What to Do Immediately After Water Damage (First 24 Hours)

Updated July 28, 2026

Act fast — water spreads in minutes, mold in hours

Water wicks into drywall, subfloor, and framing within minutes, and mold can begin within 24–48 hours. What you do in the first day has the biggest impact on how much gets damaged and how much your restoration costs.

Do these first

  1. Stop the source — shut off the water main if it's a plumbing failure.
  2. Kill the power to affected areas if it's safe to reach the breaker — never enter standing water with live electricity.
  3. Call a restoration pro — fast extraction and drying is what prevents mold and structural damage. We answer 24/7.
  4. Document everything — photos and video of the damage before you move anything, for your insurance claim.
  5. Move what you can — lift furniture, rugs, and valuables out of the water if safe.

Don't do these

  • Don't use a household vacuum to remove water
  • Don't wait to "see if it dries on its own" — hidden moisture causes mold
  • Don't throw everything out before documenting it for insurance

Frequently Asked Questions

Should I call my insurance or a restoration company first?

Call a restoration company first for active damage — fast mitigation limits the loss (and insurers expect you to prevent further damage). We can document everything for your claim as we work.

How fast do I really need to act?

Immediately. Mold can start within 24–48 hours, and drying costs rise the longer water sits. We respond 24/7, often within the hour.
