Illinois Plumbing: A Trade Built on Infrastructure and Opportunity

Few trades are as recession-resistant as plumbing, and in Illinois, that stability comes paired with some of the strongest wages in the Midwest. From the high-rise towers reshaping Chicago's skyline to the aging water mains running beneath the city streets, plumbers in Illinois are in constant demand -- and they are compensated accordingly.

The state's plumbing landscape is defined by its union strength, particularly in the Chicago metropolitan area where United Association Local 130 has negotiated wages and benefits that put Illinois plumbers among the top earners in the country. But the opportunity extends well beyond the union halls of Chicago. Downstate plumbers benefit from hospital construction, municipal water system upgrades, and industrial plant maintenance that keeps the work flowing year-round.

Whether you are weighing a career in the trades, exploring your earning potential as a journeyman, or considering how to advance to master plumber licensure, this guide offers a comprehensive look at plumber salaries across Illinois, the forces driving demand, and the strategies that separate high earners from average ones.

Plumber Salary in Illinois: By the Numbers

The Bureau of Labor Statistics reports a national median annual wage for plumbers, pipefitters, and steamfitters of approximately $61,550. Illinois plumbers, especially those in union positions in the Chicago area, regularly exceed this figure by a substantial margin.

Here is how wages typically break down across experience levels and job types in Illinois:

• Apprentice Plumbers (Year 1-2): Starting wages in the $20 to $26 per hour range. Union apprentices receive wage increases with each passing year of their five-year program.
• Apprentice Plumbers (Year 3-5): As skills develop, apprentice wages rise toward 70 to 90 percent of journeyman scale, often reaching $38 to $46 per hour in the final year.
• Journeyman Plumbers (Union, Chicago Metro): UA Local 130 journeyman wages exceed $50 per hour on base. Total compensation including health, pension, and annuity funds pushes effective hourly compensation toward $80 to $95.
• Journeyman Plumbers (Non-Union): Wages typically run $35 to $50 per hour depending on employer size, geographic market, and specialty. Annual earnings of $65,000 to $90,000 are common.
• Pipefitters and Steamfitters: These cousins of the plumbing trade -- who work on industrial piping, HVAC piping, and process systems -- often command even higher wages. Chicago-area pipefitters can earn $100,000 to $130,000 annually with overtime.
• Master Plumbers: Those holding master plumber licenses who run their own businesses or lead project teams can earn $90,000 to $150,000 or more depending on volume and specialty.

UA Local 130: Setting the Wage Standard in Chicago

United Association of Plumbers and Steamfitters Local 130 is one of the flagship union locals in the plumbing industry and a dominant force in the Chicago construction market. With collective bargaining agreements that set wage floors well above market rate, Local 130 membership represents a significant financial advantage for plumbers who pursue it.

The union's current journeyman base rate sits above $50 per hour, but that number only tells part of the story. Employer contributions to health and welfare, pension, and training funds substantially increase the total hourly cost to contractors -- and the total benefit to members. A Local 130 journeyman who works consistently can expect:

• Base hourly wages that typically reach or exceed $52 per hour
• Employer-funded health insurance covering the member and family
• Defined benefit pension with contributions that build year over year
• Annuity fund contributions that supplement retirement savings
• Paid vacation fund contributions
• Access to one of the best apprenticeship training programs in the country

The training program affiliated with Local 130 is a JATC (Joint Apprenticeship Training Committee) program that combines classroom instruction at the training center with on-the-job learning under experienced journeymen. By the end of the five-year program, graduates are fully qualified journeyman plumbers with years of real-world experience and zero educational debt.

Chicago's Infrastructure Investment: What It Means for Plumbers

Chicago is in the midst of a massive, multi-decade infrastructure renewal that is generating consistent work for plumbers across every sector. Three categories stand out as particularly significant:

Water Main Replacement and Utility Work

Chicago's water distribution system includes thousands of miles of aging pipes, many dating back more than a century. The city has committed to an accelerated lead pipe replacement program, targeting the elimination of lead service lines connecting the water mains to residential properties. This effort alone is creating years of sustained work for plumbers and utility contractors operating in the city and its suburbs.

Hospital and Healthcare Construction

Major healthcare systems including Rush University Medical Center, Northwestern Medicine, Advocate Aurora, and the University of Illinois Hospital have all undertaken significant expansion and renovation projects in recent years. Healthcare construction is among the most plumbing-intensive work in the commercial sector, with complex requirements for medical gas systems, sterile water delivery, and high-capacity waste systems.

High-Rise Residential and Mixed-Use Development

Chicago's construction boom continues along the lakefront, in the West Loop, and in suburban growth corridors. Each new high-rise tower represents months of work for plumbing crews roughing in and trimming out complex plumbing systems serving hundreds of units. The volume of this work has been substantial throughout the 2020s and shows no sign of slowing.

Regional Salary Differences Across Illinois

While Chicago commands the highest wages, plumbers across Illinois have access to solid earning opportunities regardless of where they are based:

• Chicago and Northern Suburbs: Highest wages. Union journeymen average $85,000 to $120,000 in total annual compensation. Overtime during busy seasons can push top earners past $140,000.
• Rockford: Industrial plumbing work is steady here. Journeyman wages typically run $55,000 to $80,000, with union positions at the higher end.
• Peoria: Caterpillar and related manufacturing create industrial plumbing demand. Wages are competitive, often in the $60,000 to $85,000 range for experienced plumbers.
• Springfield: State government and healthcare are the dominant employers here. Commercial plumbing work is steady, with wages ranging from $50,000 to $75,000.
• Champaign-Urbana: University construction and healthcare expansion drive consistent plumbing work. Wages align with mid-state averages at $50,000 to $72,000.
• Southern Illinois: Lower wages reflecting the regional economy, but solar and agricultural facility construction are adding new opportunity. Typical range $45,000 to $65,000.

How to Become a Licensed Plumber in Illinois

Illinois requires plumbers to hold a state plumber license, which is administered by the Illinois Department of Public Health. Unlike some other trades, plumbing licensure in Illinois is a statewide system (though Chicago has additional local requirements). The key steps are:

• Complete a Registered Apprenticeship: A five-year apprenticeship registered with the Illinois Department of Labor satisfies the experience requirement for journeyman licensure. Both union (JATC) and non-union (ABC) apprenticeships exist.
• Accumulate Work Hours: Illinois requires 8,000 hours of on-the-job plumbing experience under a licensed plumber.
• Pass the Illinois Plumber License Exam: The state administers a written exam covering the Illinois Plumbing Code, plumbing theory, and applied knowledge.
• Obtain a Journeyman Plumber License: This license allows you to perform plumbing work under the supervision or permit of a licensed master plumber.
• Advance to Master Plumber: After two or more years as a licensed journeyman, you can sit for the master plumber exam. Master licensure allows you to pull permits and supervise projects.

Specializations That Maximize Plumber Earnings in Illinois

Not every plumbing role pays the same. These specializations can meaningfully boost your earnings:

• Pipefitting and Industrial Piping: Pipefitters who work on process piping, steam systems, and mechanical systems in industrial settings earn among the highest wages in the trade.
• Medical Gas Systems: Installing and certifying medical gas systems in hospitals requires specialized training and certification. The work is precise, the stakes are high, and the pay reflects that.
• Fire Suppression Systems: Fire sprinkler fitters in Illinois are licensed separately, but plumbers with this certification add a profitable specialty.
• Green Plumbing and Water Efficiency: LEED-certified projects and water reclamation systems require plumbers familiar with sustainable design principles.
• Backflow Prevention: Illinois requires certified backflow prevention device testers for cross-connection control programs. This certification opens an additional revenue stream.

Job Outlook for Plumbers in Illinois

The Bureau of Labor Statistics projects plumber employment to grow 6 percent nationally through the early 2030s, on par with the average for all occupations. In Illinois, several structural factors suggest the local market will outperform this baseline. Chicago's infrastructure renewal alone guarantees years of sustained work. The state's aging building stock requires constant maintenance and code-compliance upgrades. And new construction activity, while cyclical, continues at a pace that keeps plumbing demand elevated.

Perhaps most importantly, the retirement wave hitting the trades is creating significant opportunity. Many experienced journeyman and master plumbers in Illinois are approaching retirement age, and the pipeline of new entrants is not large enough to fully replace them. This supply constraint is both pushing wages higher and giving newly qualified plumbers unusually strong career leverage.
