How to file a water damage insurance claim, step by step

What to do in the first hours after water damage

The first job is safety, then stopping the water. Shut off the main water valve, and keep away from wet outlets, cords or appliances. If water has reached the electrical panel or you are standing in water, do not touch the panel. Leave and call the utility or an electrician. Our water damage emergency guide covers this in more detail.

Once it is safe, document before you clean. Take wide shots of each room and close-ups of the source, the waterline on walls, damaged flooring and belongings. Short videos with narration work well. If the cause is a failed part, such as a split hose, save it.

Then start drying. EPA says it is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. The sample ISO HO-3 policy requires you to protect the property from further damage, make reasonable and necessary repairs to do that, and keep an accurate record of the cost. Emergency drying is usually a protective step. A full rebuild is not, so hold off on permanent repairs until the insurer has seen the damage or agreed in writing.

How and when to notify your insurer

The ISO sample HO-3 lists “prompt notice to us or our agent” as the first duty after a loss. It does not define prompt in days, but delay gives the insurer room to argue that it lost the chance to inspect. Report as soon as you have stopped the water and taken photos. Most insurers take claims by phone, app or online portal. Our insurance claims hub collects related guides.

When you report, give the facts you know: the date you found the water, the source, the rooms affected, and whether you have started drying. Avoid guessing about how long a leak lasted. Write down the claim number and the name of everyone you speak with.

In Florida, section 627.70132 of the Florida Statutes (2025) sets an outer limit. A new or reopened claim is barred unless notice is given within one year after the date of loss. A supplemental claim, for additional damage from the same event that the insurer already adjusted, must be noticed within 18 months. Those are maximums. Your policy may ask for faster notice.

A claim timeline: who does what, and when

This table pulls together the deadlines we could verify from primary sources. It is not complete for every state. Your policy and your state’s law control.

Florida’s insurer deadlines can pause in some cases, such as during mediation or if you do not provide requested information within 10 days, according to section 627.70131.

What documentation an adjuster will ask for

The ISO sample HO-3 lists what you may need to provide. It asks for an inventory of damaged personal property showing the quantity, description, actual cash value and amount of loss, with bills and receipts attached. It also says that, as often as the insurer reasonably requires, you must show the damaged property, provide records and documents it requests, and submit to questions under oath.

Build your file as you go. Useful items include the photos and video from day one, the failed part, the plumber’s invoice naming the cause, moisture readings from the drying company, and receipts for anything you paid. If you had to leave the home, keep hotel and meal receipts for any additional living expenses claim.

Under section 627.70131, a Florida adjuster who inspects must give you their name and state adjuster license number. Write it down. It matters later if you need to file a complaint. Our guide to water mitigation vs restoration explains the drying records a contractor should give you.

Your duty to mitigate, and how it affects payment

The duty to mitigate means taking reasonable steps to stop damage from getting worse. In the ISO sample HO-3, it appears as the duty to protect the property from further damage. The form also says the insurer will pay the reasonable cost you incur for necessary measures taken solely to protect covered property.

In practice, mitigation covers things like stopping the leak, extracting water, running fans and dehumidifiers, removing soaked carpet pad, and covering a roof opening. It does not usually mean rebuilding. Keep invoices, and photograph damaged materials before they are thrown away.

The ISO form says the insurer has no duty to provide coverage if your failure to perform these duties is prejudicial to it. Mold is the most common result of slow mitigation. It can push part of the loss under a smaller mold sublimit. Our mold coverage guide explains how that cap works.

What a proof of loss is and how to complete it

A proof of loss is a signed, sworn statement of the amount you are claiming. The ISO sample HO-3 asks for it within 60 days after the insurer requests it. It typically includes the time and cause of loss, your interest in the property, other insurance, the claimed amounts, and supporting documents such as estimates and the inventory.

NFIP flood claims follow a different clock. FEMA’s fact sheet says flood claimants should submit a signed proof of loss within 60 days after the date of loss, with a building damage estimate and a contents inventory. If you have both a flood claim and a homeowners claim, track each deadline separately.

Fill it in carefully. Only claim what you can support, because the form is sworn. If you are unsure of an amount, ask the insurer in writing how to handle items still being priced, and keep a copy of everything you send.

Contractors, assignment of benefits and Florida’s 2023 change

Restoration companies sometimes ask homeowners to sign an assignment of benefits, which hands the insurance claim, or part of it, to the contractor. In Florida, section 627.7152(13) says a policyholder may not assign post-loss benefits under a residential or commercial property policy issued on or after January 1, 2023. Such an attempt is “void, invalid, and unenforceable.” Policies issued earlier fall under older rules.

Even where assignment is allowed, read every form a contractor gives you before signing. Ask whether it is a work authorization, a direction to pay, or an assignment. Our page on restoration scams and red flags lists warning signs.

If the claim stalls or the estimate looks low, you have options. A licensed public adjuster can handle the claim for a fee. If the insurer denies part of the claim, see what to do when a claim is denied.
