Step-by-step path
Register as an apprentice
Register with Washington State Department of Labor and Industries (L&I) before starting work. This is required to legally accumulate supervised hours toward your journeyman qualification. Some states charge a small registration fee.
Accumulate 8,000 hours of supervised experience
Work under a licensed journeyman or master pipefitter. This takes approximately 4 years at full-time hours. Your employer is required to verify your hours when you apply for the journeyman exam.
Pass the journeyman licensing exam
The exam covers United Association (UA) Journeyman Card requirements and state-specific rules. Exam fee is $80. Most candidates study 4-8 weeks using a state-approved prep guide before sitting for the test.
Apply for your journeyman license
Submit your application to Washington State Department of Labor and Industries (L&I) after passing the exam. License fee is $80. Processing typically takes 2-4 weeks. Your employer's verification of your hours is required at this stage.
Renew annual
Your Washington license renews annual. Renewal fee is $80. Some states require continuing education at renewal. Always renew on time to avoid a lapse in licensure.

Union vs. independent path
Pipefitters have one of the strongest union presences of any trade. The UA (United Association) represents pipefitters alongside plumbers and HVAC workers. Both paths lead to the same state license — the difference is in how you accumulate your hours and the employment benefits you receive during training.
| Union (UA) | Non-union / independent | |
|---|---|---|
| Training program | 5-year UA apprenticeship, tuition-free | Employer OJT (industrial employers) |
| Wages during training | Starting at ~50% journeyman scale, increasing annually | Varies significantly by employer |
| Benefits | Full union benefits (health, pension, annuity) | Employer-dependent |
| Job placement | UA union hall dispatch to industrial contractors | Self-directed; industrial employers recruit directly |
| Welding certification | UA program includes welding certification tracks | Candidate's own responsibility |
| Post-license mobility | UA card recognized by signatory contractors nationally | Depends on state reciprocity |
Transferring your license from another state
Pipefitter license reciprocity varies by state. Some states have reciprocal agreements for journeyman-level pipefitters. UA card holders working for signatory contractors have de facto national mobility. Contact the state licensing board to verify if your credentials transfer.
If you currently hold a pipefitter license in another state and want to work in Washington, contact the Washington Dept. of Labor and Industries (L&I) directly before applying. Bring documentation of your current license, your work history, and your exam scores — many boards will expedite review for out-of-state applicants with equivalent credentials.
Plumbers and pipefitters both work under the UA union umbrella but on different systems. See the Plumber license guide for Washington for comparison.
Industrial facilities hire both pipefitters and electricians — see the Electrician license guide for Washington.
