The path requires years of training, state-mandated exams, and deep knowledge of local codes. If you’re serious about mastering this trade, you’ve come to the right place. We’ll walk you through every step, from apprentice to licensed master, with clarity and confidence.
What Does It Mean to Be a Master Plumber in Westchester County?
A master plumber is a licensed professional authorized to design, install, repair, and inspect plumbing systems—including gas lines—in compliance with New York State and local Westchester regulations. Unlike journeymen or apprentices, master plumbers can pull permits, run their own businesses, and supervise teams.
In Westchester County—a region with over 1 million residents and strict building codes—this credential carries significant weight. According to the U.S. Bureau of Labor Statistics (2025), plumbers in New York earn a median annual wage of $72,890, with master-level professionals often exceeding $90,000, especially in high-demand areas like White Plains, Yonkers, and Scarsdale.
Step-by-Step Guide: How to Become a Master Plumber in Westchester County, NY
Becoming a master plumber in New York isn’t just about skill—it’s about meeting legal requirements set by the New York State Department of State (NYSDOS). Here’s your roadmap:
1. Complete a High School Diploma or Equivalent
You’ll need at least a high school diploma or GED. Courses in math, physics, and shop class are helpful but not mandatory.
2. Enroll in a Plumbing Apprenticeship Program
New York requires 7 years of combined work experience and classroom training to qualify for the master plumber exam. Most candidates start with a registered apprenticeship:
- Duration: 4–5 years
- Hours: Minimum 6,000–8,000 hours of on-the-job training
- Classroom: At least 576 hours of technical instruction
Top programs in Westchester include:
- UA Local 210 Plumbers & Steamfitters (serving Westchester and NYC)
- Westchester Community College (offers vocational partnerships)
- ABC Empire Chapter (Associated Builders and Contractors)
💡 Pro Tip: While not required, attending a trade school like Lincoln Tech or UTI can accelerate your foundational knowledge before entering an apprenticeship.
3. Obtain a Journeyman Plumber License (Optional but Recommended)
Though New York State doesn’t issue a statewide journeyman license, many employers and municipalities (including parts of Westchester) recognize journey-level competency. Some towns may require it before you can work independently.
Check with your local building department (e.g., Town of Greenburgh, City of Mount Vernon) for specific rules.
4. Gain Required Experience
To sit for the Master Plumber exam, you must have:
- 7 years of full-time plumbing experience under a licensed master plumber
- At least 2 years of that time must be in New York State
Keep detailed logs of your work—dates, projects, supervisors, and types of systems installed (residential, commercial, gas, etc.). The NYSDOS may audit these records.
5. Pass the New York State Master Plumber Exam
Administered by the NYSDOS Division of Licensing Services, the exam covers:
- New York State Uniform Fire Prevention and Building Code
- Plumbing Code (based on the IPC – International Plumbing Code)
- Gas piping regulations
- Plan reading and system design
Exam Details:
- Format: 100 multiple-choice questions
- Duration: 4 hours
- Passing score: 70%
- Fee: $100 (as of 2026)
Study resources:
- PSI Exams (official test provider): psiexams.com
- NASCLA Contractor Guide (includes plumbing sections)
- Practice tests from PlumbingExamPrep.com
⚠️ Note: You must also pass a business/law exam if you plan to operate your own plumbing company.
6. Apply for Your Master Plumber License
After passing the exam, submit your application to NYSDOS with:
- Proof of experience (notarized affidavits from employers)
- Exam results
- Application fee ($100–$150)
- Background check (if requested)
Processing takes 4–8 weeks. Once approved, you’ll receive your license number—valid for 3 years.
7. Register with Westchester County Municipalities
Your NYS license allows you to work statewide, but most Westchester towns require local registration. For example:
- City of Yonkers: Requires a $75 annual business registration
- Town of Harrison: Needs proof of insurance and license copy
- Village of Scarsdale: Mandates a local permit for all plumbing work
Always verify with your town’s Building Inspection Department before starting work.
