Whether it's a burst supply line, a failed water heater, or storm water finding its way inside, the first hour after you discover a flood matters more than any hour that follows. What you do — and don't do — in that window affects your safety, how much can be saved, and how smoothly an insurance claim goes later.

Safety Comes First

Before you touch anything, look at the bigger picture. If water is near electrical outlets, panels, or appliances, or if you smell gas, leave the area and don't re-enter until it's been checked. Standing water and electricity are a dangerous combination, and no amount of furniture or flooring is worth that risk.

Stop the Source If You Can

If the water is coming from a identifiable source inside the home — a supply line under a sink, a washing machine hose, a toilet — look for the local shutoff valve first, since it's faster than finding the main. If you can't locate it or the source isn't obvious, shut off the home's main water supply. This alone can be the difference between an inch of water and a foot of it.

Turn Off Electricity to Affected Areas

If it's safe to reach your electrical panel without stepping through water, switch off power to the affected rooms. If the panel itself is in or near the flooded area, don't attempt it — wait for a professional instead.

Start Documenting Before You Start Cleaning

It's tempting to start mopping immediately, but a few minutes with your phone camera first will make an insurance claim much easier. Photograph the standing water, the source if visible, and any furniture, flooring, or belongings that are affected. Wide shots and close-ups both help.

Move What You Can, Safely

Lift furniture legs onto blocks or foil, move rugs and unsecured items to a dry area, and pull anything valuable or irreplaceable out of harm's way if you can do so without wading through deep or contaminated water. Don't strain yourself moving heavy, waterlogged furniture alone.

Call for Help

Once the immediate safety steps are handled, call a restoration company. Water that sits for even a few hours starts moving into subfloors, baseboards, and wall cavities — areas a mop can't reach. Water extraction and full water damage restoration both start with getting equipment on-site as quickly as possible, so the sooner you call, the less the water has a chance to spread.

What Not to Do

  • Don't run a shop vac or household electronics through standing water without confirming power is off in that area first.
  • Don't wait until morning if the flooding is active and spreading — call for help the moment it's safe to do so.
  • Don't assume carpet or drywall is fine just because it looks dry on the surface.
  • Don't throw away damaged items before photographing them for your insurance claim.

The first hour is about limiting damage and staying safe — not fixing everything yourself. A restoration crew can pick up from there with the equipment and documentation an insurance claim actually needs.
