Undiscovered Death Cleanup
Oakland County, Michigan
Decomposition contaminates fast — floors, walls, HVAC. Act immediately. 911 Bio Clean dispatches 24/7 throughout Oakland County.
Quick Answer
What is Undiscovered Death Cleanup?
Undiscovered death cleanup — also called decomposition cleanup or unattended death remediation — is the professional decontamination of a property where a person passed away and was not discovered for an extended period. Decomposition fluids, gases, and biological contamination spread rapidly into subflooring, walls, and HVAC systems and require specialized remediation well beyond standard cleaning. This service is typically covered by homeowners' insurance with most clients paying $0 out of pocket.
Decomposition & Unattended Death Specialists
When a person passes away and is not discovered for days, weeks, or longer, decomposition rapidly contaminates the surrounding environment.
911 Bio Clean has the training, certification, and industrial equipment to safely remediate even the most severe undiscovered death scenes.
Time is critical — the longer you wait, the deeper the contamination spreads. Call us immediately at (810) 228-9282.
Average Response Time: 1–2 Hours
We dispatch immediately upon your call — 24 hours a day, 7 days a week, including holidays.
What's Included
Health Risks — Why Immediate Response Matters
Decomposition Gases
Hydrogen sulfide and other toxic gases are dangerous even in brief exposures.
HVAC Spread
Odors and pathogens circulate through air systems, contaminating the entire property.
Structural Penetration
Decomposition fluids rapidly saturate subflooring, wall cavities, and concrete.
Insect & Pest Activity
Unattended deaths attract flies, beetles, and other insects.
Biohazardous Liquids
Purge fluid carries serious pathogens including Clostridium botulinum.
Mold Growth
Moisture from decomposition creates ideal conditions for rapid mold growth.

What Makes Our Undiscovered Death Cleanup Different
Specific capabilities that set our undiscovered death cleanup service apart in Oakland County.
HVAC Decontamination Included
Decomposition odors enter air ducts within days. We decontaminate the entire HVAC system — vents, ducts, coils — as a standard part of every unattended death job, not an add-on.
Subfloor & Structural Assessment Protocol
We use moisture meters and black-light fluorescence testing to detect contamination below visible surfaces before any material is removed — preventing missed contamination that causes odor to return.
Insect & Larval Remediation Capability
Unattended deaths attract blowflies, carrion beetles, and other insects. We manage insect activity and larval removal as part of our specialized decomposition cleanup process.
Staged Disclosure for Families
We provide damage assessments in stages to families so they don't receive all difficult information at once. Our project coordinator manages all communication with compassion.

Michigan Law & Property Owner Responsibilities
What Oakland County property owners need to know about biohazard cleanup obligations in Michigan.
Who Is Responsible for Cleanup?
In Michigan, law enforcement and first responders do not clean biological contamination. Once investigators release a scene, cleanup responsibility falls entirely on the property owner.
This applies to crimes scenes, suicides, unattended deaths, and all biohazard situations. The Oakland County Sheriff's Office and local police departments will not perform or arrange cleanup.
Landlords are also legally responsible for cleanup in rental properties before allowing new tenants to occupy a unit where a biohazard event occurred.
OSHA & Federal Regulations
OSHA 29 CFR 1910.1030 (Bloodborne Pathogen Standard) requires that anyone handling blood or potentially infectious materials use proper personal protective equipment (PPE) and follow strict exposure control procedures.
Attempting to clean a biohazard scene without proper training, PPE, and certification is not just dangerous — it may violate federal OSHA standards, particularly for landlords, property managers, and employers.
All 911 Bio Clean technicians are trained and certified to comply with OSHA, EPA, and Michigan DEQ regulations.
Michigan Disclosure Requirements
Michigan does not currently require sellers to disclose that a death occurred in a home. However, the Michigan Seller's Disclosure Act requires disclosure of known material defects — which could include structural damage caused by delayed cleanup.
Professional remediation with ATP-clearance documentation protects property owners by providing objective proof that a property was professionally restored to a safe condition. This documentation can be critical if a property is later sold or re-rented.
Biohazardous Waste Disposal in Michigan
Michigan law requires that biohazardous waste — blood-soaked materials, sharps, contaminated structural materials — be collected, transported, and disposed of by a licensed medical waste handler using DOT-compliant red biohazard bags and vehicles.
Placing biohazardous materials in regular trash or dumpsters is illegal in Michigan and can result in fines. 911 Bio Clean handles all regulated waste disposal as part of every job — all materials are transported to a licensed disposal facility.
