Before You Call FACS: Industrial Hygienists & Environmental Consultants

1. Do you also do remediation? If so, who checks your work?
2. How many air samples will you take, and will you take an outdoor control sample?
3. Is your company licensed for asbestos abatement here?
4. Who takes the samples, and which lab tests them?

Ask for the contractor license your city or village requires, since Illinois has no statewide general contractor license, and check it with the local building department. Also ask for proof of insurance and industry certification for the technicians.
