Before You Call National Building Services & Maintenance 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. Will you remove the carpet and pad that the sewage touched?
4. How high up the walls will you cut, and why?

Ask for a Louisiana mold remediation license and look it up with the Louisiana State Licensing Board for Contractors. Also ask for proof of insurance and industry certification for the restoration crew.
