save assessment and must be addressed before dense-packing.
Does insulation work need a permit in Tisbury?
Insulation alone usually doesn't, but related structural work does, filed through the Tisbury building department. Use an HIC-registered, Mass Save participating contractor to keep the rebate intact.
