Before You Call O2 Clean Breathing 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. Where do you think the moisture is coming from, and who fixes it?
4. Will you set up containment and negative air, and how will you protect the rest of the home?
5. Do you also do remediation? If so, who checks your work?

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.
