What to Do in the First 48 Hours After Storm Water Enters Your Home

By Brandon Cordoves - June 15, 2026

When storm water gets into your home, the next two days matter more than anything else you will do. In the South Florida heat and humidity, mold can start growing on damp materials within 24 to 48 hours. Here is the order of operations that gives you the best outcome.

1. Stay safe first. Do not enter standing water if power is still on to that area. Watch for sagging ceilings, which hold weight you cannot see.

2. Stop the source if you safely can. A tarp over a roof breach or a towel-dam at a window can slow active intrusion until help arrives.

3. Document before you clean. Photograph and video everything: the water line, soaked materials, damaged contents, and the source if visible. This record is what your insurer and a licensed inspector will rely on. Do not throw anything out until it is documented.

4. Get it dry, fast. Move wet contents out, pull up soaked rugs, run fans and a dehumidifier, and open the space up if outdoor humidity allows. The goal is to beat that 24 to 48 hour window.

5. Find the water you cannot see. Water travels. A wet baseboard often means a wet wall cavity. This is where most homeowners stop too early. Our guide on spotting hidden mold covers the signs.

6. Know your line. If the water sat, spread behind walls, or smells musty, it is time for a professional. See DIY vs professional remediation.
