What to Do in the First Hour After Water Damage

Published September 24, 2026 · Updated September 24, 2026 · Virginia Water Damage Pros

Minute One: Stop the Source

Everything else is secondary to stopping the flow. If water is spraying or running, the supply has to close. In most Virginia homes the main shut-off is either at the meter near the street, in a crawlspace or basement at the point where the line enters, or on an exterior wall. Find yours this week, before you need it, and make sure the handle turns. Gate valves that have not been operated in fifteen years seize, and that is a discovery nobody wants to make at 2 a.m.

Fixture-level shut-offs handle the smaller emergencies. Toilets have an oval valve at the wall behind the bowl. Sinks and vanities have angle stops underneath. Washing machines have hot and cold valves where the hoses connect, and those hoses are one of the most common failure points in any home. Water heaters have a valve on the cold inlet pipe above the tank.

If the water is coming from a storm, a sewer backup or an appliance that has already emptied, there is nothing to shut off. Move to the next step and get the water contained instead.

Minute Five: Deal With Electricity and Slip Hazards

Water and live wiring do not mix. If the wet area contains outlets, extension cords, power strips or an appliance that is still plugged in, kill the circuit at the panel before you walk through standing water. If the panel itself is in the flooded space, or you cannot reach it without stepping in water, do not go near it — that is a call for the utility or an electrician, and it is also a reason to get a professional crew moving immediately.

Watch for the ordinary hazards too. Wet tile, vinyl and hardwood are slippery, and a fall on a stair landing is a worse day than the leak. Wear shoes with grip rather than socks, and keep children and pets out of the area until the water is gone.

Minute Ten: Document Before You Touch Anything

The instinct is to start dragging furniture out of the water. Resist it for five minutes and document instead. Insurance adjusters rely on what you capture in the first minutes, when the scene is untouched: the water line on the wall, the source of the leak, the height the water reached, and the extent of the damage as it actually happened.

• Photograph each affected room from two corners, then a close shot of the water line and the leaking fixture
• Shoot a short video walking through the space and describing what you see out loud, including timestamps you mention
• Photograph the failed component — the split pipe, the ruptured hose, the cracked supply line — before you remove it
• Do not throw away damaged material until the adjuster has seen it or you have been told it can go
• Note the date and time you discovered the water and the time you shut it off

Minute Twenty: Limit the Spread

Now you can move things. Priority order is simple: anything porous, anything electrical, and anything valuable.

Start with electronics and anything plugged in, but only after the circuit is off. Move furniture legs onto aluminum foil or plastic blocks — the goal is to get wood off wet carpet before stain wicks into the finish. Roll up area rugs and get them off the wet floor, because a rug sitting on wet padding will transfer dye into both. Move cardboard boxes and paper records, which wick water fast and are impossible to dry once saturated.

Leave the structure alone. Prying up baseboards, cutting wet drywall or pulling carpet loose before the cause is identified creates more work and can remove material that would have dried fine in place. A crew can measure whether a wall cavity is wet in under a minute; you cannot.

Minute Thirty: Get Air and Dehumidification Moving

Household fans do not dry a wet structure, but they do slow the damage while you wait. Set them to blow across the wet surface rather than into the wall. If the weather allows and the outdoor humidity is lower than the indoor humidity — which in a Virginia summer is often not the case — crack the windows. Run the air conditioning if it is working, because the evaporator coil pulls moisture out of the air as a side effect of cooling.

If you own a dehumidifier, put it in the wet room, close the doors and let it run. Empty the reservoir as it fills. In a humid July or August, that unit is doing more good than any number of box fans.

Do not run a shop vacuum on carpet that is soaked, do not aim a heater at wet drywall, and do not use a household vacuum on standing water. All three turn a restoration job into a replacement job.

Minute Forty: Make the Call

By now you know what broke, how much space is wet, and whether the water was clean or contaminated. That is exactly what a dispatcher needs. Call emergency water extraction for standing water, or full water damage restoration when the water has already soaked into walls and floors.

Two situations should always get a call rather than a mop: water that reached a wall cavity or subfloor, and water that came from a drain, toilet, septic system or storm. The first feeds mold inside a space you cannot reach. The second is contaminated and requires disinfection, not just drying. If the backup came through a floor drain, see sewage cleanup.

What Not to Do

• Do not walk through standing water in a basement until the panel and outlets are confirmed off
• Do not lift carpet and padding if the water was contaminated — leave it for a crew in protective gear
• Do not place newspaper or towels on wood flooring and leave them, since they can transfer ink and hold moisture
• Do not use your central air handler or furnace if the ducts or the unit itself were submerged
• Do not wait for the smell to develop before acting; the smell means growth has already started

Why Hour One Matters Most

Once water leaves a pipe, it begins moving outward through the structure. It travels through the carpet into the padding, from the padding into the subfloor, and from the subfloor into the bottom plate of the wall. Drywall wicks water upward through its paper facing, which is why a two-inch flood often produces a ten-inch repair. Particleboard cabinet bases and laminate floors swell and delaminate. Mold can begin colonizing wet porous materials within 24 to 48 hours.

None of that is reversible by waiting. Extraction within the first hour usually means drying equipment, a few days of patience and a bill that stays in the thousands. Extraction two days later usually means cutting out drywall, replacing flooring and treating the framing. The gap between those two outcomes is a phone call.

Homeowners in Richmond, Virginia Beach and Roanoke can reach a live dispatcher at any hour. Describe what you see and the water gets moving in the right direction.
