Thinking about a career in plumbing but unsure how long it takes to get certified? You’re not alone. Many aspiring tradespeople want clear, realistic timelines before committing time and money. How long does it take to get certified in plumbing depends on your location, training path, and dedication—but most people complete the process in 2–5 years. In this guide, we’ll break down every step, timeline, and tip so you can plan your journey with confidence.
What Does “Plumbing Certification” Actually Mean?
Before diving into timelines, it’s important to clarify terminology. In the U.S., “certification” often refers to licensure, which is legally required to work as a plumber in most states. While some organizations offer voluntary certifications (like from the National Inspection Testing and Certification Corporation), the core requirement is a state-issued plumbing license.
Licensing typically follows a three-tier system:
- Apprentice (entry-level, works under supervision)
- Journeyman (can work independently)
- Master Plumber (can run a business, supervise others)
Each level requires specific hours of experience and passing an exam.
How Long Does It Take to Become a Licensed Plumber?
The short answer: 2 to 5 years—but let’s unpack that.
1. Apprenticeship Path (Most Common)
The traditional route involves a paid apprenticeship, which usually lasts 4 to 5 years. During this time, you’ll:
- Work 2,000 hours per year on real job sites (totaling ~8,000 hours)
- Complete 144–200 hours per year of classroom instruction
- Learn pipefitting, blueprint reading, local codes, and safety protocols
According to the U.S. Bureau of Labor Statistics (BLS), most plumbers learn through registered apprenticeships sponsored by unions (like UA Plumbers & Pipefitters) or contractor associations.
💡 Pro Tip: Some states (like California or Texas) allow accelerated paths if you have prior military or trade experience.
2. Trade School + Apprenticeship Combo
Want to shorten the timeline? Enroll in a plumbing trade school first. Programs typically last 6 months to 2 years and may count toward your apprenticeship hours.
For example:
- Pennsylvania College of Technology: Offers a 2-year associate degree in plumbing.
- Tulsa Welding School: Provides a 7-month plumbing diploma.
After graduation, you still need to complete an apprenticeship—but you may qualify for advanced placement, reducing total time to 2–3 years.
3. Direct Licensing (Rare)
A few states (e.g., Kansas, Wyoming) allow you to sit for the journeyman exam with proof of experience—no formal apprenticeship required. However, you’ll still need 4+ years of documented work under a licensed plumber.
State-by-State Timeline Comparison
Licensing rules vary significantly by state. Here’s a snapshot:
| California | 4 years | Yes | 4–5 years |
| Texas | 4 years | Yes (or equivalent) | 3–5 years |
| Florida | 4 years | Yes | 4–5 years |
| New York | 4–5 years | Yes | 5 years |

FAQ: Common Questions About Plumbing Certification
Q1: Can I get certified in plumbing online?
A: Not fully. While some classroom hours can be completed online (especially code review or safety training), hands-on experience is mandatory. No state grants a plumbing license based solely on online coursework.
Q2: How much does plumbing certification cost?
A: Total costs range from $0 (union apprenticeships) to $20,000+ (private trade schools). Exam fees, license applications, and tools add $500–$2,000. Many programs offer financial aid or employer reimbursement.
Q3: Do I need a license to do plumbing work?
A: Yes—in most states. Performing plumbing without a license can result in fines, legal liability, or voided insurance. Even minor repairs (like water heater installation) often require a licensed pro.
Q4: Can I transfer my plumbing license to another state?
A: Sometimes. States like Arizona and Florida have reciprocity agreements, but you’ll usually need to pass a state-specific code exam. Always verify with the new state’s licensing board.
Q5: What’s the difference between a certificate and a license?
A: A certificate (e.g., from a trade school) shows you completed training. A license is issued by the state and legally allows you to work. You need the license to practice professionally.
Q6: Is plumbing certification worth it?
A: Absolutely. The BLS reports plumbers earn a median salary of $60,090/year (2024), with top earners making over $100,000. Plus, demand is growing—employment is projected to rise 5% through 2032, faster than average.
Conclusion
So, how long does it take to get certified in plumbing? For most people, it’s a 2- to 5-year journey that blends hands-on work, classroom learning, and exams. While it requires commitment, the payoff is a stable, well-paid career with strong job security and opportunities for entrepreneurship.
