Before You Call Park Slope Best 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?
5. Do you also do remediation? If so, who checks your work?

For mold jobs over 10 square feet, New York State requires a licensed mold assessor and a separate licensed remediation contractor. Ask for both license numbers.
