Dreaming of running your own plumbing business or taking on high-stakes commercial projects in the Lone Star State? You’ll need more than just wrenches and pipes—you need official recognition. How to get licensed as a master plumber in Texas is a common but critical question for skilled tradespeople aiming to advance their careers. This guide breaks down every requirement, timeline, and insider tip you need to earn that prestigious license—legally and efficiently.
What Is a Master Plumber License in Texas?
In Texas, plumbing licenses are regulated by the Texas State Board of Plumbing Examiners (TSBPE). A Master Plumber license is the highest level of plumbing certification available in the state. It allows you to:
Pull permits for any plumbing project (residential or commercial)
Supervise journeymen and apprentice plumbers
Start and operate your own plumbing business
Design complex plumbing systems
Unlike some states, Texas does not offer reciprocity with other states’ licenses, so even if you’re licensed elsewhere, you must meet Texas-specific requirements.
💡 Fun fact: As of 2024, Texas has over 28,000 licensed plumbers—but fewer than 9,000 hold a Master Plumber license, according to TSBPE data.
Who Can Apply for a Master Plumber License in Texas?
You can’t skip straight to master status. Texas requires progressive experience:
Apprentice: Entry-level, works under supervision.
Journeyman Plumber: Must hold this license for at least 4 years before applying for master status.
Master Plumber: The final step.
To qualify for the Master Plumber exam, you must have:
48 months (4 years) of practical plumbing experience as a licensed Journeyman in Texas (or equivalent out-of-state experience accepted with documentation)
Proof of liability insurance (once licensed)
No disqualifying criminal history
⚠️ Note: Experience gained before obtaining your Journeyman license does not count toward the 4-year requirement for Master status.
