What to Do When You Find Water Damage: First Steps in Your Home

When you find water damage, stop the water first. Shut the valve behind the leaking appliance or fixture. If you can’t find it, use the main shutoff to the house. Stay away from anything electrical near the water. Then call a restoration company. Don’t try to suck it all up yourself, and don’t file an insurance claim until you’ve talked it through with someone who does this for a living.

Maybe a supply line let go in the laundry room. Maybe the water heater is weeping, or a toilet ran all night. Either way, your stomach drops. What now? Here’s each step in plain order.

What should you do first when you find water damage?

Find where the water is coming from and stop it. That comes first.

Most of the time the source is obvious once you look: a washing machine hose that split, a dishwasher line, a supply line under a sink. If it’s an appliance, go to the shutoff valves behind or under it and turn them clockwise until the flow stops. If you can’t find those valves, or they’re stuck, shut off the whole house at the main.

Speed matters. A half-inch supply line can put hundreds of gallons inside a wall before anyone gets the main shut off. Every minute it keeps running, more of your house soaks it up. Stop the source faster and you’ll have less secondary damage later, and less to dry out.

Not sure where your shutoff or main is? Lots of people aren’t. Most have never had a reason to look. Call us and we’ll talk you through finding it over the phone while you’re standing there.

Should I turn off the water main?

Turn off the main when you can’t stop the leak at the fixture itself.

The local shutoff valve is the first choice because it only cuts water to that one appliance or sink. Those valves live behind the washer, under the toilet and beneath the vanity. Turn them and the leak usually stops right there.

But if the valve is buried, painted over or broken, or you just can’t find it, don’t stand there fighting it. Go to the main shutoff and kill water to the whole house. It’s usually near where the water line comes into the house, in the garage, or at the meter box out front. Shutting off the whole house is a blunt tool. A stopped leak still beats a perfect one.

One safety note while you’re shutting things off. If water is anywhere near outlets or the panel, or you’re standing in it, treat electricity as a real hazard ⁽²⁾. When in doubt, stay out of the room and wait for help.

Should I remove the water myself?

No. Leave the extraction to us.

We get why people grab the shop vac and the towels. It feels like doing something. But extraction is our part of the job, and you don’t need to do any of it before we arrive. Get the water turned off and the flow stopped. That’s it. That’s the homeowner’s whole job in the first hour.

If you’re thinking about doing the cleanup yourself, our guide to DIY water damage restoration explains where small clean-water spills end and professional drying begins. The water you can see is only a small piece of the problem. The rest wicks into baseboards and drywall, down into the subfloor and up into cabinet bases where a towel never reaches. Mold can start growing on damp materials in as little as 24 to 48 hours ⁽¹⁾. Pull up wet carpet the wrong way and you can spread contamination or hide the moisture that causes the real trouble.

Our crews bring extractors, moisture meters and air movers, and we check where the water actually went. See our emergency water extraction and 24-hour emergency water damage restoration pages for what that looks like.

If the cause was a broken line, our burst pipe cleanup service covers the full dry-out once the plumber caps the leak. We don’t fix the pipe. We handle everything after the plumber.

Should I call my insurance or a restoration company first?

Call the restoration company first. Then bring in your insurance agent.

Your agent is a good resource, and you’ll want them in the loop. But you can call us for everything and we’ll walk you through it one step at a time. Your agent hasn’t been standing in your laundry room.

Here’s the part most people miss. Before you file anything, ask whether you should. A small claim can raise your premium or count against you for years, and sometimes the repair costs less than your deductible. On that first call, one of our main jobs is helping you figure out whether filing makes sense for your situation. We have a process we walk through for exactly that. The Insurance Information Institute notes that whether water damage is covered depends heavily on the cause, so it pays to get the facts straight before you file ⁽³⁾.

If filing turns out to be the right move, our insurance claim help team documents the loss with photos, moisture readings and a line-item estimate and sends it to your adjuster. Your carrier makes the coverage decision. If you want to read up first, we broke down what homeowners insurance actually covers in a separate post.

How quickly do I need to act on water damage?

Right away. Water damage is a clock, not a chore for the weekend.

It’s simple. Wet materials get worse the longer they stay wet. Drywall softens. Wood swells. Mold can set in within the first day or two. How fast you move is the biggest thing deciding whether this ends up a quick dry-out or a tear-out and rebuild. That duty to mitigate falls on you as the homeowner, and moving quickly protects your house and your claim.
