24/7 Emergency Response Across Lismore
For generations, Lismore has lived with the Wilsons River. But the 2022 floods were different, reaching a record 14.4 metres and leaving behind a level of devastation our community had never seen. The water receded, but the real, quiet crisis was just beginning: mould. Not just any mould, but aggressive, fast-growing colonies fed by a contaminated mix of floodwater, mud, and sewage that penetrated deep into wall cavities, sub-floors of raised Queenslanders, and the frames of homes across South and North Lismore. Lismore’s subtropical climate, with its high year-round humidity, now acts as an incubator.
At Water Damage Lismore, our approach to mould remediation is shaped by our direct experience during and after the 2022 disaster. Our work is more than cleaning; it’s a critical part of making homes safe to return to. We provide a comprehensive remediation service grounded in the ANSI/IICRC S520 Standard for Professional Mould Remediation, a framework we adapt to the unique challenges of flood-damaged properties in the Northern Rivers. Our IICRC-certified technicians diagnose the hidden moisture sources that persist long after the floodwaters are gone, establish rigorous containment to protect your family, and physically remove the contamination to restore healthy living conditions. We were here for the cleanup, and we are here for the recovery, serving the entire Lismore region 24 hours a day.
Understanding Mould Remediation in the Lismore Context
Post-flood mould remediation is a systematic, documented process to identify, contain, and physically remove mould from a structure. It is not spraying bleach on a wall. The IICRC S520 standard, which guides every step we take, prioritizes source removal. This means physically cutting out and disposing of compromised materials, not just treating the visible surface. After an event like the 2022 flood, mould is never just on the surface; it’s deep in the building’s structure.
The process begins by identifying the persistent moisture source. In Lismore, this is rarely a simple leaking pipe. It’s often moisture trapped in concrete slabs, dampness wicking up timber stumps under a house in Girards Hill, or compromised waterproofing in a home in East Lismore. Without correcting this underlying dampness, mould will always return. Our approach involves setting up full-scale containment with negative air pressure systems to prevent cross-contamination and using commercial-grade HEPA-filtered air scrubbers to capture the millions of airborne spores released from disturbed materials. We verify the structure is clean and, just as importantly, dry before we consider a project complete.
Our IICRC S520 Flood Mould Remediation Process: A Step-by-Step Breakdown
Inspection & Moisture Mapping
We conduct an exhaustive assessment using FLIR thermal imaging cameras, penetrating moisture meters, and hygrometers to map the full extent of water intrusion. This allows us to see what the naked eye cannot: the cold spots behind walls and under floors where moisture is trapped, feeding mould colonies long after the 2022 flood.
Containment & Engineering Controls
We establish critical containment barriers using heavy-duty 6-mil polyethylene sheeting. Negative air pressure is created using HEPA-filtered air filtration devices (AFDs), ensuring that all airborne particles, including dangerous spores like Stachybotrys, are captured and that air flows into the contaminated area, not out into the clean areas of your home.
Source Removal of Contaminated Materials
Following the S520 protocol, all porous materials saturated by floodwater, such as plasterboard, timber flooring, and insulation, are carefully removed and bagged for disposal according to local guidelines. We document this process for insurance purposes, which is critical for claims with insurers like Suncorp, Allianz, and RAC who we work with regularly.
HEPA Filtration and Decontamination
High-efficiency particulate air (HEPA) vacuums and industrial air scrubbers are run continuously throughout the project. These machines filter the air to 99.97%, capturing microscopic mould spores and dust particles, ensuring the air within the containment zone is thoroughly cleaned before barriers are removed.
Moisture Source Correction & Structural Drying
This is the most critical phase in Lismore's humid climate. We deploy a fleet of refrigerant and desiccant dehumidifiers and high-velocity air movers to aggressively dry the structure. We address the source, whether that involves recommending sub-floor ventilation improvements for a home in the Lismore Heights area or advising on drainage corrections for a property near Leycester Creek.
Post-Remediation Verification
The contained area is meticulously inspected to ensure no visible contamination remains and that all materials have returned to their normal, dry moisture content. For situations requiring absolute certainty, such as for immunocompromised residents, we can coordinate with an independent Environmental Hygienist to perform third-party air and surface sampling.
Specialised Mould Remediation for Lismore Properties
We provide a complete range of services specifically designed to address the complex mould issues found in post-flood Northern Rivers properties.
Mould Inspection
Our IICRC-certified technicians perform comprehensive visual inspections and moisture mapping. We know where to look in Lismore homes: behind skirting boards, inside wall cavities of older fibro cottages, and in the sub-floors of weatherboard homes that were inundated for days.
Mould Testing and Sampling
While not always required, air and surface sampling can provide documented proof of the types of mould present (e.g., Aspergillus, Penicillium, Stachybotrys) and their concentration. This data is invaluable for complex insurance claims or when occupants have pre-existing health conditions that make them vulnerable to mould exposure. We coordinate all testing through an independent, accredited laboratory.
Mould Removal and Cleaning
Our core service involves the controlled removal of contaminated materials and the aggressive drying of the remaining structure. We use industry-approved antimicrobial treatments on cleaned, non-porous surfaces and follow strict protocols for the safe handling and disposal of flood-damaged building materials like ironbark, spotted gum, and pine framing common in local construction.
HVAC and Duct Mould Cleaning
Mould thrives in dark, hidden spaces. Floodwater often introduces contaminants into sub-floor areas and HVAC systems. We offer specialised cleaning services for these areas to remove mould spores and silt deposits from air circulation systems and the foundational structures of your home, crucial for restoring healthy indoor air quality.

Frequently Asked Questions About Mould Remediation in Lismore
In Lismore’s subtropical climate, mould growth begins within 24-48 hours. After the 2022 floods, with high humidity and contaminated silt providing nutrients, we saw significant colonies appear in under 24 hours. Rapid, professional drying is the only way to prevent it.
Yes. Floodwater is a Category 3 contamination event, containing sewage, agricultural runoff, and chemicals. Mould growing in this environment can be more hazardous. Individuals with asthma, the elderly, children, and the immunocompromised are at a significantly higher risk and should not live in flood-affected, unremediated properties.
When performed correctly by IICRC-certified professionals, it is extremely safe. Our use of critical containment, negative air pressure, and constant air filtration isolates the work area completely, protecting your family from any exposure.
A small, contained bathroom issue might take 2-3 days. A full ground-floor remediation of a flood-damaged house in South Lismore, involving removal of walls and flooring, can take one to two weeks to allow for the essential structural drying phase before any rebuilding can commence.
Yes, if the underlying moisture problem is not solved. This is the difference between a handyman with a spray bottle and a certified remediation firm. A core part of our job is to identify and help fix the moisture source, which is the only long-term solution to prevent regrowth, especially with the Wilsons River in our backyard.
