Before You Call Leakmasters 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?
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 the company’s California contractor license number and look it up with the Contractors State License Board. Also ask for proof of insurance and industry certification for the technicians doing the drying or mold work.
