Thinking about a career in plumbing—or already on the path to becoming a master plumber? You’re not alone. Many skilled tradespeople wonder, “How much does a master plumber make an hour?” The answer isn’t just a number—it depends on location, experience, certifications, and even the type of projects you take on. In this guide, we’ll break down real-world earnings, regional differences, and how you can maximize your income as a licensed plumbing professional.
What Is a Master Plumber?
Before diving into earnings, it’s important to understand what sets a master plumber apart. Unlike apprentices or journeymen, a master plumber has:
- Completed 4–5 years of hands-on training (often through an apprenticeship)
- Passed rigorous state or local licensing exams
- Demonstrated expertise in complex installations, code compliance, and system design
- Authority to pull permits, supervise teams, and run their own plumbing business
This advanced skill level directly impacts earning potential—making the master plumber one of the highest-paid roles in the trade.
