The Federal Program That Pays to Weatherize Your Home

A drafty house costs money every month, whether the draft comes from thin attic insulation, an old furnace that runs longer than it should, or windows that never quite seal. If your heating and cooling bills have crept higher each year and the house still feels cold in the corners, a federal program may pay to fix the actual problem instead of just covering the bill on top of it.

The Weatherization Assistance Program, run by the U.S. Department of Energy through state and local weatherization agencies, sends a trained crew to seal, insulate, and repair the parts of a home that leak heat and money. It targets income-eligible households, and many states put a retiree living on a fixed income who wants to stay independent in the house they already know near the front of the line.

What the Program Actually Pays For

The Weatherization Assistance Program pays for the work that makes a house use less energy for the long haul, not the bill itself. That means insulation added to the attic, walls, or floor, air sealing around windows, doors, and outlets, and duct sealing so the warm or cool air you're paying for actually reaches the rooms you use instead of leaking into the walls.

Depending on what your home needs and what the state agency finds during an inspection, the program can also repair or replace a failing furnace or heating system, and cover health-and-safety repairs tied directly to the weatherization work itself, like fixing a vent that would otherwise trap exhaust once the house is sealed tighter. Before an inspector ever walks through your house, use the checklist below to note the problems you already know about.

How This Program Is Different From Bill Assistance

People often mix up the Weatherization Assistance Program with the Low Income Home Energy Assistance Program, known as LIHEAP, which helps pay the heating or cooling bill you already owe this month. The two solve different problems. LIHEAP is a payment toward a bill you're already facing, and it doesn't change how much energy the house uses next month or next winter.

The weatherization program works on the house itself, so the improvements keep lowering your bill long after the crew has packed up their tools. Knowing which program fits your situation helps you ask for the right kind of help when you call. Name the part of your energy bill that worries you most, and keep that answer in mind as you go through the eligibility and application steps below.

Who Typically Qualifies

The Weatherization Assistance Program is income-eligible, meaning your household has to fall under a limit that each state sets and adjusts on its own. Many states also give priority to households with an older adult, a person with a disability, or a documented high energy burden, meaning energy costs already eat up an unusually large share of the household's income. Both homeowners and renters can qualify, though renters need their landlord's permission before any crew can start work.

You don't have to guess whether you qualify before you apply. Your state weatherization agency walks you through the income documentation as part of the application, and a home energy audit confirms what work your specific house actually needs. Gather what you can ahead of time so the process moves faster once you're on the phone or filling out the form.

If you own your home in a rural area, you may also qualify for the USDA Section 504 home repair grant, which covers a different set of repairs and has its own income rules.

What Happens During the Home Visit

Once your application moves forward, an energy auditor comes to your house to test for air leaks, check the heating system, and confirm which repairs the program will cover. This visit decides the actual scope of work, so the more clearly you can describe your concerns, the more useful the visit tends to be. Have your notes from the checklist above on hand when the auditor arrives.

The auditor may use a blower door test to measure how much air is escaping, check for combustion safety around gas appliances, and walk the attic, basement, and crawl space if your home has them. Treat the visit as a working conversation rather than an inspection you need to pass. Use the short list below to get ready for it.

How to Apply Through Your State's Agency

You apply for the Weatherization Assistance Program through your state's weatherization agency, not directly through the U.S. Department of Energy. Most states route applications through a network of local Community Action Agencies, the same nonprofit offices that handle other income-based assistance programs in your area. Search the Department of Energy's WAP program page for your state's contact, or call your local Community Action Agency directly and ask about weatherization.

There's generally no cost to your household for approved weatherization work. Use the timeline below to keep the steps in order instead of trying to handle everything in the same week.

Once the crew has been through the attic and around your doors, it's worth revisiting the rest of the house while you're already thinking about safety. Read Aging in Place Home Safety Checklist for Seniors Who Want to Stay Independent for what else to check room by room.
