When someone passes away alone and their body remains undiscovered for an extended period, the aftermath presents serious challenges that go far beyond ordinary cleaning. An unattended death occurs when someone passes away and is not discovered for days, weeks, or even months. The longer the time, the more extensive the cleanup becomes. We understand this is one of the most difficult situations a family or property owner can face, which is why we've created this guide to help you understand what's involved and why professional help is essential.
The decomposition process begins within minutes of death. Many families facing this situation ask how long before a dead body starts to smell. Within 24 to 72 hours, strong odours and visible biohazard risks such as bodily fluids typically appear. The human body undergoes rapid changes that create hazardous conditions requiring specialist equipment and expertise to address safely.
Decomposition produces more than 400 chemical compounds, including cadaverine and putrescine, which are responsible for the powerful and lingering odour. These compounds penetrate porous materials like carpets, furniture, and even structural elements of a building. In warm conditions, decomposition accelerates dramatically, making summer unattended deaths significantly more challenging to remediate.

Many people assume that emergency services handle cleanup after they've removed the body. They don't. Families are often surprised to learn that emergency services do not handle cleanup. The responsibility lies with property owners or relatives to hire trained biohazard specialists who understand how to clean up bodily fluid spills safely and effectively.
Attempting death cleaning yourself exposes you to serious health risks. Bodily fluids can contain bloodborne pathogens including HIV, hepatitis B, and hepatitis C. Cleanup is not just about removing visible traces. Pathogens can remain infectious in bodily fluids for days, making professional sanitisation essential for safety. The physical aftermath involves harmful bacteria and other bodily fluids that require proper disposal according to health and safety regulations.
Professional unattended death cleanup services have specialist equipment, proper training, and experience to handle trauma scene cleanup safely. We use personal protective equipment (PPE), industrial-grade cleaning agents, and follow strict safety protocols to protect ourselves and ensure the property is safe for future occupancy.
An unattended death scene poses immediate threats to anyone who enters. Decomposing bodies release fluids containing harmful pathogens. These fluids seep into flooring, carpets, and subflooring. In many cases, entire sections of flooring or furniture must be removed and safely disposed of. Questions such as can you get hep c from dried blood highlight just how dangerous even trace contamination can be.
The contaminated materials harbour harmful bacteria that can cause respiratory problems and other health issues. The immediate environment becomes a biohazard that requires proper handling. Trained professionals understand how to prevent cross contamination and protect themselves whilst working in such situations safely.
Beyond the biological hazards, the emotional toll on family members attempting this work themselves can be deeply distressing. The trauma scene often contains reminders of their loved one that make the cleanup process unbearable for those close to the deceased.
When we arrive at an unattended death cleaning job, we follow a systematic approach. Families often ask who cleans up after a death, and the answer is that only trained specialists can safely manage the risks involved. On average, unattended death cleanups take from 6 hours to several days, depending on the extent of contamination and size of the property.
First, we assess the affected area to determine the extent of contamination. We identify all surfaces and materials that have been compromised, including hidden areas where decomposition fluids may have spread.
We then isolate the crime scene or trauma scene to prevent contamination of other areas. Using personal protective equipment (PPE), our specialist cleaners remove all contaminated materials. This often includes carpets, furniture, and even sections of flooring or drywall that cannot be adequately sanitised.
The thorough cleaning process involves multiple stages. We use enzyme-based cleaning agents specifically designed to break down biological matter. These products eliminate lingering odours at the molecular level rather than simply masking them. We also deploy air scrubbers and ozone treatments to purify the air and remove any remaining odour molecules.
After the initial cleaning, we sanitise all surfaces multiple times using hospital-grade disinfectants. We perform ATP testing to verify that all biological contamination has been eliminated. This scientific testing confirms the property is safe before we consider the work complete.
All hazardous waste and biological waste must undergo proper disposal according to environmental and safety regulations. We have the licences and knowledge to handle this aspect correctly, preventing legal issues for property owners.

The time required varies significantly based on several factors. If the body remains undiscovered for only a few days, the cleanup may take 6 to 12 hours. However, when someone has been left unattended for weeks or months, restoration can take several days.
Temperature plays a significant role. In severe cases, restoration can involve not only cleaning but also replacing carpets, furniture, drywall, and subflooring to eliminate contamination. Summer deaths in warm climates present the most challenging scenarios.
The size of the property and the location where the death occurred also affect the timeline. A death in a small bathroom is typically easier to address than one that occurred in a living room with extensive carpeting and furniture.
Property owners have specific landlord responsibilities when an unattended death occurs in their rental property. You must ensure the property is safe and habitable before allowing new tenants to move in. This isn't just about appearances. Health and safety regulations require proper remediation of any biohazard situation.
Insurance may cover some costs associated with unattended death cleanup, but policies vary. Contact your insurer early in the process to understand what's covered. Many landlord insurance policies include some provision for trauma cleaning or biohazard remediation.
Even if you're not required to hire professional cleaning services by law, attempting the work yourself could create liability if you don't eliminate all health hazards. Professional companies carry insurance that protects both them and you during the cleanup process.
Standard house cleaning or even tenancy cleaning services are not equipped to handle unattended death scenes. The work involved requires specialist training, equipment, and certifications that ordinary cleaning companies don't possess.
Professional unattended death cleanup teams have expertise in:
Identifying all areas of contamination, including hidden seepage into structural elements. Safely removing and disposing of biohazardous materials according to regulations. Using appropriate personal protective equipment to prevent exposure to bloodborne pathogens. Applying specialised cleaning agents that break down biological matter. Conducting verification testing to confirm all contamination has been eliminated. Following health and safety protocols designed for crime scene cleaning and trauma scene situations.

The temptation to save money by handling the cleanup yourself is understandable, but the risks outweigh any potential savings. Without proper training, you could expose yourself to serious health risks including HIV, hepatitis B, hepatitis C, and various other infections present in decomposition fluids.
You also lack the equipment needed to do the job properly. Air scrubbers, ozone generators, ATP testing devices, and industrial-grade biohazard cleaning agents aren't available at your local hardware store. Seeking professional help ensures the work is done correctly the first time.
The psychological impact of cleaning up after a loved one or even a tenant can be deeply distressing. Many people who attempt this work experience lasting trauma from the experience.
