Before You Call FACS: Industrial Hygienists & Environmental Consultants

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 firm certified under the federal lead renovation rule?

Ask for a California contractor license number and look it up with the Contractors State License Board. Also ask for proof of insurance and industry certification for the restoration crew.
