Frequently asked questions
How much does biohazard cleanup cost?
Published ranges are $1,500 to $7,500 for most residential situations, with complex cases exceeding $20,000. By scenario: minor blood cleanup $500 to $2,500, unattended death discovered early $1,500 to $5,000, suicide cleanup $1,500 to $5,500, homicide or violent crime $2,500 to $9,000, severe decomposition $4,000 to $20,000 or more, and multi-room or large-scale work $7,500 to $25,000 or more.
Why does the price change so much with time?
Because fluids travel. An unattended death discovered early is published at $1,500 to $5,000; severe decomposition is $4,000 to $20,000 or more. That is the same event at different points in time. Early, contamination sits on surfaces. Later it has reached flooring, subfloor and wall cavities, and the job becomes removal and reconstruction rather than cleaning.
Who is legally allowed to do this work?
It depends on the state. California requires anyone paid to clean a trauma scene to register with the Department of Public Health under the Medical Waste Management Act, and publishes the register: 364 practitioners were listed as of 12 May 2026. Many states have no register at all, in which case certification, waste-disposal permits and insurance are the checkable signals instead.

Does being on the California register mean a company is good?
No, and the state says so explicitly. The published list states that registration carries no expressed or implied endorsement of the quality of work or service provided. It also notes that registration is separate from Contractors' State License Board licensing, and that the Department does not require a practitioner to hold a contractor's licence, though some restoration jobs may require one. Registration is a floor, not a recommendation.

Is biohazard cleanup covered by insurance?
Often yes. Homeowners, renters and commercial property policies commonly cover it, typically including labour, disposal fees, decontamination and removal of structural material, though what any given policy pays depends on that policy. Notify the insurer before work starts, photograph everything first, and ask whether the company will bill the insurer directly.
Is reconstruction included in the quote?
Usually not. Remediation removes contaminated material; putting the room back is normally a separate contractor and a separate quote, and may require a licensed contractor where the remediation itself does not. On a late-discovery job the reconstruction can be the larger number, so ask explicitly which of the two you are being quoted.
What is category 3 water and why does sewage get treated differently?
Water is classified by contamination rather than volume, and sewage falls in the most contaminated category. That changes the response: porous materials that absorbed it are generally removed rather than dried, the area is contained so contaminated air is not spread, protective equipment and decontamination procedures apply, and the waste leaving the property may be regulated. Drying a sewage-affected floor without removing porous materials is the most common expensive mistake.
What should I ask a company before hiring them?
Five things: are you registered or certified for this work and can you evidence it now; is the quote remediation only or does it include reconstruction; who removes the regulated waste and under what permit; will you bill my insurer directly and have you done so with this insurer before; and when can you start and who is actually on site. The waste and reconstruction questions are the two a general cleaning company cannot answer well.
