Measuring Moisture in an open wall

Flood-damaged homes need immediate attention to prevent mold growth, which can begin to grow within 2-3 days on materials that have gotten wet. Mold may serious health risks, especially to children, the elderly, and those with existing health conditions.

It can trigger allergic reactions or asthma episodes. If your home has flooded here is how to handle mold effectively:

  1. Act Quickly: Begin cleanup as soon as it’s safe. Take photos for insurance, but
    don’t wait for an adjuster to remove wet and moldy materials. Note that most
    homeowners’ insurance does not cover mold, but flood insurance might.
  2. Wear Protective Gear: Use gloves, goggles, disposable covering, and an N-95
    respirator during cleanup to avoid exposure.
  3. Isolate and Ventilate: Seal off moldy areas and ventilate to the outdoors to
    prevent spore spread.
  4. Remove Moldy Materials: Dispose of porous, water-damaged materials like
    carpets, insulation, and drywall. Salvage valuable items only if cleaned and dried promptly.
  5. Clean and Disinfect: Clean non-porous materials with non-phosphate cleaners
    and use disinfectants carefully. Avoid mixing bleach with ammonia.
  6. Speed Dry: Use fans, dehumidifiers, and air conditioning to dry materials quickly. Check moisture levels in wooden studs with a moisture meter to ensure they are 15% or below before restoring.
  7. Stay Vigilant: Monitor for new mold growth, which can appear within days if
    moisture remains. If mold returns, repeat the cleaning and drying process.

Hiring a mold remediation contractor is advised for severe infestations. For detailed
guidance, visit EPA’s or CDC’s mold remediation resources online. Prompt action can protect your health and help restore your home effectively.

HUD’s Rebuild Healthy Homes is a valuable resource  for those who need to clean-up
and repair homes damage  by any type of natural disaster. The Rebuild Healthy Homes: Guide to Post-disaster Restoration for a Safe and Healthy Home is a detailed and comprehensive how-to guide available online, as a free pdf for download. Even more useful for those actively working on a home is the Rebuild Healthy Homes app which you can access information via HUD’s website.
