A plumbing contractor I know in Ohio ran his business for 22 years, netted $340,000 in his best year, and sold for barely 2.8x SDE — well below what a comparable shop with cleaner books would have fetched. Why? He was the business. Every commercial account called his cell phone directly, every apprentice reported to him personally, and his books commingled a company truck payment with three years of home renovation expenses. The buyer's lender flagged it, the price got chopped twice during due diligence, and the deal barely closed. Nothing about his trade skills was the problem. The problem was that nobody could buy the business without also buying him.
That's the story exit planning is meant to prevent. Most plumbing businesses sell for 3 to 5 times Seller's Discretionary Earnings (SDE). The spread between the bottom and top of that range is almost entirely explained by preparation — not luck, not market timing.
Plumbing businesses currently sit in an unusually favorable spot for sellers. Industry estimates put the US plumbing industry at well over $100 billion in annual revenue, and private equity-backed consolidators have been actively acquiring residential and commercial plumbing companies since roughly 2020. That demand is real, but it's selective. A well-run operation with documented systems, recurring revenue contracts, and low owner-dependency commands premium multiples. A shop where the owner still pulls every permit, manages every tech personally, and holds the key customer relationships in his own head gets discounted heavily — buyers aren't purchasing a business in that case, they're purchasing a job with extra steps.
There's also a demographic pressure building. Plumbing business owners skew older than the general small-business population, and a meaningful wave of boomer-owned trades businesses is expected to hit the market over the next several years. More sellers competing for buyer attention means owners who start planning now — rather than waiting until they're ready to retire — get ahead of that crowd instead of getting lost in it.
Before you can plan an exit, you need a credible figure to plan around. A serious buyer will cross-check your business against three methods.
Seller's Discretionary Earnings (SDE) multiple. SDE is net profit plus your salary, benefits, one-time expenses, depreciation, and any personal costs run through the business. A business netting $180,000 with a $120,000 owner salary has roughly $300,000 in SDE. At a 3.5x multiple — realistic for a single-location residential plumbing company doing $1.5M–$3M in revenue — that's a $1.05 million valuation.
What moves the multiple:
EBITDA multiple. Once a plumbing business clears roughly $500,000 in EBITDA, strategic buyers and private equity groups tend to shift valuation methods entirely, with multiples for well-run trades businesses carrying commercial contracts often landing in the 5x–8x range, according to deal data tracked by trades-focused M&A brokerages.
Asset-based valuation. Less relevant for an ongoing operation, but it matters if you own real estate, a sizable fleet, or specialized equipment. Four owned service vans at $25,000–$40,000 each plus $80,000 in tools and inventory is tangible value a buyer will recognize even when cash flow is thin.
Practical move: hire a Certified Business Valuator or a trades-focused broker for a formal valuation 24 to 36 months before your target exit. Expect to pay $3,000–$8,000. That fee routinely pays for itself the first time a buyer tries to lowball you, because you'll have a defensible number instead of a guess.
This is the most emotionally loaded decision in trades succession, and the honest answer is that it depends on what you're actually optimizing for: price, legacy, or certainty.
Selling to an employee or management team (an MBO) typically nets a lower headline price but carries real advantages — your operations manager already knows the customers, the transition risk to the brand is low, and SBA 7(a) loans are commonly used to finance these deals for established trades businesses. The catch: most employees can't fund a full buyout upfront. You'll likely carry a seller note for 20%–40% of the purchase price, which means you're exposed if the new owner stumbles operationally. You've effectively become their bank, and banks don't get to walk away when a borrower struggles.
Selling to a third party — a strategic acquirer (another plumbing company) or a PE-backed platform — generally pays the highest price and the most cash at closing. The trade-off is a harder due diligence process, a longer timeline (6 to 12 months from first conversation to close is typical), and less certainty about what happens to your team afterward. PE-backed consolidators have become a legitimate exit route for plumbing companies above $2M in revenue, often willing to pay 4x–6x SDE for businesses that are professionally run with documented systems.
The hybrid path worth actually considering: sell a majority stake to a PE buyer while retaining 20%–30% equity, then exit fully in a "second bite of the apple" transaction 3 to 5 years later when the consolidated platform sells. This isn't a footnote — owners who take this route sometimes double their total exit proceeds compared to a single full sale today. The trade-off is that you're still tied to the business's performance and to a new corporate parent's decisions for years, which isn't the clean break everyone imagines when they picture "selling the company."
Build a recurring revenue base. A residential plumbing company with a $300-per-year maintenance club and 400 active members has $120,000 in revenue locked in before a single service call. Buyers pay a premium for that over equivalent one-time revenue because it signals loyalty and lowers post-acquisition risk. If you don't have a program like this, start now — it typically takes 18 months to build meaningful membership volume, so this isn't a lever you can pull the year you decide to sell.
Document your systems and reduce owner dependency. Buyers are paying for a business, not an operator. Every process you write down — dispatching, quoting, parts ordering, tech onboarding — removes a line item from their due diligence checklist. Centralizing job history, customer records, and revenue reporting in a platform like Jobber or ServiceTitan makes the operation something a new owner can actually step into.
Clean up your books three years in advance. Buyers and their lenders want three years of reviewed financials. That means separating personal and business expenses now, documenting any cash transactions, and working with a CPA on accurate P&Ls and balance sheets. This is the single most common reason deals stall or reprice mid-diligence — not fraud, just messy bookkeeping that makes a buyer nervous about what else might be undocumented.
A workable plan needs three years of runway at minimum — less than that and you simply can't fix the things that move a valuation.
| Stage | Timeline | Key actions |
|---|---|---|
| 1. Baseline assessment | Year 1, Q1 | Formal valuation; identify the gap between current and target value |
| 2. Value-building | Year 1–2 | Systemize operations; grow recurring revenue; reduce owner dependency |
| 3. Financial cleanup | Year 2, Q3–Q4 | Three years of clean, reviewed financials; normalize add-backs |
| 4. Exit structure decision | Year 3, Q1 | Choose buyer type and deal structure (asset sale, stock sale, earnout) |
| 5. Go to market | Year 3, Q2–Q4 | Engage broker or advisor; manage due diligence; close |
Asset sale vs. stock sale. Most small business deals are structured as asset sales — better for the buyer (stepped-up depreciation), generally worse for the seller (ordinary income rates on certain asset classes). How goodwill, equipment, and customer lists get allocated in the purchase agreement can shift thousands of dollars in your favor or against it, and this is negotiated, not fixed.
Installment sale treatment. If you carry a seller note, you may be able to spread capital gains recognition over the years you actually receive payments, rather than recognizing the full gain in year one. On a $1.2 million deal, that timing difference can be the difference between two tax brackets.
Qualified Small Business Stock (QSBS). If your company is a C-corp meeting IRS Section 1202 criteria, you may be able to exclude up to $10 million in capital gains from federal tax. Most trades businesses are S-corps or LLCs, but converting several years ahead of a sale is worth modeling with a CPA — this only works if you plan for it early, not the year you decide to sell.
Charitable Remainder Trust. If philanthropy is part of your goals, a CRT lets you transfer business interest into a trust before the sale, defer immediate capital gains tax, draw income for life, and ultimately benefit a cause you choose.
None of this should be evaluated without a CPA who has actually handled trades business exits. The fee is trivial next to the tax exposure on a seven-figure sale.
A price everyone agrees on doesn't guarantee a closed deal. Three things protect you during the gap between signing and closing:
How long does it actually take to sell a plumbing business?
Most sales run 9 to 18 months from decision to cash in hand: 2–4 months to prepare financials and marketing materials, 3–6 months to find and vet buyers, and 60–90 days to close once a letter of intent is signed. Internal sales to employees often take longer because of financing logistics.
What's a realistic price for a $2 million revenue plumbing business?
At 15% net margins ($300,000 profit) plus a $100,000 owner salary, SDE lands around $400,000. At 3.5x–4.5x, that's a $1.4M–$1.8M valuation range. Recurring revenue, clean books, and reduced owner dependency push you toward the top of that band — and the gap between top and bottom on a deal this size is real money, not rounding error.
Do I need a broker?
Not legally, but the math usually favors one above $500,000 in sale price. Trades-focused brokers typically charge 8%–12% commission, but they run a competitive process that a solo seller negotiating with the first interested buyer almost never replicates.
What happens to my employees when I sell?
Depends on the buyer. Strategic acquirers (other plumbing companies) usually retain field staff because they need the licenses and the labor. PE-backed roll-ups tend to standardize back-office operations, which can mean real changes for admin and dispatch staff even when field crews stay untouched. You can negotiate protections into the agreement, but you can't guarantee outcomes — be as transparent with your people as the process legally allows.
Can I sell if I still have an SBA loan outstanding?
Yes, but the loan has to be paid off at or before closing — it doesn't transfer to a new owner without SBA approval, which is rarely granted. Your broker or attorney will build the payoff into the deal structure; if the balance is large relative to sale price, it affects your net proceeds directly.
Starting too late. Owners who begin planning 12 months or less before they want out almost always leave money behind — either because three years of financials can't be cleaned up on that timeline, or because the recurring revenue and systems buyers pay premiums for simply can't be built that fast. Sellers rarely regret selling. They regret not starting two or three years earlier than they did.
One thing to do today: pull your last three years of P&Ls and calculate your SDE. If you don't know the number, you can't plan toward it — and that one calculation, done with your bookkeeper in about 90 minutes, is the actual foundation of everything above.
