How Plumbing Businesses Are Valued
Plumbing companies have become increasingly attractive acquisition targets as private equity firms expand their home services portfolios beyond HVAC. The same characteristics that make HVAC valuable — essential service, recurring revenue potential, fragmented market — apply to plumbing.
Small Plumbing Companies (Under $3M Revenue)
Most small plumbing businesses sell for 2.0-3.5x SDE. A plumbing company with $1.5M in revenue and $300K in SDE would sell for $600,000 to $1,050,000. At this size, the buyer is typically another plumber or a local competitor looking to acquire the customer base and licensed workforce.
Mid-Size and PE-Attractive Companies
Plumbing companies with $3M+ revenue, a team of 10+ licensed plumbers, and service agreements attract PE add-on interest at 5-8x EBITDA. The key is having infrastructure that scales — dispatch systems, a service manager, fleet management, and recurring maintenance contracts.
What Drives Plumbing Company Value
Licensed plumbers on staff are the most valuable asset. The skilled trades shortage means a company with 8 licensed, retained plumbers is worth more than the same revenue with 8 constantly-churning subcontractors.
Service agreements and recurring revenue — plumbing companies that have transitioned from purely emergency/project work to recurring maintenance contracts (backflow testing, drain maintenance, water heater service plans) command 1-2x higher multiples.
Commercial vs. residential mix matters. Commercial plumbing is higher-margin but more project-dependent. Residential service is more fragmented but offers better recurring revenue potential. Buyers generally prefer a mix.
Geographic density — a plumbing company serving a tight geographic area has better route efficiency and brand recognition than one spread across a wide territory. PE buyers specifically look for density because it drives technician productivity.
