Why You Need a Licensed Plumber in NYC

New York City law requires that all plumbing work be performed by or under the supervision of a NYC Licensed Master Plumber. This is not just a formality — it is your protection. A licensed plumber has passed rigorous examinations, demonstrated years of experience, and maintains ongoing education requirements. More importantly, only a licensed plumber can legally pull NYC DEP permits for sewer and water main work. Hiring an unlicensed contractor puts you at risk of code violations, failed inspections, voided insurance claims, and potentially dangerous work.

How to Verify a NYC Plumber License

You can verify any plumber's license through the NYC Department of Buildings (DOB) website at nyc.gov/buildings. Search by the contractor's name or license number to confirm their license is active and in good standing. You should also ask to see their insurance certificates — a legitimate contractor will provide these without hesitation. Sewer & Water Pros is happy to provide our license number, insurance certificates, and DEP certification upon request.
