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

Updated July 28, 2026

Stay safe first

Before anything else: if water is near outlets, the panel, or any wiring, don't enter the area — shut off power to it at the breaker if you can do so safely, or wait for help. Standing water plus electricity is a serious hazard. If a ceiling is sagging from water, stay out from under it.

Stop the source

Shut off the water at the main valve (usually in the basement, garage, or near the meter) if it's a plumbing failure. If it's a storm or exterior flood, you can't stop the source — focus on safety and getting help.

Document everything for your claim

Before you move or clean anything, photograph and video the damage — the water, affected rooms, and damaged belongings. This is crucial for your insurance claim. Save receipts for anything you buy during the emergency, too.

Call a restoration company fast

Mold can begin growing in 24–48 hours, so professional extraction and drying should start as soon as possible. The faster the water is removed and the structure dried, the less damage and the lower the cost. We offer 24/7 emergency water damage restoration across Lancaster County and can document the loss for your carrier.

Frequently Asked Questions

Should I start cleaning up myself?

You can move undamaged belongings to safety and soak up standing water, but hold off on tearing anything out until it's documented — and leave contaminated water (sewage, flood water) to professionals.

How soon do I need professional drying?

As soon as possible — ideally within hours. Mold can start in 24–48 hours, and materials that could be saved with fast drying may need replacing if you wait.
