You walk downstairs and there’s water where water shouldn’t be — a wet spot spreading across the ceiling, a puddle by the washing machine, a musty smell that wasn’t there yesterday. What you do in the next ten minutes matters more than most homeowners realize, and I say that as someone who works water damage claims for a living.
I’m a licensed property claims adjuster in New Jersey. I walk into homes after the damage is done and reconstruct what happened from what’s left. The difference between a smooth claim and a painful one almost always comes down to what the homeowner did — or didn’t do — in the first few minutes. Here’s the order that actually matters.
1. Make it safe (60 seconds)
Water and electricity are the immediate danger, not the drywall. If there’s standing water anywhere near outlets, appliances, or your breaker panel, don’t wade in — kill the power to that area from a dry spot first. Look up before you walk in: a sagging, bulging ceiling is holding water and can come down without warning. If the water smells like sewage or came in from outside (floodwater), treat it as contaminated — don’t touch it with bare hands, and keep kids and pets out of the area entirely.
Adjusters notice safety handling because it shows up in the file. “Homeowner shut power and stayed out of the affected area” reads a lot better than a secondary injury or a bigger mess from someone wading through gray water.
2. Stop the source (2 minutes)
Every minute water keeps flowing, your damage — and your claim — gets bigger. This is the single highest-leverage thing you can do:
- Burst pipe or leaking supply line: turn off the main water shutoff to the house. Know where yours is before this day comes — it’s usually in the basement near the front wall, in a utility closet, or outside by the meter.
- Appliance leak (washer, dishwasher, fridge line): shut the valve behind the appliance. Every one of these has its own shutoff — if you don’t know where yours are, go look today, not during an emergency.
- Roof leak during a storm: you can’t fix a roof in the rain. Contain it — buckets, towels — and move to step 3.
- Water coming in from outside (flooding): you can’t stop this. Skip to documentation. Sandbags and barriers go up before the storm, not during it.
If you can stop the source safely, do it before you do anything else. An adjuster can tell the difference between a 20-minute leak and a 6-hour leak, and so can your deductible math — the longer it runs, the more material gets saturated, and saturated material gets torn out, not dried.
3. Document everything before you touch anything (3 minutes)
This is the step homeowners skip, and it’s the one that costs them the most. Photograph and video the damage exactly as you found it — before you move furniture, before you start mopping, before you pull up the rug. Your adjuster needs to see the extent of the damage as discovered, not after cleanup.
What to capture:
- Wide shots of each affected room, then close-ups of every damaged surface
- The source, if visible (the burst pipe, the failed hose, the water line on the wall showing how high it got)
- Damaged belongings where they sit — don’t move them yet
- A quick video walkthrough with you narrating what you see and when you found it
Phone photos are fine. What matters is that they’re timestamped and taken before anything is disturbed. I can’t tell you how many claims get harder because the homeowner cleaned up first and the only evidence of the original damage is their memory. Memories don’t photograph well.
4. Protect what’s undamaged (2 minutes)
Now move valuables, electronics, rugs, and furniture out of the water’s path — but photograph them first (see step 3). If you can’t move something heavy, get it up on blocks or foil-wrapped feet and throw a tarp over it. Pull back area rugs. Open the windows if the weather allows.
This is also mitigation, and your insurance policy requires it — nearly every homeowner policy has a “duty to mitigate” clause, meaning you’re expected to take reasonable steps to prevent further damage. Doing it visibly and early strengthens your position if any part of the claim gets questioned later.
5. Call your insurer — with a script (2 minutes)
Now make the call. Have your policy number ready, and keep it factual and short:
“Hi, I’m reporting a water damage loss at [address]. I discovered it at [time] today. The source was [burst pipe / appliance leak / roof leak / unknown — still investigating]. I’ve shut off the water and documented the damage with photos. I’d like to open a claim and get a claim number.”
That’s it. Don’t speculate about cause, don’t guess at dollar amounts, don’t say “I think it might have been leaking for a while” — that one sentence has complicated more claims than I can count. Stick to what you know. Get the claim number, ask what their next steps are, and write down the name of the person you spoke with.
Then grab the free checklist below — it’s the one-page version of this article you can keep on your phone or tape inside the cabinet under your sink, so you’re not trying to remember any of this while standing in water.
What NOT to do (the claim-killers I see every month)
- Don’t throw anything away yet. That ruined carpet, the swollen baseboards, the dead drywall — your adjuster needs to see it. Bag small items, but keep them until the adjuster has been through.
- Don’t start permanent repairs. Emergency mitigation (drying, tarping) is expected. Ripping out and rebuilding before the adjuster documents the loss is how coverage disputes start.
- Don’t wait to call. Waiting days to report “because it didn’t look that bad” is the most common self-inflicted wound in water claims. Mold starts in 24–48 hours, and late reporting gives the carrier room to argue the damage grew because of delay.
The gear worth having before this happens
Most water damage I see would have been smaller if the homeowner had caught it earlier. Three inexpensive things earn their keep: a water leak detector under sinks, behind the washing machine, and by the water heater (they scream when they get wet — some send phone alerts); a pinless moisture meter so you can check whether a wall is actually dry or just looks dry; and a wet/dry vacuum for the first response before the pros arrive. None of these are exciting purchases. All of them are cheaper than a deductible.
