What to do right now

While help is on the way, these first steps, done only where it is safe, limit the damage and protect the insurance claim.

1

Stop the water

Shut the supply off at the source, or close the home's main valve if the source is not obvious. Stopping the flow limits the damage more than anything else.

2

Cut the power

Switch off electricity to the affected area, but only if the breaker can be reached without standing in or touching the water.

3

Call for help

Get a crew dispatched right away. The sooner extraction and drying begin, the more flooring, drywall, and belongings can be saved.

4

Document the loss

Take photos and a short video of the water and the affected rooms before anything is moved, so the insurance claim starts strong.

Good questions

Water Main Break Flooding, answered

Crews typically dispatch within 30 to 60 minutes of the call and begin extraction immediately. Call (314) 762-6284 anytime, day or night.

Mold can begin growing within 24 to 48 hours in humid conditions. Fast extraction and proper drying prevent it, with moisture levels monitored continuously until the space is verified dry.

Most policies cover a sudden break in the water main or service line, including emergency extraction and drying, and the claim is documented to support the adjuster's review.

Drying typically takes 3 to 7 days depending on water volume, room size, and humidity, with moisture meters and daily monitoring tracking progress.

Extraction and drying work the same way once a slab leak is found. Locating and repairing a pinhole leak under a slab is a job for a plumber who specializes in that kind of repiping.
