I’ve been in the mould remediation industry for years now, and I can confidently say this: Queensland is facing a serious mould problem – and it’s only getting worse.
Between our long stretches of humid weather and the recent wave of storms, we’re seeing a spike in mould growth in homes across Brisbane and surrounding metro areas. It’s not just unsightly – it’s a genuine health hazard, and more property owners are getting caught off guard than you might think.
Recent data reported by RealEstate.com.au revealed something alarming: 72% of Queensland residents don’t know if mould is even covered by their home insurance. That’s three-quarters of households potentially unprotected against a problem that’s growing – literally – in their walls, ceilings, and carpets.
To make things worse, nine out of ten of Australia’s worst weather hotspots are right here in Queensland. That’s according to Suncorp, who linked extreme weather patterns to increased mould risk. The takeaway? If you own a property in Queensland, especially in metro areas like Brisbane, Gold Coast or Logan, mould isn’t just likely – it’s inevitable unless properly managed.
Many homeowners resort to household bleach or off-the-shelf mould sprays. While these can reduce the visible signs of mould temporarily, they often fail to address the deeper issue. Mould tends to grow beneath the surface, especially in porous materials like plaster, timber and grout.
Overuse of chemical treatments can also lead to poor indoor air quality, especially in poorly ventilated spaces. Some people with asthma or sensitivities may experience worsened symptoms when exposed to bleach-based cleaners.
There are non-toxic, enzyme-based solutions available that are designed to neutralise mould spores at their source. These methods aim to:
While such treatments can be more complex to apply, they are increasingly preferred by professionals and property managers seeking lasting results. Some providers also include a retention guarantee – ensuring the mould does not return for a specified period under normal living conditions.
In Queensland, rental property standards include ensuring homes are free from hazards, including mould. According to tenancy regulations, landlords are responsible for addressing mould that arises from structural issues or storm-related damage.
Some best practices include:
Refer to the Queensland Residential Tenancies Authority (RTA) for detailed legal responsibilities and guidance.
Preventing mould is often easier and more cost-effective than removing it. Here are a few evidence-based tips:
Resources like Asthma Australia offer helpful advice on how to minimise exposure and health risks.
At Xspor Australia, we’ve worked with hundreds of Queensland homeowners, landlords and commercial property managers to provide long-term mould remediation solutions. Using non-toxic, enzyme-based treatments, we help ensure healthier indoor environments while addressing the underlying causes of mould growth.
Our approach focuses on education and prevention – not just reactive fixes. Over the years, we’ve supported schools, rental property managers and residential clients across Brisbane, the Gold Coast and other metro areas in Queensland. Our commitment to safe, evidence-backed methods is part of what’s helped us build trust in a region increasingly affected by moisture-related damage.
As Queensland continues to experience warmer, wetter conditions, the risk of mould is set to remain high. Understanding how mould forms, spreads and can be safely treated is essential – especially for homeowners, tenants and property managers in high-risk regions.
This isn’t just about keeping your home clean. It’s about protecting your health, your tenants, and the structural integrity of your property.
