Weatherization Programs

What is weatherization?

Weatherization is adding insulation, sealing cracks, and making other changes that reduce heat loss, save you money on heating bills and make your home or apartment healthier. The federal government and Washington State offer weatherization programs, which Commerce runs, for qualified low-income households.

Weatherization Benefits

Saving $270 a year due to weatherization


This month we celebrate 40 years of housing improvements through weatherization. Between 2016 and 2017 over 2,200 low-income homes and apartments throughout Washington were insulated, had air-leaking cracks sealed, pipes and ducts wrapped, ventilation improved and safety repairs completed. These measures combined saved our clients an average 20% on their energy bills. The health benefits of weatherization can be equally important. Click here for the whole story.

What has the program done over the years and where it is headed? Watch the video below for the story.

Can I get my home weatherized?

Commerce doesn’t weatherize houses directly. We contract with local agencies in your city or county that weatherize qualified low-income homes and apartments.

To see if you qualify for weatherization assistance, call a local agency near you on the Weatherization Agency List.

How are these programs funded?

Commerce receives funding from Washington State and several federal government programs to help pay for low-income weatherization work.

- State of Washington

          • Utility companies that sell gas and electric heat also contribute matching funds for qualified low-income households. There funds match the Washington state dollars through the Matchmaker Program.

Weatherization Data

All local agencies providing services in the Washington State Weatherization Program report their results through the Weatherization Information Data System (WIDS). (WIDS is security-protected and is only accessible by local agencies and Commerce staff.)
