Your house may be cold, drafty, too hot in summer, or costing more than you can pay each month. The weatherization audit is the visit that decides what the program can safely do, what it must skip, and whether a repair problem will stop the job before it starts.
Quick snapshot
- A weatherization audit is a whole-home check of energy use, comfort, and safety.
- The auditor may look at utility bills, heating and cooling systems, attic and wall insulation, air leaks, moisture, wiring, vents, combustion appliances, and health hazards.
- Some homes are approved after the audit. Others are deferred because the home is unsafe or outside program limits.
- Weatherization is local. The DOE application page explains that WAP is administered at the state and local level.
- Do not pay a stranger who promises to get you a government weatherization grant. The USAGov weatherization page warns that ads offering free government repair money are often scams.
Fastest realistic first steps
If you have not applied yet, start with the agency that serves your address. In many places, that is a local Community Action Agency, housing department, tribal housing office, nonprofit weatherization provider, or state energy office. The national program is federal, but the intake rules, waitlists, forms, and appointment timing are local.
- Find the correct local provider. Use your state weatherization page, call 2-1-1, or ask your utility company who handles low-income weatherization in your county.
- Ask if you need a separate LIHEAP application. Some agencies use energy-assistance paperwork to screen for weatherization. The United Way 211 utility page explains that LIHEAP may include bill help, crisis help, weatherization, and energy-related home repairs.
- Gather proof before the audit. The local agency may ask for ID, income, proof of ownership or rent, utility bills, Social Security benefit letters, disability income, unemployment income, or landlord approval.
- Do not start major work without asking first. If you hire your own contractor before approval, the program may not reimburse you.
Phone script: finding the right agency
Hello, I live in [city/county/ZIP code]. I need help with weatherization because my energy bills are high and my home is uncomfortable. Which agency handles Weatherization Assistance Program applications for my address? Do I apply through weatherization, LIHEAP, or both?
Handle danger before waiting for the audit
Weatherization is not an emergency repair program. If you smell gas, see sparks, have a serious carbon monoxide alarm, have active sewage backup, or have a heating system that was red-tagged by a utility or code official, treat that as a safety issue now. Leave the home if there may be carbon monoxide or gas danger and call emergency services or the utility emergency line.
Gas and oil furnaces can produce carbon monoxide, which the CDC furnace safety page describes as invisible, odorless, and able to kill without warning. If anyone has headaches, dizziness, vomiting, weakness, confusion, chest pain, or feels better after leaving the house, do not wait for a weatherization appointment.
What weatherization auditors usually check
The auditor is trying to answer three questions: where is the home wasting energy, what work would save the most under program rules, and can the work be done safely? A professional home energy assessment may include a room-by-room inspection and tools such as blower doors, infrared cameras, gas leak detectors, carbon monoxide detectors, moisture meters, and smoke pencils, according to the DOE assessment guide.
| Area checked | What the auditor is looking for | Why it matters |
|---|---|---|
| Utility bills | High use, fuel type, shutoff risk, seasonal patterns, account name, and past usage. | Programs often use bills to judge energy burden and to choose work that can lower use. |
| Heating and cooling | Age, condition, venting, filters, ducts, thermostats, fuel leaks, unsafe equipment, and whether the system works. | Unsafe or broken systems may need repair, replacement, or deferral depending on local rules and funding. |
| Air leaks | Gaps around attics, basements, crawl spaces, plumbing holes, wiring holes, doors, windows, and ducts. | Air sealing is often one of the most useful weatherization measures, but it must be balanced with ventilation and combustion safety. |
| Insulation | Missing, thin, wet, damaged, or unsafe insulation in attics, walls, floors, knee walls, and manufactured-home bellies. | Insulation can help comfort and bills, but wet insulation, roof leaks, pests, or unsafe wiring may stop the job. |
| Moisture and mold | Roof leaks, plumbing leaks, crawl space water, condensation, musty smells, visible mold, and damaged drywall or flooring. | Moisture can ruin new work and create health risks. Severe moisture is a common deferral reason. |
| Electrical safety | Overloaded panels, exposed wiring, unsafe outlets, knob-and-tube wiring, missing covers, or wiring in areas where insulation may be added. | Weatherization crews cannot bury unsafe wiring under insulation or work around serious electrical hazards. |
| Combustion safety | Furnaces, boilers, water heaters, fireplaces, gas stoves, flues, draft, gas leaks, and carbon monoxide risk. | Tightening a home can affect air flow. The auditor must avoid making a combustion problem worse. |
| Lead, asbestos, and hazards | Pre-1978 paint, asbestos-like materials, vermiculite insulation, damaged flooring, pests, sewage, hoarding, or unsafe access. | Some hazards require special work practices, extra funding, or a referral before weatherization can continue. |
How to prepare for the audit
You do not need to make the home perfect. In fact, hiding problems can hurt your case because the auditor needs to see what is really going on. Your goal is to make the visit safe, clear, and complete.
Gather documents
Local agencies set their own paperwork rules, but many ask for some mix of these items:
- Photo ID for adults in the home.
- Proof of income for each household member, such as pay stubs, Social Security letters, pension letters, unemployment, child support, or benefit award letters.
- Recent electric, gas, propane, oil, wood, or other fuel bills.
- Proof that you own the home, pay the mortgage, rent the home, or live in the unit.
- Landlord permission if you rent. Weatherization work often changes the building, so the owner usually must approve.
- Proof of public benefits, if the agency uses benefits to help screen eligibility.
- Photos, repair notices, red tags, insurance letters, code notices, or contractor estimates if the home has repair hazards.
Make access possible
The auditor may need to reach the attic hatch, crawl space, basement, furnace, water heater, electric panel, main rooms, and exterior walls. Move items if you can do so safely. Do not climb, lift, or crawl if it could hurt you. Tell the agency before the visit.
Write down the worst comfort problems
Write down rooms that are always cold or hot, places where pipes freeze, rooms with musty smells, heavy window condensation, and times when bills spike. Show photos of leaks or ice if they do not happen during the visit.
Tip: Ask the auditor to explain what they are testing as they go. You are allowed to ask plain questions like, “Will this problem stop the job?” and “What should I fix first if I am deferred?”
Tools the auditor may use
Not every home gets every test. The tools depend on the program, home type, weather, safety, staff training, and whether the home is ready for testing. Common tools include:
- Blower door: A temporary fan placed in a doorway to measure air leakage and help find gaps.
- Infrared camera: A camera that can help show temperature differences that may point to missing insulation or air movement.
- Gas leak detector: A tool used around gas lines, appliances, or fittings.
- Carbon monoxide meter: A tool used to check combustion appliances and indoor safety concerns.
- Moisture meter: A tool used to check wet materials, hidden dampness, or possible leak areas.
- Pressure testing: Testing that may be used around ducts, combustion appliances, or rooms with exhaust fans.
If the auditor does not run a blower door test, it does not always mean they skipped their job. It may be unsafe to depressurize a home with certain combustion problems, severe mold, loose asbestos-like materials, unsafe wiring, active leaks, open sewage, or other hazards.
What work may be approved after the audit
Weatherization is meant to reduce energy use and improve health and safety. It is not the same as a general remodeling grant. The NASCSP WAP overview describes WAP as a program that reduces heating and cooling costs for low-income families, especially elderly people, people with disabilities, and children, by improving energy efficiency while protecting health and safety.
Depending on local rules, approved work may include air sealing, insulation, duct sealing, heating or cooling system work, water heater measures, ventilation, basic health and safety repairs, LED lighting, refrigerator replacement, or minor repairs needed to protect energy work.
Work that is often limited or not covered
- Full roof replacement just because the roof is old.
- Cosmetic remodeling, new cabinets, flooring upgrades, or room additions.
- Major structural rehabilitation.
- Large mold remediation when the moisture source is not fixed.
- Major plumbing, sewer, electrical, or foundation work unless a local deferral-repair fund can help.
- New windows just because they are drafty, unless they pass local program rules.
This is why the audit can feel strict. The auditor may agree that a repair is real but still say WAP cannot pay for it unless it is allowed, cost-justified, safe, and tied to the weatherization job.
Why some homes are deferred before repairs
A deferral means the program is delaying weatherization until a problem is corrected. It is not always a denial forever. It usually means the home is not safe or ready for the weatherization work that would otherwise be done.
The NASCSP deferral guide lists common reasons, including unsafe structure or mechanical systems, sewage or sanitary hazards, condemned homes, red-tagged equipment, severe moisture, high carbon monoxide, and unsafe or threatening conditions for workers. Local agencies must follow their own state plan, health and safety plan, and funding rules.
| Problem found | Why it may stop weatherization | What to ask next |
|---|---|---|
| Active roof leak | New insulation could get wet and fail. The leak may also hide mold or structural damage. | Ask if small leak repair is allowed, or if there is a weatherization readiness or home repair referral. |
| Severe mold or moisture | Crews may not be able to work safely, and sealing the home could make moisture worse. | Ask what moisture source must be fixed and whether photos or a contractor letter will reopen the file. |
| Unsafe electrical wiring | Insulation and air sealing can cover wires or change heat conditions around wiring. | Ask if the agency has a minor electrical allowance or a referral to a repair program. |
| Red-tagged furnace or water heater | Unsafe combustion equipment can create fire, gas, or carbon monoxide danger. | Ask whether the unit can be repaired under weatherization, LIHEAP crisis, utility help, or another heating program. |
| Asbestos-like or vermiculite material | Disturbing it can create worker and occupant hazards. | Ask what testing or abatement documentation is needed before weatherization can continue. |
| Unsafe access or heavy clutter | Workers may not be able to reach equipment, exits, attic hatches, crawl spaces, or panels safely. | Ask exactly what areas must be cleared and whether disability, aging, or social service help is available. |
Some states have special funds to fix deferral problems. Virginia deferral manual covers issues such as leaking roofs, minor structural issues, mold, moisture damage, electrical repairs, and plumbing repairs. Minnesota’s updated pre-weatherization policy lists repairs such as moisture mitigation, structural repairs, plumbing leaks, electrical repairs, pest work, mobile home skirting, and dryer vent repairs. These examples do not mean your state has the same fund, cap, or rules.
Phone script: after a deferral
Hello, my weatherization file was deferred. Can you please tell me the exact deferral reason in writing, what condition must be fixed, whether there is a weatherization readiness fund or partner repair program, and what proof you need to reopen my file?
What happens after the audit
After the visit, the agency usually creates a work scope. It may need supervisor review, bids, approvals, landlord signatures, utility coordination, or funding checks before any crew is sent.
Ask for the next step in plain language. You want to know whether you are approved, waitlisted, deferred, missing paperwork, waiting for contractor scheduling, or waiting for a supervisor review. If the agency gives you a deferral notice, save it. It can help you ask other programs for the exact repair you need.
If you are approved
- Ask what work is approved and what is not.
- Ask whether the work will be done by agency crews or contractors.
- Ask if you need to be home during work days.
- Ask how pets, oxygen equipment, medical devices, mobility needs, or language access should be handled.
- Ask who to call if a contractor arrives without notice, asks for money, or changes the work scope.
If you are delayed or waitlisted
- Ask whether your application is complete.
- Ask whether your household has priority because of age, disability, children, high energy use, or high energy burden.
- Ask how often you should update income, phone number, address, and utility shutoff status.
- Ask whether LIHEAP, utility hardship funds, or 2-1-1 can help while you wait.
Special situations auditors pay attention to
Renters
Renters may be eligible, but the owner usually has to approve work. Ask what form the landlord must sign and whether any tenant-side help is available if the owner refuses.
Manufactured homes
Manufactured homes have different audit needs. The auditor may look at belly board condition, skirting, duct leakage, roof leaks, water lines, floors, and safe under-home access.
Older homes
Homes built before 1978 may involve lead-safe work rules if painted surfaces will be disturbed. The EPA RRP program says paid work that disturbs painted surfaces in pre-1978 homes and child-occupied facilities must generally be done by certified firms using lead-safe work practices. Do not sand or scrape old paint to get ready for the audit.
Mold, leaks, and dampness
The EPA mold guide says the key to mold control is moisture control, and water-damaged areas should be dried within 24 to 48 hours when possible. If you have active leaks, tell the agency. New insulation or air sealing can fail if the water problem is not fixed first.
Common mistakes that slow down weatherization
- Missing the appointment. Call ahead if you must reschedule. No-shows can push you back.
- Not reporting a dangerous condition. Tell the agency about gas smell, red tags, sewage, severe mold, unsafe floors, or violent animals before the visit.
- Hiding rooms or blocking access. The auditor may not be able to approve work they cannot inspect.
- Throwing away paperwork. Keep deferral notices, work scopes, income approvals, landlord forms, and contractor cards.
- Paying for work first. Many programs will not reimburse work that was not approved in advance.
- Assuming windows are the main fix. In many homes, air sealing, insulation, duct work, ventilation, or heating safety may matter more than window replacement.
Backup options if weatherization cannot do everything
If the audit finds real repair needs that WAP cannot pay for, ask for a referral in writing. A clear deferral notice can help another agency understand the problem. Depending on where you live, these may be worth checking:
- LIHEAP or energy crisis help. Use 2-1-1 or your state LIHEAP office to ask about heating, cooling, shutoff, reconnection, and crisis rules.
- Utility programs. Some utilities offer income-based audits, arrearage plans, hardship funds, appliance rebates, or safety checks.
- City or county rehab programs. Local repair programs may help with roof, plumbing, electrical, or accessibility issues.
- USDA rural repair help. Very-low-income rural homeowners may be able to ask USDA Rural Development about repair loans or grants if the property and household qualify.
- HUD-approved housing counseling. If you are considering a loan, lien, HELOC, reverse mortgage, or contractor financing, a HUD housing counselor can help you slow down and compare safer options.
- Rebates and incentives. The ENERGY STAR savings tool can help you look for current incentives by product and location, but always check income rules and deadlines before buying.
- Tax credits for past work. The IRS energy credit page says the Energy Efficient Home Improvement Credit applied to qualifying improvements made through December 31, 2025. Do not assume 2026 work qualifies without checking current IRS rules.
Phone script: calling the utility
Hello, I am applying for weatherization and my audit may be delayed. Do you offer income-based energy audits, arrearage help, shutoff protection, payment plans, appliance rebates, furnace safety checks, or referrals to the local weatherization agency?
Scam and financing cautions
Real weatherization programs do not cold-call you and promise a personal grant if you pay a processing fee. The FTC grant scam warning says scammers may contact people out of the blue, ask for personal or banking information, or demand fees by cash, gift card, wire transfer, or cryptocurrency. Do not pay those fees.
Also be careful with contractors who use the weatherization audit to pressure you into a loan. The FTC contractor warning says warning signs include door-to-door pitches, pressure for an immediate decision, requests for full payment up front, cash-only demands, and contractors who tell you to borrow from a lender they know.
Before you sign any repair loan, ask: What is the total cost? Is there a lien? Can the payment change? What happens if I miss a payment? Is the contractor licensed and insured? Did I get more than one estimate? Could a no-cost or low-cost program help first?
Phone script: checking before a loan
Hello, I am thinking about financing repairs after a weatherization deferral. Can you help me review the loan terms, lien risk, contractor documents, and whether there are local repair programs I should try before I sign?
What to say during the audit
You do not have to know building science words. Use plain facts. Tell the auditor:
- Which rooms are too cold, too hot, damp, or hard to heat.
- Whether anyone has asthma, uses oxygen, relies on powered medical equipment, or has mobility limits that affect scheduling or safety.
- Whether you use space heaters, window air conditioners, fans, wood heat, propane, oil, or other backup heat.
- Whether there have been leaks, frozen pipes, high bills, shutoff notices, pest issues, or red tags.
- Whether you are a renter, heir-property occupant, manufactured-home owner, tribal housing resident, or living in a home with tangled title.
Ask for copies of forms you sign, who will call next, and whether the work list can change after review. A clear record helps if you later need to appeal or ask another program for help.
FAQs
Is a weatherization audit the same as a home inspection?
No. A home inspection is usually a broad condition report, often used in real estate. A weatherization audit focuses on energy use, comfort, health, safety, and which measures the program may approve. It may notice repair problems, but it is not a full structural, code, or insurance inspection.
Will the auditor replace my windows?
Do not assume that. Many weatherization programs focus first on measures that save more energy for the cost, such as air sealing, insulation, duct work, ventilation, or heating safety. Window repair or replacement depends on local rules, the audit, funding, and whether the measure is allowed.
Can renters get weatherization?
Yes, renters may be eligible, but the landlord or owner usually must approve work because crews may change the building. Ask the local agency what landlord form is required and whether there are tenant protections tied to the work.
What does it mean if my home is deferred?
A deferral means the agency is delaying weatherization because a problem must be fixed first. Common causes include unsafe wiring, severe moisture, sewage hazards, red-tagged equipment, structural problems, or unsafe working conditions. Ask for the deferral reason in writing and what proof is needed to reopen the file.
Do I have to pay for the audit?
For an approved Weatherization Assistance Program application, the audit is normally part of the program process. Paid private energy audits are different. If someone demands an upfront processing fee for a government weatherization grant, call your local agency directly before paying anything.
