What insulation costs in New Hampshire with NHSaves
The program's own averages for a typical project, what moves the number, and how to get yours in writing.
What a project usually costs
Homeowners ask for a number before the visit, so here is the honest version. The figures below are the program's own averages across New Hampshire Home Energy Performance projects; your house will land above or below them.
| Typical NHSaves project | Amount |
|---|---|
| Total work (air sealing, attic, walls, basement as needed) | about $8,000 |
| Program rebate (100% of air sealing, 75% of insulation, cap $6,000) | about $5,000 to $6,000 |
| Homeowner's share | about $2,800 on average |
| Financing for the share | 0% or 2% loans, $1,000 to $15,000, 2 to 7 years |
Program averages reported by the utilities' program staff. NHSaves® is the energy-efficiency program of New Hampshire's electric and natural gas utilities: Eversource, Liberty, Unitil and the New Hampshire Electric Co-op. Program eligibility requirements and restrictions apply. Rebate amounts are set by the utility program, depend on each home's assessment results, and are subject to change or cancellation while funding is available. Granite Hearth Home Performance is an independent contractor and does not sponsor or operate the NHSaves programs.

What moves the number
- Empty walls. Dense-packing the walls of a pre-1980 cape or colonial is the biggest single line, and the one that changes the house most.
- Attic depth and access. An open attic with 4 inches of old fiberglass is a quick job; a floored, finished or cathedral attic takes more work.
- Basement and crawl space. Rim joist foam is modest; a full crawl-space encapsulation is not.
- The cap. Once the rebate reaches $6,000 the rest of the scope is yours; the program funds air sealing first, then the measures that save the most per dollar.
- Things the program does not fund. Knob-and-tube, vermiculite. We price those separately and never bury them in the program scope.
How to get your number
- Run the qualifier with your ZIP, fuel and square feet.
- Book the assessment. We measure, test and model the house.
- You get the scope, the rebate and your share in writing before anything is scheduled.
Questions about cost
What does a typical NHSaves insulation project cost in New Hampshire?
Across the program, a typical Home Energy Performance project runs about $8,000 in total work, the program pays roughly $5,000 to $6,000 of it, and the homeowner's share averages about $2,800. Your numbers depend on the house: a cape with empty walls costs more than a ranch that only needs attic work, and the rebate is capped at $6,000.
What does attic insulation cost on its own?
An attic air-seal-and-insulate scope in a typical southern New Hampshire home falls in the low thousands before the rebate. Under NHSaves the air sealing is covered in full and the insulation at 75%, so the homeowner's share for an attic-only job is often under $1,000. We quote from the measured attic, never from the phone.
Is the home energy assessment free?
Ask us about the current terms for your utility; they differ by utility and change from year to year, and we will tell you plainly before we book it.
Can I finance my share?
Yes. Each utility offers 0% on-bill financing up to a cap, and partner lenders offer 0% (Eversource) or 2% (Liberty, Unitil, Co-op) loans from $1,000 to $15,000 over 2 to 7 years. The loan is set up before the work starts.
What is not covered by the rebate?
Knob-and-tube wiring and vermiculite removal are not program measures, though they can sometimes be added to the financing. Heat pumps have their own utility rebates with their own amounts.
