How to sell a plumbing business
A plumbing company sells on the service book and on who holds the license, not on the trucks alone. Get the books and the license question straight before you pick a broker, a competitor, or a buyer.
The published average for this category is 2.61× owner earnings. See the full valuation guide. This is general information, not legal or tax advice.
Get the books ready
Separate service-and-repair revenue from new-construction and builder work, and keep maintenance-agreement revenue visible. A buyer will ask for tax returns, a current backlog, and job reports from whatever you use in the field. If those three do not agree, fix that before you share a number.
Calculate owner earnings
The usual plumbing add-backs are your salary, the truck and phone you use personally, depreciation on vans, interest, and a one-time cost such as a software change. Only add back what a buyer can see on a statement.
SDE explained: how to calculate owner earnings and add-backs walks through the method. Add back only what a buyer can verify.
Reduce owner dependence
If you are the only master plumber, the buyer is buying a job that stops when you leave. A second license holder, a service manager, and techs who already run calls make the sale about the company.
Licenses and permits
Plumbing contractor and master plumber licenses are usually issued to a person, not to the truck. In general the buyer needs their own license or a licensed person who will stay. This is not legal advice; ask your state licensing board what has to happen before closing.
Customer contracts
Maintenance agreements and builder contracts are worth more when they are in writing and can be assigned, or when the customer will sign a new agreement with the buyer. A handshake book of property managers is harder to transfer.
Timing
Collect a full year of returns and a clean backlog before you take meetings. Plan the closing around the license step, not the other way around. Employees and key customers should hear the news from you, on a timetable you and the buyer agree to.
Ways to sell
Through a broker
A broker who already sells plumbing and HVAC companies can run a quiet process and deal with lenders. You pay a commission, and you still have to produce the books.
Directly to a buyer
A local buyer or a consolidator who wants service work, not construction, may come to you directly. You handle diligence and the license timing yourself.
To an employee or a competitor
A service manager, a master plumber on staff, or a competitor who already overlaps your towns can be the simplest buyer, if they can get licensed and financed. Agree in writing what happens if the talks stop.

Questions
Do I have to use a broker?
No. A broker, a direct sale to a buyer, or a sale to an employee or competitor are all ordinary paths. Nobody contacts you unless you opt in.
Does the plumbing license transfer?
Usually the license is personal. Confirm the rule with your state board before you promise a buyer a closing date. This is not legal advice.
