In the aftermath of a flood, the immediate concern for commercial building owners is understandably the clean up and flood damage restoration process. The sight of waterlogged spaces and damaged infrastructure paints a stark picture of the havoc wrought by the deluge. But as the waters recede and the initial clean up concludes, there’s a silent, lingering threat that often goes unnoticed: mould. In the Australian climate, where humidity can provide the perfect breeding ground, mould growth after flooding is a persistent issue. So, the battle against flooding doesn’t stop at clean up or restoration; it extends into the long-term prevention of mould growth. With this quick guide, we’ll help you prevent persistent mould growth after flooding.

How to Stop Mould from Growing After Flooding: Battling the Invisible Enemy

When it comes to mould, prevention is key. Here are some crucial steps to take immediately after flooding or water damage to halt the growth of this unwelcome guest:

  1. Prioritise Swift Water Extraction: The clock is ticking from the moment flooding occurs. Ensure water is extracted promptly from your commercial space to limit the moisture available for mould to thrive. High-powered water extraction equipment can be invaluable in this effort.
  2. Perform Thorough Drying: Want to prevent mould growth after water damage? Proper drying is essential. Use commercial-grade dehumidifiers and fans to dry out affected areas, including walls, floors and ceilings. Don’t forget to pay special attention to hidden corners & spaces like wall cavities and underfloor areas.
  3. Remove Damaged Materials: Get rid of any material that can’t be thoroughly dried within 48 hours, such as soaked drywall or insulation. That’s because mould can start breeding in these materials even after they appear dry.
  4. Disinfect and Clean: Clean all surfaces and belongings that came into contact with floodwater with an appropriate disinfectant. This step is crucial, as it helps eliminate mould spores that may have already settled.
  5. Ensure Ventilation: Maintain good airflow in affected areas to prevent moisture build-up. Whether the flood damage is your shop or warehouse, you can utilise open windows, fans or dehumidifiers to aid in air circulation.
  6. Seal Vulnerable Areas: After flood clean up, look out for significant cracks or gaps in your building’s structure and seal them to prevent moisture infiltration. Ensure that roofs and foundations are also properly sealed to keep water out.
  7. Perform Regular Inspections: Weeks or months after flooding or water damage, conduct regular inspections of your building for signs of mould or moisture build-up. That way, you can keep mould issues at bay and maintain a healthy environment for your staff, clients and guests.
