What To Do In The First 24 Hours After Water Damage

If water is actively spreading through your home right now, the next few hours matter more than almost anything else in the entire restoration process. Here's exactly what to do, and what to avoid, before help arrives and in the day that follows.

Hour By Hour: What Actually Matters

What Not To Do

A few common instincts actually make things worse. Avoid these while you wait for help:

• Don't use a household or shop vacuum on standing water. It's not built for it, and it can create an electrical hazard.
• Don't ignore water that's spread out of sight. Water travels along subflooring and behind baseboards well beyond where it's visible.
• Don't wait to see if it dries on its own. By the time you can tell it hasn't, you may already be past the window where drying alone would have worked.
• Don't throw away damaged items before documenting them. Your insurance claim depends on photo evidence of the damage as it was found.
• Don't assume a small leak means a small problem. A slow leak that's been running for days can cause more hidden damage than a sudden burst that gets caught immediately.

What To Have Ready For Your Insurance Claim

• Photos and video of the damage before anything is moved or removed, from multiple angles.
• A timeline of when you noticed the water and when you took action, even a rough one.
• Receipts for any damaged items you can find, or at minimum a list with estimated values.
• Moisture readings and documentation from your restoration company, which we provide as part of every job and can share directly with your adjuster.

After The First 24 Hours

Once extraction and drying are underway, the next priority is making sure it's actually finished, not just visibly dry. Moisture can remain trapped in subflooring, insulation, and wall cavities well after the surface feels dry to the touch. If that moisture isn't fully resolved, you're back to the same risk we cover in how water damage turns into mold, usually within 24 to 48 hours of the original event.

Frequently Asked Questions

Should I turn off the electricity before dealing with water damage?

If water is near any outlets, cords, or electrical panels, and you can safely reach the breaker without stepping through water, shut off power to the affected area first. If you're unsure, wait for a professional rather than risk contact between water and electricity.

Can I use my own vacuum to remove water?

No, a standard household or shop vacuum isn't built for standing water and can create an electrical hazard. Water extraction requires equipment specifically designed for it.

How soon do I need to call a water damage company?

As soon as possible. The first 24 to 48 hours determine whether materials can be saved through drying alone or need to be removed and replaced, so faster response directly reduces both damage and cost.
