The Weatherization Assistance Program is designed to reduce the impact of high home energy costs for income eligible residents by implementing energy-efficient measures that may include reducing air infiltration, installing insulation, heating system repair or replacement, and air quality assessment.

Homeowners as well as renters with owner approval may be eligible. After certification of eligibility based on household income and number of household members, each home is assessed by CAASTLC to determine the appropriate services.  Professional, bonded and insured contractors perform the actual services. Each completed job must pass a final inspection for materials and workmanship by CAASTLC. Dwellings are prioritized for services based on winter energy consumption, elderly or disabled household members, and other factors.  If you are interested, please call (314) 863-0015, Option 2. Or you can print and complete the application as instructed below.
