Steamfitter Salary Guide
The Bureau of Labor Statistics reports a median annual wage of $61,550 for plumbers, pipefitters, and steamfitters — but this single number obscures a compensation structure that is fundamentally different from salaried professions [1]. Steamfitter pay is negotiated through collective bargaining agreements between United Association locals and signatory contractors, resulting in total compensation packages that include hourly wages, health insurance, pension contributions, annuity funds, and supplemental unemployment benefits. A journeyman steamfitter in New York City (UA Local 638) earns a total package exceeding $100 per hour — more than double the BLS median — while a non-union steamfitter in a rural Southern market may earn $22-$28/hour with minimal benefits. Understanding these variables is essential for evaluating offers and planning career decisions.
Key Takeaways
- Total compensation packages (wages + benefits) for union steamfitters range from $50-$105+/hour depending on local, with benefits often adding 40-60% on top of base wages
- The highest-paying markets are New York City, Boston, San Francisco, Chicago, and Seattle — all strong union markets with prevailing wage requirements on public projects
- Welding certifications (particularly ASME Section IX 6G on stainless steel and chrome-moly) create the most significant wage premiums among individual credentials
- Overtime is a major income variable — steamfitters on large commercial projects regularly work 50-60 hour weeks during peak construction phases, with time-and-a-half after 8 hours or 40 hours depending on the local agreement
- Non-union steamfitters earn 20-40% less in total compensation than their union counterparts in the same market, primarily due to the benefits gap (pension, annuity, health insurance)

| **Important context:** BLS data combines plumbers, pipefitters, and steamfitters into a single occupational category (47-2152). Steamfitters specifically tend to earn at or above the 75th percentile of this combined group because their work involves higher-pressure systems, more specialized welding, and stricter code compliance requirements. The BLS figures also represent base wages only — they do not include the employer-paid benefits (health insurance, pension, annuity) that constitute 40-60% of total union compensation packages. | ||
| ## Salary by Experience Level | ||
| ### Apprentice (Years 1-5) | ||
| Apprentice wages are calculated as a percentage of journeyman scale, increasing annually: | ||
| Apprentice Year | % of Journeyman Scale | Example (in $50/hr market) |
| --- | --- | --- |
| Year 1 | 50% | $25.00/hr |
| Year 2 | 55-60% | $27.50-$30.00/hr |
| Year 3 | 65-70% | $32.50-$35.00/hr |
| Year 4 | 75-80% | $37.50-$40.00/hr |
| Year 5 | 85-90% | $42.50-$45.00/hr |
| Benefits begin at indenture (day one of apprenticeship) in most UA locals, including health insurance and pension contributions — a significant advantage over non-union training programs where benefits may not begin for 90 days to a year [2]. | ||
| ### Journeyman (Years 5-10) | ||
| Full journeyman scale varies dramatically by local and region: | ||
| Market | Base Wage | Benefits |
| --- | --- | --- |
| New York City (Local 638) | $58-$62/hr | $42-$48/hr |
| Boston (Local 537) | $52-$56/hr | $38-$42/hr |
| San Francisco (Local 342) | $54-$58/hr | $36-$40/hr |
| Chicago (Local 597) | $50-$54/hr | $34-$38/hr |
| Seattle (Local 32) | $48-$52/hr | $32-$36/hr |
| Philadelphia (Local 420) | $46-$50/hr | $30-$34/hr |
| Denver (Local 208) | $38-$42/hr | $24-$28/hr |
| Atlanta (Local 72) | $32-$36/hr | $20-$24/hr |
| Dallas/Fort Worth | $28-$34/hr | $16-$22/hr |
| Rural/small market | $22-$30/hr | $10-$18/hr |
| Annual earnings for journeymen vary significantly based on hours worked. At $50/hour base wage: | ||
| - 40 hours/week, 50 weeks = $100,000 | ||
| - 50 hours/week (10 hrs OT at time-and-a-half) = $137,500 | ||
| - 55 hours/week with Saturday premium = $156,000+ | ||

| ### Foreman (Years 8-15) | ||
| Foremen receive a premium above journeyman scale — typically $3-$8/hour in additional base wages, with the same benefit package. Some contractors offer additional per diem, vehicle allowances, or project bonuses. | ||
| **Annual range:** $95,000-$145,000 depending on market and overtime availability. | ||
| ### Superintendent / General Foreman (Years 12-20+) | ||
| Superintendents are often salaried (exempt) or paid on a guaranteed-hours basis. Compensation includes base salary, company vehicle, phone, and often project-completion bonuses. | ||
| **Annual range:** $110,000-$165,000+ in major markets. | ||
| ### Project Manager / Estimator | ||
| Office-based roles at mechanical contracting firms. Salary plus bonus structure. | ||
| **Annual range:** $90,000-$155,000 depending on firm size and project portfolio. | ||
| ## Salary by Specialization | ||
| Certain specializations command premiums above standard journeyman scale: | ||
| Specialization | Premium Above Scale | Why |
| --- | --- | --- |
| Pharmaceutical clean steam (orbital TIG) | $5-$15/hr | Requires orbital welding cert, ASME BPE knowledge, cleanroom protocols |
| Nuclear piping | $8-$20/hr | Requires security clearance, NDE familiarity, nuclear QA documentation |
| Chrome-moly welding (power generation) | $3-$10/hr | Requires 6G certification on P91/P22 chrome-moly — difficult to pass |
| Medical gas installation | $2-$5/hr | Requires ASSE 6010 certification, clean room protocols |
| District heating (underground) | Market rate | No premium per se, but projects are large-scope with consistent overtime |
| Maintenance/facilities (non-union) | Varies | Often lower hourly but includes salary benefits, PTO, stability |

| ## Salary by State / Region | ||
| ### Highest-Paying States (Annual Mean Wage, BLS) | ||
| Rank | State | Annual Mean |
| --- | --- | --- |
| 1 | Illinois | $82,430 |
| 2 | Alaska | $80,910 |
| 3 | New York | $79,920 |
| 4 | Massachusetts | $78,260 |
| 5 | New Jersey | $76,840 |
| 6 | Oregon | $75,670 |
| 7 | Minnesota | $74,890 |
| 8 | Washington | $74,550 |
| 9 | Hawaii | $73,410 |
| 10 | California | $72,980 |
| Source: BLS OES, May 2023 [1] | ||
| **Note:** These BLS figures represent base wages only. In union-dense states (Illinois, New York, Massachusetts), total compensation packages are 40-60% higher than the reported wage figures. Additionally, states with prevailing wage laws (requiring union-scale pay on public projects) inflate overall averages because a significant portion of steamfitting work is on public institutional projects (hospitals, schools, government buildings). | ||
| ### Lowest-Paying States | ||
| Southern and rural states with weaker union presence report the lowest wages: | ||
| State | Annual Mean | Hourly Mean |
| --- | --- | --- |
| Mississippi | $41,280 | $19.85 |
| Arkansas | $42,910 | $20.63 |
| Alabama | $43,850 | $21.08 |
| South Carolina | $44,220 | $21.26 |
| West Virginia | $44,680 | $21.48 |
| The pay gap between highest and lowest states ($82,430 vs. $41,280) is nearly 2:1. However, cost-of-living differences partially offset this — a steamfitter earning $42,000 in Mississippi has lower housing costs than one earning $80,000 in Illinois. The more meaningful comparison is total package value adjusted for local cost of living. | ||
| ## Union vs. Non-Union Compensation | ||
| The union/non-union wage gap in steamfitting is among the largest in the construction trades because of the specialized nature of the work and the strength of UA collective bargaining in major markets. | ||
| Component | Union (Major Market) | Non-Union (Same Market) |
| --- | --- | --- |
| Base hourly wage | $48-$62 | $28-$40 |
| Health insurance | Employer-paid, family coverage | Often employee-contribution or individual only |
| Pension | Defined benefit, employer-funded ($5-$15/hr contribution) | 401(k) with 0-4% match |
| Annuity / 401(k) supplement | $3-$8/hr employer contribution | Included in 401(k) above |
| Paid vacation | 1-4 weeks (funded through supplemental dues) | 1-2 weeks typically |
| Training | JATC-funded, continuous education | Employer-dependent |
| **Total package** | **$80-$110+/hr** | **$35-$55/hr** |
| Source: UA benefit trust fund reports and BLS Employee Benefits Survey [2][5] | ||
| The primary non-union advantage is employment flexibility — non-union steamfitters may have more direct relationships with employers and less downtime between projects in markets where union work is seasonal. In "right-to-work" states, the non-union market share is larger, meaning more available positions (though at lower pay). | ||
| ## Overtime and Premium Pay | ||
| Overtime is a major component of steamfitter earnings. High-pressure steam work often requires tight construction schedules (systems must be operational before building occupancy), creating consistent overtime opportunities. | ||
| **Standard overtime provisions (vary by local agreement):** | ||
| - Time-and-a-half (1.5x) after 8 hours per day or 40 hours per week | ||
| - Double time (2x) for Sundays, holidays, and sometimes Saturdays (varies by local) | ||
| - Shift differential: second shift (afternoon/evening) adds $1-$5/hour; third shift (overnight) adds $2-$8/hour | ||
| **Shutdown and turnaround premiums:** Steamfitters working scheduled shutdowns at hospitals, power plants, or industrial facilities often work extended hours (10-12 hour shifts, 6-7 days per week) for 2-6 week durations. A journeyman earning $55/hour base can gross $3,500-$5,500/week during shutdowns. | ||
| ## Benefits Breakdown | ||
| For union steamfitters, the benefits package represents a substantial portion of total compensation — often 40-60% on top of base wages: | ||
| Benefit | Typical Employer Contribution | Annual Value |
| --- | --- | --- |
| Health & welfare (medical, dental, vision) | $10-$18/hr | $20,000-$37,000 |
| Pension (defined benefit) | $5-$15/hr | $10,000-$31,000 |
| Annuity / supplemental retirement | $3-$8/hr | $6,000-$16,000 |
| Apprenticeship training fund | $1-$3/hr | $2,000-$6,000 |
| Supplemental unemployment benefit | $0.50-$2/hr | $1,000-$4,000 |
| Industry promotion / LMCT | $0.25-$1/hr | $500-$2,000 |
| A journeyman in a major market with a $55/hour base wage and $40/hour benefit package receives total compensation equivalent to a $95/hour rate — or approximately $198,000 annualized at 40 hours/week. Including overtime, total annual compensation value can exceed $250,000 [2]. | ||
| ## Factors That Increase Steamfitter Pay | ||
| 1. **Welding certifications.** ASME Section IX qualifications — particularly 6G position on stainless steel and chrome-moly — directly increase your value. Orbital TIG welding certification for pharmaceutical and semiconductor work commands the highest premiums ($5-$15/hour above scale). | ||
| 2. **Geographic mobility.** Willingness to travel to high-wage markets or take travel assignments through the UA dispatch system opens access to the best-paying projects. Per diem payments ($50-$100+/day for food and lodging) further increase effective earnings. | ||
| 3. **Specialization in high-demand sectors.** Healthcare, pharmaceutical, and data center construction are expanding sectors with strong demand for qualified steamfitters. Building a project resume in these areas increases demand for your services. | ||
| 4. **Advancement to foreman/superintendent.** The management premium (10-25% above scale) compounds with overtime to produce the highest W-2 earnings in the trade short of business ownership. | ||
| 5. **Prevailing wage projects.** Public construction projects in states with prevailing wage laws pay Davis-Bacon or state-determined rates, which are typically set at or near union scale. Even non-union contractors must pay prevailing wages on these projects [6]. | ||
| ## Frequently Asked Questions | ||
| ### How much do steamfitters make per year? | ||
| Annual earnings vary dramatically based on market, union affiliation, overtime, and specialization. The BLS reports a national median of $61,550, but this understates actual earnings for skilled union journeymen. A union journeyman in a major market working steady (2,000 hours/year) earns $100,000-$125,000 in base wages alone. With overtime (2,200-2,500 hours), annual wages reach $130,000-$175,000. Add the value of employer-paid benefits ($40,000-$80,000/year), and total compensation packages range from $140,000-$250,000+ in top markets [1][2]. | ||
| ### Do steamfitters make more than plumbers? | ||
| Generally yes. Within the UA, steamfitters and plumbers share similar base wage scales in most locals, but steamfitters access more overtime-intensive projects (hospital shutdowns, industrial turnarounds) and command welding premiums that plumbers typically do not. The BLS combines both trades in the same occupational category, but industry surveys consistently show steamfitters earning 5-15% more in total annual compensation due to project type and overtime patterns [1]. | ||
| ### What is the highest-paying steamfitter specialization? | ||
| Nuclear piping and pharmaceutical clean steam (orbital TIG welding) are the two highest-paying specializations. Nuclear pipers earn premiums of $8-$20/hour above standard journeyman scale due to the security clearance requirements, documentation burden, and limited qualified workforce. Pharmaceutical orbital TIG welders earn $5-$15/hour premiums due to the difficulty of orbital welding certification and the high quality standards of ASME BPE work [4]. | ||
| ### How does steamfitter pay compare to other construction trades? | ||
| Among the building trades, steamfitters rank at or near the top in total compensation — comparable to elevator constructors and electricians (inside wiremen), and above sheet metal workers, ironworkers, and carpenters. The UA trades (steamfitters, plumbers, pipefitters, sprinkler fitters) collectively represent one of the highest-compensated trade groups in construction [1]. | ||
| ### Is steamfitter pay keeping up with inflation? | ||
| UA collective bargaining agreements typically negotiate annual wage increases of 2-5% over 3-year contract periods. In recent years (2022-2024), many locals have negotiated increases of 4-6% annually due to the construction labor shortage, which has disproportionately affected skilled specialty trades like steamfitting. Real wage growth (adjusted for inflation) has been positive in most major markets [3]. | ||
