How to Tackle and Overcome a Mould and Damp Outbreak

The arrival of cooler temperatures, some Autumnal rain and most Queenslander’s inability to cope with the cold, has heralded the early arrival of mould in many Brisbane homes. If you’ve noticed a few of the common black specs appearing, it’s time to take action now, before your coping with a full outbreak as excess moisture can lead to mould growth, structural damage, and various health problems.

Here are some effective strategies and tools to help manage and reduce indoor humidity.

  1. Fix Leaks and Seal Drafts Immediately: Address any leaks in your plumbing or roof promptly. Use weatherstripping to seal drafts around windows and doors, preventing humid air from entering your home.
  2. Use Absorbent Materials: Place moisture-absorbing materials like silica gel, activated charcoal, or baking soda in problem areas like wardrobes and bathrooms. These materials can help reduce humidity in specific spots.
  3. Limit Indoor Moisture Sources: Reduce activities that increase humidity, such as boiling water for long periods or drying clothes indoors. Take shorter, cooler showers, open windows and always use exhaust fans during and after these activities.
  4. Opt for Humidity-Absorbing Houseplants: Some houseplants, such as peace lilies and English ivy, can help absorb moisture from the air, and reduce indoor humidity levels.
  5. Insulate Your Home: Proper insulation maintains consistent temperatures, reducing the likelihood of condensation and mould growth. Pay special attention to garages and crawlspaces, where moisture problems are more common.
  6. Use a Pedestal Fan: Mould hates airflow, so enhancing air circulation in a smaller space can help to reduce humidity levels. Check out the Pedestal Fan(https://centenaryhire.com.au/hire/pedestal-fan/) for targeted airflow in specific areas.
  7. Warm up the Space with a Space Heater: In colder months, a space heater can help maintain a warm environment, preventing moisture build-up. Consider the Space Heater for efficient heating solutions.
  8. Electric Heat Gun: For localized drying and moisture control on a job site, the Electric Heat Gun is a versatile tool that can be used in various applications.
  • Utilise a Carpet Dryer: For damp carpets or flooring, using a carpet dryer can expedite the drying process and prevent mould growth. This tool is essential for quickly drying wet carpets and floors, reducing the risk of mold and mildew.

However, if the above ideas don’t work, or you’ve already got a mould infestation, you may need to consider professional tools such as dehumidifiers and extraction fans.


Dehumidifiers are essential for reducing moisture levels in the air. These devices work by drawing in humid air, cooling it to condense the moisture, and then expelling the drier air back into the room. For larger spaces or significant moisture problems, consider hiring an industrial-grade dehumidifiers:


  • 100L Dehumidifier: This high-capacity dehumidifier is ideal for large areas with severe moisture issues. It effectively reduces humidity levels quickly and efficiently.
  • 80L Dehumidifier: Slightly smaller than the 100L model, this dehumidifier is suitable for medium to large spaces and provides robust moisture removal.

Improve Ventilation

Proper ventilation is crucial in managing indoor humidity. Extraction fans can help remove moist air from specific areas, such as bathrooms and kitchens, which are prone to high humidity:

  • 300mm Extraction Fan: This fan is perfect for smaller spaces that require targeted moisture control, helping to expel humid air efficiently.
  • 600mm Extraction Fan: For larger areas, this powerful fan provides enhanced air circulation, significantly reducing humidity levels.

Implementing these strategies and utilizing the right tools can help you effectively control dampness and humidity in your home. By doing so, you’ll minimize the risk of mould, improve air quality, and enhance overall comfort. For more detailed information and product options, visit Centenary Hire.
