How do I check a biohazard cleanup company before I hire them?

Verify four things: state registration where your state requires it, IICRC certification of the technicians who will actually attend, a documented medical waste disposal chain, and experience billing insurance. Then get an itemised written scope before any work starts. A company that resists any of these has told you something.

The short version

Verify state registration if your state requires it. In California it also decides whether your claim is reimbursable.
Ask about the technicians attending, not about the company’s history.
Ask where the waste goes and who transports it. A vague answer is the answer.
Get an itemised written scope before work begins.
Nobody can require you to use them. Not an insurer, not the police, not the company already parked outside.

Why this page exists

In most transactions you can judge the work. Here you cannot. You will not be present, you would not know what correct looks like if you were, and by the time anything is visibly wrong the evidence has been removed and disposed of.

You are also, usually, being asked to make this decision on the worst day of your life. That combination — no ability to evaluate, no capacity to negotiate, high price, urgent framing — is the precise set of conditions that produces overcharging. None of that means the industry is dishonest. It means the ordinary protections a buyer relies on are absent, and you have to substitute deliberate questions for them.

The four things to verify

1. State registration, where your state requires it. Most states do not license this work as its own trade, but two we have confirmed do regulate it directly. California requires registration with the Department of Public Health as a Trauma Scene Waste Practitioner before work begins. Florida requires biomedical waste transporter registration above a weight threshold. What your state requires.

In California this is not paperwork trivia: the state compensation program will only reimburse cleanup done by a registered practitioner. Hire outside that list and you may lose the claim.

2. Certification of the people actually attending. Ask whether the technicians who will be in your home hold the IICRC’s Trauma and Crime Scene Technician certification — not whether the company “is IICRC certified”, which is a category error, because the IICRC certifies people. What each credential means.

If a company says it is “OSHA certified”, it is describing something that does not exist. OSHA sets requirements for employers; it does not certify companies. Ask instead to see their written exposure control plan and their most recent bloodborne pathogens training records. Those are real documents that a compliant company has.

3. The disposal chain. Ask who transports the waste, where it is treated, and whether they can show the documentation. Regulated medical waste travels under federal rules as UN 3291, and responsibility for it runs from collection all the way to final treatment. A company that cannot describe its chain in specifics either does not have one or is not thinking about it. How the waste chain works.

4. Insurance billing experience. Ask whether they bill carriers directly, and whether they issue a Certificate of Treatment. Claims routinely require it. A company that has never done this before will cost you time you do not have.

What a fair quote looks like

Itemised, with labour, materials, disposal, equipment and any reconstruction shown separately.
In writing, before work begins.
Explicit about what is not included — particularly the line between remediation and putting the room back.
Explicit about the disposal fee, which is a real cost and should be visible rather than folded in.
Written before anyone starts, not presented afterwards.

An hourly rate on its own tells you almost nothing. Published hourly figures for this work range from $25 to $600 depending on who is publishing and what they are counting, which makes an unqualified hourly number close to meaningless. More on cost.

Red flags

Tells you an insurer requires you to use them, or that your claim depends on it. That is not true.
Wants a signature before giving you a written itemised scope.
Cannot name where the waste is treated, or who transports it.
Says the company is “OSHA certified” and cannot produce an exposure control plan or training records.
Presses you to decide today, or describes the property as deteriorating by the hour to close the sale.
Arrived at the scene uninvited and will not say who told them.
Quotes a single number with no breakdown, or refuses to separate remediation from reconstruction.
Cannot produce state registration in a state that requires it.
Will not commit to issuing a Certificate of Treatment.
Asks you to sign a direction-to-pay or assignment of benefits you have not read.

This checklist prints on one page.

The one that matters most

An assignment of benefits or direction to pay hands the company your right to deal with your own insurer. There are legitimate reasons to sign one and it is often routine. But signing it on a doorstep, unread, on the day of a death, is how families end up with a dispute they did not know they had entered.

You are allowed to say: I will read this and call you back in an hour. Any company worth hiring will say yes.

What to do next

Check your state’s requirements before you call anyone. Start here.
Call two companies, not one.
Ask the four questions above and note who answers them specifically.
Get the itemised scope in writing.
Open your insurance claim and, if a crime occurred, your state compensation claim.
