What to Do in the First 24 Hours After Water Damage

The first day after a water loss decides how much you lose. Here's exactly what to do — and what to avoid — in the critical first hours.

Water damage is a race against the clock. Within hours, water wicks into drywall, flooring, and framing; within 24–48 hours, mold can begin to grow. What you do in the first day has an outsized effect on how much is damaged, how much it costs, and how smoothly your insurance claim goes.

This guide walks through the steps that matter most in the first 24 hours after discovering water damage in your Treasure Valley home.

1. Make Sure It's Safe

Before anything else, protect people. Water and electricity are a dangerous combination, and contaminated water carries health risks.

  • If water is near outlets, wiring, or your panel, shut off electricity to the affected area — only if you can reach the breaker safely and without standing in water.
  • Avoid contact with water that may be contaminated (sewage backups, flood water).
  • Watch for slip hazards and sagging, water-laden ceilings.

2. Stop the Source

If the water is coming from your plumbing, shut off the supply. For a single fixture, use its local shutoff; for a larger or unknown source, shut off the main water valve to the house. Stopping the flow is the single most important thing you can do to limit damage.

3. Call for Professional Help

Call a restoration company as early as possible. Fast professional extraction and drying is what prevents a manageable loss from becoming a gut-and-rebuild. A 24/7 company can talk you through the next steps and dispatch a crew — often before more damage sets in.

4. Document Everything

Before you move or clean anything, document the damage for your insurance claim. Good documentation now protects you later.

  • Take photos and videos of all standing water, damaged areas, and affected belongings.
  • Note when you discovered the damage and what you think caused it.
  • Keep receipts for anything you buy in response (tarps, a hotel if displaced, etc.).

5. Mitigate Where You Safely Can

While you wait for help, you can take a few safe steps to limit damage — but don't put yourself at risk or use equipment in standing water.

  • Move valuables, electronics, and furniture out of the water if it's safe to do so.
  • Blot or mop up what you can; lift curtains and fabrics off wet floors.
  • Do not use a household vacuum to remove water, and do not use ceiling fixtures if the ceiling is wet.

6. Notify Your Insurer

Report the loss to your insurance company promptly. Share your documentation, and ask about your coverage and deductible. A restoration company experienced with claims can document the loss in the detail your insurer needs and coordinate directly with your adjuster.
