How Much Does a Fully Qualified Plumber Earn?

Thinking about a career in plumbing—or just curious what a licensed pro really makes? You’re not alone. Many Americans are exploring skilled trades as stable, high-demand alternatives to traditional college paths. How much does a fully qualified plumber earn? The answer might surprise you—especially when you factor in overtime, self-employment, and regional differences. In this guide, we’ll break down real earnings, geographic variations, and what it takes to maximize your income in this essential profession.

What Is the Average Salary for a Fully Qualified Plumber in the US?

According to the U.S. Bureau of Labor Statistics (BLS), the median annual wage for plumbers, pipefitters, and steamfitters was $60,090 as of May 2023. This translates to about $28.89 per hour.

But “median” only tells part of the story. Top earners—especially those with decades of experience, specialized certifications (like gas fitting or medical gas systems), or who run their own businesses—can make well over $100,000 annually.

Which States Pay Plumbers the Most?

Location dramatically impacts plumbing income. High cost-of-living states often offer higher wages—but so do areas with labor shortages or booming construction sectors.

Here are the top 5 highest-paying states for plumbers (BLS, 2023):

1. Illinois – $86,220
2. Alaska – $83,520
3. Massachusetts – $81,970
4. Hawaii – $81,450
5. New Jersey – $80,630

Conversely, states like Mississippi and South Dakota report average salaries closer to $45,000—highlighting how geography can swing earnings by $30K–$40K annually.

💡 Pro Tip: If you’re mobile and willing to relocate, targeting high-demand, high-wage states can significantly accelerate your career earnings.

How Does Certification Affect a Plumber’s Earnings?

Not all plumbers are created equal. In most U.S. states, you must progress through three stages:

1. Apprentice (paid training, 4–5 years)
2. Journeyman (licensed to work independently)
3. Master Plumber (can run a business, supervise others)

Each step unlocks higher pay. For example:

• Apprentices typically earn 40–60% of a journeyman’s wage—but with no student debt.
• Journeymen earn the baseline $60K median.
• Master plumbers often earn 20–40% more, especially if they manage teams or handle commercial/industrial projects.

Special certifications—like backflow prevention, medical gas piping, or solar water heating—can add $5,000–$15,000 to your annual income by qualifying you for niche, high-stakes jobs.

Self-Employed vs. Employed Plumbers: Who Earns More?

This is where the real earning potential shines.

While employed plumbers enjoy steady paychecks and benefits, self-employed plumbers often earn significantly more—if they manage their business well.

Pros & Cons Comparison:

Many plumbers start employed, build a client list, then launch their own venture. With platforms like Angi (Angie’s List) or HomeAdvisor, digital marketing makes it easier than ever to attract local customers—even without a storefront.

What Factors Influence a Plumber’s Salary?

Beyond location and licensure, several variables affect income:

• Industry: Residential plumbers typically earn less than those in commercial, industrial, or government sectors.
• Overtime: Emergency calls (nights/weekends) often pay 1.5x–2x standard rates.
• Union Membership: Union plumbers (e.g., through UA – United Association) often earn 10–20% more with better benefits.
• Economic Conditions: Construction booms = more plumbing jobs. Recessions may slow new builds but increase repair work (people fix instead of move).

📊 Real-World Example: A master plumber in Chicago who specializes in high-rise building maintenance and works weekends for emergency leaks reported $112,000 in 2024—$32K above the state average.

How to Maximize Your Plumbing Income: 5 Actionable Steps

1. Get Your Master License – Opens doors to supervision, bidding on large contracts, and starting a business.
2. Specialize Early – Focus on high-demand niches: water treatment, green plumbing, or renovation retrofits.
3. Go Mobile & Digital – Use scheduling apps (e.g., Jobber) and run Google Ads targeting “emergency plumber near me.”
4. Track Every Dollar – Use accounting software (like QuickBooks Self-Employed) to maximize tax deductions.
5. Upskill Continuously – Take OSHA safety courses or get certified in tankless water heaters—skills that justify premium pricing.

FAQ Section

Q1: Do plumbers really make six figures?

Yes—especially master plumbers who own businesses in high-cost or high-demand areas. With overtime and emergency calls, earnings of $100,000–$130,000 are realistic for top performers.

Q2: How long does it take to become a fully qualified plumber?

Most states require 4–5 years of apprenticeship (combining classroom learning and on-the-job training) before you can take the journeyman exam. An additional 1–2 years of experience is usually needed for master licensure.

Q3: Is plumbing a good career in 2025 and beyond?

Absolutely. The BLS projects 5% job growth from 2022–2032—faster than average—driven by infrastructure upgrades, aging pipes, and new construction. Plus, plumbing can’t be outsourced or automated easily.

Q4: What’s the difference between a journeyman and a master plumber?

A journeyman can work independently but can’t pull permits or run a business in most states. A master plumber has passed advanced exams and can supervise teams, design systems, and operate a licensed plumbing company.

Q5: Can I earn more as a plumber than with a college degree?

In many cases, yes—and without the debt. The average plumbing apprentice graduates debt-free and earns while learning. By age 25, many licensed plumbers out-earn bachelor’s degree holders in fields like communications or sociology.

Q6: Are plumbing salaries affected by recession?

Less than most jobs. While new construction may slow, emergency repairs and maintenance are recession-resilient—people always need working toilets, hot water, and leak fixes.

Conclusion

So, how much does a fully qualified plumber earn? While the national median hovers around $60,000, your actual income depends on location, certifications, business acumen, and specialization. With the right strategy, plumbing offers a clear path to $80K–$130K+—without student loans or a four-year degree.
