What should I check before buying a biohazard cleaning business?

Biohazard cleaning covers jobs that most people never want to see: unattended deaths, trauma, hoarding, contamination. The work is irregular, urgent and emotionally heavy. A buyer is acquiring a trusted name with a small group of referrers and a team willing to answer the phone at any hour. Diligence should test those things first, and the trucks second.

Where the calls come from

Ask for a breakdown of recent jobs by source: insurers, property managers, landlords, funeral homes, police-adjacent contacts, families. Referrers choose a firm because they trust one person to arrive and behave well. Meet the biggest ones with the owner’s consent, and ask what would make them keep or drop the firm after a change of ownership.

On-call coverage and the crew

Find out who answers the phone at night, who attends first and how the rota is shared. If the owner covers most of it, you inherit that load. Ask how crews are trained, supported and debriefed, and how long they have stayed. Losing two experienced technicians can stop a small firm. Discuss retention before closing, not afterwards.

Payers, insurance and equipment

Ask how long insurers and property managers usually take to pay, and look at aged receivables. Review the firm’s own insurance and any claims history, and how contaminated waste is handled and documented. Inspect vehicles, protective gear and specialist equipment, and ask which items are owned, leased or financed.

Questions to put to the owner

• What happens when two serious calls arrive together?
• Has any job led to a complaint or an insurance claim?
• Which referrers have been lost, and why?
• Will you stay on during the handover?
