24/7 Emergency Response Across Lismore
As a Lismore-based company, we understand the reality of mould contamination after the record-breaking 2022 floods. The 14.4-metre peak of the Wilsons River didn’t just bring water into homes; it introduced a complex biohazard environment that standard cleaning cannot resolve. We are an IICRC-certified firm dedicated to the technical and considered remediation of mould in residential and commercial properties throughout Lismore and the Northern Rivers.
Our technicians, holding IICRC WRT and AMRT certifications, work to the AS/IICRC S520 standard, the framework recognised by Australian insurers for mould remediation. This isn’t just about compliance; it’s about providing the meticulous documentation required for your insurance claim with providers like Suncorp, Allianz, and RAC. We have direct experience navigating the claims process for properties impacted by the Wilsons River flood event, from initial moisture mapping to final clearance.
An IICRC-Certified Firm Responding to Lismore's Unprecedented Mould Challenges
The aftermath of the 2022 flood created a perfect storm for aggressive mould growth. Category 3 water, contaminated with sewage, soil, and chemicals, saturated building materials for days, and in some parts of South Lismore, for weeks. Simply spraying bleach on visible mould is not a solution. It may temporarily remove the colour, but it fails to neutralise the hyphal network growing deep within porous materials like flood-affected timber framing, plasterboard, and subfloors. Attempting to clean extensive contamination without proper containment aerosolizes millions of spores, spreading the problem into previously clean areas of a partially-damaged home.
Professional remediation acknowledges the unique challenges of our region. Our humid subtropical climate, combined with the sheer volume of water introduced during the floods, means moisture is trapped deep within the building envelope of many local homes, from older timber cottages in North Lismore to the double-brick constructions in Girards Hill. Our process begins with identifying the full extent of this moisture intrusion. The visible mould patch is often just the symptom. The real work is in finding and rectifying the underlying moisture that allows it to thrive, a crucial step to prevent recurrence and ensure the long-term health of your home and family.
Our Mould Remediation Process: Adhering to IICRC S520 Standards in a Flood Zone
We follow the procedural standard that underpins every successful insurance claim and safe remediation project in Australia. It’s a systematic approach built on verifiable science, not guesswork.
Assessment & Moisture Mapping
Our first action on a Lismore property is to understand the full scope of water impact. Using thermal imaging cameras and non-invasive moisture meters, we map the extent of water migration, often revealing hidden saturation in wall cavities and under floors that appears dry on the surface. This data is critical for building a comprehensive report for your insurer and defining the exact scope of required work.
Containment & Negative Air Pressure
The contaminated area is physically isolated from the rest of your property using 6-mil polyethylene sheeting and containment barriers. We then establish negative air pressure with HEPA-filtered air scrubbers vented to the outside. This containment strategy is non-negotiable. It ensures that as we disturb and remove mould-colonised materials, airborne spores and particulates are captured, protecting unaffected areas of your home.
Controlled Removal of Contaminated Materials
Flood-damaged porous materials like plasterboard, insulation, and carpet cannot be restored. They must be removed. Our teams carefully cut out and bag these materials in sealed disposal bags, handling them in accordance with local guidelines for contaminated waste. Many older Lismore homes contain old-growth hardwoods which, where structurally sound, can be saved. We assess this on a case-by-case basis.
Structural Decontamination
Structural elements like timber frames and concrete slabs are meticulously cleaned. This starts with HEPA vacuuming to remove surface spores, followed by damp-wiping with a registered antimicrobial solution. Our focus is always on physical removal of the mould source, a far more effective method than simply "fogging" an area with chemicals.
Structural Drying
Following decontamination, we deploy a targeted arsenal of equipment. This includes Low-Grain Refrigerant (LGR) dehumidifiers and high-velocity air movers designed to create a powerful drying vortex. This aggressive drying is monitored daily with moisture meters until we can document that the structural materials have reached their pre-loss dry standard. This step is vital for preventing mould from returning.
Post-Remediation Verification (PRV)
Once the structure is verifiably dry, a final inspection confirms the successful removal of all visible contamination. For significant projects, particularly those involving vulnerable occupants or complex insurance claims, we recommend and can coordinate independent clearance testing by a third-party environmental professional to provide ultimate peace of mind.
The Health Risks of Post-Flood Mould in Lismore Homes
The stagnant floodwaters that sat in Lismore properties created an incubator for a host of mould species. Common indoor moulds like Aspergillus and Penicillium, known allergens that can trigger severe respiratory issues, established themselves rapidly. For many homes in low-lying areas of the Lismore CBD, South Lismore, and North Lismore, prolonged saturation of cellulose-based materials like timber and gyprock created conditions for toxigenic moulds such as Stachybotrys chartarum (black mould) to grow.
Exposure to these elevated spore loads can cause a range of health issues, from persistent coughing and wheezing to more severe reactions in individuals with asthma, allergies, or compromised immune systems. Ignoring a mould problem doesn’t make it go away; it allows the hyphal networks to further degrade building materials, leading to irreversible structural decay and a musty odour that permeates everything. Taking swift, professional action is the only way to safeguard your family’s health and the structural integrity of your property.

Frequently Asked Questions About Post-Flood Mould
It is a systematic process guided by the IICRC S520 standard. It includes a detailed inspection, establishing containment to prevent cross-contamination, physically removing mould-damaged materials, decontaminating the remaining structure, and using industrial dehumidifiers and air movers to ensure the building is returned to a safe, dry state.
For a room with contained mould, it might take a few days. For a property that was fully inundated in the Lismore flood, the process will take significantly longer. This involves extensive materials removal and a multi-day, or even multi-week, structural drying phase that cannot be rushed.
Our primary method is physical removal of the source. This is non-negotiable. We support this with HEPA-filtration air scrubbing to capture airborne spores and the targeted use of appropriate antimicrobial treatments on salvageable structural elements.
By physically removing the mould colonies that produce spores and mycotoxins, we eliminate the source of the problem. Running commercial-grade HEPA air scrubbers throughout the process captures airborne particulates. Finally, correcting the moisture problem ensures the mould does not return, providing a long-term improvement in the indoor environment.
Our technicians use full personal protective equipment (PPE), including P2/N95-rated respirators, gloves, and disposable coveralls. The most critical safety measure for your family is our use of physical containment and negative air pressure, which isolates the work area and prevents the spread of contaminants to safe zones within your property.
