Thinking about a career in plumbing? Youโre not alone. With strong job demand, solid pay, and hands-on work that makes a real difference, plumbing is a smart trade to pursue. But one of the first questions on every aspiring plumberโs mind is: how long does it take to be a certified plumber? The answer isnโt one-size-fits-allโit depends on your state, training path, and dedication. In this guide, weโll walk you through every step, timeline, and requirement so you can plan your journey with confidence.
What Does โCertified Plumberโ Actually Mean?
Before diving into timelines, itโs important to clarify terminology. In the U.S., the term โcertified plumberโ isnโt universal. Most states use licensing, not certification, to regulate who can legally perform plumbing work. While โcertificationโ may refer to voluntary credentials (like from the International Code Council), licensure is mandatory to work independently.
According to the U.S. Bureau of Labor Statistics (BLS), all states and localities require plumbers to be licensed if they work on residential or commercial systems beyond basic repairs. So when people ask, โHow long does it take to be a certified plumber?โ they usually mean: How long until I can get my plumbing license and work legally on my own?
Step-by-Step Timeline: From Beginner to Licensed Plumber
Becoming a licensed plumber typically follows a structured path that blends classroom learning and on-the-job experience. Hereโs the standard U.S. route:
1. High School Diploma or GED (0โ1 Year)
Most plumbing programs and unions require a high school diploma or equivalent. If you already have one, you can skip this step. If not, earning a GED takes 2โ6 months with consistent study.
2. Enroll in a Plumbing Program or Apprenticeship (0โ2 Years)
You have two main entry paths:
- Trade School/Technical College:
Programs last 6 months to 2 years and cover plumbing theory, blueprint reading, safety codes, and basic hands-on skills. Tuition ranges from $1,000 to $15,000.
Pros: Faster start, structured curriculum.
Cons: Less real-world experience; youโll still need an apprenticeship for licensure in most states. - Union or Non-Union Apprenticeship:
Sponsored by organizations like UA (United Association) or local contractors, these combine paid on-the-job training with classroom instruction.
Duration: 4โ5 years (standard across most states).
Pay: Starts at ~50% of a journeymanโs wage and increases yearly.
๐ก Expert Insight:
โApprenticeships are the gold standard,โ says Mike Smith, a master plumber with 22 years of experience in Texas. โYou earn while you learn, and employers value that hands-on time.โ
3. Complete Required Work Hours (4โ5 Years)
To qualify for a journeyman license, most states require 4,000โ8,000 hours of supervised plumbing workโtypically achieved through a 4- to 5-year apprenticeship.
For example:
- California: 8,000 hours + 720 classroom hours
- New York: 7,000 hours + 500 classroom hours
- Texas: 4,000 hours under a master plumber
You can verify your stateโs exact requirements via the U.S. Department of Laborโs apprenticeship database or your stateโs licensing board.
4. Pass the Journeyman Plumbing Exam
Once youโve logged enough hours, you can sit for your journeyman plumber exam. This test covers:
- Local and national plumbing codes (IPC or UPC)
- Math calculations (pipe sizing, pressure, flow rates)
- Safety protocols
- System design
Pass rates vary, but thorough prep using study guides or prep courses boosts success. The exam usually takes 3โ4 hours and costs $50โ$200.
5. Work as a Journeyman (Optional: 1โ5+ Years)
After passing, youโre a licensed journeyman plumberโqualified to install, repair, and inspect plumbing systems under general supervision. Many plumbers work at this level for years.
But if you want full independence (e.g., start your own business), youโll need a master plumber license, which requires:
- Additional 1โ5 years of experience (varies by state)
- Passing a more advanced exam
State-by-State Variation: Why Location Matters
There is no national plumbing license in the U.S. Each state sets its own rules. For instance:
Florida | 4 years | 6,000 | Yes |
Illinois | 4โ5 years | 8,000 | Yes |
Oregon | 4 years | 6,400 | Yes |
Pennsylvania | Varies by city | 4,000โ8,000 | Yes (local) |
๐ Pro Tip: Always check your stateโs plumbing licensing board before starting. Some cities (like Chicago or New York City) have additional local requirements.

Can You Speed Up the Process?
While most paths take 4โ5 years, there are limited ways to accelerate:
- Military Training: Veterans with plumbing experience in the armed forces may qualify for credit toward apprenticeship hours.
- Prior Experience: If youโve worked as a helper or in a related trade (e.g., HVAC), some states allow partial hour credit.
- Accelerated Programs: A few technical schools partner with unions to offer โfast-trackโ apprenticeships, but these still require the same total hoursโjust with more intensive scheduling.
However, beware of โget licensed in 6 monthsโ scams. Legitimate plumbing licensure requires verified hands-on experience. Skipping steps risks failing your examโor worse, violating state law.
