Certified Asbestos Investigators, Contractors and Firms

Certified Asbestos Investigators

Please click the following link to get the list of CAIs. The NYC DEP certifies more than 250 asbestos investigators per year. Certificates are valid for two years. Please note that business telephone numbers are listed alongside the names of certificate holders who have requested that their number be displayed on the Department’s website.

DEP does not provide recommendations or referrals. While selecting an asbestos investigator, the Asbestos Control Program (ACP) suggests reviewing the individual’s violation history (if one exists). Violation histories may be obtained within 48-72 hours by faxing a request to (718) 595-3749.
