Plumbers, Pipefitters & Steamfitters Salary in Wisconsin

Plumbers, pipefitters, and steamfitters in Wisconsin earn a median salary of $78,510 annually, or $37.75 per hour—significantly higher than the national median of $62,970. With Wisconsin's lower cost of living (0.932 factor), this translates to $84,238 in purchasing power. Entry-level workers (10th percentile) start around $48,960, while experienced professionals (90th percentile) can earn $114,460. Pay varies significantly based on specialty, with steamfitters and pipefitters typically earning more than residential plumbers. Union membership through the United Association (UA) often provides higher wages, better benefits, and more consistent work. Milwaukee and Madison metro areas generally offer the highest salaries due to industrial demand and prevailing wage projects. The field requires physical stamina and problem-solving skills, with work involving installation, repair, and maintenance of pipe systems for water, gas, steam, and other materials. Wisconsin's manufacturing base, including paper mills and food processing facilities, creates strong demand for industrial pipefitters and steamfitters, while population growth drives residential plumbing needs.

Wisconsin requires plumbers to complete a state-approved apprenticeship and obtain a journeyman license. The typical path involves a 4-5 year apprenticeship program combining 8,000-10,000 hours of on-the-job training with classroom instruction. United Association (UA) locals offer the most comprehensive programs, including Local 75 (Milwaukee), Local 434 (Madison), and Local 400 (Green Bay). Non-union apprenticeships are available through independent contractors and the Associated Builders and Contractors (ABC). Wisconsin requires apprentices to register with the Department of Safety and Professional Services (DSPS). After completing apprenticeship requirements, candidates must pass the state journeyman plumber examination covering codes, safety, and installation practices. Some municipalities require additional local licenses. Apprentices typically start at 40-50% of journeyman wages, progressing to full pay upon completion. Technical colleges like Milwaukee Area Technical College and Western Technical College offer pre-apprenticeship programs that can provide an advantage when applying. Veterans may receive credit for military experience. The state recognizes licenses from some other states through reciprocity agreements, though additional testing may be required.

The $65,500 gap between Wisconsin's 10th percentile ($48,960) and 90th percentile ($114,460) reflects significant earning potential based on specialization and experience. Entry-level residential service plumbers typically start near the 10th percentile, while experienced industrial steamfitters and pipefitters often reach the 90th percentile. Union membership is a major factor—UA members generally earn 20-30% more than non-union workers. Geographic location within Wisconsin matters significantly, with Milwaukee and Madison areas offering salaries 15-25% above rural markets. Industrial specialists working in power plants, refineries, and manufacturing facilities command premium wages, often reaching the 75th percentile ($100,710) or higher. Commercial new construction and service work typically falls in the middle range. Overtime opportunities, especially for emergency service calls and industrial shutdowns, can substantially boost annual earnings. Master plumbers and those running their own businesses often exceed the 90th percentile through markup on materials and services.
