Federal Window Replacement Program for Seniors: WAP, USDA 504, LIHEAP

There is no single federal window replacement program for seniors, but three federal programs will pay for or heavily subsidize new windows if you qualify: the Department of Energy’s Weatherization Assistance Program, the USDA Section 504 Home Repair program for rural homeowners, and the Low Income Home Energy Assistance Program. Which one fits depends on your income, whether you own or rent, and where you live.

The Three Programs That Pay for Windows

Weatherization Assistance Program

The Department of Energy’s Weatherization Assistance Program is the most direct route to free window replacement. Federal law specifically lists storm windows, multi-glazed windows, and heat-reflective window materials as eligible weatherization measures.¹ Money flows from DOE to state agencies and then to local community action agencies that do the work.² You pay nothing. The agency inspects your home, picks the contractor, and covers materials and labor.

The statute that created the program singles out elderly individuals as “particularly vulnerable” and tells agencies to prioritize their applications alongside households with disabilities and families with children.³ That priority matters because local agencies often have waiting lists. Being a senior moves you closer to the front, but it does not guarantee immediate service.

USDA Section 504 Home Repair

If you live in a rural area, the USDA Section 504 program offers grants of up to $10,000 and loans of up to $40,000 to fix health and safety hazards, and old windows that no longer open, lock, or insulate typically qualify.⁴ The $10,000 grant cap is a lifetime limit, not a per-project amount. Loans carry a fixed 1% interest rate with terms up to 20 years.⁵ A senior on Social Security who needs a full-house window replacement can combine a grant with a low-interest loan to cover a project that would otherwise run into the tens of thousands.

LIHEAP

LIHEAP mostly helps with heating and cooling bills, but it also funds weatherization and small energy-related repairs.⁶ Federal law caps LIHEAP weatherization spending at 15% of a state’s allotment, or 25% with a waiver.⁷ Because of that cap, LIHEAP window work tends to be smaller: a couple of critical windows rather than the whole house. States and tribes run LIHEAP their own way, so what counts as an eligible repair in one state may not in another. Find your local office by calling the National Energy Assistance Referral line at 1-866-674-6327.

Who Qualifies

Weatherization Assistance Program

You qualify for WAP if your household income is at or below 200% of the federal poverty level. For 2026, that is roughly $31,920 for a single person or about $43,280 for a two-person household.⁸ States can use 60% of state median income instead if that number is higher.⁹ Receiving Supplemental Security Income makes you automatically eligible. Homeowners and renters both qualify, though renters need written permission from the landlord before any work starts.

USDA Section 504

Section 504 is stricter. Your household income has to fall below the “very low income” limit for your county, generally 50% of area median income. To receive a grant rather than a loan, you must also be at least 62 years old and unable to get affordable credit from a conventional lender.¹⁰ The program is limited to homeowners who occupy the property as their primary residence. Renters cannot apply. Check whether your county is classified as rural, and look up the income limits, on the USDA Rural Development website.

LIHEAP

LIHEAP income rules vary by state but generally require income at or below 150% of the federal poverty level or 60% of state median income, whichever is greater.⁷ There is no age cutoff, but many states prioritize elderly households the way WAP does.

How to Apply

The documents look similar across all three programs. Expect to hand over:

Proof of income for the prior year, including Social Security benefit statements, pension records, and bank statements. Your most recent tax return if you filed one.⁹
Social Security numbers and dates of birth for everyone in the household.
Proof of residence: a deed or mortgage statement if you own, a lease if you rent.
Twelve months of utility bills showing your energy usage.
Property tax records for USDA Section 504, to confirm ownership and that taxes are current.

WAP applications go through your local community action agency; DOE keeps an online directory, or you can call your state energy office. USDA Section 504 applications go through your regional USDA Rural Development office, online or by mail. Use the exact figures from your official income documents. Rounding or estimating can slow the application down or trigger a request for extra verification.

What Happens After You Apply

Once the agency accepts your application as complete, it schedules a home assessment. For WAP, a technician performs an energy audit to identify where your home is losing the most heat and which upgrades will deliver the biggest savings. New windows may or may not be the top recommendation; insulation and air sealing sometimes win out. For USDA Section 504, an inspector looks more broadly at health and safety hazards.

The audit becomes the work order, listing what gets done, what materials are used, and the total cost. You will get either an award letter or a placement on the waiting list. Wait times vary by locality. Some agencies move within weeks; others have backlogs of several months. The agency selects licensed contractors and oversees installation. You do not pick your own contractor or manage the project.

The USDA Grant Has a Three-Year Recapture

A Section 504 grant is not entirely free of strings. If you sell your home within three years of getting the grant, you have to repay the full amount.⁴ A senior who accepts a $10,000 grant and then moves into assisted living two years later would owe the full amount at closing. If a move within three years is realistic, the 1% loan may fit better, because loan proceeds do not carry the recapture obligation.

The Federal Window Tax Credit Has Expired

Through the end of 2025, homeowners who paid out of pocket for energy-efficient windows could claim the Section 25C Energy Efficient Home Improvement Credit, worth 30% of the cost up to $600 a year for windows.¹¹ The credit expired on December 31, 2025, and is not available for windows installed in 2026 or later. It would not have applied to windows you received free through a federal program anyway, but if you are paying out of pocket to supplement what a program covers, there is no federal tax credit currently available to offset those costs.

Watch for Window Replacement Scams

The federal government itself warns that websites and ads promising “free money from the government” for home repairs are often scams.¹² Seniors are a favorite target. A few patterns show up over and over:

Someone knocks on your door claiming to work in the neighborhood and says your windows need replacing. Real contractors and federal programs do not operate this way.
A contractor demands a large upfront payment. Federal programs pay contractors directly, so you should never be asked to write a check for program-funded work.
A caller claims to represent a government weatherization program. Real program contacts come through your local community action agency, not cold calls or door-to-door visits.
High-pressure sales tactics and claims about “limited-time government funding” are classic fraud signals.
