Wisconsin Plumber License Requirements

To practice as a plumber in Wisconsin, the state licensing board requires 5,297 documented education or training hours, a passing score on the State Journeyman Plumber Exam examination, and 4 years of supervised work experience. A criminal history background check is also part of the application. Applicants must be at least 18 years old. The regulation sits under Wisconsin's professional licensing framework, which classifies training as "Apprenticeship Program".

Upfront cost is $118, with renewal running $101 on a 1-year cycle. Maintaining the license requires 8 hours of continuing education per 1-year cycle, an ongoing cost applicants often underestimate when budgeting the career.

Reciprocity is available: Journeyman licenses rarely reciprocal — check state board. Compared to the profession-wide pattern, the numbers above should be cross-checked against other states before relocating — licensing cost, training hours, and exam requirements vary enough that a different state may cut thousands of dollars and months of training from the path. The state board, not this page, is the final authority; verify every field below with the official regulator before you pay fees or enroll in training.
