Before You Call BIO-ONE of ST. LOUIS

1. Where do you think the moisture is coming from, and who fixes it?
2. Will you set up containment and negative air, and how will you protect the rest of the home?
3. Are your technicians trained in bloodborne pathogen safety?
4. How do you dispose of the waste, and will you give me a disposal record?
5. Do you sort items with the family, or do you haul everything away?

Missouri has no statewide general contractor license, so check with your city or county, and in Illinois ask a roofer for a state roofing license. Also ask for proof of insurance and industry certification for the restoration crew.
