Home Insulation Program
Tired of chilly drafts in winter or hot spots in summer?
Insulation is your first line of defense. It seals up hidden gaps in attics, walls, and floors—keeping unwanted air out and comfort in. That means lower energy bills and a cozier home year-round. And with our trusted contractors, installation and paperwork are taken care of for you.
Our Home Insulation Program can help.
Here’s how it works:
- Complete our short interest form or reach out to a trusted installer listed below.
- One of our trusted insulation installers will measure and inspect your home’s existing attic, wall, duct, and floor insulation.
- If your home could benefit from better insulation, you’ll receive an estimate for the total cost to make the upgrade.
- Estimates for homes that meet program eligibility requirements will include money-saving rebates. There’s no obligation—move forward only if the estimate works for you.
- Your installer will handle all the paperwork for you, keeping the entire process easy.

What if a contractor wants to join the program?
At this time, we are not accepting new contractors for the Home Insulation Program. If enrollment opportunities become available in the future, we will provide updated information on how to apply.
To qualify for our Home Insulation Program, you must:
- Be an existing Avista residential customer
- Be applying for your primary residence in an existing single family, duplex, triplex or fourplex home
- New construction does not qualify
- Meet pre-existing and post-projects insulation levels (R-values)
- Washington customers: Heat your home with Avista electricity or natural gas via electric or natural gas furnace, natural gas boiler, electric cadet (wall heater), radiant heating, baseboards or heat pump
- Idaho customers: Heat your home with Avista electricity via electric furnace, electric cadet (wall heater), radiant heating, baseboards or heat pump
This program does not require income qualifications. All eligible customers can apply.
The estimate you receive from your contractor will tell you what the R-value of your existing insulation is, as well as the new R-value, should additional insulation be suggested.
