What Is My Plumbing Business Worth in 2026?

Plumbing businesses in 2026 sell for 2.0x–4.0x SDE for owner-operated shops, and 3.0x–6.0x EBITDA for businesses generating over $1M in earnings. A shop doing $1.2M in annual revenue with $300K in seller's discretionary earnings will typically fetch $600K–$900K at market. Businesses above that threshold attract PE roll-up buyers—Neighborly (Mr. Rooter), Wrench Group, Champions Group Holdings—and multiples step up noticeably when that caliber of buyer is at the table.

This guide is for plumbing business owners generating $500K–$10M in annual revenue who are considering a sale in the next one to five years. Whether you're ready to go to market now or still in the planning stage, understanding how buyers value your business—and what moves the number—is the most consequential financial decision you'll make.

How are plumbing businesses valued?

Plumbing businesses are most commonly valued using a multiple of Seller's Discretionary Earnings (SDE) or EBITDA. SDE is the standard method for businesses under $2M in revenue—it adds back owner compensation, personal expenses run through the business, and one-time costs to show the full earning power available to a new owner. EBITDA is preferred for larger operations where professional management is already in place and the owner isn't doing service calls.

For a plumbing business doing $1.2M in revenue at 25% margins, SDE might come in around $300K, yielding a sale price of $600K–$900K at a 2.0x–3.0x multiple. Revenue multiples (0.34x–0.66x gross revenue) are sometimes used as a sanity check but rarely drive the final price. What matters is the quality of your earnings: how recurring the work is, how dependent the business is on you personally, and whether your three-year financials can survive due diligence without surprises.

What are current plumbing business multiples in 2026?

In 2026, plumbing businesses are trading at 2.0x–4.0x SDE in most lower middle market transactions. Businesses with recurring service revenue, licensed management in place, and $500K+ in SDE trend toward the upper end. EBITDA multiples range from 3.0x–6.0x depending on scale, with larger businesses attracting premium offers from PE-backed buyers who have capital to deploy and timelines to hit.

The private equity consolidation wave that accelerated after 2022 has maintained competitive buyer pools for quality operators—PE firms have acquired nearly 800 HVAC, plumbing, and electrical companies since 2022. That said, multiples are more disciplined today than at the 2021–2022 peak. Businesses with heavy owner dependence, single-customer concentration, or deferred equipment maintenance still see compressed multiples regardless of market conditions. A clean shop with a service agreement book, licensed foreman, and three reconciled tax returns exits near the top of the range. A truck-and-tools operation where the owner is the business exits near the bottom.

Who is buying plumbing businesses right now?

The most active acquirers in 2026 are private equity-backed consolidators building regional and national home services platforms. Neighborly—whose brands include Mr. Rooter Plumbing—remains one of the most consistent buyers of residential plumbing businesses in the Southeast. Wrench Group, backed by Leonard Green & Partners, Oak Hill Capital Partners, and TSG Consumer Partners, operates across the region and continues adding licensed plumbing operators. Champions Group Holdings acquired Bee's Plumbing in 2026, demonstrating active appetite for established residential operations. Eagle Merchant Partners has been active across the Southeast partnering with home services operators.

Beyond the major consolidators, there is a robust market of individual owner-operators using SBA 7(a) financing to acquire their first or next business—typically targeting operations in the $500K–$2M revenue range with a willing seller who provides a 60–90 day transition. Strategic acquirers—HVAC or electrical contractors adding plumbing capability—represent an underutilized buyer channel that can produce competitive offers, particularly in metro markets where bundled home services create margin advantages.

What makes a plumbing business worth more?

Recurring service agreement revenue is the single biggest value driver. A plumbing business with signed maintenance agreements generating $10K–$20K per month in predictable income gets valued differently than one that depends entirely on break-fix call-ins. Buyers and their lenders love predictable cash flow—it reduces risk and supports higher leverage in deal financing.

Management depth is the second critical factor. When I can show a buyer that the business has a licensed foreman or service manager who knows the routes, the clients, and the suppliers—and plans to stay—deal certainty improves and multiple compression decreases. Commercially-licensed technicians and the ability to bid municipal or commercial maintenance contracts adds scale potential that residential-only shops don't have. Fleet condition, software platforms (ServiceTitan or Housecall Pro), and low technician turnover all factor into due diligence. Clean three-year financials—organized books, documented add-backs, and consistent revenue recognition—can be worth 0.5x–1.0x in multiple difference at the closing table.

What Hurts Plumbing Business Valuations?

Owner dependency is the most common value killer. When the owner holds the master plumbing license, runs service calls personally, and is the primary contact for major clients, buyers see transition risk—not a business asset. Lenders see it too, which affects financing availability and therefore the pool of qualified buyers. Customer concentration is the second most common issue: if more than 25–30% of revenue comes from a single commercial client or property management company, buyers discount for the risk of losing that relationship post-sale.

Deferred fleet maintenance, aging equipment without replacement plans, and informal subcontractor arrangements that don't survive IRS scrutiny all reduce net value. Mismatched financials—where tax returns look materially different from your QuickBooks P&L—are an immediate red flag that adds months to due diligence or kills deals entirely. These problems are fixable, but they require time. Sellers who discover them during due diligence have no leverage to fix them.

How Long Does It Take to Sell a Plumbing Business?

Most plumbing business sales take 6–12 months from first engagement to closing. Well-prepared businesses with organized financials and a licensed team in place can move through in 6–9 months. Transactions using SBA financing, which requires bank processing and lender approval, often run closer to 10–12 months. The most controllable variable is preparation: sellers who come to market with three clean tax returns, a clear add-back schedule, and documented service agreements close faster and for more money than those who start from scratch after engaging a broker.

"I worked with a plumbing owner a couple years back—great guy, 22 years in the business, $1.8M in revenue, personally doing service calls three days a week. His EBITDA looked fine on paper, but every PE buyer asked the same question: what happens when he stops showing up? We spent six months helping him promote his lead tech to service manager and build a documented service agreement book. When we went back to market, we got three competitive offers and closed at 3.8x SDE—nearly a million dollars more than his initial estimate. The work before the sale is where the money is made." — John M. Salony
