Plumber Shortages Hit 45% of Home Builders; Labor Costs Up 4.2% as Firms Invest in Training

The Cost of Scarcity

Labor costs have climbed 4.2% over the past 12 months in the builder segment, a direct consequence of tight supply. This upward pressure on wages reflects broader market dynamics: plumbers are in demand, and employers are competing for a limited talent pool. The median plumber salary now stands at $63,800 annually—well above the national median of about $51,000—making the trade an attractive career path on paper, yet positions remain hard to fill.

The challenge extends beyond wages. Nearly 88% of construction firms with open trades positions reported that recruitment has become as difficult or harder compared to the prior year, indicating that salary increases alone are not solving the problem.

What This Means for Service Businesses

For HVAC, plumbing, appliance-repair, and electrical contractors operating independently or as small firms, these trends create both opportunity and operational risk. The tightening labor market suggests strong customer demand—plumber employment is projected to grow 7 percent from 2025 to 2035, with roughly 42,000 openings annually. However, that same scarcity makes it harder to scale operations, take on additional jobs, or replace departing staff quickly.

Contractors working on residential jobs should anticipate scheduling pressures and may be able to command higher service rates as demand outpaces supply. At the same time, the cost of acquiring and retaining technicians will likely rise.

Training as a Retention Tool

In response to these headwinds, 35% of contractors have started or increased spending on training and professional development. This shift suggests that firms are recognizing investment in existing staff—whether through apprenticeships, certifications, or skill advancement—as a hedge against turnover and a way to build internal capacity.

For smaller service operators, this may mean allocating budget toward worker development, whether through trade schools, manufacturer training, or mentorship programs. The median age of plumbers stands at 40.2 years, slightly below the all-worker average, indicating that the workforce is not aging out as rapidly as some sectors—but the demographic still skews toward middle-aged workers, underscoring the need for a pipeline of younger talent.

Addressing the Diversity Gap

Women comprise only 3.1% of employed plumbers, pipefitters, and steamfitters, a stark underrepresentation that points to an untapped labor pool. Contractors seeking to differentiate recruitment efforts and expand their talent base might consider targeted outreach to underrepresented groups, both to address immediate staffing needs and to contribute to long-term workforce diversity.

The plumbing industry's small-firm structure—81.7% of construction payroll establishments have 10 or fewer employees—means most service businesses operate independently or in tight teams. In this environment, each hire has outsized impact. A single departure can disrupt scheduling and revenue, making retention strategies particularly urgent.

Takeaway for Business Owners

The combination of rising demand, labor cost inflation, and widespread recruitment difficulty suggests that service business owners should prioritize workforce stability through competitive compensation, training investment, and intentional retention practices. The shortage is not temporary cyclical phenomenon but reflects structural imbalances in supply and demand that are projected to persist through 2035. Planning for higher labor costs and longer hiring cycles should factor into pricing strategy and operational forecasting.
