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

You walk into the laundry room and the floor is wet. A supply line let go, the water heater is weeping, or a toilet ran all night. Your stomach drops. So what now?

Here is the short version, then the details.

What should you do first when you find water damage?

Find where the water is coming from and stop it. That is the very first move, before anything else.

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. When it is an appliance, go to the shutoff valves behind or under it and turn them clockwise until the flow stops. If you cannot find those valves, or they are stuck, shut the water off to the whole house at the main.

Speed matters here. A half-inch supply line can put hundreds of gallons inside a wall before anyone gets the main shut off. Every minute the water keeps running is more of your home soaking it up. The faster you stop the source, the less secondary damage you deal with later, and the less there is to dry out.

Not sure where your shutoff valve or main is? You are not alone. Most people have never had a reason to look. That is fine. Give us a call and we will talk you through finding it over the phone while you are standing there.

Should I turn off the water main?

Turn off the main when you cannot stop the leak at the fixture itself.

The local shutoff valve is always the first choice because it only cuts water to that one appliance or sink. Behind the washing machine, under the toilet, beneath the vanity, that is where those valves live. Turn them and the leak usually stops on the spot.

But if the valve is buried, painted over, broken, or you just cannot find it, do not stand there fighting it. Go to the main shutoff and kill water to the whole house. It is usually near where the water line enters the home, in the garage, or at the meter box out front. Whole-house is a blunt tool, but a stopped leak beats a perfect one.

One safety note that goes with shutting things off: if water is anywhere near outlets, the panel, or you are 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 productive. But real water extraction is our part of the job, and there is no need for you to do any of it before we arrive. The best thing you can do is get the water turned off and stop the flow. That is it. That is the homeowner’s job in the first hour.

Here is the problem with DIY drying. The water you can see on the surface is a small piece of it. The rest wicks into baseboards, drywall, subfloor, and 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 carry truck-mount extractors, moisture meters, and commercial air movers, and we know 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 after the plumber caps the leak. We handle the part that comes after the plumber.

Should I call my insurance or a restoration company first?

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

Your agent is a great resource, and you will want them in the loop. But the honest answer is you should just call us for everything so we can guide you through the steps one at a time. We have done this thousands of times. Your agent has not been standing in your laundry room.

Here is the piece most people miss. Before you file anything, there is a real question of whether you even should. A small claim can raise your premium or count against you for years, and sometimes the repair costs less than your deductible. One of our main jobs on that first call is helping you figure out whether filing a claim 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 getting the facts straight before you file matters ⁽³⁾.

If it turns out filing is the right move, our insurance claim help team documents the loss and works directly with your adjuster. And 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?

Immediately. Water damage is a clock, not a to-do list item for the weekend.

The reason is simple. Wet materials keep getting worse the longer they stay wet. Drywall softens, wood swells, and mold sets in within that first day or two. Acting fast is the single biggest thing that decides whether this is a quick dry-out or a tear-out and rebuild. That duty to mitigate is on you as the homeowner, and moving quickly protects both your house and your claim.

Want to understand what you are actually dealing with? Our pillar guide on the types of water damage breaks down clean, gray, and black water and why the category changes everything about the response. And if you are in the Valley right now, our Henderson water damage restoration team is the fastest way to get eyes on it.

So, the whole thing in one breath: stop the water, skip the DIY extraction, and call us before you call anyone else. We will handle the rest and help you decide the smart next step.
