Why Getting Licensed Matters
Let’s be honest—plumbing isn’t something people leave to chance. Clients want someone they can trust, and a plumbing license tells them you’re the real deal. Is it worth the effort? Yes, and here’s why:
- Stay Legal: Most states require a license to work as a plumber. Without one, you could face hefty fines or even lose the right to work.
- Earn More: Licensed plumbers—especially those with a master license—can pull in between $75,000 and $100,000 a year, depending on experience and location.
- Secure Better Jobs: From government contracts to large commercial projects, the best gigs go to licensed professionals.
- Build Trust: A license shows clients and employers you’ve mastered the trade and follow strict safety standards.
The Three Levels of Plumbing Licenses
Plumbing isn’t a one-size-fits-all profession. Your license reflects your experience and the type of work you can take on:
- Apprentice License
This is where it all begins. As an apprentice, you’ll learn the ropes under a licensed plumber while completing classroom training. It’s the perfect mix of theory and hands-on experience. - Journeyman License
After completing your apprenticeship and passing an exam, you can work independently. With a journeyman license, you’re free to tackle projects on your own. - Master Plumber License
Ready to lead? A master license qualifies you to manage teams, take on complex jobs, and even run your own plumbing business. It’s the top tier of the trade.
6 Steps to Getting Your Plumbing License
Licensing rules vary by state, but most plumbers follow these six steps to get licensed:
1. Meet the Education Basics
Most states require a high school diploma or GED as a starting point. Many plumbers also attend trade schools to get ahead. These programs cover essentials like math, blueprint reading, and plumbing fundamentals—skills you’ll use daily.
2. Find an Apprenticeship Program
Think of apprenticeships as on-the-job training with a paycheck. These programs, usually 2–5 years long, combine classroom lessons with practical experience.
Pro Tip: Check out local unions, trade associations, or contractors in your area to find a program that suits your goals.
3. Log Those Work Hours
Most states require between 4,000 and 8,000 hours of supervised work before you can apply for a license.
Keeping track of these hours can feel like a job in itself, but tools like Invoice Fly make it easy to document your work and stay organized.
4. Pass Your Licensing Exam
Licensing exams test your knowledge of plumbing codes, safety standards, and system design. Some states also require hands-on assessments to prove your skills in real-world scenarios.
Pro Tip: Study smarter: Use state-specific guides and practice tests to prepare.
5. Submit Your Application
Gather your documents—proof of education, work hours, and exam results—and submit them to your state’s licensing board. Fees range from $50 to $500, depending on where you live.
6. Keep Your License Current
Most licenses need renewing every 1–2 years, and some states require continuing education. Staying up-to-date ensures you remain compliant, knowledgeable and an expert in your trade.
