Plumbing Industry Statistics 2026: Market Size, Revenue & Trends

Plumbing is among the most essential and recession-resistant trades in the U.S. economy. When pipes leak, drains clog, or water heaters fail, homeowners and businesses have no choice but to call a plumber. The industry has expanded steadily over the past decade, supported by new construction, aging infrastructure, and the growing complexity of plumbing systems in modern homes. In 2026, the U.S. plumbing industry stands at a critical juncture — demand is strong, labor is short, and the contractors who answer the phone fastest are winning the most work.

Market Size and Revenue Statistics

The U.S. plumbing contracting industry generated an estimated $130 billion in revenue in 2026, up from approximately $105 billion in 2020. Residential plumbing accounts for about 52% of total market revenue, with commercial construction, institutional, and industrial plumbing making up the balance. The residential segment is driven by repair and replacement demand — water heaters, supply lines, drain systems, and fixtures — while commercial work tends to involve larger contracts and longer project cycles.

Plumbing Contractor and Business Statistics

There are approximately 125,000 plumbing contracting businesses in the United States as of 2026. The industry is highly fragmented — 72% of plumbing businesses have fewer than 10 employees, and about 28% are solo operators. This fragmentation means most plumbing markets are locally competitive, with dozens or hundreds of contractors serving the same geographic area. In this environment, the contractor who answers the phone first has a decisive advantage.

Employment and Wage Statistics

The Bureau of Labor Statistics reports approximately 480,000 plumbers, pipefitters, and steamfitters employed in the United States in 2026. The median annual wage for plumbers is $61,550, with the top 10% earning over $100,000. Plumbing employment is projected to grow 2% through 2032 — slower than average, but the industry faces a significant shortage of skilled workers as older plumbers retire faster than new apprentices enter the trade.

Call Volume and Missed Call Statistics for Plumbers

Phone calls are the primary booking channel for plumbing services. Research by Invoca and ServiceTitan consistently shows that 70% to 78% of plumbing customers prefer to call rather than book online, especially for anything involving an emergency or diagnostic service. Yet the plumbing industry has one of the worst call answer rates of any home service trade. Industry data suggests 62% of plumbing calls go unanswered during business hours — and after hours, the number climbs above 85%.

Plumbing Job Ticket and Revenue Statistics

Average plumbing job ticket values vary dramatically by service type. Simple service calls — a running toilet, a leaking faucet, a slow drain — average $150 to $350. Moderate repairs such as water heater replacement, garbage disposal installation, or drain clearing average $400 to $900. Major work — sewer line repair or replacement, repipes, leak detection, and water damage restoration — averages $2,000 to $8,000. Emergency calls carry a 1.5x to 2x premium, making after-hours emergency plumbing among the highest-margin work available.

Plumbing Emergency Statistics

Emergency plumbing represents a disproportionate share of revenue for plumbing businesses. Research by the Insurance Information Institute finds that water damage — the primary driver of emergency plumbing calls — is the second most common homeowners insurance claim in the U.S. The average water damage claim is $11,650. Plumbers who position themselves as the go-to emergency provider in their market — and who answer calls 24/7 — capture not just the repair revenue but often the restoration referral revenue as well.

Infrastructure and Replacement Demand Statistics

Aging infrastructure is a massive driver of plumbing demand in 2026. The American Society of Civil Engineers (ASCE) gives U.S. drinking water infrastructure a grade of C- in its 2025 report card. An estimated 6 billion gallons of treated water is lost daily to leaks in distribution systems. Municipally, lead pipe replacement programs are generating substantial commercial plumbing work. In residential markets, homes built before 1970 with galvanized steel or original copper plumbing are reaching the end of their serviceable life — a replacement wave that will sustain plumbing demand for the next 15 to 20 years.

Customer Behavior and Booking Statistics

Plumbing customers are decisive and impatient. When a pipe bursts, they call. When the call goes to voicemail, 86% hang up without leaving a message and immediately dial the next plumber. A study by Lead Connect found that response time is the single strongest predictor of whether a plumbing lead converts — you are 21 times more likely to convert a lead if you respond within five minutes than within 30 minutes. For plumbing businesses, this means phone availability is not just convenient — it is the primary conversion lever.

Technology and AI Adoption in Plumbing

Technology adoption in plumbing lags behind HVAC but is accelerating. As of 2026, approximately 35% of plumbing businesses with more than $500K in revenue use field service management software (ServiceTitan, Housecall Pro, Jobber). AI-powered call answering adoption is lower — around 22% among mid-size operators — but growing at 40% annually as contractors see direct ROI from capturing calls they previously missed.

Plumbing Business Profitability Statistics

Well-run plumbing businesses achieve net profit margins of 10% to 20% on service and repair work. Installation and remodeling work carries lower margins (8% to 15%) due to material costs and competitive bidding. Businesses that invest in maintenance agreements — annual or semi-annual plumbing inspections — generate more predictable revenue and higher customer lifetime values. The average plumbing maintenance customer is worth 3.2x a one-time service customer over a five-year period.
