How we work
Our Mission
Why New York Plumbing Directory exists, what we are, and what we are explicitly not.
Trust Standards
Editorial neutrality, listing acceptance, dispute handling, and removal policies in plain language.
How We Verify
The exact documents, registries, and re-checks behind the verified badge.
Data Sources
Every public registry that feeds the directory: NYC DOB Licensed Master Plumbers, county & city licensing boards, PHCC of New York, and the New York Department of State Division of Corporations.
Disclaimer
Licensing, liability, and lead-referral disclaimers. The canonical version that every page references.
Contact / Report a listing
Questions, corrections, removal requests, and press inquiries.
Authoritative outside reading
We always recommend that homeowners read at least one government or industry-standard source before hiring a plumber. These are the references we link to most often.
NYC Department of Buildings -- Licensed Master Plumber
The NYC agency that issues the Licensed Master Plumber (LMP) credential and regulates plumbing work across the five boroughs. Public licensee lookup and DOB rules.
New York Plumbing Code
The plumbing provisions of the NYS Uniform Code (and the NYC Plumbing Code) that licensed plumbers must follow -- approved materials, venting, backflow protection, and inspection requirements.
County & city licensing (e.g. Nassau, Suffolk)
Outside NYC, counties and cities -- Nassau, Suffolk, Westchester, Buffalo, Rochester, Syracuse, Albany -- license plumbers locally and enforce permits within their jurisdiction. Licensed-contractor lookups.
EPA WaterSense (epa.gov/watersense)
Federal guidance on water-efficient fixtures and finding WaterSense-labeled products that cut water use without sacrificing performance.
