24/7 Emergency Response
Serving the North Coast of NSW
We provide specialist contamination cleanup for residential, rural, and commercial properties across the North Coast of New South Wales. Our IICRC-certified technicians are on call 24/7 for time-critical contamination events, including sewage back-flow, riverine floodwater intrusion, and biohazardous spills. An event involving contaminated water, known as Category 3 or “black water,” presents immediate structural and health hazards that standard cleaning cannot resolve. These situations demand a documented, science-based approach to remediation to ensure your property is returned to a safe, verifiably clean, and structurally sound condition.
Our work is grounded in the specific challenges of the North Coast environment. We manage the aftermath of catastrophic riverine floods that overwhelm entire towns like Lismore, as well as flash flooding that inundates coastal communities from Tweed Heads to Coffs Harbour. The record-breaking February 2022 flood, which saw the Wilsons River peak at 14.4 meters in Lismore, was a defining event for our region. It highlighted the devastating reality of flood risk and the specific contaminants we manage, including thick sediment, agricultural runoff from surrounding farms, and widespread sewage system failure. Our team documented the damage patterns and has since refined our protocols for these complex scenarios, ensuring all hazardous materials are contained and removed according to IICRC and Australian standards
The Immediate Health Risks of Contaminated Flood & Sewage Water
Water from a sewage backup, an overflowing river, or a stormwater drain is a toxic slurry of bacteria, viruses, parasites, and chemical wastes that poses a significant health threat. Exposure to pathogens like E. coli, Salmonella, and Giardia can cause severe illness, while the water may also carry pesticides, herbicides, and industrial chemicals washed from the landscape. These microorganisms and chemicals can become airborne, posing a risk even without direct contact.
Contaminants are readily absorbed by porous building materials. Plasterboard, timber framing common in Queenslanders and modern builds, insulation, and carpet all act like sponges, creating an ideal breeding ground for aggressive microbial growth in our humid subtropical climate. Without immediate professional intervention that follows the AS/IICRC S520 standard, a contamination event will lead to extensive structural mould, persistent odours, and an environment that is unsafe for your family, employees, or tenants. Our primary directive is to contain the hazard, remove all compromised materials, and execute a multi-step decontamination and drying process that makes your indoor environment safe again.
Our Documented Contamination Cleanup Protocol
Initial Safety Assessment & Hazard Mapping
Our first action on-site is establishing a safe perimeter and conducting a thorough risk assessment. Technicians use FLIR E8-XT thermal imaging cameras and Tramex ME5 non-invasive moisture meters to map the full extent of water migration. This is critical for identifying hidden moisture in wall cavities, subfloors of elevated homes, and ceiling spaces, a common issue after water drives sideways during severe storms. This data provides the blueprint for our remediation plan and the core documentation for your insurance claim with providers like NRMA, GIO, or Suncorp.
Hazard Containment & Negative Air Pressure
The contaminated zone is immediately isolated from unaffected areas of the property using 6-mil polyethylene sheeting and containment barriers. We then establish negative air pressure using HEPA-filtered air scrubbers, such as the Thorair Hulk 1000CFM. This crucial step prevents aerosolized contaminants, mould spores, and bacteria from escaping the work area during the removal of damaged materials, protecting the health of occupants in the rest of the building.
Contaminated Material Removal & Water Extraction
All physical contaminants, including flood mud, silt, sewage, and debris, are removed and bagged. We deploy truck-mounted and portable extraction units to remove gross standing water. Porous and semi-porous building materials directly impacted by Category 3 water, such as plasterboard, carpets, and most types of insulation, are unsalvageable. Following IICRC standards, these are carefully cut out, bagged, and disposed of according to NSW EPA guidelines.
Cleaning & Antimicrobial Treatment
After the removal of contaminated materials, all remaining structural surfaces, like timber frames and concrete slabs, are meticulously cleaned. Following cleaning, we apply an EPA-registered, hospital-grade antimicrobial disinfectant. This step is critical for eliminating pathogenic organisms that have penetrated surfaces, a vital stage in preventing future mould growth in the high-humidity North Coast climate.
Structural Drying & Verification
We install a balanced drying system using an array of low-grain refrigerant (LGR) dehumidifiers from trusted brands like Phoenix and BlueDri, alongside high-velocity Dri-Eaz and XPOWER air movers. Our technicians, led by an IICRC-certified supervisor like [Technician's Name], monitor temperature, humidity, and material moisture content daily. Equipment is adjusted to achieve the documented drying goals for the specific materials in your home, whether it's Ironbark framing or radiata pine. The job is not finished until our moisture meters verify the structure has returned to its pre-loss dry standard, a critical step to prevent hidden mould outbreaks weeks or months later.
Specialised Contamination Cleanup for North Coast Properties
We provide targeted solutions for the contamination scenarios most frequently affecting homes and businesses from Byron Bay to Port Macquarie.
Sewage Cleanup (Category 3 Black Water)
A blocked drain, a failed septic system on a rural property, or a municipal sewer main failure during a flood can force raw sewage back into a building. This represents the most hazardous form of water intrusion. Our team adheres strictly to the protocols in the IICRC S520 standard for these events. We perform a complete strip-out of all contaminated porous materials, apply registered biocides, and execute a controlled structural drying process to prevent secondary damage and microbial amplification. We have direct experience managing sewage backups in Lismore’s flood-damaged infrastructure and in coastal homes where aging pipes have failed.
Biohazard and Chemical Spill Neutralisation
Riverine flooding from the Richmond, Wilsons, or Tweed rivers carries a complex mix of contaminants. The water that inundated Lismore in 2022 was not just river water; it was a Category 3 contamination event carrying soil, sewage, chemicals, and decaying organic matter. Runoff from agricultural land can introduce high levels of nitrates and pesticides. Our process for these events involves the removal of several inches of silt and mud, pressure washing of hard surfaces, and a full-scale IICRC S500 water damage restoration and drying protocol on the remaining structure. This ensures the unique contaminants from our regional river systems are properly remediated.
Our IICRC-Certified Technicians and Restoration Technology
Our team’s expertise is our most important asset. Every lead technician on your property holds current certification from the Institute of Inspection, Cleaning and Restoration Certification (IICRC), the global body that sets the standards for our industry. We strictly adhere to the ANSI/IICRC S500 Standard for Professional Water Damage Restoration and the AS/IICRC S520 Standard for Professional Mould Remediation. This commitment means we follow a documented, scientific process that is accepted by all major Australian insurance companies.

Frequently Asked Questions: Contamination Cleanup
Contaminated water, or Category 3 “black water,” is grossly unsanitary and contains pathogenic agents. Sources include sewage backflow, rising river water from events like the Lismore floods, and stormwater that has mixed with ground contaminants like agricultural runoff. It requires professional remediation and should never be handled without appropriate Personal Protective Equipment (PPE).
Yes. Black water from local flood events contains a mix of dangerous bacteria, viruses, and parasites that can cause serious illness. The Richmond River system, for example, is known to carry high sediment loads and runoff from agricultural land. The indoor air quality is also compromised, posing a respiratory risk.
Cleanup must begin immediately. In the humid, subtropical climate of the North Coast, mould can begin to grow within 24-48 hours. The longer contaminated materials sit in the property, the greater the risk of pathogen amplification and irreversible damage to timber frames and other structural components.
The timeline depends on the scale of the damage. A minor sewage overflow in a bathroom might take 2-4 days for removal, drying, and sanitisation. A major flood affecting the ground floor of a Lismore home could take a week or more, involving significant demolition and an extended structural drying period. We provide a detailed project timeline and scope of works after our initial on-site assessment.
Yes, this is the explicit goal. By strictly following the AS/IICRC S520 standard, we remove the source contaminants, the affected materials, and the moisture that fuels microbial growth. This process, verified with moisture meters and, when necessary, third-party post-remediation testing, eliminates hazardous pathogens and prevents the establishment of a hidden mould reservoir, ensuring the property is returned to a safe and healthy state.
