Mass Save in BeverlyEligible

Beverly is in National Grid territory, so homeowners qualify for the full Mass Save program. A no-cost Mass Save Home Energy Assessment is the first step; Mass Save then typically covers 75-100% of approved insulation and air-sealing costs (100% for income-eligible households), plus the 0% Mass Save HEAT Loan up to $25,000 for the homeowner share. In Beverly's older homes the assessment may flag knob-and-tube wiring to clear before dense-packing, and pre-1981 attics that should be checked for vermiculite first.

Insulation in Beverly — what to know

Permits in Beverly

Insulation in Beverly usually needs no standalone building permit, but the contractor should hold a Home Improvement Contractor (HIC) registration, with a Construction Supervisor License (CSL) for structural-adjacent work. Mass Save jobs require a participating contractor. Spray foam must meet Massachusetts fire and ignition-barrier code, with a thermal barrier over exposed foam. In older downtown and coastal homes, knob-and-tube wiring must be remediated by an electrician under an electrical permit before the walls are dense-packed.

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

Typical project cost

On the North Shore, Beverly's insulation costs run near or slightly above the state average. Attic insulation typically runs $1,500-$4,000, dense-pack wall insulation $2,000-$6,000, and air sealing $300-$1,500; spray foam runs higher. Because Beverly is a Mass Save town, the 75-100% incentive can bring out-of-pocket near zero on qualifying work. Home age, wall access, and any knob-and-tube remediation are the biggest drivers of the final cost.

About Beverly homes

Beverly is an Essex County coastal city of about 42,414 residents in roughly 17,656 housing units. The median home is around 68 years old, with a stock that ranges from older homes in downtown and Beverly Cove to postwar neighborhoods in Centerville and North Beverly.

That spread gives the city a varied insulation profile. Many mid-century homes need attic top-ups, dense-pack walls, and air sealing, while the older coastal and downtown housing can have uninsulated balloon-framed walls, plaster-and-lath, and knob-and-tube wiring. Across both, air sealing the attic plane and filling empty wall cavities deliver the clearest comfort and heating-cost gains.

Common questions — Insulation in Beverly

Does Mass Save pay for insulation in Beverly?
Yes. Beverly 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.
My older Beverly Cove home has knob-and-tube. Can I dense-pack?
Not until the wiring is handled. Active knob-and-tube must be remediated or de-energized by an electrician before dense-packing, because live wiring buried in insulation is a fire risk. A Mass Save assessment will identify it.
Do I need a permit to insulate my Beverly home?
Insulation alone usually needs no building permit. Use a Home Improvement Contractor-registered installer; electrical and structural work is permitted separately.
What's the best first insulation project for a mid-century Beverly home?
Air sealing the attic plane and topping up attic insulation usually give the best return on comfort and heating bills. In National Grid-served Beverly, Mass Save typically covers most or all of this work.
Should I worry about vermiculite in my older Beverly attic?
If the home predates 1981 and the attic has loose granular vermiculite (Zonolite), it may contain asbestos and should be tested before insulating. Fiberglass-batt attics are not a concern.
