Before You Call Wellington 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. Do you also do remediation? If so, who checks your work?
4. How many air samples will you take, and will you take an outdoor control sample?
5. Is your company licensed for asbestos abatement here?

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.
