Why Mold Grows After Water Damage
Mold can begin growing in as little as 24–48 hours after a leak, burst pipe, sewage backup, or flood. Moisture trapped inside walls, under flooring, or in insulation creates the perfect environment for spores to spread — often without visible signs at first. Even a small amount of water can lead to serious mold growth if not addressed quickly and properly.
How to Prevent Mold Growth After a Leak or Flood
- Act fast: Begin drying the area within 24 hours using high-volume fans and dehumidifiers. Mold thrives on prolonged moisture.
- Remove water-damaged materials: Carpets, drywall, baseboards, and insulation that cannot be dried within 48 hours should be removed and discarded.
- Use proper ventilation: Increase airflow with windows, air movers, and your HVAC system (if safe). Stagnant air allows moisture to linger and mold to spread.
- Disinfect hard surfaces: Clean non-porous areas with an EPA-approved antimicrobial cleaner to kill bacteria and fungi left behind by water damage.
- Check for hidden moisture: Use a moisture meter or infrared camera to detect wet areas inside walls, behind cabinets, or under flooring — even if the surface feels dry.
Get a Mold Inspection After Water Events
Even when surfaces appear dry, hidden moisture can remain inside building materials, leading to hidden mold. A certified mold inspection can catch problems early and help prevent future health issues or costly remediation.
If your home recently experienced flooding, a roof leak, burst pipe, or any Category 2/3 water event — schedule an inspection to ensure everything is truly dry and safe.
