Mass Save in GeorgetownDepends on your gas service

Georgetown gets its electricity from Georgetown Municipal Light Department, 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 Georgetown: 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 Georgetown 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 Georgetown Municipal Light Department about its own weatherization or efficiency rebates, which most Massachusetts light plants offer at a smaller scale.

Insulation in Georgetown — what to know

Permits in Georgetown

Insulation and air sealing in Georgetown usually require no building permit. Mass Save's participating-contractor list applies in Georgetown only if you enroll through an investor-owned gas account; otherwise hire any HIC-registered, insured installer and check Georgetown Municipal Light Department's program requirements. Spray foam must meet state fire and ignition-barrier code, normally a thermal barrier over exposed foam. Georgetown's permitting runs through the town building department, and the historic town center can draw review for exterior changes, though interior insulation rarely does. Older wiring or asbestos vermiculite requires licensed electrical or abatement work first.

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

Typical project cost

Georgetown sits in the North Shore / Essex County market, where insulation pricing runs near eastern-Massachusetts rates. 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 Georgetown 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 Georgetown Municipal Light Department's program offsets part of it.

About Georgetown homes

Georgetown is an Essex County town of about 8,455 people across roughly 3,226 housing units, with a median home age near 53 years. The stock mixes later-20th-century colonials and capes with an older center-village core dating to the town's earlier shoe-and-farming history, so insulation work ranges from attic top-ups to wall retrofits in the older homes.

Those older village and farmhouse homes can carry balloon-framed walls, knob-and-tube wiring, and pre-1981 attic vermiculite, which set the order of work before any cavity gets insulated. Newer homes on the edges are mostly about attic R-value and air sealing.

Common questions — Insulation in Georgetown

Does Mass Save pay for insulation in Georgetown?
It depends on your gas service. Georgetown'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 Georgetown?
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.
Could my older Georgetown home have knob-and-tube wiring?
It's possible in the town's older village and farmhouse stock. Active knob-and-tube must be remediated or de-energized before walls are dense-packed, and a licensed electrician handles that first.
What insulation work helps most on a newer Georgetown home?
For later-built stock, the biggest gains usually come from topping up attic insulation and air sealing the attic floor and rim joist. An energy audit can measure your levels and set priorities.
