What should you do first when water is coming into your house?
In the first hour of a water leak, shut off the water at the fixture or at the main, cut power to the wet area at the breaker only if you can reach the panel while standing somewhere dry, photograph everything before you move it, then get standing water and wet soft materials off the floor and call a restoration contractor.
Water damage is not a single event, it is a clock. Clean water that sits on a hardwood floor for an hour is usually a drying job. The same water after two days has swollen the boards, wicked up the drywall and soaked the subfloor underneath, and the job changes from drying to removal and rebuild. Almost nothing in that difference is about equipment. It is about what happened in the first hour.
Shut the water off before anything else
Every other step is wasted while water is still arriving. If the leak is at a fixture, there is usually a small shut-off valve directly under the sink or behind the toilet. If it is a supply line, a water heater or something inside a wall, you want the main shut-off for the house.
In most King County homes the main is in the garage, in the crawlspace, or on an exterior wall near where the service line enters. Older Seattle and Renton houses often have it in a basement near the front wall. There is also a meter box at the street with a valve in it, which needs a meter key but works when nothing inside the house will turn.
Find yours now, while the floor is dry, and tell everyone in the house where it is. People lose ten minutes of a flood looking for a valve they have never touched.
Deal with electricity, but only if you can do it safely
Water and power in the same room is the one part of this that can actually hurt you. If the breaker panel is somewhere dry and you can get to it without walking through water, turn off the circuits feeding the wet area.
If the panel is in the wet area, or you would have to stand in water to reach it, do not. Leave it, keep people out of the room, and say so when you call. That is a job for the utility or an electrician, not for you in socks.
Photograph it before you clean it
This is the step people skip and regret. Your insurer is going to assess a loss it never saw, from whatever evidence exists. Once you have mopped, the evidence is gone.
Take wide shots of each affected room from the doorway, then close-ups of the source, the standing water, the wet flooring, the wet drywall at the base of the walls, and anything damaged that was sitting on the floor. Get the water line on the wall if there is one. Photograph the serial plate on a failed water heater or appliance before it is hauled out.
Keep every photo. Keep the receipt for anything you buy during the emergency. Keep the ruined items, or at least photograph them, until the adjuster has seen the file.
Get the water and the wet soft things off the floor
Standing water is doing damage every minute it sits, and the things that hold it against the floor are the worst offenders. Pull up rugs. Lift furniture off wet carpet, or slide foil or a plastic lid under the legs, because wood and metal feet stain carpet and wet carpet stains hardwood.
A wet/dry vacuum or a mop gets the surface water. Do not pull up the carpet itself, do not start cutting drywall, and do not pull up flooring. Those are decisions that depend on what is underneath and, in an older house, on whether the material has been surveyed first.
Open interior doors and closet doors so air can move. Do not point a household fan at a wall cavity and assume you have solved it. A box fan moves room air; it does not dry a soaked subfloor, and warm moving air with nowhere to go just spreads moisture into dry rooms.
Know when not to touch it at all
If the water came from a toilet trap, a sewer line, a floor drain or a backed-up main, it is contaminated and the rules change. Keep people and pets out of it entirely, do not run a household vacuum through it, and do not try to clean it with a mop and a bucket. That is a protective-equipment job.
If the water came through the roof during a storm, the ceiling above you is now holding weight it was not designed for. A sagging or bulging ceiling can come down in one piece. Get out from under it.
Make the call, and have five answers ready
Call before you are sure how bad it is. The honest version of the conversation is quick, and it is much easier to stand a crew down than to catch up to two days of wicking.
What helps on that call: the address, whether the water is still running or shut off, roughly how long it has been wet, what it touched (carpet, hardwood, drywall, crawlspace, finished basement), and whether it is clean water or a drain backup. If you only know that there is water and you are panicking, call anyway.
Why the source matters as much as the water
A restoration company can extract the water and dry the building, but a restoration licence does not permit it to repair the failed supply line, water heater or drain that caused the loss. A plumbing company can repair that, but it has no reason to be there once the water is off, and no equipment to dry the structure.
WA Mitigation holds the Washington plumbing contractor licence and the general contractor registration under one UBI, which is why the repair, the drying and the rebuild can be arranged as one job instead of three.
