Joe Plumber Salary and Job Outlook
The median annual wage for plumbers, pipefitters, and steamfitters was $59,880 in May 2023, with the lowest 10 percent earning less than $33,300 and the highest 10 percent earning more than $101,190, according to the U.S. Bureau of Labor Statistics BLS occupational outlook. Employment of plumbers is projected to grow 2 percent from 2023 to 2033, slower than the average for all occupations, but about 40,000 openings are expected each year due to replacement needs.
Pay varies by state and metro area, with plumbers in Alaska, Illinois, and Minnesota earning above the national median, while those in southern and rural states tend to earn less. Union plumbers in areas such as New York and San Francisco often earn more than nonunion workers because of collective bargaining agreements that set wage floors and benefits.
Licensing, Training, and Career Path
Most states require plumbers to be licensed, and requirements typically include completing an apprenticeship of 4 to 5 years that combines paid on-the-job training with classroom instruction in blueprint reading, local codes, and safety. The Department of Labor reports that apprentices earn a percentage of journey-level wages and progress as they gain hours and pass exams.
Journeyman and Master Plumber Stages
After finishing an apprenticeship, a worker can take the journeyman license exam, and after several years of documented experience, they may sit for the master plumber exam. Master plumbers can pull permits, design systems, and supervise other tradespeople, which often leads to higher earnings and independent contracting opportunities.
Top Employers and Industry Trends
Major employers of plumbers include plumbing and heating contractors, self-employed workers, and building equipment contractors. The construction of new residential and commercial buildings, along with retrofitting older structures for water efficiency and green standards, continues to drive demand for skilled plumbers.
Technology is changing the trade, with digital estimating tools, smart home systems, tankless water heaters, and high-efficiency boilers requiring additional training. Contractors who invest in these skills and maintain strong safety records often win more commercial and municipal projects.
