Before You Call O'Reilly Talbot & Okun Associates

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 a Massachusetts home improvement contractor registration and, for structural work, a construction supervisor license, and look both up with the state. Also ask for proof of insurance and industry certification for the restoration crew.
