Valuation Multiples
What Plumbing Businesses Are Selling For
| Revenue Size | Method | Multiple Range |
|---|---|---|
| Under $1M earnings | SDE | 1.68x – 2.97x |
| $1M+ earnings | EBITDA | 2.43x – 4.45x |
| Larger / manager-led | EBITDA | 4x – 7x+ |
Plumbing companies are valued on Seller’s Discretionary Earnings (SDE) for smaller, owner-operated businesses — adding your salary and personal expenses back to net profit. Once a company has a management team and earnings above $1M, buyers typically shift to EBITDA. Plumbing businesses at the higher end of that range tend to have documented systems, recurring service agreements, and low owner dependency. Cervit’s AI valuation agent calculates both and explains which applies to your situation.
What Drives Your Multiple
What Drives Plumbing Business Value
Service vs. New Construction Mix
Plumbing companies built on recurring service and repair work — residential maintenance, commercial service contracts — are valued higher than those dependent on new construction installs. New construction revenue moves with housing starts; service revenue does not. Buyers pay for predictability.
Service Agreements and Recurring Revenue
Long-term service contracts with commercial clients, property managers, or facilities give buyers a revenue base they can project forward. Even a modest base of recurring plumbing service agreements meaningfully improves the multiple a buyer will pay.
Fleet and Equipment Condition
Plumbing companies carry real asset value in vehicles and equipment. Well-maintained, documented fleets reduce operational risk for buyers and can positively affect valuation — particularly when financed equipment is paid down before a sale.
Owner Dependency
If calls come to your cell phone, you write the estimates, and clients ask for you by name — that’s owner dependency, and buyers discount for it. A business that runs through a lead plumber or ops manager is transferable. One that runs through the owner is a job, not a business.

FAQ
Common questions about plumbing business valuation.
Most owner-operated plumbing companies sell for 1.68x–2.97x SDE. Companies with service agreements, low customer concentration, and a team that doesn’t rely on the owner can reach the higher end — or shift to an EBITDA multiple of 4x–7x for larger businesses.

Recurring service revenue, clean financials, a team that can operate without the owner, and a diversified customer base. The less exposed the business is to any single client relationship or revenue source, the more a buyer will pay.
