The Government Will Insulate Your Home for Free. Most People Have Never Heard of This.
The Weatherization Assistance Program (WAP) is a federal program that has been helping low-income households reduce energy costs since 1976. It pays for home energy upgrades — insulation, air sealing, heating system repairs, and more — at no cost to qualifying homeowners.
Approximately 35,000 homes are weatherized each year through this program. But millions more qualify and never apply.
What’s Covered
The program covers a comprehensive energy audit of your home, followed by upgrades that may include:
• Attic, wall, and floor insulation
• Air sealing (caulking, weatherstripping, sealing ductwork)
• Heating and cooling system repairs or replacement
• Water heater insulation or replacement
• Window and door repairs
• Ventilation improvements for health and safety
The average investment per home is approximately $7,669, and households save an average of $372 per year on energy costs after weatherization, according to the Department of Energy.
Who Qualifies
Eligibility is based on household income, typically at or below 200% of the federal poverty level. For 2026, that’s roughly $31,200 for a single person or $42,400 for a household of two. Priority is given to:
• Seniors (60+)
• People with disabilities
• Families with young children
• Households with high energy burden (energy costs as a percentage of income)
Both homeowners and renters can qualify (with landlord approval for renters).
How to Apply
The program is administered locally through community action agencies. To find your local provider, visit energy.gov’s WAP page or call the National Energy Assistance Referral hotline at 1-866-674-6327.
Wait times vary by location — some areas have waiting lists of several months. Apply as early as possible.
