Plumbing Businesses Sell for More.
Here's Why.
The licensing barrier to entry gives plumbing companies a structural valuation premium. Average multiples range from 3.0x to 5.0x SDE, but the spread depends on license depth, team composition, and revenue mix.
The License Premium
Why plumbing businesses command higher prices than most service companies
In most service industries, the barriers to entry are low. A cleaning company, a moving company, a general handyman service - anyone with a truck and some motivation can start competing with you next week. That accessibility pushes multiples down because buyers know that new competitors can erode market share quickly.
Plumbing is different. You can't legally perform plumbing work without licensed plumbers. Obtaining a journeyman license takes three to five years of supervised work. A master plumber license requires additional years and a rigorous exam. This creates a genuine regulatory moat around your business that directly translates into higher valuations.
The national shortage of licensed plumbers compounds this advantage. The Bureau of Labor Statistics projects plumbing jobs growing faster than average through 2032, while the existing workforce is aging. Every licensed plumber on your team represents years of training that a buyer can't replicate quickly. This isn't just a talking point. It's a quantifiable premium that shows up in every comparable transaction.
The bottom line: a plumbing business with a strong licensed team is selling a government-sanctioned competitive advantage. Buyers pay more because the license structure protects their investment from rapid competitive erosion.
License Transfer & Regulatory Value
The single biggest deal risk in any plumbing acquisition is the license question. Addressing it early prevents surprises at closing.
License Audit
- --Inventory all licenses held (master, journeyman, specialty)
- --Identify which employees vs. the owner hold licenses
- --Verify renewal status and any pending disciplinary issues
- --Document continuing education compliance
Transfer Requirements
- --Research state-specific transfer rules for your jurisdiction
- --Determine if stock sale vs. asset sale affects license continuity
- --Identify municipal permits and contractor registrations that need updating
- --Timeline: some states process in weeks, others take months
Deal Structure
- --Owner stays as qualifying licensee during transition (6-12 months typical)
- --Employment agreements for licensed staff to prevent departure at closing
- --Escrow holdback tied to successful license transfer completion
- --Contingency plan if a key licensed plumber leaves within 12 months
Key insight: Businesses where the owner is the only license holder typically sell for 15-25% less. If you're 2-3 years from selling, hiring an additional licensed plumber now is one of the highest-ROI moves you can make.
Team Depth Analysis
The number and type of licensed professionals on staff is the single most important factor after revenue in determining your plumbing business multiple.

Owner fully replaceable
PE and strategic buyer interest likely
Service Mix Impact on Value
Not all plumbing revenue is created equal. Here's how buyers rank different revenue streams by quality and predictability.
High margins, non-deferrable demand, premium pricing
Predictable recurring revenue, strong retention rates
Steady demand driven by aging infrastructure and homeowner needs
Higher ticket but project-based and sensitive to housing market conditions
Cyclical, competitive bidding, payment delays, builder dependency
Quality scores reflect how each revenue type impacts valuation multiples, not absolute revenue potential.
The SBA Financing Advantage
Plumbing businesses are some of the most SBA-friendly acquisitions in the small business market. This matters because SBA eligibility directly expands your buyer pool, which drives up competition and ultimately your sale price.
An SBA 7(a) loan allows a buyer to acquire your business with as little as 10% down. That means a $500,000 plumbing business only requires $50,000 from the buyer. Compare that to conventional financing requiring 20-30% down, and you can see why SBA eligibility opens the door to far more qualified buyers.
Why Plumbing Businesses Qualify Easily:
- Predictable, demonstrable cash flow
- Hard assets (vehicles, equipment, tools)
- Established customer base with repeat business
- Essential service with recession-resistant demand
- Licensing creates a defensible competitive position
