Before You Call Gold Seal Waterproofing

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?

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.
