Riverside Bio Clean arranges unattended death cleanup, sometimes called decomposition cleanup, for homes, apartments, mobile homes and vehicles across San Bernardino County and Riverside County, from Fontana and Ontario to San Bernardino, Corona and Moreno Valley. The cleanup company removes contaminated materials, disinfects the affected area, deals with the odor at its source and disposes of the waste as regulated medical waste. Families, executors and landlords use this service after the coroner has finished and the body has been removed.
How the days before discovery change the job
Decomposition starts within hours and moves faster in heat. An Inland Empire summer, a closed apartment and an air conditioner that was switched off can all turn a small job into a large one. The table below is a general guide to how scope usually grows. It is not a diagnosis of any particular home, and every company will want to see the property before it quotes.
| Found within | What is usually affected | Typical scope |
|---|---|---|
| A day or two | Bedding, a chair or a patch of carpet; light odor | Remove the soft items, clean and disinfect hard surfaces, short odor treatment |
| Several days | Fluids through carpet and pad to the subfloor; odor in soft furnishings nearby; flies | Cut out flooring, clean and seal the subfloor, remove nearby furniture, longer odor treatment |
| A week or more | Subfloor, baseboards and lower drywall; odor in the HVAC system and neighboring rooms; insect activity | Structural removal in the affected area, HVAC cleaning, sealing, several days of odor work, sometimes rebuild by a contractor |
Where unattended deaths happen, and what changes
The type of property changes the scope as much as the timing does.
- Houses
- Fluids usually stay in one room, but can reach the subfloor, the crawlspace or slab joints, and the ducts if the air was running.
- Apartments and condos
- Shared floors and walls mean the unit below or next door may need checking, and the HOA or manager will want to know the scope.
- Mobile homes and RVs
- Floors are often thinner and spaces smaller, so fluids and odor reach the structure and the whole unit sooner.
- Cars and trucks
- Seats, carpet and headliners absorb fluids and odor. Ask whether cleaning would cost more than the vehicle is worth.
- Rentals and estates
- Called in by a landlord, a property manager or an executor, often from out of the area, with access arranged by lockbox.
- Homes with pets
- Animals left inside need care first. Pet waste and any damage they caused become part of the cleanup scope.
After the coroner releases the scene
In both counties, deaths at home that are not attended by a doctor are reported to the sheriff-coroner, which investigates, removes the body and later issues the paperwork families need. The coroner does not clean the home. Once the investigators leave, the property is back in the hands of the owner, the family or the landlord, and the cleanup can be booked. The first 24 hours after a death at home guide lists the county coroner offices and the order of calls.
Before the crew arrives, it helps to:
- Keep the door closed and any pets out of the area.
- Leave the heating or air conditioning as it is, unless the company tells you otherwise, so contaminated air is not pushed through the house.
- Take out valuables, documents and medication only if you can reach them without walking through the affected area.
- Photograph the rooms for insurance, from the doorway.
- Tell the company if the person had a known infectious disease, so the crew can plan protection.
How an unattended death cleanup runs
Most jobs follow the same sequence, from the first call to handing the keys back. Ask the company to walk you through its version before you agree.
- First call
- You describe the property, roughly how long it was before the person was found, and the ZIP code. The company asks whether the coroner has finished and how to get in.
- Walk-through
- The company inspects the affected area, or reviews your photos, and gives you a written scope and price. Nothing starts until you agree.
- Containment
- The crew seals the room with plastic sheeting, sets up air filtration if needed, and works in protective equipment so nothing spreads to the rest of the home.
- Removal
- Mattresses, upholstered furniture, carpet, pad and any flooring or drywall that absorbed fluids are cut out, bagged and labeled as regulated waste.
- Cleaning
- Hard surfaces and exposed subfloor are cleaned, then disinfected with an EPA-registered disinfectant, and sealed where odor could linger.
- Odor treatment
- Once the source is gone, hydroxyl or ozone equipment and fogging treat what remains in the air, the ducts and porous surfaces.
- Handover
- You get a walk-through or photos, the disposal paperwork, and a clear note of anything a contractor needs to rebuild, such as new flooring.
Personal items that can be cleaned are set aside for the family rather than thrown away. If there are photographs, papers or keepsakes in the affected room, say so on the first call.
Cost and who pays
Price depends on how long the person lay undiscovered, the size of the affected area, how much flooring or wall has to come out, and how much odor work is needed. The cost of unattended death cleanup guide collects published ranges. Homeowners insurance often responds to this kind of loss; see who pays for crime scene cleanup in California for insurance, victim compensation and deaths in rentals.
When the home is a rental or part of an estate
Landlords, property managers and executors are often the people who make this call, sometimes from out of state. The cleanup company can usually work with a lockbox or a manager on site and send photos and a written scope. The property managers and funeral homes page covers what to have ready and the California rules on a tenant's belongings and future disclosure of the death.
Unattended death cleanup questions
Can we go back into the home before it is cleaned?
You can, but keep it short, avoid the room where the death happened, and do not touch stains, bedding or furniture with bare hands. Body fluids can carry bloodborne pathogens and decomposition gases are unpleasant and irritating. Collect only essentials such as keys, medication, documents and pets.
Will the smell go away once the body is removed?
No. The odor comes from fluids that have soaked into carpet, padding, mattresses, subfloor and sometimes drywall. It stays until those materials are removed and the structure is cleaned and sealed. Air fresheners and open windows only mask it for a while.
Does homeowners insurance cover unattended death cleanup?
Often, at least in part, because the damage is sudden and accidental. Policies differ, so call your insurer or agent before work starts and ask whether the cleanup company can bill them directly. Our guide on who pays in California covers insurance, victim compensation and tenant deaths.
Who is responsible for the cleanup when a tenant dies?
Usually the property owner arranges and pays for the biohazard cleanup of the unit, then deals with the tenant’s estate over belongings and any claim. Insurance may help. Our page for property managers explains the California rules that tend to come up.
How long does the cleanup take?
A contained job, found quickly, can often be finished in a day. A death that went unnoticed for a week or more in warm weather can take several days because flooring, subfloor and sometimes walls have to come out before odor treatment can work. The company will give you an estimate after it sees the property.
