If you’re in your third year of a plumbing apprenticeship in Colorado—or considering one—you’re probably wondering: “How much does a 3rd year plumber make in Colorado?” It’s a smart question. After all, you’re investing time, sweat, and skill into a demanding trade, and knowing your earning potential helps you plan your future with confidence. Whether you’re budgeting for tools, saving for a home, or weighing career options, this guide breaks down exactly what you can expect to earn—and how to earn more.
What Is a 3rd Year Plumber?
A 3rd year plumber is typically an apprentice who has completed two full years of on-the-job training and classroom instruction under a licensed journeyman or master plumber. In Colorado, plumbing apprenticeships usually last 4–5 years, so the third year marks a critical midpoint—where your responsibilities increase, your skills deepen, and your pay should reflect that growth.
During this stage, you’re likely:
- Installing and repairing pipes, fixtures, and drainage systems
- Reading blueprints and building codes
- Assisting with inspections and permitting
- Working independently on simpler tasks under supervision
This growing autonomy directly impacts your earnings.
Average Salary for a 3rd Year Plumber in Colorado (2026 Data)
According to the U.S. Bureau of Labor Statistics (BLS) and state-level wage surveys from the Colorado Department of Labor and Employment (CDLE), here’s what 3rd-year plumbing apprentices in Colorado typically earn:
| Experience Level | Hourly Wage Range | Annual Earnings (Full-Time) |
|---|---|---|
| 1st Year Apprentice | $16 – $19 | $33,000 – $39,500 |
| 3rd Year Apprentice | $22 – $27 | $45,800 – $56,200 |
| Journeyman Plumber | $28 – $38+ | $58,000 – $79,000+ |
💡 Note: These figures assume 40 hours/week and 50 working weeks/year. Overtime, union membership, and geographic location can significantly shift these numbers.
For example, a 3rd-year apprentice in Denver might earn closer to $26/hour, while someone in rural areas like Montrose or Sterling may start around $22/hour due to lower cost-of-living adjustments.
How Location Affects Pay in Colorado
Colorado’s plumbing wages vary widely by region. Urban centers offer higher pay but come with steeper living costs. Here’s a quick comparison:
| City/Area | Avg. 3rd-Year Hourly Wage | Cost of Living Index* |
|---|---|---|
| Denver Metro | $25 – $27 | 112 (High) |
| Colorado Springs | $23 – $25 | 105 (Moderate-High) |
| Fort Collins | $24 – $26 | 108 |
| Grand Junction | $21 – $23 | 98 (Below Avg) |
| Pueblo | $20 – $22 | 94 (Low) |

👉 Pro Tip: If you’re early in your career, consider working in high-demand urban zones like Denver or Boulder to maximize hourly rates—even if rent is higher. The net gain often outweighs the extra housing cost.
Union vs. Non-Union Pay: What’s the Difference?
In Colorado, union-affiliated plumbers (often through UA Local 125 in Denver or UA Local 525 in Colorado Springs) typically earn 10–20% more than non-union peers during their apprenticeship.
Union Benefits Include:
- Structured pay increases every 6 months
- Health insurance and retirement plans (even as an apprentice)
- Guaranteed work hours and safety protections
- Free or subsidized training
However, union programs are competitive and may require entrance exams or waiting lists. Non-union paths offer more flexibility but less wage security.
According to the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry, union apprentices in Colorado saw a 5.2% wage increase in 2025 due to new collective bargaining agreements.
How to Increase Your Earnings as a 3rd-Year Plumber
You’re not stuck with base pay. Here’s how to boost your income during your third year:
- Work Overtime
Many contractors offer time-and-a-half for weekend or emergency calls. Just 5 extra hours/week at $33/hour adds $8,500+ annually. - Get Certified in Specialized Skills
Learn backflow prevention, medical gas piping, or solar water heating. These certifications can add $3–$6/hour to your rate. - Join a High-Volume Contractor
Companies handling commercial or multi-family projects often pay more than small residential shops. - Track Your Hours Accurately
Ensure every training hour counts toward your journeyman license. Missing paperwork can delay your promotion—and raise. - Ask for a Mid-Year Review
If you’ve taken on leadership (e.g., mentoring 1st-years), use it as leverage for a raise.
Career Outlook: Is Plumbing Worth It in Colorado?
Absolutely. Colorado faces a growing shortage of skilled tradespeople, especially in construction-heavy regions. The BLS projects 11% job growth for plumbers nationwide through 2034—faster than average—and Colorado’s growth is even higher due to population influx.
Moreover, once you become a licensed journeyman (after ~4–5 years), your earning potential jumps dramatically. Some Colorado journeymen earn $90,000+ with overtime and side jobs.
And if you go further? Master plumbers who own businesses can clear $120,000–$180,000/year in metro areas.
