Insulation in Hull — what to know

Rebates & incentives

Hull is served by the Hull Municipal Light Plant (HMLP), a municipal utility, which means the town is NOT eligible for Mass Save. The 75-100% Mass Save insulation incentives and the 0% HEAT Loan that Eversource and National Grid customers get do not apply here. Instead, homeowners should contact the Hull Municipal Light Plant directly to ask about any insulation, weatherization, or energy-efficiency rebates it offers through its own program.

Permits in Hull

Insulation and air sealing in Hull generally need no building permit. Use a contractor carrying a Massachusetts Home Improvement Contractor (HIC) registration; note that because Hull isn't a Mass Save town, you won't be limited to the Mass Save participating-contractor network. 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.

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. Unlike Eversource and National Grid towns, Hull homeowners can't lean on the Mass Save 75-100% incentive to push out-of-pocket toward zero, so budget for closer to full cost unless the HMLP program offsets 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

Can I get Mass Save insulation rebates in Hull?
No. Hull is served by the Hull Municipal Light Plant, a municipal utility, so it is not part of Mass Save. Contact the Hull Municipal Light Plant directly to ask about its own weatherization or insulation rebates.
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.
