Biohazard cleanup generally is not licensed as its own trade in Colorado the way electricians or plumbers are, so the burden of checking falls on the person hiring. That can feel like a lot to ask of someone who is grieving or in shock. It helps to have a relative or friend make the calls with this list in hand, and to ask every provider the same questions so answers can be compared side by side.
Nothing below requires technical knowledge to evaluate. You are listening for specific answers, a willingness to put things in writing, and respect for your situation.
The core questions
- What training have the workers who will be in my home completed, such as OSHA bloodborne pathogens training, and can I see proof?
- Which respirators and protective equipment will be worn for this job?
- How will you determine how far contamination has spread under flooring and behind walls?
- Which materials do you expect to remove, and which will be cleaned in place?
- Who transports regulated medical waste from this job, and will I receive disposal paperwork?
- Do you carry general liability and workers' compensation insurance, and can you send certificates?
- Will you give me a written scope and estimate before work begins?
- Will you work directly with my insurer, and what will I owe if the insurer pays less than the invoice?
- How will personal items, documents and valuables be handled?
- How will you confirm the work is complete, and what happens if odor returns?
