How to File a Flood Insurance Claim, Step by Step

Updated October 2026

Flood claims run on deadlines and paperwork. Doing the steps in order — and documenting before anything is thrown out — is the difference between a full payment and an argument.

1. Report the claim right away

Call your insurance agent or the insurer that issued the policy — for NFIP policies that is usually a private company selling under the program, not FEMA itself. Have your policy number, a phone number where you can be reached, and the address of the damaged building. If you cannot find your insurer, the NFIP Help Center can look it up.

2. Document everything before cleanup

Photograph and video every room, the outside of the building, and the high-water line on the walls.
Photograph damaged items with serial and model numbers visible for appliances and electronics.
Keep small samples of carpet, flooring, drywall and fabrics so the adjuster can see the materials.
List damaged belongings with what you paid and roughly when. Receipts, bank records and old photos help.

3. Prevent more damage

Get water out and start drying the building quickly — mold that grows because the owner did not act is not covered. Throw out spoiled food and items that are a health hazard, after photographing them. Keep every receipt for pumps, fans, dehumidifiers and cleanup services; reasonable costs are part of the claim.

4. Meet the adjuster

The insurer assigns an adjuster to inspect the damage and prepare an estimate. Walk through the building with them, point out everything you documented, and ask how building and contents will be valued. Ask whether you can receive an advance payment — NFIP insurers can pay part of the claim before the final estimate so you can start repairs.

5. Sign and file the proof of loss

The proof of loss is your sworn statement of the amount you are claiming. For NFIP policies it is due within 60 days of the flood. Adjusters often prepare it for you from their estimate; read it carefully before signing. If more damage turns up later, you can file a supplemental claim with another proof of loss.

6. Know the numbers before you argue

In Florida, Illinois, Louisiana, New Jersey, New York, North Carolina and Texas, the median paid flood claim since 2015 was $52,000, and 20% of claims closed without any payment — usually because the damage was under the deductible or was not covered. Payouts are capped by your coverage limits, contents are paid at depreciated value, and most basement finishes and belongings are excluded. See the average flood claim by state and zone.

7. If the claim is denied or underpaid

Ask for the decision and the reasons in writing.
Send additional documentation — contractor estimates, photos, receipts — and file a supplemental claim for anything missed.
For NFIP policies, appeal to FEMA within 60 days of the written denial. The appeal is free and you do not need a lawyer.
Lawsuits over NFIP claims must be filed in federal court within one year of the written denial.
For large losses, a licensed public adjuster or an attorney can help — public adjusters usually take a percentage of the payment.

Also check for help beyond the policy

If FEMA declares a disaster in your county, register for disaster assistance too — it can cover some costs flood insurance does not, such as temporary housing. If your home is declared substantially damaged, the Increased Cost of Compliance part of your policy can pay up to $30,000 toward elevating or flood-proofing it.

Common questions

How long do I have to file a flood insurance claim?

Report the loss to your insurer as soon as you can. For NFIP policies, the signed proof of loss is due within 60 days of the flood unless FEMA extends the deadline, which it often does after large disasters.

How long does a flood insurance claim take?

Adjusters usually contact policyholders within a few days of the claim being reported, though after a major hurricane it can take longer. Simple claims settle in weeks; large or disputed ones can take months.

Can I start cleaning up before the adjuster comes?

Yes, and you should — the policy expects you to prevent further damage and mold. Photograph everything first, keep samples of flooring and wallboard, and keep receipts for cleanup costs.

What if I disagree with the payment?

Ask the insurer for a written explanation, send any additional documentation, and file a supplemental claim if damage was missed. For NFIP policies you can then appeal to FEMA within 60 days of the written denial, or sue within one year of it.
