Mass Save in HullDepends on your gas service

Hull gets its electricity from Hull Municipal Light Plant, a municipal light plant, not from Eversource, National Grid or Unitil. Mass Save is funded through investor-owned utility bills, so the electric side of the program does not apply in Hull: a home heated with oil, propane or electricity here does not qualify for the Mass Save Home Energy Assessment or the 75 to 100 percent insulation incentive through its electric account.

Gas is the exception. Insulation and air sealing replace nothing, so Mass Save only needs one participating account, and a Hull home with gas service from an investor-owned gas company (National Grid, Eversource, Berkshire Gas, Liberty or Unitil) is a Mass Save gas customer: the free assessment, the 75 to 100 percent insulation incentive and the 0 percent HEAT Loan all apply through the gas account, even if the house heats with oil and only uses gas for hot water. Homes without a gas account should ask Hull Municipal Light Plant about its own weatherization or efficiency rebates, which most Massachusetts light plants offer at a smaller scale.

Insulation in Hull — what to know

Permits in Hull

Insulation and air sealing in Hull generally need no building permit. Mass Save's participating-contractor list applies in Hull only if you enroll through an investor-owned gas account; otherwise hire any HIC-registered, insured installer and check Hull Municipal Light Plant's program requirements. Spray foam must meet state fire and ignition-barrier code, typically a thermal barrier over exposed foam. On Hull's exposed coastal lots, work near a wetland or flood zone can draw conservation review. Older homes with knob-and-tube or asbestos vermiculite need licensed electrical or abatement work first.

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

Typical project cost

Hull sits in the South Shore coastal market, where insulation pricing runs moderate to somewhat higher given access and the age of the housing. 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 costs more per square foot. Whether the Mass Save 75 to 100 percent incentive applies in Hull depends on your gas service: a home with an investor-owned gas account can bring out-of-pocket on approved attic and wall work near zero, while a home without one pays closer to these full figures unless Hull Municipal Light Plant's program offsets part of it.

About Hull homes

Hull is a narrow Plymouth County peninsula town of about 10,116 people across roughly 5,831 housing units, with a median home age near 83 years — among the oldest stock in this batch. Many homes started as compact early-20th-century summer cottages packed tight along the beach, later winterized for year-round living.

That history makes insulation a real need here: thin walls built for July, minimal attic insulation, and exposed coastal sites that take the full brunt of wind off the water. Older homes can have balloon-framed walls, knob-and-tube wiring, and pre-1981 attic vermiculite, so air sealing and wall insulation often come with prerequisite work.

Common questions — Insulation in Hull

Does Mass Save pay for insulation in Hull?
It depends on your gas service. Hull's electricity comes from a municipal light plant, which is outside the Mass Save electric program, but insulation only needs one participating account: a home with a National Grid gas account gets the no-cost assessment and the 75 to 100 percent insulation incentive through it, even if it heats with oil. Homes with no gas account use the light plant's own weatherization rebate.
Does the federal insulation tax credit still apply in Hull?
No — the federal IRS 25C tax credit for insulation expired on December 31, 2025, so insulation work done in 2026 no longer qualifies. The savings now come from the state and utility incentives described above.
My Hull cottage was a summer place — is it worth insulating for winter?
Usually yes. Cottages winterized from seasonal use often have almost no wall or attic insulation, so air sealing and added insulation can sharply cut heating costs in an exposed coastal spot like Hull.
Could my older Hull home have asbestos vermiculite or knob-and-tube?
With a median home age over 80 years, both are possible. Pre-1981 vermiculite should be tested before attic work, and active knob-and-tube must be remediated by a licensed electrician before walls are dense-packed.
