Mass Save in West TisburyEligible

West Tisbury is in Eversource territory, an investor-owned utility, so homeowners are Mass Save eligible. Insulation and air sealing are the program's flagship weatherization measures: the no-cost Mass Save Home Energy Assessment comes first, then Mass Save typically covers 75–100% of approved attic, wall, and air-sealing costs, with 100% for income-eligible households.

The 0% Mass Save HEAT Loan covers the homeowner share up to $25,000. Island energy costs run high, which makes weatherization especially valuable here. Note that contractor availability and ferry-related logistics can lengthen scheduling on the Vineyard.

Insulation in West Tisbury — what to know

Permits in West Tisbury

Insulation in West Tisbury generally needs no standalone building permit, but the contractor should hold a Home Improvement Contractor (HIC) registration, and related structural work requires a Construction Supervisor License (CSL). Mass Save incentives require a participating or approved contractor. Spray foam must meet the state fire and ignition-barrier code. West Tisbury's town bylaws and the Martha's Vineyard Commission can add review for exterior or structural changes, though interior insulation work typically does not trigger that. Coastal moisture also makes proper vapor control important in any island insulation job.

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

Typical project cost

Island pricing runs higher than the mainland because materials, crews, and equipment often arrive by ferry. As of recent cycles, attic insulation that runs $1,500–$4,000 on the mainland can sit toward the upper end here, dense-pack wall insulation $2,000–$6,000, and air sealing $300–$1,500; spray foam runs higher still. Because West Tisbury is a Mass Save town, the 75–100% incentive offsets much of that, bringing out-of-pocket on approved attic and air-sealing work near zero with the HEAT Loan for the balance.

About West Tisbury homes

West Tisbury sits up-island on Martha's Vineyard in Dukes County, with about 2,941 year-round residents but roughly 2,465 housing units — a telling gap that reflects the heavy share of seasonal and second homes. Its median home dates to around 1984, so the stock is newer than the mainland average: shingled capes, contemporary builds, and converted summer cottages.

For insulation, the island climate brings damp, salt-laden coastal air, so moisture management matters as much as R-value. Common work is topping up attic insulation, sealing crawl spaces against ground moisture, and insulating the many seasonal cottages being converted to year-round use. Pre-1981 vermiculite is less common in this newer stock but still worth checking in older up-island farmhouses.

Common questions — Insulation in West Tisbury

Does Mass Save pay for insulation in West Tisbury?
Yes. West 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 seasonal Vineyard cottage to year-round. What insulation does it need?
Conversions usually need attic and wall insulation plus crawl-space sealing for the damp island climate. A Mass Save assessment will scope it, and the program covers most of the approved cost.
Does island salt air affect what insulation I should use?
It affects moisture management more than R-value. On the Vineyard, proper vapor control and crawl-space sealing matter, so a contractor familiar with coastal builds is worth seeking out.
Will scheduling take longer because West Tisbury is on Martha's Vineyard?
It can. Crews and materials often come by ferry, so plan for somewhat longer lead times than on the mainland and confirm the contractor is Mass Save participating to keep the incentives intact.
