Keeping Mould Out: Practical Tips for Australian Homes in Damp Weather

Mould Prevention Tips for Damp Australian Homes

In the current wet and humid conditions impacting much of Queensland and other lush, vegetated areas across Australia, many homeowners are facing a common foe: mould. Not only unsightly, mould can also impact your health and damage your property if left unchecked.

At Xspor Australia, we specialise in mould prevention and remediation across Australia and New Zealand. Today, we’re sharing essential strategies every homeowner should follow to reduce the risk of mould taking hold.

Useful Advice

1. Mind Your Windows: Stop Condensation Before It Starts

Windows are one of the most vulnerable points in your home when it comes to mould, primarily due to condensation. Moisture builds up when warm indoor air hits cold window glass, creating an ideal environment for mould spores to settle and spread. The base of the window frame, especially where the glass meets timber or aluminium, is often the first place you’ll see it.

Prevention tips:

  • Regularly clean window frames, sills, and surrounding walls with dishwashing liquid, rinse thoroughly, and dry.
  • Use a microfibre cloth to wipe away daily condensation each morning.
  • Install weather stripping or window insulation film to reduce cold surfaces.
  • Apply anti-fungal sealants or treatments to timber frames if mould is a recurring issue.
  • Keep windows shut on damp or humid days; instead, use your air-conditioner’s dry cycle or maintain temperature at 22°C.
  • Run ceiling fans daily to help air circulate, particularly in bedrooms and living spaces.

2. Stay on Top of Indoor Cleaning: Dust + Moisture = Mould Fuel

Mould feeds on organic matter, including dust, skin cells, and household grime. Combine this with high humidity, and you’ve got a breeding ground.Mould prevention
is not just about drying out your home but keeping it clean as well.

Routine mould-prevention cleaning includes:

  • Vacuuming floors and carpets weekly with a HEPA filter vacuum cleaner.
  • Dusting all surfaces, especially around vents, window tracks, and ceiling fans.
  • Using white vinegar or clove oil (diluted in water) as a natural surface cleaner to kill spores.
  • Washing curtains and soft furnishings regularly.
  • Avoiding clutter, which can restrict airflow and trap moisture behind furniture.

3. Don’t Ignore Outdoor Surfaces: Spores Travel In

Outdoor mould on driveways, patios, and decking may seem harmless—but spores are airborne and easily tracked indoors via shoes, pets, or air flow through open doors and windows.

Here’s how to stop it at the source:

  • Use a high-pressure hose to clean concrete, tiles, and timber surfaces.
  • Sweep and treat moss or mould on footpaths and retaining walls.
  • Maintain your garden to ensure leaves and mulch aren’t accumulating near doorways.
  • Check outdoor furniture and soft surfaces (like shade sails or umbrellas) for mould growth and treat promptly.

4. Airflow Over Open Windows: The Humidity Trap

Fresh air is healthy—but only if it’s not saturated with moisture. In high humidity, opening windows can increase indoor condensation. That’s why controlled airflow is often better than natural ventilation during wet weather.

Instead, do this:

  • Run your air-conditioner’s dry mode or set it to 22°C for climate balance.
  • Use dehumidifiers in musty rooms or storage spaces.
  • Ensure bathroom and kitchen exhaust fans vent outdoors (not just into roof cavities).
  • Leave wardrobe doors slightly ajar and install louvre vents for passive airflow.
  • Avoid drying clothes indoors if possible, or ensure the area is well-ventilated.


5. Mould Is Natural – But Not Welcome Indoors

Mould spores are part of the natural environment—essential outdoors for decomposing organic matter. But inside, they act like silent saboteurs, feeding on building materials, furnishings, and even clothing.

Once mould is visible, it’s likely there are thousands of invisible spores circulating through your air. Addressing only surface mould doesn’t solve the root problem.

Preventive lifestyle tips:

  • Use moisture-absorbing crystals or silica gel in wardrobes and pantries.
  • Keep pets’ bedding clean and dry, especially in wet weather.

Regularly inspect rarely accessed areas: under sinks, inside cupboards, behind large furniture.
