A business generating $180,000 in SDE with four licensed plumbers beyond the owner and commercial service contracts is typically worth $450,000 to $720,000.

What a Plumbing Business Is Worth in 2026
A plumbing business is worth between 2.5x and 4.0x its SDE โ seller's discretionary earnings. A plumbing business generating $180,000 in SDE with a strong team of licensed plumbers and commercial accounts is worth $450,000 to $720,000 depending on technician depth, commercial revenue percentage, and fleet condition.
Most plumbing businesses sell in the 2.8x to 3.3x range. Reaching 3.5x or above requires three or more licensed plumbers running independent service territories, commercial property management accounts generating predictable call volumes, and documentation of repeat customer rates demonstrating brand loyalty.

What Drives Plumbing Business Value
Licensed plumber depth is the most critical value driver. State plumbing licenses require apprenticeship hours, journeyman examinations, and continuing education โ creating a genuine supply constraint on qualified technicians. A plumbing business where the owner is the only licensed plumber faces buyer concern about licensing continuity and service capacity during transition. Three or more licensed plumbers beyond the owner signals an operation that continues generating revenue regardless of what happens to the selling owner.
Commercial accounts with property management companies, apartment complexes, schools, and hospitals generate $500 to $5,000 per service call versus $150 to $400 for residential calls, and multi-unit relationships that produce consistent annual call volumes.
Service and repair plumbing โ fixing leaks, replacing water heaters, clearing drains โ generates recurring call volume from an established customer base. New construction plumbing depends on builder relationships and housing market conditions. Buyers value service and repair revenue more than construction revenue because it is independent of housing cycles.
How to Use This Number
Plumbing owners planning to sell should focus on retaining licensed technicians, developing commercial property management relationships, and shifting revenue mix toward service and repair. These three changes consistently move plumbing valuations toward the top of the range.
