How Fast Does Mold Grow After Water Damage in South Florida?

In South Florida, mold can begin forming within 24–48 hours when moisture is trapped in drywall, cabinets, flooring, or insulation. The faster things are properly dried, the better the chances of preventing mold from becoming a bigger issue.

What to Do If This Is Happening Right Now

  • Stop the water source if possible

  • Don’t cover up the area (painting over stains traps moisture)

  • Avoid pulling drywall or flooring yourself

  • Call for moisture detection and proper drying

  • If you smell a musty odor or have allergies, act sooner rather than later

In humid Florida conditions, moisture can linger where you can’t see it — behind walls, under floors, and inside cabinets.

Why South Florida homes are higher risk

  • Heat and humidity slow down natural drying

  • Moisture gets trapped in enclosed spaces

  • Small leaks often stay wet behind walls longer than people realize

Signs moisture may still be present

  • Musty smell

  • Bubbling paint or swollen baseboards

  • Warped/buckled floors

  • Stains that grow or darken

  • Allergy symptoms or irritation that wasn’t there before
