Unattended death cleanup

What this involves

When a death goes undiscovered for days, the body's fluids move into the materials beneath and around it, and odor travels through the air into fabrics, drywall and the HVAC system. The affected area usually reaches well past what is visible: into subflooring, wall cavities and adjacent rooms. Odor that returns after a surface cleaning almost always means contaminated material was left in place.

Why professional remediation matters

Decomposition fluids carry the same bloodborne pathogen risks as blood, plus bacteria that thrive in the conditions involved. Fully removing them often requires taking out flooring and subfloor sections, and the odor problem needs a source-removal approach rather than fragrances or ozone alone. For families, there is also the simple fact that this is not work anyone should have to do for someone they loved.

What to avoid before help arrives

• Do not enter the room again once the person has been removed, unless you need to retrieve something urgent. If you must, wear gloves and do not touch affected surfaces.
• Do not run fans or the HVAC system in an attempt to clear odor. It moves odor and contaminants into other rooms.
• Do not try to mask odor with candles, sprays or air fresheners.
• Do not remove furniture or belongings from the room before they have been assessed.

How the work is done

1. Release confirmation. We confirm the scene has been released by law enforcement or the medical examiner before work begins.
2. Assessment. We trace where fluids traveled, including under flooring and through wall bases, and identify belongings that can be cleaned and returned.
3. Contents. Personal items the family wants to keep are separated, cleaned where possible, and set aside. Nothing personal is discarded without your say.
4. Source removal. Contaminated flooring, subfloor and drywall sections are removed and packaged.
5. Disinfection and odor control. Remaining structure is cleaned and disinfected. Odor is addressed at its source, then with air filtration and, where needed, sealing of treated surfaces.
6. Final check. The space is inspected for remaining odor and visible contamination before hand-back.

Waste handling

Materials saturated with bodily fluids are handled as regulated medical waste. Lightly affected materials may qualify for ordinary disposal; we explain which is which.

Afterward

Most rooms need some rebuilding afterward: subfloor, flooring and sometimes drywall. Landlords should plan for this before the unit can be re-let.
