Mass Save in PeruEligible

Peru is served by Eversource, so homeowners qualify for Mass Save. The starting point is a no-cost Home Energy Assessment that scopes the house and flags knob-and-tube wiring or pre-1981 vermiculite needing attention before insulating. Mass Save then covers 75-100% of approved insulation and air-sealing costs, with 100% for income-eligible households, plus a 0% HEAT Loan up to $25,000 for the remaining share.

Insulation in Peru — what to know

Permits in Peru

Insulation in Peru rarely requires a building permit, but the contractor should hold a Home Improvement Contractor (HIC) registration, and a Construction Supervisor License (CSL) covers structural work. Mass Save incentives require a participating or approved installer. Spray foam must meet Massachusetts fire and ignition-barrier code, generally with a thermal barrier. In homes built before 1981, vermiculite attic insulation should be tested for asbestos before work, and active knob-and-tube wiring must be remediated or de-energized before walls are dense-packed.

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

Typical project cost

Berkshire hilltown pricing runs near statewide ranges, with a travel premium given Peru's elevation and remote setting. 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, with spray foam higher. Because Peru is a Mass Save town, the 75-100% incentive can bring out-of-pocket cost near zero after an approved assessment, an advantage a municipal-utility town does not share.

About Peru homes

Peru is one of the highest-elevation towns in Massachusetts, a Berkshire County hilltown of about 670 residents and roughly 364 housing units, with a median construction age near 47 years. Its perch on the spine of the Berkshires means a long, cold winter and plenty of wind exposure.

That climate puts a premium on a tight building envelope. Homes here run from older center and farmhouse-era houses with balloon framing to mid-century and later builds needing attic top-up and rim-joist sealing. Most Peru homes heat with oil, propane, or wood, so air sealing and insulation directly cut delivered-fuel use through the heating season.

Common questions — Insulation in Peru

Does Mass Save pay for insulation in Peru?
Yes. Peru 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.
It gets very cold up here. How much attic insulation should I add?
In a high, cold town like Peru, aim for the upper end of code R-values in the attic and pair it with thorough air sealing. The Mass Save assessment sets targets for your home and uses a blower-door test to find leaks.
Could there be asbestos in my old attic insulation?
If your Peru home predates 1981, loose-fill vermiculite attic insulation may contain asbestos and should be tested before insulating. Removal is handled by a licensed abatement contractor.
Do I need a permit to insulate my Peru home?
No separate building permit is usually required for insulation, though your contractor should carry HIC registration. Spray foam must meet fire-code covering requirements.
