Before You Call CNS Environmental

1. Where do you think the moisture is coming from, and who fixes it?
2. Will you set up containment and negative air, and how will you protect the rest of the home?
3. Is your company licensed for asbestos abatement here?
4. Who takes the samples, and which lab tests them?
5. Is your firm certified under the federal lead renovation rule?

For mold jobs over 10 square feet, ask for a New York State licensed mold remediator and a separately licensed mold assessor, plus the Nassau or Suffolk County home improvement license. Also ask for proof of insurance and industry certification for the restoration crew.
