Insulation contractor in Berlin, New Hampshire

What we see in Berlin homes
The typical Berlin home dates from before 1950, which in our experience means balloon framing with empty wall cavities, an attic with a few inches of settled fiberglass or nothing at all, a fieldstone or brick foundation that leaks air at the sill, and the occasional knob-and-tube circuit we have to work around. These houses are the biggest winners under NHSaves: dense-packing the walls and sealing the attic floor routinely cuts heating fuel use by a quarter or more.
About 90% of owner-occupied homes in Berlin 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 Berlin; heating fuel shares are for owner-occupied homes.
NHSaves rebates in Berlin
Most of Berlin is served by Eversource for electricity and Liberty for natural gas. All of them are NHSaves utilities. If you heat with natural gas your Home Energy Performance rebate comes through Liberty; if you heat with anything else it comes through Eversource.
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.
Many Berlin households also qualify for the program’s income-eligible side. Households at or below 60% of the state median income get the work covered in full through NHSaves Home Energy Assistance, and Eversource customers up to the state median income can get an enhanced no-cost package. Tell us roughly what the household earns and we will point you to the right program; nothing is filed without your say-so.

We give you the exact figure in writing after the assessment, and 0% or 2% financing is available for your share.
