Before You Call Engineering Remediation (ERRG)

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. Are your technicians trained in bloodborne pathogen safety?
4. How do you dispose of the waste, and will you give me a disposal record?

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.
