How to sell a plumbing business
A plumbing sale runs on the same timeline as most home-services exits: about six to twelve months start to finish, with financial preparation and buyer conversations taking the bulk of it, and roughly four to six months from a signed letter of intent to a funded close. The single best thing you can do to compress that is to hand a buyer clean, normalized financials and operations that don't live in your head.
Buyer type sets the multiple. An individual operator or self-funded searcher typically pays 2.0-4.0x SDE and often uses SBA financing. A search fund generally pays around 3-5x EBITDA, while a private-equity roll-up pays about 3.5-6.5x EBITDA and usually structures 60-80% as cash at close, with the rest as an equity rollover, seller note, or earnout. A strategic buyer already running trades in your region can reach toward 5-10x EBITDA when your route density or commercial relationships expand their footprint.
In plumbing, value concentrates in the work that repeats. Service and repair revenue, drain and sewer maintenance, and standing commercial accounts are worth more than thin-margin new-construction rough-in. Buyers also reward depth of bench: master-plumber licenses tied to the company rather than just the owner, tenured techs, documented pricing and dispatch, a maintained truck fleet, strong online reviews, and a steady flow of inbound leads. Each of those reduces a buyer's risk and nudges you up within the 3.5-6.5x EBITDA band.
Think about after-tax proceeds early. Most of your gain is taxed at long-term capital-gains rates of about 15-20% federal, plus the 3.8% net investment income tax for higher earners (generally not owed by owners who materially participate) and state tax, and asset deals typically tax the seller less favorably than stock deals. DealSeam represents the buyer-paid side of these transactions: we connect owners with vetted acquirers where there's a real fit, and sellers pay nothing. We can't and won't guarantee a sale or a price, but we can show you what your business is worth and who is searching.
Related questions
What drives a plumbing company's multiple the most?
The mix of recurring service-and-repair work versus one-time new construction. Predictable, repeat revenue and standing commercial accounts justify a higher multiple than project-based install work.
Does my license transfer to the buyer?
It depends on your state and how the deal is structured. Buyers strongly prefer a master plumber and qualifying license that can stay with the business, or licensed staff who remain, so the company keeps operating legally after you leave.
How much cash will I get at closing?
In a private-equity deal, expect roughly 60-80% of the price in cash at close, with the remainder as an equity rollover, seller note, or earnout. An all-cash individual buyer may pay closer to full price but at a lower 2.0-4.0x SDE multiple.
How long will the whole process take?
Plan on six to twelve months overall, with about four to six months between the letter of intent and closing once a buyer is committed.
What does it cost me to work with DealSeam?
Sellers pay nothing. DealSeam is paid by buyers on closed deals, unlike a traditional broker that typically charges the seller an 8-12% commission.
