Before You Call Narwhal Plumbing

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 the contractor license your city or village requires, since Illinois has no statewide general contractor license, and check it with the local building department. Also ask for proof of insurance and industry certification for the technicians.
