How to Document Basement Water Damage for Insurance

Document basement water damage insurance claims need is a record made at the time, because a claim made weeks later depends on what was written down and photographed when the water was still there. An insurer will ask when the water appeared, where it came from, what it reached, and what was done, and a homeowner who has that record ready can answer clearly. A homeowner who has no record must rely on memory, and memory fades faster than a photograph.

Basements are uncommon across most of California, and they exist mainly in older homes and some hillside areas, so this guidance applies to a smaller group of homes. For those homes, though, a good record is worth making, because it costs nothing and it can matter a great deal. The [basement water damage restoration](/basement-water-damage-restoration/) page describes the restoration service in general terms.

Photograph from a safe place

Photograph the water from a safe, dry place, and never enter a flooded basement to take a photograph. Take a wide shot that shows the room and the water level, and then take closer shots of where the water seems to come from, of the walls and floors it has reached, and of any belongings it has touched. A photograph that shows the height of the water against a wall is more useful than one that shows only the floor.

Take the photographs as soon as it is safe to do so, and take them again as the water is removed, so that the record shows the room before, during, and after the cleanup. Keep the photographs together with the notes, and keep a copy somewhere safe.

Note the time and the cause

Note the time you found the water, the date, and the weather, and note whether the water followed rain or appeared on a dry day. Note where the water seemed to come from, whether it is still rising, and how deep it looks. Those notes are the first thing an insurer will ask about, and a clear note made at the time is worth more than a memory made weeks later.

Do not guess the cause in your notes. Write what you saw, not what you think caused it, because the cause is a matter for a professional looking at the home in person. A note that says what happened is useful; a note that claims a cause can mislead.

List what was damaged

List what was damaged, room by room and item by item, and note where each item was and what the water reached. A list made at the time is more complete than one made from memory, and it helps both the cleanup company and the insurer understand the extent of the damage. Note the age and the condition of each item in general terms, and keep any receipts you have for the items that were damaged.

Do not throw damaged items away before the insurer has had a chance to see them, unless they are a health risk or the insurer has told you to do so. Keep the list with the photographs, so that the record is complete.

Keep receipts and records

Keep every receipt for the work that follows: the cleanup, the drying, the repairs, and any temporary measures. Keep a record of every call you make, including the date, the time, and the name of the person you spoke to. A claim is easier to make when the paper trail is complete, and a paper trail made at the time is easier to trust than one assembled later.

No coverage promise is made here, because whether a claim is covered depends on the policy and the cause, and only the insurer can say. The receipts and the records are for the conversation with the insurer, and they should be kept whether or not a claim is made.

Tell the insurer promptly

Tell the insurer promptly, after the safety steps and after the water has been dealt with, or as soon as it is safe to do so. Ask what the insurer needs from you, and keep a record of the conversation. An insurer may want to send someone to look at the room, and that visit is easier to arrange when the water is still there or the record is fresh.

Do not delay the call, because a delay can make the claim harder to make. The insurance blog on this site describes insurance in general terms only, and it makes no coverage promise.

What not to write in the record

Do not write a cause you have not been told by a professional, do not write a figure for the damage before it has been assessed, and do not write anything you cannot support with a photograph or a note made at the time. A record that sticks to what was seen, when it was seen, and what was done is a strong record, and a record that guesses is a weak one.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Basement Water Damage Restoration page explains what that service covers, the Basement Flooding Cleanup page covers a related part of the job, and the services hub lists every service in one place.

While you wait, do not enter a flooded basement and do not touch switches, plugs or appliances in standing water. Floodwater is not safe water — keep pets and children clear of it.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after heavy rain.
