What to Do in the First 24 Hours After Water Damage

A burst pipe, a roof leak, an overflowing appliance — water damage almost always arrives without warning, and it gets worse by the hour. What you do in the first day makes a real difference in how much gets damaged, how much it costs, and whether mold takes hold. Here's a calm, clear plan for those first 24 hours.

1. Stay Safe First

Before anything else, make sure it's safe. If water is near electrical outlets, panels, or appliances, shut off the power to that area at the breaker — never walk into standing water with the electricity on. If you suspect the water is contaminated (from sewage or flooding), keep your distance and let professionals handle it.

2. Stop the Source

If you can safely do it, stop more water from coming in. That might mean shutting off your home's main water valve, turning off a specific fixture, or placing a bucket under an active leak. Stopping the flow is the single most important thing you can do early.

3. Document Everything for Insurance

Before you start cleaning up, take photos and videos of all the damage — the water, affected rooms, furniture, and belongings. This documentation is important for your insurance claim. It's also wise to contact your insurance company early to understand what's covered and what they need from you.

4. Start Removing Water and Protecting Belongings

Once it's safe, begin removing standing water with towels, mops, or a wet/dry vacuum, and move furniture and valuables to a dry area. Lifting wet rugs and getting air moving helps limit how far the damage spreads while you wait for help.

5. Get Air Moving

Open windows, run fans, and use a dehumidifier if you have one. The faster a space dries, the less likely mold is to develop — and that window is short.

What Not to Do

• Don't wait. Water damage compounds quickly, and "I'll deal with it tomorrow" often turns a small problem into a large one.

• Don't use a household vacuum to suck up water — it's not built for it and can be dangerous.

• Don't assume it's dry because the surface looks fine. Water hides inside walls, under flooring, and in cavities you can't see.

  
  

Why the Clock Matters: Mold

Here's the part most people don't realize — mold can begin to grow within roughly 24 to 48 hours of water exposure. That's why fast, thorough drying is so critical, and why hidden moisture inside walls and floors is so risky. Surface cleanup isn't always enough; the moisture you can't see is what leads to mold and structural problems weeks later.

When to Call a Professional

For anything beyond a small, contained spill, professional help is the safest call. A remediation team has the equipment to find hidden moisture, dry the space completely, and restore what was damaged — stopping the problem before it becomes mold or rot.
