Sensitive, Thorough Cleanup When Health and Property Risks Are Severe
Decomposition can affect flooring, subfloors, drywall, furniture, and surrounding materials in a short period of time. The longer contamination remains in place, the more difficult and expensive the cleanup becomes. Our team uses professional protective equipment, advanced disinfectants, odor control methods, and proven remediation techniques to clean the area safely and stabilize the property.
Whether the loss occurred in a home, apartment, hotel room, office, or other occupied structure, we act quickly to reduce health risks and prepare the site for further restoration. Our goal is simple: remove contaminated materials, sanitize the space, and help restore safe conditions with compassion and professionalism.

How is an unattended death cleaned up safely?
After the coroner's office releases the home, a trained crew removes contaminated flooring, subfloor and furnishings, cleans and disinfects what remains, treats odor at its source, and disposes of waste under OSHA and Illinois rules. Families should not attempt this themselves: OSHA treats body fluids and human tissue as potentially infectious, and odor often sits below the surface.
What should families do first?
Call 911 or the non-emergency police line first. In DuPage County, the Coroner's Office family information page explains that for a death at home without hospice care, the coroner's office is contacted and asked to respond to the scene. You don't need to arrange cleaning before that visit, and you shouldn't try.
While you wait, a few small steps help. Keep the door to the room closed, keep children and pets away, and avoid moving belongings in the affected area. If you have to go in, don't touch fluids or stained materials.
| Step | Who handles it | What families should know |
|---|---|---|
| Report the death | Family, neighbor or landlord calls police | For a home death without hospice, the coroner's office is asked to respond |
| Investigation | Coroner's office | The circumstances and details of the death are reviewed |
| Personal property | Coroner's investigator | Property taken into custody is logged, secured and available to next of kin during business hours |
| Release to a funeral home | Mortuary and legal next of kin | The body is released after the next of kin signs an authorization, usually provided by the mortuary |
| Cleanup and restoration | Owner, family or landlord arranges it | Begins once the home is released; questions for the coroner go to 630-407-2600 |

A closed door is enough for now
Families sometimes feel they should tidy up before anyone arrives. They shouldn't. Leaving the room closed and untouched protects your health and helps the crew see exactly where contamination has traveled.
Why do odor and fluids reach the subfloor?
Decomposition releases fluids that move downward and outward. On carpet, they pass through the pile into the pad, then into the wood subfloor and the tack strip at the wall. On hard floors, they find seams and grout lines. Drywall wicks fluid up from the bottom edge, and upholstered furniture and mattresses absorb it deeply.
Odor follows the same path. It binds to porous materials, so surface cleaning alone rarely ends it, and air fresheners only mask it for a while. The usual fix is to remove affected materials down to sound structure, clean and disinfect what's left, then seal treated wood before new flooring goes in. That is why the visible stain is often much smaller than the area that must be removed.
Hidden damage under the floor
Once carpet and pad are lifted, the subfloor shows how far fluids spread. Affected sections are cut out or cleaned and sealed, and baseboards and the lower edge of drywall are checked as well.
Why does professional cleanup protect your health?
Under OSHA's Bloodborne Pathogens standard, 29 CFR 1910.1030, "other potentially infectious materials" include unfixed human tissue from a living or deceased person and all body fluids in situations where it is difficult to tell them apart. Workers handle these under universal precautions, wearing protective equipment that keeps fluids off skin, eyes and clothing.
The standard also requires contaminated waste to go into closable, leak-resistant, labeled containers and to be disposed of under federal, state and local rules. See our hazardous waste disposal page for how that works in Illinois. The ANSI/IICRC S540 standard, described on our biohazard cleanup overview, sets the industry process.
- Release and walk-through. After the coroner's office is finished, the crew traces where fluids and odor have spread, including under flooring and into adjoining rooms.
- Protect the rest of the home. The room is sealed off and air handling is managed so odor and contamination don't travel through ductwork.
- Remove affected materials. Mattresses, upholstery, carpet, pad and affected subfloor or drywall are removed and packaged as regulated waste.
- Clean and disinfect. Remaining surfaces are cleaned, then disinfected with an EPA-registered product for its full label contact time.
- Treat odor and seal. Odor is treated at its source, and cleaned framing or subfloor may be sealed before rebuilding.
- Restore. New flooring, drywall and paint follow once the space is confirmed clean.
Keeping what matters
Photos, papers and keepsakes outside the affected area can usually be set aside for the family. Items that absorbed fluids generally can't be saved, and a good crew will explain why before anything leaves the home.
Does insurance cover unattended death cleanup?
Sometimes. A homeowners or landlord policy may respond depending on its terms and the cause of loss, but policies vary. Read the policy, call the insurer, and check the Illinois Department of Insurance if you have questions about your rights. Our insurance claim assistance page explains how we help document the loss; we don't act as a public adjuster.
If the death happened in a rental or condo
In apartments, condos and senior housing, the landlord or association usually has a stake too. Their building policy may cover shared structure such as subfloors and walls, while the family or estate handles personal belongings. Odor can also travel to neighboring units through shared walls and ductwork, so it helps to bring the building manager in early and agree on who is arranging the work. Ask everyone involved to share one written scope so nothing is missed or paid for twice.

Frequently asked questions
Who is responsible for cleanup after an unattended death?
Cleanup is arranged by the property owner, family, estate or landlord once the coroner's office has finished its work. The DuPage County Coroner's family information page explains how the body is released to a mortuary and how personal property is returned, but it does not describe cleaning the scene, so families should plan for that separately.
Can belongings be saved after an unattended death?
Items in other rooms can usually be saved, and keepsakes like photos and papers are often set aside early. Porous items that absorbed fluids, such as mattresses, upholstered furniture and carpet, generally cannot be safely cleaned. OSHA treats items that could release potentially infectious materials as regulated waste that must be packaged for disposal.
Why does the odor come back after the room was cleaned?
Odor binds to porous materials that are hard to see, such as the carpet pad, subfloor, tack strip and the bottom edge of drywall. If those stay in place, surface cleaning and air fresheners only mask the smell for a while. Removing affected materials, disinfecting and then sealing treated wood is what usually ends it.
How do I get personal property back from the DuPage County Coroner?
According to the DuPage County Coroner's family information page, property the investigator takes into custody is logged, secured and made available for release to the next of kin during normal business hours. Call the Coroner's Office at 630-407-2600 with questions about timing or what you need to bring.
Do I need to be at the home during the cleanup?
No. Many families prefer not to be there. After an initial walk-through, you can agree on access, which items to set aside and how you want to be updated. If you do want to be present, you can stay outside the sealed work area while the crew removes materials and disinfects.
