Trusted Biohazard Remediation in Sydney for Every Suburb
Sydney homes and businesses face a unique combination of challenges — from coastal humidity accelerating mould growth to older plumbing systems that increase the chance of leaks and sewage backflow. High-density living also means contamination spreads faster and affects more people. On Guard Sanitation Services provides a fast and reliable response across all key regions, including the Inner West, Eastern Suburbs, Northern Beaches, North Shore, Western Sydney, and the CBD.
Understanding the layout, building styles, moisture patterns, and airflow issues common in Sydney properties allows the team to diagnose and treat contamination more precisely. This local insight ensures your remediation is not only thorough but tailored to Sydney’s environmental conditions and property types.

Specialised Biohazard remediation process
Mould + Environmental Remediation
Mould commonly develops when moisture lingers inside walls, floors or cavities, or when indoor air becomes stagnant and humid. Our team restores safe indoor conditions by treating contamination at the source — not just the surface.
Service includes:
- Moisture mapping & leak detection
- HEPA H-class vacuuming
- DF200 antimicrobial treatment
- Hot water extraction
- Structural drying
- Optional pre- & post-testing
Emergency Water + Flood Damage Restoration
Flooding spreads rapidly and may cause long-term structural damage if not managed correctly. We act quickly to extract water, stabilise the property and minimise the risk of mould growth or material deterioration.
Service includes:
- Immediate water extraction
- Removal of affected contents
- Moisture testing of all materials
- DF200 decontamination (Cat 1, 2, 3)
- Structural drying installation
- Containment & air scrubbers
Biohazard Remediation
Biohazard events require controlled procedures to protect health and prevent secondary contamination. We restore affected spaces safely and compliantly while managing all environmental and WHS risks.
Service includes:
- Risk assessment & zoning
- DF200 treatment of surfaces
- Containment setup
- HEPA air scrubbing
- EPA-accredited waste disposal
- Laboratory testing, if required
Forensic & Trauma Cleaning
Trauma and forensic scenes must be handled with dignity, privacy and technical precision. Our team manages the cleanup discreetly and respectfully, supporting property owners, families and emergency services throughout the process.

Service includes:

- Sorting & categorising items
- Clear client direction on what stays or goes
- Packing, disposal, donation & storage coordination

Containment & Risk Mitigation
Proper containment prevents contaminated particles or moisture from spreading into unaffected parts of a property. Our tailored setups create safe work zones that support controlled, compliant remediation.
Service includes:
- Physical containment barriers
- Controlled access pathways
- HEPA air scrubbers inside containment
- Secondary scrubbers outside containment
- Cross-contamination prevention in sensitive sites
Fire, Smoke & Odour Remediation
Fire and smoke leave behind soot, odours and residues that may persist without proper treatment. We remove contamination thoroughly and restore air quality to help the property return to a habitable condition.
Service includes:
- HEPA vacuuming of soot & ash
- One-pass soot sponge cleaning

Other Services Offered
Covid-19 and Infection Control Cleaning
Infectious pathogens may pose serious risks and are often invisible. On-Guard Sanitisation provides high-standard biohazard and communicable disease cleaning with rapid emergency response, available 24/7. Our team disinfects contaminated environments thoroughly so you may return focus to your family or business.
Vehicle and Boat Biohazard Remediation
Biohazard contamination in vehicles or boats requires more than surface cleaning. We use thorough chemical treatments to remove pathogens, odours, and affected porous materials after incidents like deaths, disease outbreaks, or bodily fluid spills. On-Guard Sanitisation travels to your location to safely remediate all hazards.
Blood Cleaning
Our specialists are trained to remove and dispose of biohazardous blood and infectious materials safely. All waste is handled via licenced medical transporters. We use full protective gear to avoid exposure to dangerous pathogens and provide reliable 24/7 support for urgent blood cleanup.
Sharps & Needles Clearance
Improperly handling mould may worsen contamination and spread spores. Professional remediation is essential for restoring air quality and removing visible and airborne mould. On-Guard Sanitisation offers fast, effective mould removal for affected properties so issues don’t escalate or return.
Emergency Vehicle Cleaning
Emergency vehicles with biohazard exposure require deep chemical disinfection, often including removal of contaminated materials. Whether caused by medical events or disease outbreaks, we thoroughly decontaminate all affected areas.
Industrial Accidents
Biohazard incidents at workplaces may be disruptive and distressing. On-Guard Sanitisation provides rapid response cleanup for blood spills, machinery contamination, and industrial accidents. We follow strict safety protocols, including lock-out/tag-out procedures, helping businesses stay compliant while reducing downtime.

Frequently Asked Questions
Where in NSW do you provide remediation services?
On Guard Sanitation biohazard remediation services operate across New South Wales, supporting residential, commercial, industrial, healthcare and government sites. Response times vary by location and urgency, and priority is given to high-risk and emergency situations.
Is testing always required after remediation?
Not always. Testing is often used for mould, meth residue and some biohazard scenarios, particularly where third-party clearance is required by insurers, property managers or environmental hygienists. In other cases, visual inspection, moisture readings and process documentation may be sufficient.
How do you decide whether materials are cleaned or removed?
Decisions are based on moisture readings, duration of exposure, the category of water (IICRC Cat 1, 2 or 3), structural condition and the extent of contamination. Where safe remediation is not possible or cost-effective, we may recommend removal and replacement.
Is it safe for occupants to remain on site during remediation?
This depends on the type and severity of contamination. In some cases, containment and zoning allow partial occupancy. In others — particularly heavy biohazard, fire or sewage events — temporary relocation may be safer. This is always discussed openly with owners, managers and, where relevant, insurers.
How quickly should we act after a water or sewage incident?
The sooner the better. Mould often starts developing after roughly three days in wet building materials. Rapid extraction, decontamination and structural drying help reduce health risks, further damage and cost.
