Before You Call Capstone Waterproofing Solutions

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 the license that fits where you live, a DC home improvement license, a Maryland Home Improvement Commission license or a Virginia Board for Contractors license, and look it up with that agency. Also ask for proof of insurance and industry certification for the technicians.
