Before You Call GZA GeoEnvironmental, Inc.

1. Do you take moisture readings every day and will you give me the drying log?
2. Are your technicians certified in water damage restoration?
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?

Ask for a Michigan residential builder or maintenance and alteration contractor license and look it up with the Department of Licensing and Regulatory Affairs. Also ask for proof of insurance and industry certification for the restoration crew.
