Before You Call Jeffries Basement 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?
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?

Ask for a New Jersey home improvement contractor registration and look it up with the Division of Consumer Affairs, or a Pennsylvania home improvement registration for work in Bucks County. Also ask for proof of insurance and industry certification for the restoration crew.
