Important note: Although the NYCCS annually verifies licenses and insurances of member companies, it is very possible that insurance coverage and licensure could lapse without the NYCCS being aware of it. It is always the property owners responsibility, before hiring any company, to perform any repair work, to obtain a certificate of insurance from the chimney company's insurance agent (listing both worker's compensation coverage and liability insurance coverage). Property Owners should always obtain a copy of the license numbers for the company and job foreman - ex. the company's NYC Home Improvement Contractors registration (HIC) and the job foreman's Certificate of Fitness (COF).
Please use the following links to help verify any contractor before hiring them.
