The Short Answer
Most plumbing companies sell for roughly 2x to 4.5x Seller's Discretionary Earnings (SDE), or 4x to 6x EBITDA at scale. A residential service plumber earning $200,000 in SDE typically sells for $500,000–$800,000. Companies weighted toward service, repair, and recurring commercial contracts — rather than one-time new-construction plumbing — sit at the top of that range.
As with HVAC, buyers reward predictability. Emergency service calls, drain-cleaning route work, and commercial maintenance accounts all make earnings more durable and the multiple higher.

How Plumbing Companies Are Valued
For most plumbing businesses under about $1M in earnings, value is a multiple of SDE — net profit plus owner compensation, add-backs, depreciation, and non-recurring costs. Larger firms with layered management are valued on EBITDA. The methodology is identical to other trades; what differs is the risk profile buyers assign to your specific revenue mix.
New-construction plumbing is cyclical and tied to a handful of builders. Service and repair plumbing is recession-resistant — pipes break in good times and bad — so a service-heavy company earns a premium multiple for the same dollar of profit.
Plumbing Valuation Multiples by Profile
| Company profile | Typical multiple | Why |
|---|---|---|
| Solo owner-operator | 1.5x–2.5x SDE | Business is the owner; hard to transfer |
| Residential service + repair, small crew | 2.5x–3.5x SDE | Recurring demand, trained techs |
| Service-heavy with commercial contracts | 3.5x–4.5x SDE | Recurring revenue, diversified accounts |
| Mid-market, $1M+ EBITDA | 4.0x–6.0x EBITDA | Management team, scale, roll-up interest |
What Drives a Plumbing Company's Value Up or Down
What pushes the multiple up
- Service, repair, and drain work over new construction — recession-resistant and higher margin
- Recurring commercial or property-management accounts
- 24/7 emergency service reputation and online reviews
- Licensed journeymen who will stay through transition
- Owner in a management role, not running every call
What drags the multiple down
- Dependence on one or two general contractors
- Heavy new-construction concentration — lumpy and cyclical
- Owner holds the master license and does the estimating
- Undocumented pricing and cash jobs that vanish in diligence
Plumbing Company Values in Southern California
Southern California's older housing stock — much of Los Angeles, the San Fernando Valley, and Ventura County has homes 40+ years old — drives steady repipe, sewer, and repair demand. That underlying service volume supports strong valuations for established local plumbers. A California C-36 plumbing contractor's license and clean workers' comp records are checked closely in diligence, especially on SBA-financed deals, so confirm your license transfers before you list.
Example: Service vs. New Construction
A plumbing company doing $250,000 in SDE on 75% new-construction work for two builders might sell for about 2.5x — $625,000. Reposition that same profit around residential service, drain routes, and a dozen recurring commercial accounts, and the same business sells for 4x — $1,000,000. Buyers pay for the revenue they can count on next year.
Frequently Asked Questions
How much is a plumbing company worth?
Most plumbing companies sell for 2x to 4.5x Seller's Discretionary Earnings (SDE), or 4x to 6x EBITDA at scale. A residential service plumber earning $200,000 in SDE typically sells for $500,000 to $800,000, with service-heavy and commercially diversified companies commanding the higher end.
What multiple do plumbing businesses sell for?
Solo operators sell for about 1.5x to 2.5x SDE, established residential service companies for 2.5x to 3.5x, and service-heavy firms with recurring commercial accounts for 3.5x to 4.5x SDE. Mid-market companies with $1M+ EBITDA can reach 4x to 6x EBITDA.
Is a service plumbing business worth more than new construction?
Yes. Service and repair plumbing is recession-resistant and higher margin, so buyers assign it a higher multiple than cyclical, builder-dependent new-construction work at the same profit level.
What lowers the value of a plumbing company?
Concentration in one or two general contractors, heavy new-construction exposure, an owner who holds the license and does all estimating, and undocumented cash work that cannot be verified during due diligence.
