How to Document Water Damage for an Insurance Claim

The single most important factor in a water damage insurance claim is not the loss itself — it is the documentation that proves it. Your insurer needs to see the source of the water, the extent of the damage, the category of water, the scope of work required, and proof that the structure was dried to a verified standard. The Insurance Information Institute provides guidance on documenting losses.

A provider's documentation — moisture maps, thermal images, photos, drying logs, and a written scope — is what supports your claim and the amounts involved. We are a referral service and we do not perform the work, but the providers we connect you with can document the loss for your insurer. See our insurance claims guidance page.

• Photos: Take photos of the water source, the standing water, and every affected room — wide shots and close-ups.
• Video: Walk through the affected area with a phone video, narrating what you see and when it started.
• Receipts: Save receipts for any emergency mitigation you pay for out of pocket (towels, a wet vac, hotel costs if displaced).
• Timeline: Write down the time the damage started, when you noticed it, and what you did in response.
• Communication log: Note the time and date of every call to your insurer, your agent, and any provider.

Do not begin demolition or removal before photographing the damage — your insurer may need to see the original conditions. See our what to do before the provider arrives guide.

• Moisture mapping: Moisture meter readings across affected walls, floors, and ceilings, showing the full extent of saturation.
• Thermal imaging: Infrared images that reveal hidden moisture behind walls and under flooring.
• Water category: Classification of the water as Category 1, 2, or 3 per the IICRC S500 standard, which affects the scope of work.
• Written scope of work: A detailed, line-item estimate for extraction, drying, demolition, and reconstruction.
• Drying logs: Daily moisture readings showing the drying progress and the final verified dry standard.
• Final report: A summary report tying the documentation together for your insurer and adjuster.

Your insurer typically needs: proof of sudden and accidental damage (not gradual or long-term), the source of the water, the category of water, photos of the damage, a scope of work with estimated costs, and proof the structure was dried to a verified standard. They may also send an adjuster to inspect in person.

Coverage depends on your policy terms and your insurer's determination — we cannot guarantee coverage. See our Illinois insurance coverage guide and the Illinois Department of Insurance.

• Starting demolition before photographing the original damage.
• Failing to document the water source or the category of water.
• No moisture readings to prove the structure was actually dried.
• Throwing away damaged materials before the adjuster sees them.
• Waiting too long to report the loss — most policies require prompt notice.
• Not keeping a communication log of insurer and provider calls.
