Biohazard cleanup: what to know
What the job involves, what changes the price, and what to ask a pro.
What biohazard cleanup is
Biohazard cleanup removes blood, bodily fluids, sewage and other contaminated material from a home or business after a death, injury or other event. It needs trained crews, protective equipment and regulated disposal, and it should never be attempted with household cleaners.
Signs you need it
- Blood, body fluids or sewage have soaked into flooring, drywall, carpet or upholstery
- A death or injury happened in the home and the area still holds contamination
- A sewage backup has reached floors or walls and standing water is present
- A strong odor persists after normal cleaning and you suspect contamination below the surface
- The area is unsafe to enter without protective gear and you are not sure what is present
What the pro does
- Assess the scene from outside the contaminated area and identify what materials are affected
- Set up barriers and work zones so the rest of the home is not contaminated during the work
- Wear full protective equipment and remove contaminated materials such as flooring, padding and drywall as needed
- Clean and disinfect the structure with approved products, then test or inspect the area before closing it
- Bag and dispose of contaminated waste through the regulated disposal process
- Deodorize the space and document the work for the homeowner, the insurer or the property manager
What changes the price
Every job is different, so we do not publish prices. These are the things that move the quote up or down.
- Size of the affected area and how far the contamination has spread
- Materials that must be removed, such as carpet, subfloor, drywall or cabinetry
- Type of contamination, since blood, sewage and other hazards require different steps
- Time since the event, which can increase the work needed
- Access to the scene, including stairs, narrow doorways and the need for containment
- Disposal requirements for the waste generated
What a written quote should spell out
- The scope of removal and the materials that will be taken out and replaced
- The disinfectants and equipment used and the protective measures for the crew and the home
- How waste is packed, transported and disposed of, including the documentation provided
- Whether odor control, air treatment and a clearance inspection are included
- What is not included, such as structural repair, rebuilding or content restoration
Questions to ask before you hire
- Are your crew members trained and certified for biohazard work, and what training do they hold
- How do you contain the work area so the rest of the home is protected
- How do you dispose of the waste, and can you give me the disposal records
- Which materials will you remove, and what do you do with items I want to keep
- Do you test or inspect the area after cleaning and tell me what the result means
- Can you work with my insurer or property manager and provide the paperwork they need
Red flags
- A crew that offers to clean blood or sewage with household products and no protective gear
- No containment plan, which risks spreading contamination to the rest of the home
- Vague answers about waste disposal or no documentation at the end
- Pressure to start the job immediately without an assessment of the scene
What you can do yourself
Do not attempt to clean blood, body fluids or sewage yourself. Keep people and pets out of the affected area, ventilate if it is safe to do so, and call a biohazard professional and your insurer. Anyone exposed should seek appropriate medical advice.
Licenses and permits
Biohazard cleanup is commonly regulated, and the waste handling is subject to specific rules. Check with your state or local licensing agency and environmental authority for the company's required registrations and certifications before hiring.
Biohazard cleanup questions
Can a regular cleaner handle this?
Usually not. Biohazard work needs trained crews, protective equipment and regulated disposal. A general house cleaner should refer this job to a specialist.
Will my insurance cover biohazard cleanup?
It depends on your policy and the cause. Call your insurer before the work starts, ask what they require and keep all invoices and disposal records.
Is the area safe to enter after the cleanup?
Ask the company for a clearance inspection and a written report. Do not return to the area until the company confirms it is safe.
