Looking for an insulation company near you in Washington?

Most of the insulation work is paid for by your utility's program.
What we see in Washington homes
The typical Washington home dates from after 1980, so it has some insulation already. What it usually lacks is air sealing: recessed lights, attic hatches, duct chases and top plates leak warm air into the attic, and the attic itself is often below today's R-49 to R-60 standard. Newer homes also tend to have ductwork and electric or propane heat, which makes them strong candidates for a cold-climate heat pump.
About 71% of owner-occupied homes in Washington 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. Around 24% heat primarily with wood or pellets. A tighter house means fewer cords a winter, and a heat pump can take the shoulder seasons so the stove runs only when it is truly cold.
Housing figures: U.S. Census Bureau, American Community Survey 2020 to 2024 five-year estimates for Washington; heating fuel shares are for owner-occupied homes.
NHSaves rebates in Washington
Most of Washington is served by Eversource 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 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 Washington 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.
