Families & executors
Compassionate, discreet cleaning after an unattended death or trauma event.
Trauma, unattended death, biohazard and severe hoarding situations require a level of care, discretion and compliance that general cleaning cannot provide. Delta Environmental handles these situations with compassion and strict safety protocols.

Also known as biohazard cleanup, crime scene cleaning or trauma cleaning, biohazard and forensic cleaning covers situations that go well beyond general cleaning: unattended deaths, trauma and accident scenes, blood and bodily fluid exposure, severe hoarding, infectious disease decontamination and other biohazard events. These situations carry genuine health risks from bloodborne pathogens and biological contamination, alongside significant emotional weight for the families, landlords or businesses involved.
Delta Environmental provides discreet, compassionate biohazard and forensic cleaning across Australia, coordinating where appropriate with police, coroners, real estate agents and family members. Our technicians follow strict infection control protocols, use appropriate personal protective equipment, and dispose of biohazardous waste through licensed biomedical waste contractors in line with state environmental regulations.
We understand these calls often come at the worst possible time. Our teams arrive in unmarked vehicles, work efficiently and respectfully, and aim to restore the property to a safe, liveable condition without adding further distress to an already difficult situation.
We also work regularly with real estate agents and executors who need a property returned to a presentable, saleable condition after a difficult event, and can coordinate the cleaning around probate timelines, family visits or an upcoming open for inspection without compromising on safety or thoroughness.
These are the situations most commonly requiring professional biohazard or forensic cleaning in Australia.
We assess the scene and scope the work with sensitivity and discretion.
The area is contained and technicians work in full protective equipment.
Contaminated materials are removed and all surfaces are disinfected.
Where needed, we treat lingering odour at its source.
All biohazard waste is disposed of through licensed biomedical waste contractors.
A technician assesses the extent of contamination and any structural or material damage, coordinating where relevant with police, coroners or property managers before work begins.
We understand families and landlords are often dealing with grief or shock alongside the practical cleanup, and we act accordingly.
Unmarked vehicles and plain-clothed technicians protect the privacy of everyone involved.
Technicians follow rigorous protocols to manage bloodborne pathogen and biological contamination risk.
Biohazard waste is handled as clinical and related waste and disposed of through licensed contractors, not general rubbish collection.
Attempting to clean a biohazard scene without the right protective equipment, disinfectants and disposal process carries real health risk. It is not something families, landlords or general cleaners should be expected to handle alone.
Booking biohazard & forensic cleaning with an unfamiliar company can feel like a leap of faith, so we keep our side of the arrangement simple and transparent. You get a clear, itemised scope of works before anything begins, a fixed appointment window rather than a vague all-day slot, and a single point of contact for the life of the job rather than being passed between call centres.
If a job turns out to be larger or more complex once work is underway, we explain why, put any change in writing, and get your sign-off before proceeding. There are no surprise line items on the final invoice.
We quote based on what your property actually needs, not a one-size-fits-all package. If a lighter touch will do the job safely, that is what we will recommend.
Biohazard and forensic cleaning intersects with several regulatory areas in Australia. Bloodborne pathogen and infection control practices reflect the same principles used in healthcare settings, including standard precautions for handling blood and bodily fluids. Waste generated during biohazard cleaning is generally classified as clinical and related waste, which is regulated by each state and territory environmental protection authority and must be transported and disposed of by a licensed biomedical waste contractor.
Where a death or serious incident is involved, cleaning is only carried out once police or coronial investigations have concluded and the scene has been formally released, and we coordinate directly with the relevant authorities, real estate agents or family representatives to manage this respectfully.
Technicians are also trained to recognise and safely manage related hazards commonly found alongside biohazard situations, such as discarded sharps or needles, which require their own careful handling and disposal separate from general biological waste.
Biohazard waste cannot legally go into general household or commercial waste. It must be handled as clinical and related waste and disposed of through a licensed biomedical waste contractor, and we manage this as a standard part of every job.
Biohazard and forensic cleaning costs depend on the nature and extent of contamination.
Extent of contamination. A contained, quickly discovered incident costs less to remediate than an extensive or delayed-discovery situation.
Materials affected. Porous materials such as carpet, underlay and mattresses that cannot be fully disinfected typically require removal and replacement.
Odour severity. Strong or deeply set odour, particularly in flooring and subfloors, may require additional specialised treatment.
Waste volume and disposal. Larger volumes of biohazard waste involve more disposal cost through licensed contractors.

This depends on the situation. For rental properties, landlord insurance or the estate of the deceased may cover costs. For workplace incidents, the business is typically responsible. We can provide a clear quote and documentation to support whoever is arranging payment.
Yes. Where a death or serious incident is involved, we only begin work once the scene has been formally released by police or coronial authorities, and we coordinate directly with them or with the family's representative.
We operate with full discretion, using unmarked vehicles and plain-clothed technicians. Our goal is to restore the property without drawing attention to the situation.
Biohazard waste is classified as clinical and related waste and must be transported and disposed of by a licensed biomedical waste contractor, in line with state environmental regulations. This is included as standard in our process.
Yes. Persistent odour, particularly from fluids that have soaked into flooring or subfloors, is treated at the source using appropriate products and, where needed, removal of affected material, rather than masked with fragrance.
Many landlord and building insurance policies include cover for biohazard or trauma cleaning following a covered incident, though terms vary by insurer. We provide documentation to support a claim.
We treat biohazard call-outs as urgent given the health risks involved and aim to attend as quickly as possible, including outside of standard business hours where the situation requires it.
Yes. Severe hoarding often involves biohazard, pest and structural concerns alongside the volume of belongings, and we approach these jobs with the same discretion and care as other biohazard work, coordinating with family members or support services where appropriate.
This work is generally carried out by specialist biohazard and forensic cleaning companies rather than general cleaners, given the infection control, waste disposal and emotional sensitivity involved. Cleaning only begins once police or coronial authorities have formally released the scene, and technicians follow strict protocols for handling blood and bodily fluids and disposing of contaminated material as clinical waste.
Cost depends on the extent of contamination, whether porous materials like carpet or mattresses need replacing, and how much biohazard waste requires licensed disposal. A contained, quickly discovered situation costs considerably less than an extensive or delayed-discovery one. We provide a free, confidential quote once we understand what the job involves.
