Plumbing Business Sale Multiples 2026: What Buyers Actually Pay
Plumbing businesses sold for 1.8x to 11x earnings in 2026, with most owner-operated shops trading at 1.8x to 4x SDE and established $1M+ EBITDA companies clearing 5.5x to 7x EBITDA.
Platform-quality businesses with recurring revenue and a deep licensed-plumber bench reach 6x to 11x, and the rare multi-trade megadeals have hit 17x to 20x.
The multiple you actually get depends on three plumbing-specific factors: your service-versus-construction mix, your recurring revenue base, and who holds the master plumber license.
Here is what each tier sold for in 2026 and what moves your number up or down.
Plumbing Sale Multiples by Tier in 2026
Plumbing valuations break into clear tiers, each with its own buyer pool and earnings measure. Knowing your tier tells you who to market to and what to anchor on.
| Business Tier | Size | 2026 Multiple | Typical Buyer |
|---|---|---|---|
| Owner-operator | Under $500K SDE | 1.8x–4.0x SDE | Individual SBA buyers, search funds |
| Established service shop | $500K–$1M EBITDA | 4.0x–6.5x EBITDA | Regional consolidators, sub-platforms |
| Lower middle market | $1M+ EBITDA | 5.5x–7.0x EBITDA | PE-backed platforms |
| Platform-quality | $3M+ EBITDA | 6.0x–11.0x EBITDA | Roll-up anchors, PE platforms |
The spread inside each tier comes down to revenue quality. A shop with 30%+ recurring maintenance revenue typically clears 6x, while a purely transactional service business clears 4x to 5x.
SDE or EBITDA: Which Number Buyers Use
Smaller plumbing businesses are valued on SDE, which adds back the owner’s full compensation, benefits, and personal expenses run through the business.
Larger businesses are valued on EBITDA, which assumes a market-rate manager already sits in the owner’s seat.
The line sits around $500K in earnings. Buyers above roughly $2M in deal size will not accept an SDE-based valuation, because they are underwriting a business that runs without you.
This matters because the same business can look like a 3.5x SDE deal to an individual buyer and a 5.5x EBITDA deal to a platform.
The platform number is bigger, but only if your business can actually run without the owner.
The Master Plumber License Problem That Sets Plumbing Apart
This is the single biggest difference between selling a plumbing business and selling an HVAC business. The master plumber license is issued to an individual, not to the company, and it does not transfer in a sale.
If you are the only licensed qualifier, the buyer cannot legally operate the business the day after closing unless they hold or hire a qualifier.
Every sophisticated buyer prices that risk into their offer, or walks. Owners who are the sole qualifier routinely see a discount or a dead deal.
The fix is straightforward but takes time: qualify a backup master plumber on staff 12 or more months before going to market.
A business with a deep bench of licensed plumbers is a barrier to entry that a buyer cannot replicate in six months, and that depth is exactly what pushes you toward the top of your tier.
What Moves Your Plumbing Multiple Up or Down
Premium drivers
- 30%+ revenue from recurring maintenance and service agreements
- Service and repair mix over new construction (service trades at 1.5x to 2x the multiple of new-construction work)
- Multiple licensed plumbers on staff, not just the owner
- Commercial contract base (commercial plumbing earns a 1x to 1.5x premium over residential because B2B receivables are underwritable)
- Technician tenure of five-plus years and a working apprenticeship pipeline
Discount drivers
- Owner is the sole master plumber qualifier
- Customer concentration above 25% of revenue
- Project-based or new-construction revenue above 60% of the book
- Owner holds the key customer relationships personally
- High technician turnover in a market where licensed plumbers are scarce
Who Is Buying Plumbing Businesses in 2026
The most active buyers are multi-trade home services platforms that already run HVAC or electrical and add plumbing to cross-sell the same homeowner.
The math works because the customer who needs an AC repair today needs a water heater next month.
- PE-backed platforms: Apex Service Partners (Alpine Investors, with an Apollo minority stake, 75 brands), Wrench Group (Leonard Green, flagship Coolray), Sila Services (Goldman Sachs Alternatives), Champions Group (Blackstone).
- Franchise systems: Mr. Rooter (Neighborly, KKR-backed) and Benjamin Franklin Plumbing (Authority Brands).
- Strategic acquirers: Roto-Rooter (Chemed) and larger regional plumbing or mechanical companies buying for licensed technicians and commercial contracts.
- Individual and search-fund buyers: SBA-financed buyers acquiring single-market owner-operator shops.
For serious sponsor interest, the floor is roughly $3M in revenue and $500K in EBITDA.
Below that, you are talking to a sub-platform assembling several small shops into a cluster, or to an individual SBA buyer.
One honest note on the data: plumbing and HVAC are bundled together in most federal statistics and inside most of these platforms themselves. The same buyers chasing HVAC contractors are chasing plumbing contractors, frequently under one roof.

How to Estimate Your Plumbing Business Value
Start with your earnings base, pick the right measure for your size, then adjust for the drivers above.
- Calculate your SDE if you are under $500K in earnings, or your EBITDA if you are above it.
- Apply the base multiple for your tier from the table above.
- Adjust up for recurring revenue, licensed-plumber depth, and commercial mix.
- Adjust down for owner dependence, license concentration, and construction-heavy revenue.
- Pressure-test the result against your specific buyer pool, because a platform and an SBA buyer will price the same business differently.

Plumbing Sale Multiples FAQ
What multiple do plumbing businesses sell for in 2026?
Plumbing businesses sold for 1.8x to 11x earnings in 2026. Owner-operated shops under $500K SDE trade at 1.8x to 4x SDE, established companies with $1M+ EBITDA clear 5.5x to 7x, and platform-quality businesses with recurring revenue reach 6x to 11x. The number depends heavily on service mix, recurring revenue, and licensed-plumber depth.
Is my plumbing business valued on SDE or EBITDA?
Smaller owner-operated shops are valued on SDE, which adds back your full compensation and personal expenses. Larger businesses are valued on EBITDA, which assumes a market-rate manager already does your job. The line sits around $500K in earnings, and buyers above roughly $2M in deal size will not accept an SDE-based valuation.
Why does the master plumber license affect my multiple?
The master plumber license is issued to an individual, not the company, and it does not transfer in a sale. If you are the only licensed qualifier, the buyer cannot legally operate the day after closing, so they price that risk into the offer or walk. Qualifying a backup master plumber 12 or more months before going to market protects your multiple.
What gets a plumbing business a higher multiple?
Recurring maintenance revenue above 30%, a service-and-repair mix over new construction, multiple licensed plumbers on staff, a commercial contract base, and long technician tenure all push the multiple up. A shop with 30%+ recurring revenue typically clears 6x, while a purely transactional business clears 4x to 5x.
Who is buying plumbing businesses in 2026?
The most active buyers are multi-trade home services platforms that add plumbing to existing HVAC or electrical operations, including Apex Service Partners, Wrench Group, Sila Services, and Champions Group. Franchise systems like Mr. Rooter and Benjamin Franklin Plumbing, strategic acquirers like Roto-Rooter, and individual SBA buyers round out the market.
How do I estimate what my plumbing business is worth?
Start with your SDE if you are under $500K in earnings or your EBITDA if you are above it, apply the base multiple for your tier, then adjust up for recurring revenue, licensed-plumber depth, and commercial mix, and down for owner dependence and license concentration. A free professional valuation through Deal Prospectors can pressure-test the number against your actual buyer pool.
