How to Increase Your Earnings as a Illinois Plumber
- Join a UA Local: Chicago-area plumbing locals (UA Local 130) offer top-tier wages plus benefits packages worth $40-50/hour on top of base pay. Union plumbers in Illinois earn significantly more than non-union counterparts.
- Get your Illinois plumbing license: Illinois requires state licensing through IDFPR. Licensed plumbers earn 25-40% more and can work independently across the state.
- Specialize in commercial/industrial: Chicago's commercial construction market (high-rises, hospitals, data centers) pays 20-30% above residential rates for qualified plumbers.
- Learn backflow prevention: Illinois requires annual backflow testing on commercial properties. Certified backflow testers can earn $75-150 per test, with spring season creating a lucrative side revenue stream.
- Target freeze damage season: Illinois winters create a surge in burst pipe repairs, frozen line thawing, and emergency plumbing calls from November through March. Emergency rates are 1.5-2x standard rates.
- Use technology to compete: Larger Chicago shops run ServiceTitan for dispatching across the metro's complex geography. Smaller shops use Housecall Pro to professionalize estimates and customer communication.
Cost of Living Considerations
Illinois cost of living is moderate to high, depending on proximity to Chicago. Chicago itself has high housing costs, but the suburban and downstate areas offer significantly better value. A $64,000 salary in Springfield or Peoria provides excellent purchasing power, while the same salary in Chicago requires careful budgeting. Illinois has a 4.95% flat state income tax and relatively high property taxes, which affect take-home pay. Union plumbers' benefit packages (health insurance, pension, annuity) add significant real compensation that doesn't show in salary figures.
How to Become a Plumber in Illinois
Illinois licenses plumbers through the Illinois Department of Financial and Professional Regulation (IDFPR). The state has apprentice, journeyman, and licensed plumber categories. The journeyman exam requires completion of an approved apprenticeship (typically 5 years through UA Local or IDFPR-approved program) or equivalent experience. The Licensed Plumber designation requires additional experience and examination. Chicago and Cook County have additional local licensing requirements that are among the strictest in the country.
Job Outlook for Illinois Plumbers
Illinois' plumbing job market is strong, particularly in the Chicago metro area. The city's aging infrastructure (some water mains date to the 1800s) creates sustained demand for replacement and repair work. The O'Hare modernization project, ongoing commercial development, and residential construction in the suburbs all drive demand. Illinois' plumbing workforce is aging (average age 52+), creating excellent opportunities for younger plumbers entering the trade. The Illinois Department of Employment Security projects 3-5% annual growth in plumbing jobs through 2030.
