Insulation contractor in Alton, New Hampshire

What we see in Alton homes
The typical Alton home was built between 1950 and 1980, which usually means R-11 fiberglass batts in the walls, a thin layer of batts on the attic floor, no air sealing anywhere, and a rim joist that was never insulated. Ranches, split-levels and garrison colonials from these decades are the bread and butter of our NHSaves work: air seal and top up the attic, foam the rim joist, and the house feels like a different place.
About 86% of owner-occupied homes in Alton heat with oil or propane, the most expensive fuels in New England per unit of heat. That is why air sealing and insulation pay back so quickly here, and why a cold-climate heat pump is often the next step: it can carry most of the season at a fraction of the cost of delivered fuel.
Housing figures: U.S. Census Bureau, American Community Survey 2020 to 2024 five-year estimates for Alton; heating fuel shares are for owner-occupied homes.
NHSaves rebates in Alton
Most of Alton is served by the NH Electric Co-op for electricity and none for natural gas. All of them are NHSaves utilities. If you heat with natural gas your Home Energy Performance rebate comes through none; if you heat with anything else it comes through the NH Electric Co-op. Parts of town are served by another electric utility (Eversource); either way the program applies, and we confirm your utility from your bill.
On most Home Energy Performance projects the program pays 100% of air sealing and 75% of insulation, up to $6,000 per home, and your share can go on a 0% or 2% program loan. We assess the house, model it, file with the utility and take the rebate off the invoice. How the program works.
