How to Become a Plumber in 2026: Apprenticeship, Licensing, and Pay

Published July 2026  ·  11 min read

Becoming a licensed plumber takes four to five years and costs almost nothing, because a plumbing apprenticeship pays you from the first day rather than charging tuition. At the end of it, the trade has the highest median wage of the four major building trades — $63,800 a year, $30.67 an hour.

This is the practical version: what the steps actually are, what each one pays, what it costs, and where the path is harder than the brochures suggest. Wage figures come from the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey for May 2025 (SOC 47-2152), pulled from the BLS API. For the full state-by-state pay picture, see our plumber salary guide.

The Path, Start to Finish

There are five steps, and only one of them is optional.

1. Finish high school or get a GED. Algebra and geometry matter more than you would guess — pipe sizing, slope, and offsets are applied trigonometry. Shop classes and welding help.
2. (Optional) Trade school certificate. Six to twelve months, roughly $3,000–$15,000. Not required and not a substitute for on-the-job hours, but it improves placement and some programs credit a few hundred hours toward the apprenticeship.
3. Get into a registered apprenticeship. The real entry point. Union route via a UA local's Joint Apprenticeship and Training Committee; non-union via PHCC, ABC, or directly with a contractor. Apply to several at once — intake is capped.
4. Complete ~8,000 hours plus classroom work. Four to five years, paid throughout, with wage steps roughly every 1,000 hours. Classroom is typically two evenings a week.
5. Pass the journeyman exam and get licensed. State or local code exam. From here you can work unsupervised — and you are at the median wage.

Then, if you want the top of the trade, a master licence follows after another two to five years as a journeyman.

The Licensing Ladder and What Each Tier Earns

Plumbing is one of the most consistently licensed trades in the country. The titles and hour thresholds are set state by state, but the structure is close to universal:

The distinction that catches people out is journeyman versus master. A journeyman licence lets you do the work. A master licence lets you sell the work — pull permits, sign off designs, supervise apprentices' licensed hours, and qualify a business for its contractor licence. That is why the master exam is the real gate, and why the biggest earnings jump sits on the other side of it.

What You Earn While You Train

Apprentice pay is a percentage of the local journeyman rate, stepping up as you bank hours. Applied to the national median of $63,800 ($30.67/hr), a common progression looks like this:

Because the percentage applies to local scale, where you apprentice matters more than when you started. A first-year apprentice in DC on roughly $45,459 out-earns a fully licensed journeyman in Arkansas, where the median is $48,660. The apprentice wage progression calculator will run this for your state and period.

What It Actually Costs

This is the part that separates the trades from a degree. The apprenticeship itself has no tuition — the sponsor funds the instruction and you are paid a wage throughout. What you pay for:

• Hand tools and boots: roughly $500–$2,000 over the first year, often built up gradually
• Textbooks and materials: a few hundred dollars a year
• Licensing exam fees: typically $100–$400 per exam, varying by state
• Optional trade school first: $3,000–$15,000
• Optional certifications later: backflow prevention and ASSE 6010 medical gas are each short courses with strong returns

Net position after four to five years: licensed, no debt, earning around the national median, and having been paid the whole way through. That is a materially different financial starting point from a graduate of the same age.

Where the Apprenticeship Is Worth Most

Because everything scales off local journeyman rates, the state you train in sets both your apprentice pay and your ceiling. The ten highest and five lowest, by BLS median:

Modelled figures from BLS medians, not quoted apprenticeship rates — your local wage sheet is the authority. Useful for the decision people actually face, which is whether it is worth training one state over.

The Parts Nobody Puts in the Brochure

Four things worth knowing before you commit four years.

• Hours are not guaranteed. You bank hours only when there is work. A slow year stretches a four-year apprenticeship into five, and that is common rather than unusual.
• The classroom is real work. Two evenings a week of code and theory on top of a full physical week. This is where most of the attrition happens, not on the job site.
• It is hard on your body. Crawl spaces, trenches, overhead pipe, heavy fixtures. Knees, shoulders, and backs are the usual casualties, and service plumbers take on-call rotations.
• Wages plateau at journeyman. Turnout puts you at $63,800. Getting to $85,110 or $108,420 requires specialising into industrial pipefitting, adding certifications, or going into business — not simply staying longer.

None of which is an argument against the trade. It is an argument for going in with a plan for what you do after turnout, which is the decision most plumbers make by default rather than deliberately.

The Step Most Plumbers Underrate

The largest earnings jump in this trade is not a certification. It is the move from working for a plumbing company to running one. A master licence plus a bond and insurance is all the law requires; the reason more journeymen do not take the step is that the business side — estimating, quoting, collecting, scheduling — is a genuinely different skill from the trade itself.

It is also the part that is now largely a tooling problem rather than a talent one. Quoting a repipe with estimating software and financing the homeowner can accept on the spot is a different conversation from handing over a handwritten number. If you are hiring, note that stepped apprentice wages and certified payroll are exactly what construction payroll software handles and a general accounting package does not.
