What Is My Plumbing Company Worth?

TLDR: Plumbing companies typically sell for 2.9x to 5.0x EBITDA or 2.2x to 3.5x SDE. With a median asking price of $795,000 and median SDE near $287,000, most owner-operated plumbing businesses fall in the $600K–$1M range. Recurring service contracts, technician retention, and low owner dependency are the biggest value drivers.

If you've built a plumbing company from the ground up, you probably have a sense of what it produces every year. What you may not know is how a buyer translates that number into an offer—and why two plumbing businesses with similar revenue can sell for very different prices.

This guide walks you through exactly how plumbing companies are valued: the metrics buyers use, the multiples that are realistic in today's market, and the specific factors that push your number higher or lower.

Understanding SDE (Seller Discretionary Earnings)

If you've talked to a business broker, you've almost certainly heard the term SDE—Seller Discretionary Earnings. It's the most common starting point for valuing smaller owner-operated businesses, and plumbing companies are no exception.

SDE is what the business earns for you, the owner. It starts with net profit and adds back your salary, personal benefits, one-time expenses, non-cash charges like depreciation, and other perks you run through the business. The result is a number that reflects the full financial benefit an owner-operator takes home from the business each year.

For plumbing companies currently on the market, the median SDE is approximately $287,400. That's a meaningful income stream—and it's what brokers and sellers typically use as the basis for initial pricing conversations.

Regalis Capital note: SDE is a useful and widely used metric, but it's worth understanding how it fits into the broader valuation picture. Buyers—especially private equity groups and strategic acquirers—often recast the numbers using a different standard before making an offer.

Understanding EBITDA

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It's the metric that serious buyers, lenders, and institutional investors use to evaluate a business's underlying operating performance.

Here's how it differs from SDE in practice: while SDE adds back the owner's full compensation, EBITDA replaces it with a market-rate salary for someone who would manage the business in the owner's place. This makes EBITDA a more standardized number—one that allows buyers to compare your plumbing company against others regardless of how much the current owner pays themselves.

Think of SDE as the answer to "what does this business produce for me as the owner?" and EBITDA as the answer to "what would this business produce for any professional operator?" Both are valid lenses. SDE gives you an honest view of your current cash flow; EBITDA is the bridge to how institutional buyers underwrite a deal.

For a plumbing company generating strong margins with a management layer in place, EBITDA can actually be higher than you'd expect relative to SDE—because market-rate management salaries are often lower than what an owner-operator has been paying themselves.

Plumbing Company EBITDA Valuation Range

Based on current market data, plumbing companies are selling at the following EBITDA multiples:

Example: A plumbing company with $400,000 in EBITDA trading at 3.8x would produce a valuation of approximately $1.52 million.

These are buyer-favored ranges drawn from actual market transactions. Not every business commands the top of the range—and representing your company accurately from the start leads to better outcomes than pricing high and negotiating down.

Plumbing Company SDE Valuation Range

For owner-operated plumbing businesses—particularly those under $1M in asking price—SDE multiples remain the most common valuation framework among brokers and individual buyers.

Current market data shows plumbing companies trading at 2.2x to 3.5x SDE.

At the median SDE of $287,400, a business in the middle of this range (around 2.9x) would carry an asking price near $833,000—consistent with the national median asking price of $795,000 currently observed across active listings.

The SDE range is capped at 3.5x to reflect realistic buyer expectations. Multiples above this threshold are unusual for plumbing businesses and typically require institutional buyers, significant scale, or exceptional recurring revenue profiles.

What Drives Value Up or Down in a Plumbing Company

Two plumbing businesses can have identical revenue and still sell for very different multiples. Here's what separates them:

Value-enhancing factors: - Recurring service contracts. Annual maintenance agreements, water heater service plans, and HVAC/plumbing bundled contracts create predictable revenue that buyers pay a premium for. A plumbing company with 30%+ recurring revenue is a fundamentally different asset than one that lives and dies by dispatch calls. - Low owner dependency. If the business runs without you dispatching jobs, managing technicians, and handling callbacks, buyers see a business—not a job. A working foreman or operations manager in place is a significant value driver. - Technician retention and depth. Licensed plumbers are hard to find. A stable crew with low turnover, including at least one journeyman or master plumber who isn't the owner, directly reduces transition risk. - Strong online reputation. Google reviews, response rates, and local search rankings are increasingly scrutinized during due diligence. A 4.5+ star average with hundreds of reviews signals market position. - Clean financials. Three years of well-documented P&Ls, job-level profitability data, and clean separation between business and personal expenses accelerates buyer confidence and reduces renegotiation risk.

Value-reducing factors: - Heavy owner involvement in day-to-day operations or customer relationships - Customer concentration (one or two commercial accounts making up 30%+ of revenue) - Aging vehicles and equipment with deferred maintenance - Short lease terms on shop or yard space with no renewal option - Revenue tied to one or two geographic service areas with no demonstrated growth path

How Buyers Evaluate Plumbing Companies

When a serious buyer reviews your plumbing company, they're not just looking at the top-line numbers. Here's what they dig into during due diligence:

Revenue quality. Is revenue growing, flat, or declining? How much is residential versus commercial? How much is repeat versus new customers? Recurring service agreements are weighted heavily.

Margin stability. Plumbing businesses typically operate on 15–25% EBITDA margins. Buyers will benchmark your margins against industry norms and probe for any cost creep—particularly labor costs as a percentage of revenue.

Technician licensing and compliance. Are your plumbers properly licensed? Are permits being pulled correctly? Any outstanding violations or complaints with the state licensing board will surface and can derail a deal.

Vehicle and equipment condition. Buyers price in the capital they'll need to spend post-close. Deferred fleet maintenance or outdated equipment becomes a direct negotiating point against your asking price.

Customer concentration. A buyer financing an acquisition through an SBA loan needs to demonstrate stable, diversified cash flow to their lender. If one commercial client represents 25% of revenue, expect that to trigger scrutiny or escrow requirements.

Transferability of relationships. If customers call the owner's personal cell phone and expect the owner on-site, that's a risk. If customers call the main line and work with whoever is dispatched, that's transferable.

Frequently Asked Questions

How is a plumbing company different from other trades businesses when it comes to valuation? Plumbing companies tend to command slightly higher multiples than some other trades because of the licensing barrier to entry, which limits buyer competition and supports margins. Electrical and HVAC businesses are comparable. However, the same fundamentals apply: recurring revenue, technician depth, and owner independence drive value in all trades.

Does the size of my plumbing company affect the multiple I'll receive? Yes, meaningfully. Businesses with under $200K in SDE typically trade at the lower end of the range—buyers discount for size risk. Once EBITDA crosses $500K, you begin attracting private equity interest, which tends to push multiples higher. The median plumbing business on the market today sits in a range where individual buyers and search funds are the most active acquirers.

I own my vehicles and equipment outright. Does that increase my valuation? It depends on how the deal is structured. In most transactions, vehicles and equipment are included in the sale and their value is already reflected in the business's earnings capacity. Owned real estate, on the other hand, is typically valued and transacted separately. Talk to your advisor about how to structure the asset component of your deal.

How long does it take to sell a plumbing company? Most plumbing business sales close within 6 to 12 months from the time of listing. The timeline depends on asking price accuracy, the quality of your financial documentation, and how quickly buyers can complete SBA financing, which is the most common deal structure in this size range. Overpriced listings often sit for 12+ months before repricing.
