Plumbing companies are bought for repeatable revenue and a crew that stays. Service and repair work, with its recurring customer base and better margins, prices differently from new construction contracting, and a company doing both should present them separately.

Service against construction
Service and repair produce many small jobs at higher margin with a customer base that comes back. New construction produces fewer, larger jobs tied to builders and the housing cycle. Buyers price the first higher because it is more durable, and a company that reports one revenue line hides its own best argument.
The license and the crew
Where the master license the business trades under is personal to you, the buyer needs a plan for that from day one, either their own licensed person or a commitment from you. Technician retention is the other constraint: in a trade short of labor, the crew is much of what is being bought and turnover is a visible discount.
What preparation moves the number
Converting one off customers into maintenance agreements, taking yourself out of estimating and selling, and clean job costing so a buyer can see margin by job type. Each takes months, and each changes the multiple rather than just the earnings, which is why they are worth more than a hard negotiation at the end.
Questions people ask about sell plumbing business
Who buys plumbing companies?
Local competitors, regional trades platforms backed by funds, and individual buyers with lending. The platforms usually pay more and ask for more in diligence and transition.
Does my truck fleet add value?
It is priced on condition and remaining life rather than book value, and it is checked to see whether the earnings require immediate replacement spending.
Will I have to stay on?
Usually for a transition, longer if the license or the customer relationships are personal to you.
