Preventing Mold After a Plumbing Leak

In South Florida's humidity, mold can start within a day or two of a leak. Learn how to dry out quickly, where mold hides, and when to call a professional.

South Florida's heat and humidity make mold a real risk after any leak. Moving fast in the first 24 to 48 hours makes the biggest difference.

Step 1: Stop the leak

Shut off the water at the fixture or main valve and get the leak repaired. Drying out a space while water is still seeping in won't work.

Step 2: Remove water and wet materials

  • Mop and wet-vac standing water.
  • Pull up wet rugs and move furniture off damp floors.
  • Remove baseboards if water got behind them so the wall can breathe.
  • Take everything out of wet cabinets.

Step 3: Dry aggressively

  • Run the air conditioning and dehumidifiers.
  • Use fans to move air across wet surfaces.
  • Keep windows closed on humid days; outside air may add moisture.

Where mold hides

  • Inside walls behind showers, sinks and water heaters
  • Under vinyl, laminate and wood flooring
  • Inside sink base cabinets
  • In drywall ceilings below bathrooms or AC units

When to call professionals

  • Water soaked drywall or insulation for more than a day or two
  • The leak came from a sewer or drain line (contaminated water)
  • You see or smell mold over a large area
  • Anyone in the home has allergies or respiratory issues

A plumber can confirm the leak is fully repaired and check for hidden leaks; a water damage or mold remediation company can dry and treat affected areas. Photos and repair documentation help with insurance claims.
