TL;DR: When an unattended death is discovered, law enforcement responds first, then the medical examiner’s office takes over. Once authorities release the scene, a licensed biohazard remediation company handles cleanup, not the family, not a general cleaning crew. Most homeowners insurance policies cover unattended death cleanup under the dwelling or additional coverages section. The process is discreet, handled with protective equipment, and typically completed within one to three days depending on the extent of decomposition.
If you’ve just discovered that a loved one passed away alone, possibly days or weeks ago, you are likely managing grief, shock, and a set of logistical questions you never expected to face at once. This guide walks through what happens next, in order, so you know what to expect and what decisions are actually yours to make.
Who do you call first after discovering an unattended death?
Call 911 immediately. Do not enter the space beyond what is necessary to confirm the situation. Law enforcement must respond first, even when the death appears to be from natural causes, an unattended death is treated as an unattended death until the medical examiner or coroner determines otherwise.
Once law enforcement arrives, they will secure the scene and contact the medical examiner’s office. The medical examiner (or coroner, depending on the county) will determine the cause and manner of death. In Washington State, this process is governed by RCW 68.50, which requires the coroner or medical examiner to investigate any death that occurs without a physician present. The body will be transported to the medical examiner’s facility. This typically happens within hours of the initial call, though the timeline varies by jurisdiction and caseload.
During this phase, the scene remains under law enforcement authority. Family members should not attempt to clean, remove, or disturb anything in the space.
When can the family or a cleanup company enter the scene?
A cleanup company can enter only after law enforcement formally releases the scene. This release is typically communicated verbally and sometimes in writing. Ask the responding officer directly: “Has the scene been released?” Once it has, the space is no longer a law enforcement matter, it becomes a property remediation situation.
At that point, the family has two responsibilities: notify their insurance carrier and contact a licensed biohazard remediation company. The order matters. Calling the insurance carrier first, before cleanup begins, protects the claim. Most homeowners policies require the insurer to be notified before remediation starts, or they may dispute coverage later. Our post on does homeowners insurance cover biohazard cleanup covers the coverage mechanics in detail.
Do not attempt to clean the space yourself, and do not hire a general cleaning service. Decomposition involves biological hazards, bloodborne pathogens, bacteria, and in some cases insect activity, that require specific training, EPA-registered disinfectants, and proper disposal protocols under OSHA’s Bloodborne Pathogens Standard (29 CFR 1910.1030). A general cleaning crew is neither trained nor equipped for this work, and attempting it without proper PPE creates serious health risk.
What does professional unattended death cleanup actually involve?
Professional remediation of an unattended death scene follows a structured process. The scope depends heavily on how long the person was deceased before discovery, decomposition accelerates significantly after 48 to 72 hours and can affect flooring, subfloor, drywall, and HVAC systems in more extended cases.
A qualified crew will:
- Assess the full extent of contamination. This includes visible surfaces and hidden areas, under flooring, inside wall cavities, in adjacent ductwork. Decomposition fluids migrate further than they appear to on the surface.
- Establish containment. Poly sheeting and negative air pressure prevent cross-contamination to unaffected areas of the home.
- Remove and dispose of contaminated materials. Porous materials, carpet, padding, drywall, insulation, that have absorbed biological material cannot be cleaned; they must be removed and disposed of as regulated biohazardous waste.
- Clean and disinfect all affected hard surfaces using EPA-registered hospital-grade disinfectants. This is not a single pass, it is a multi-step process.
- Deodorize the space. Decomposition odor is caused by specific volatile organic compounds. Hydroxyl generators and thermal fogging are used to neutralize the odor at the molecular level, not just mask it. If the HVAC system was running during the period of decomposition, ductwork may require separate treatment.
- Verify clearance. ATP testing (adenosine triphosphate bioluminescence testing) is used to confirm that biological contamination has been reduced to safe levels before the space is considered remediated.
For most situations involving a discovery within a few days, remediation takes one to two days. Cases involving extended decomposition, a week or more, may require two to four days and more extensive structural material removal, followed by reconstruction work.
How much does unattended death cleanup cost, and does insurance cover it?
Unattended death cleanup typically costs between $3,000 and $25,000 depending on the size of the affected area, the duration of decomposition, and whether structural materials need replacement. Extended cases in larger homes can exceed that range when subfloor replacement, drywall removal, and reconstruction are involved.
Most standard homeowners insurance policies do cover unattended death cleanup. Coverage is typically found under the dwelling coverage (Coverage A) for structural damage, and sometimes under a specific “biohazard remediation” or “trauma scene cleanup” endorsement. Some policies include it under additional coverages without a separate endorsement. The key variables are your deductible, your policy’s coverage limits, and whether the insurer requires their preferred vendor or allows you to choose your own.
A licensed remediation company will document the scope of work, photograph the affected areas before and after, and provide a written estimate, all of which your insurance adjuster will need. Choosing a company that understands the insurance documentation process makes the claim significantly smoother.

What should a family expect from the remediation company?
A professional biohazard remediation company should handle this work with complete discretion. Crews arrive in unmarked or low-profile vehicles. There are no large branded signs on the property. The team understands that neighbors may not know what occurred, and they conduct themselves accordingly.
You should expect:
- A calm, clear explanation of the scope before any work begins
- A written estimate tied to what your insurance carrier will need
- Direct communication with your adjuster if you want it
- Workers in full PPE, Tyvek suits, respirators, double-glove protocol, throughout the process
- No family member should feel pressured to observe or be present during the work itself
Family members are not required to be on-site during remediation. Many choose to leave the property entirely and receive a call when the work is complete and the space has been cleared.
If reconstruction is needed after materials are removed, new flooring, drywall, paint, a company that handles both remediation and reconstruction can complete the entire scope without the family coordinating multiple contractors during an already difficult time.
