What to Do in the First Hour After Water Damage

By Washington Water Damage Pros · Published 2026-09-24

Step 1: Stop the Water

Everything else waits until the supply is closed. Find the main shut-off for the house. In most Washington homes it is near the water heater, in a utility closet, in the crawl space or at the curb, and knowing where it is beforehand saves ten minutes when it matters. Turn it clockwise until it stops, then open the lowest faucet in the house to drain pressure out of the lines.

For an appliance leak, close the valve behind or under the unit instead of the main. Washing machines, dishwashers, water heaters and refrigerators with ice makers each have their own shut-off, and those valves are also the ones that commonly fail. If water is spraying from a pinhole in a copper line, wrapping the section with a towel and tape slows it down long enough to shut the valve, nothing more.

If the water is coming from outside

During a river flood, a storm-drain backup or a king tide, you cannot stop the source. Do not try. Move valuables and documents up, move boxes off the floor, and get out of a basement or garden-level room once the water is more than ankle deep, because that much water can hide a live circuit or a sunken hole in the floor.

Step 2: Make the Room Safe to Enter

Water and electricity are the pair that hurt people. Cut power to the affected rooms at the breaker panel if you can reach the panel by walking on dry ground. If the panel itself is wet, do not touch it; call an electrician and tell the dispatcher.

• Keep children and pets out of the area, and put a towel or a chair at the doorway as a reminder.
• Do not walk through standing water that covers outlets, extension cords or appliance cords.
• Stay out of any room where the ceiling is bulging, sagging, or dripping near a light fixture.
• Wear boots and rubber gloves. Assume any water that came from a fixture other than a supply line is contaminated.
• Open windows only if it is dry outside. In a Washington winter, opening a window adds humidity and slows the dry-out.

Step 3: Photograph Everything Before You Touch It

Your claim is a record, not a memory. Before you move a single item, take wide photos of each room, then closer photos of the water line on the baseboard, the source if it is visible, the damaged furniture, and the serial-number plate on the failed appliance. A thirty-second video that pans across the room and narrates what you see is worth more than a dozen still images.

Record the time you found the water and the time you shut it off. Adjusters ask when the loss began, and a specific answer is much stronger than a guess.

Step 4: Move What Can Be Saved, Block What Cannot

Prioritize in this order: documents and irreplaceable items, electronics, upholstered furniture, then rugs and textiles. Wood furniture left on a wet carpet will wick water up its legs and stain within hours, so slide aluminum foil or plastic wrap under the feet, or move the piece out of the room entirely. Take cushions off sofas and stand them on edge so air can reach both sides.

Anything you lift should be photographed in its new position only after the original position is documented. Do not pull up carpet yourself unless a technician tells you to: cutting it the wrong way can make it unsalvageable and complicate the claim.

Step 5: Start Mild Extraction, Not Demolition

Towels and a mop handle the shallow edges around the wet area, and that is as far as most homeowners should go. Water that has reached the padding has already soaked the subfloor beneath it, and no amount of blotting reaches that layer. Cutting drywall, prying baseboards or opening a floor is the kind of work that should be documented and done by a crew, because it is also the work adjusters pay for.

Step 6: Call and Describe It Precisely

When you call (888) 217-5329, have four facts ready: what the water came from, how deep it is, how long it has been there, and what kind of flooring it is sitting on. Those four answers determine whether the job is classified as clean water or contaminated water and whether the crew arrives with extraction equipment, containment or both.

You can read more about how each type of loss is handled on our water damage restoration and emergency water extraction pages, and if the water came from a drain or a toilet, start with sewage cleanup instead.

What Happens After the First Hour

Once a crew is on site, the order of work is fixed: find and confirm the source, map how far the water traveled, extract standing water, remove what cannot be saved, then dry the structure to a measured standard with daily readings. Repairs come last, after the moisture readings say every material is dry. Homeowners in Seattle, Tacoma and Spokane see the same sequence; only the cause of the water changes from one side of the state to the other.

Two habits make the whole process easier. First, keep the failed part, whether it is a supply line, a valve or a pump, so the adjuster can inspect it. Second, take the drying log and photo record when the job ends and store it with your policy documents. That file is what you will reach for during the next storm, a resale inspection or a dispute over a claim.
