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

Published July 2026  ·  Updated October 2026

What the 2025 Handbook Says About Plumber Jobs

The Occupational Outlook Handbook page for plumbers, pipefitters, and steamfitters, fetched 2026-10-29, says they held about 510,600 jobs in 2025. The median annual wage was $63,800 in May 2025, or $30.67 an hour. The lowest 10 percent earned less than $44,150. The highest 10 percent earned more than $108,420. Employment is projected to grow 7 percent from 2025 to 2035, much faster than average, a change of 34,500 jobs. About 42,000 openings are projected each year, on average, over the decade. The pay tab says the wage survey does not include self-employed workers.

The same page says the largest employers were plumbing, heating, and air-conditioning contractors at 65 percent, self-employed workers at 8 percent, and government, heavy and civil engineering construction, and manufacturing at 3 percent each. Industry medians in May 2025: government $71,660, manufacturing $65,770, heavy and civil engineering construction $63,270, and plumbing, heating, and air-conditioning contractors $63,010. The construction-trades group median on that page is $58,150. All occupations: $50,980.

Most learn through a 4- or 5-year apprenticeship. Apprentices typically receive 2,000 hours of paid on-the-job training, plus some technical instruction, each year. Technical instruction includes safety, local plumbing codes and regulations, and blueprint reading. Most states and some localities require plumbers to be licensed. Although requirements vary, states and localities often require 2 to 5 years of experience and an exam before plumbers work independently. Some states require master plumber status to obtain a plumbing contractor's license. The handbook says apprentices earn less than fully trained workers and that pay increases as they learn more. It does not print a starting percent, a tool price, or an exam fee.

How apprentice pay is discussed without inventing a percent is the apprentice wage guide. Flat-rate pricing for the work itself is the plumbing flat rate pricing guide. The cost of employing a person, once a wage is known, is the contractor labor burden calculator. The software that holds the crew and the job is plumbing contractor software.

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.

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. The handbook says some people also attend a vocational-technical school. It does not print a tuition. A school is not a substitute for the on-the-job hours.
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 local medians differ, where you work matters. The handbook fetched on 2026-10-29 does not print a starting percent of scale, so this page no longer multiplies a state median by one. The apprentice wage progression calculator is a separate planning tool. The Arkansas median on the state table below is the page's earlier BLS figure, not a new fetch.

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:

The handbook does not print a price for tools, books, an exam, or a trade school. It does say the apprenticeship includes paid on-the-job training, and that most states require a license, often after 2 to 5 years of experience and an exam. Write the fee your state board prints. Do not borrow a national range this page no longer shows.

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.
