Before You Call OSI Inspection Services

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?

Ask for a Florida contractor license and, for mold work, a Florida mold remediator license, and look both up with the Department of Business and Professional Regulation. Also ask for proof of insurance and industry certification for the restoration crew.
