How to Document Water Damage

Finding water where it shouldn't be is stressful, and the instinct is to start mopping right away. But if you might file an insurance claim or ask a landlord to fix it, a few minutes of documentation before cleanup can save you weeks of back-and-forth. Here is what to do, roughly in order.

1. Make sure it's safe first

Water and electricity are a dangerous mix. Before you walk into a wet area:

• Stay out of standing water if outlets, cords or appliances could be in it. If you can reach the breaker panel safely from a dry spot, turn off power to the affected area; if not, call an electrician or your utility.
• Watch for sagging ceilings, which can hold a lot of water.
• Treat floodwater and sewage backups as contaminated. Wear gloves and boots, and keep children and pets away.

OSHA's flood preparedness and response page covers electrical and other hazards during cleanup, and Ready.gov has guidance on what to do after a flood.

2. Stop the water if you can

If the source is inside the house, a burst pipe, a failed supply line or an overflowing appliance, shut off the water. That might be a valve under the sink or toilet, behind the washer, or the main shutoff for the whole house. Knowing where your main shutoff is before you need it is one of the most useful things a homeowner or tenant can learn.

Insurance policies commonly expect you to take reasonable steps to prevent further damage, so stopping the source quickly also helps your claim. If you rent, notify your landlord or property manager right away, especially if the leak comes from another unit or a shared pipe.

3. Photograph and video everything before cleanup

This is the step people skip, and the one that matters most later. Before you move things or start drying:

• Wide shots of each affected room from the doorway, so the scale is clear.
• Close-ups of the source (the burst pipe, the stain on the ceiling) and of damaged materials: floors, baseboards, drywall, cabinets.
• Water level: if there's standing water, photograph it against something with a known height, like a baseboard or a tape measure.
• Damaged belongings: photograph items where they are, then individually. Capture brand names, model and serial numbers where you can.
• A slow video walkthrough, narrating what you see and the date and time.

Your phone's photos include a date and time, which helps establish the timeline. Back them up somewhere other than your phone.

4. Write a simple timeline

Memory gets fuzzy fast. Start a note on your phone or a sheet of paper with:

• When you first noticed the water, and what you saw
• What you think caused it
• Every step you took, with times (shut off valve, moved furniture, called a plumber)
• Everyone you contacted: insurer, landlord, plumber, restoration company. Note the date, time, name and what was said
• Claim numbers and reference numbers as soon as you get them

If you talk to someone by phone, a short follow-up email (“Just confirming what we discussed today…”) creates a written record.

5. Start drying quickly, and keep receipts

Once things are documented, move fast on drying. The EPA's guidance on mold cleanup in your home says it is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth.

• Move wet belongings to a dry area.
• Use fans and a dehumidifier, and open windows if the weather allows.
• For larger losses, a water damage restoration company can bring drying equipment and moisture meters. Ask your insurer whether they want you to use a particular company or get approval first.

Keep every receipt: fans or dehumidifiers you bought, emergency plumber bills, hotel stays if the home isn't livable, and restoration invoices. Many policies cover reasonable emergency costs, but you need the paper trail to show them.

6. Report it the right way

If you own the home

Call your insurance company or file the claim online as soon as you can. Ask what is covered under your policy, what documentation they want, whether an adjuster will visit and whether you should wait before throwing away damaged materials. Flood damage from rising outside water is often handled differently from a burst pipe inside the house, so ask about that directly if it applies to you.

If you rent

Tell your landlord or property manager in writing (email or text works, as long as it's saved), describe the problem and attach a few photos. Keep a copy. Your landlord is usually responsible for repairs to the building itself, while your own belongings are typically a matter for renters insurance if you have it. Tenant rights and repair timelines differ by state and city, so check your local housing authority or tenant resources if repairs stall.

7. Organize everything in one place

By now you may have dozens of photos, receipts, emails and notes. Put them in one folder, paper or digital, with simple sections: photos, timeline, receipts, estimates, and correspondence. When an adjuster or landlord asks for something, you can send it in minutes.

When it's time to fix the damage, get written estimates and compare them carefully. Our guide on comparing contractor estimates and the home repair budget calculator can help you plan the repair and any costs your coverage won't pay.

Preventing the next one

Many water problems give small warnings first: a stain on the ceiling, a musty smell, a slow drip under a sink, a gutter that overflows in every storm. A regular look around catches a lot of them. Our free home maintenance checklist includes monthly leak checks, seasonal gutter cleaning and reminders to protect pipes before freezing weather.
