Before You Call 307 Environmental

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. Is your company licensed for asbestos abatement here?

Wyoming has no statewide general contractor license, so check with the City of Sheridan or Sheridan County, and use a state licensed electrician for electrical work. Also ask for proof of insurance and industry certification for the restoration crew.

They list no storefront. Ask where the business is based and whether the crew is their own.
