Weatherization Assistance

Weatherization installs free energy conservation measures and energy-efficient appliances in low-income households in both Arapahoe and Adams Counties. Eligible households will conserve energy and save money on heating and cooling bills, while improving comfort year-round. The National Weatherization Assistance Program has been in place since 1976.


Services may include:

  • Energy audit of the home
  • Energy conservation information
  • Furnace and water heater safety test
  • Furnace replacement, if eligible
  • Insulation in attics, walls and crawl spaces
  • Storm Windows, if eligible
  • Sealing air leaks
  • LED light bulbs

Eligibility for Traditional Weatherization

We can weatherize owner-occupied homes and rentals, including single-family houses, mobile homes and multi-family units up to a four-plex. A home can only receive weatherization services once. All services and materials are provided at no cost to eligible households, and all employees and subcontractors must pass a background check.

Please carefully review the eligibility requirements

Funding for weatherization services is provided by the Colorado Energy Office and the U.S. Department of Energy Denver Regional Office.

Eligibility for Energy Efficiency Home Improvements

For a limited time, special grant funding is available to provide free Energy Efficiency Home Improvements to owner-occupied households (no renters) in Arapahoe County, excluding Aurora households with household incomes at or below 80 percent of adjusted median income.

Please carefully review the eligibility requirements.
