Before You Call Bio-One of Delaware

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. Will you remove the carpet and pad that the sewage touched?
4. How high up the walls will you cut, and why?
5. Are your technicians trained in bloodborne pathogen safety?

Ask for the contractor’s Delaware business license and any state trade license, and check permits with your city or county. Also ask for proof of insurance and industry certification for the restoration crew.
