Before You Call TTI Environmental Inc.

2. Will you set up containment and negative air, and how will you protect the rest of the home?
3. Do you also do remediation? If so, who checks your work?
4. How many air samples will you take, and will you take an outdoor control sample?

In Pennsylvania ask for the contractor’s state home improvement registration number, and in Philadelphia also ask for the city contractor license. Also ask for proof of insurance and industry certification for the technicians.
