Dreaming of becoming a licensed plumber? You’re not alone—plumbing is one of the most in-demand and well-paying trades out there. But how long does it actually take to become a licensed plumber? The truth is, there’s no universal answer. The path depends on where you live, your education level, and how quickly you move through your apprenticeship and licensing exams.
Typically, it takes about 4 to 5 years to become a licensed plumber. That includes completing an apprenticeship, passing exams, and fulfilling state-specific requirements. Some fast-track programs promise quicker routes, but they usually still involve practical hours and formal certification.
In this article, we’ll break down each step of the journey so you can understand what to expect—and how long each stage might take. Whether you’re fresh out of high school or switching careers, we’ll give you the inside scoop on how long it really takes to get licensed and start earning as a professional plumber.

Why Plumbing Licenses Matter
You can’t just wake up one day, grab a wrench, and start working as a plumber. Plumbing work impacts public health and safety, so states require licenses to ensure plumbers are trained, skilled, and up to code.
Licensing proves:
- You’ve had formal training
- You understand plumbing codes
- You can safely install, repair, and maintain systems
Without a license, you may be limited to assisting roles or working under supervision. Worse, you could face fines for doing unlicensed work. If you’re planning to start your own plumbing business, a license is mandatory.

General Overview of the Licensing Journey
The journey to a plumbing license usually looks like this:
- High school diploma or GED
- Apprenticeship program (typically 4-5 years)
- Journeyman license exam
- Optional master plumber certification
- Continuing education and renewals
Some states allow you to work as an apprentice almost immediately, while others require classroom instruction first. Either way, your clock starts the day you commit to training.
Prerequisites Before Applying for a License
Minimum Education Requirements
To begin the licensing process, most states require a high school diploma or GED. Why? Because plumbing involves math, science, and problem-solving. You’ll need to read blueprints, calculate pipe lengths, and understand water pressure and flow rates.
Some technical schools even offer pre-apprenticeship plumbing programs that include certifications in:
- Basic safety
- Plumbing math
- Blueprint reading
- Tool identification
If you’re still in high school, you can get a head start by taking courses in algebra, physics, and vocational training.
High School Courses That Help
Want a head start? Focus on these subjects:
- Algebra & Geometry: Helps with measuring pipe lengths and calculating slopes.
- Chemistry: Useful for understanding water properties and chemical treatments.
- Technical Drawing: Prepares you to read blueprints and schematics.
- Shop Class or Woodworking: Develops your hands-on mechanical skills.
Many vocational schools offer introductory courses in plumbing, giving you a leg up when applying for apprenticeships.

Plumbing Apprenticeship
What Is a Plumbing Apprenticeship?
An apprenticeship is where the magic happens. It’s a hands-on training program where you work under licensed plumbers, earn a wage, and learn the trade from the ground up. Think of it as a paid internship—but way more intense and way more valuable.
Apprenticeships combine:
- On-the-job training (8,000+ hours)
- Classroom instruction (500+ hours)
- Real-world problem-solving
You’ll learn how to:
- Install pipes, fixtures, and appliances
- Read blueprints and building codes
- Use specialized tools and safety equipment
Most apprenticeships are run by trade unions, plumbing associations, or technical schools. Some are even sponsored by employers, meaning you get paid while learning.
How Long Does an Apprenticeship Last?
Typically, a plumbing apprenticeship takes 4 to 5 years to complete. This isn’t just about putting in time—it’s about building the skills and experience needed to handle real-world plumbing issues confidently.
Here’s what your time might look like:
- Year 1: Learning the basics—tools, safety, pipe systems
- Year 2–3: Hands-on work in residential and commercial settings
- Year 4: More complex tasks—gas lines, advanced diagnostics
- Year 5: Prepping for the journeyman license exam
Some states may allow you to test earlier, but you’ll still need to meet minimum hours. Don’t expect to shortcut this step. Plumbing is a craft—and mastery takes time.

Becoming a Journeyman Plumber
Requirements to Become a Journeyman
Once you finish your apprenticeship, you’re eligible to take the journeyman plumbing exam—a major milestone on the road to licensure.
Requirements generally include:
- Proof of apprenticeship completion (4–5 years)
- Classroom instruction hours
- Background check or fingerprinting (in some states)
- Exam application and fee
The exam typically covers:
- Plumbing codes and laws
- Water distribution systems
- Sanitary drainage systems
- Safety protocols and materials
Passing the exam officially makes you a licensed journeyman plumber, allowing you to work independently under a master plumber or contractor.
Duration and Process of Journeyman Licensing
How long does it take to become a journeyman? Including your apprenticeship, the full process takes about 4 to 6 years. This depends on your pace and your state’s requirements.
The exam itself may take a few hours, and results are often available within a week or two. Once you pass, your license will typically be valid for 1 to 3 years and will need to be renewed periodically.
You can work as a journeyman indefinitely, or you can choose to level up and become a master plumber, which opens even more doors—like starting your own business or supervising apprentices.
Advancing to Master Plumber
What Is a Master Plumber?
Becoming a master plumber is like earning your black belt in plumbing. It’s the highest licensure level you can reach in the trade—and it comes with more responsibility, more authority, and yes, more earning potential.
A master plumber can:
- Pull permits
- Supervise journeymen and apprentices
- Start and run a plumbing business
- Take on complex commercial or industrial projects
The title isn’t just for show. It signifies that you’ve put in the work, have deep expertise, and can manage full-scale plumbing operations from planning to execution.
How Long Does It Take to Reach Master Level?
After you’ve been working as a journeyman for 1 to 5 years (depending on your state), you become eligible to apply for master plumber status.
The timeline looks like this:
- 4–5 years as an apprentice
- 1–5 years as a journeyman
- Total: 5–10 years to become a master plumber
You’ll also need to pass a master plumber exam, which is more challenging than the journeyman test. It often includes:
- Advanced plumbing codes and calculations
- Business law and contracting knowledge
- Project management skills
- Blueprint interpretation
While it takes time, the payoff is big: master plumbers earn more and have the ability to work independently or launch their own company.

Licensing Requirements by State
State-by-State Variations in Timelines
Here’s the kicker—not all states have the same licensing timeline. Some states have no statewide plumbing license requirement, leaving it up to cities or counties. Others have a uniform state process that covers everything from apprentice to master plumber.
Here are a few examples:
- Texas: Requires 4,000 hours as an apprentice to take the journeyman exam; then 8,000 hours as a journeyman to become a master.
- California: No statewide license, but cities like Los Angeles require registration and exams.
- New York: Requires licensing in most major cities but not always at the state level.
- Florida: Requires a combination of education and 4+ years of experience before licensing exams.
Before you begin, check your state and local requirements on government or contractor licensing websites. Otherwise, you might waste time or be ineligible for exams.
Where It’s Faster or Slower to Get Licensed
If you’re looking for speed, some areas let you complete the process quicker through non-union apprenticeships, trade schools with built-in experience, or more lenient local regulations. States like Nevada or Alaska may have shorter timeframes due to labor demand.
In contrast, areas with stricter building codes—like Massachusetts, Illinois, or California (in specific cities)—may require more formal education, longer apprenticeships, or higher exam standards, which can stretch your timeline to the upper end of 6–10 years.
Exam Requirements
Types of Exams and Passing Criteria
Licensing exams are more than just written tests—they often include both practical and theoretical components. You may be tested on:
- Pipe sizing and layout
- Venting and drainage systems
- Safety codes (OSHA standards)
- Gas piping installations
- Math and physics related to pressure, volume, and flow
Typical formats include:
- Multiple-choice questions
- Blueprint interpretation tasks
- Scenario-based problem-solving
To pass, you generally need a score of 70% or higher. Exams are often timed (2–4 hours) and administered by state-approved boards or national testing agencies like PSI or NCCER.
How to Prepare and Time Needed for Study
Preparation is key. Most plumbers spend 2–3 months studying for the journeyman exam, while master exam prep could take longer due to the business and legal content.
Best prep methods:
- Official state exam prep guides
- Online practice tests
- Trade school review classes
- Apprenticeship review courses
Set aside 30–60 minutes a day for review, especially in the weeks leading up to the test. Cramming won’t cut it—this test requires genuine understanding of complex systems and codes.

Costs Involved in Getting Licensed
Tuition, Exam Fees, and Licensing Costs
Becoming a plumber isn’t free. You’ll need to budget for:
- Apprenticeship programs: Free or paid depending on union/non-union
- Trade school tuition: $1,000–$10,000 (for certificate programs)
- Exam fees: $100–$300 per exam
- Licensing application: $50–$200
- Renewal fees: Every 1–3 years, typically $50–$100
Plus, you’ll need to invest in:
- Tools and protective gear ($500–$1,000)
- Textbooks and study guides
- Travel and time off work for classes or testing
Over time, though, this investment pays off. Plumbers can earn anywhere from $50,000 to over $100,000 a year depending on their license and location.
Financial Aid or Paid Apprenticeships
Worried about the cost? Don’t be. Many union apprenticeships are tuition-free and pay a wage while you learn. You may also qualify for:
- Workforce development grants
- Employer-sponsored programs
- Scholarships from trade organizations
These options can significantly reduce or even eliminate your out-of-pocket expenses. The key is to research programs in your area and apply early—these slots are often limited and competitive.
Fast-Track Programs
Are Accelerated Programs Available?
Yes, fast-track plumbing programs exist—but let’s be clear: there’s no legitimate shortcut that skips the core training required for licensing. That said, some technical schools and training centers offer accelerated classroom programs that pack the theory portion into 6 to 12 months instead of 2 years.
What these programs do is:
- Condense the bookwork
- Combine classroom learning with simulated hands-on practice
- Help fast-track your entry into an apprenticeship or journeyman program
Some trade schools even work directly with unions or employers to place students immediately after graduation.
Keep in mind, though:
- Accelerated programs still require you to complete an apprenticeship
- You must still meet the required hours of experience before taking your license exam
- State boards do not waive the hands-on training just because you finish classroom instruction quickly
So while you can fast-track your education, there’s no skipping the years of hands-on work. It’s a trade-off between quick theory prep and long-term, required fieldwork.
Pros and Cons of Speeding Up the Process
Pros:
- Get into the workforce faster
- Ideal for motivated, disciplined learners
- Some programs include job placement
Cons:
- Intense workload and fast pace
- May sacrifice depth of understanding
- Doesn’t reduce required apprenticeship hours
Fast-track programs are best for self-starters or people switching careers who want to hit the ground running. Just make sure the program is recognized by your state licensing board before enrolling.
Continuing Education for Plumbers
Is Ongoing Training Required?
Absolutely. Even after you’re licensed, most states require plumbers to complete continuing education (CE) courses to keep their licenses active. CE helps you stay up to date on:
- New plumbing codes
- Safety regulations
- Green building practices
- New materials and technologies
How often you need CE varies by state:
- Annually in states like Texas and Florida
- Every 2-3 years in places like Illinois or Michigan
Some states even require CE before each renewal. Check with your local licensing authority to know exactly what your obligations are.

Common Challenges and How to Overcome Them
Balancing Work, Study, and Life
Let’s be real—becoming a plumber takes grit. Apprenticeships are full-time jobs. Throw in night classes, study time, and family responsibilities, and you’ve got a tight schedule.
Tips to manage the juggle:
- Use a calendar: Schedule study blocks around work
- Communicate with employers: Most know apprentices have school obligations
- Take care of your body: Plumbing is physically demanding—sleep and nutrition matter
- Find a mentor: Someone who’s been through it can offer advice and motivation
Plumbing isn’t a desk job. It’s mental, physical, and sometimes dirty—but that’s what makes it rewarding.
Success Stories and Real-Life Timelines
How Long It Took Real Plumbers
