Water damage is a race, and the clock starts the moment the pipe lets go. Drywall wicks water within hours. Mold can establish within 24 to 72 hours. What you do in the first day routinely decides whether you're facing a few thousand dollars of drying or a five-figure remediation and rebuild. Here's the playbook, in order.
Hour 0–1: Stop the Water, Stay Safe
Find the source and shut it off, the fixture's supply valve or, if you can't isolate it, the home's main shutoff (find yours today, before you need it). If water is near outlets, appliances, or your panel, cut power to the affected circuits before stepping in. Sewage or outdoor floodwater? Stay out entirely; that's contaminated water and a job for protective equipment.
Hour 1–2: Document, Then Call
Photograph and video everything before you move a thing: standing water, the source, affected rooms, damaged belongings. Then make two calls: your insurance carrier to open the claim, and a restoration company to start mitigation. Those happen in parallel, not sequence; your policy requires you to prevent further damage, and waiting for an adjuster while water spreads works against you. Our emergency line at 800-588-0340 is answered around the clock for exactly this moment.
Hour 2–8: Get the Water Out
Move what's saveable out of the water: furniture on foil or blocks, rugs up, electronics out. Professional extraction matters here because the water you can see is the minority of the problem: moisture meters routinely find saturation two rooms past the visible edge, inside wall cavities and under flooring. A shop vac handles a puddle; it doesn't find the water hiding in your walls.
Hour 8–24: Drying Begins (and Doesn't Stop)
Commercial air movers and dehumidifiers go in and run continuously. This is not the time for "we'll open some windows." In Western Washington's humidity, passive drying loses the race to mold nearly every time. Crews take baseline moisture readings, monitor daily, and the equipment stays until the numbers, not the calendar, say the structure is dry.
What Not to Do
Don't run your furnace fan to "help dry things". It can pull moisture and contaminants through the duct system. Don't rip out wet drywall in a pre-1990 home before asbestos is ruled out. Don't throw damaged items away before the adjuster sees them or releases them. And don't accept "it feels dry," because feeling dry and being dry are different things, and the gap between them is where mold remediation projects are born.
The Payoff for Acting Fast
Same-day extraction and verified drying routinely save flooring, drywall, and cabinetry that a slow response loses, and prevent the mold project entirely. Speed isn't a sales pitch in this trade; it's the whole physics of the problem.
