Service and repair against new construction, the license on the wall, and the plumbers who show up when a pipe lets go. How a buyer reads a plumbing and heating company, and what to settle before one does.
Capstone reports plumbing inside one combined segment with HVAC and electrical, so the deal figures below cover all three trades. Demand for a well-run plumbing company is broad, and the buyers arriving with it know exactly which records they want to read.

Left unanswered, each one becomes a reason to lower the offer. Answered with records, each one supports it.
Who calls you decides how steady the revenue looks.
A plumbing company fed by homeowners and property managers calling for repairs reads as durable demand that does not wait on a housing start. Rough-in and finish work for a handful of builders reads as cyclical, and if one builder slows, so does the company. Most owners run both. The buyer wants to see the split, and how much each side actually earns after labor and materials.
The repeat work is where the recurring value sits.
Drain cleaning, camera inspections, sewer line repair and water heater replacement bring the same households back again and again, and they are priced in the field rather than bid. Service agreements and annual boiler or water heater maintenance plans add a layer the buyer can count. The question is whether those customers can be traced from first call to fifth.
The right to pull a permit has to outlast the sale.
Most states and many localities license plumbers, and many require a master plumber to hold or qualify the company license. When that license is yours alone, the buyer is underwriting your continued presence, and will structure the deal to keep you. A second licensed master on staff, or a clear path to one, changes that conversation.
A buyer prices the cost of keeping the trucks staffed.
Most plumbers learn the trade through an apprenticeship of four or five years, so a bench cannot be rebuilt quickly after it walks out the door. Buyers look at how many licensed journeymen and masters you carry, how long they have stayed, how they are paid, and whether you are growing your own apprentices. A company that trains its next generation in-house earns credit for it.
Systems show the buyer the company can run without you on the phone.
Flat-rate pricing from a maintained price book, dispatch run by someone other than the owner, and call data that shows close rates and average tickets all tell a buyer the business is a system rather than a person. Commercial service work for property managers, restaurants, schools and facilities adds contracted revenue, provided no single account carries too much of it. Callbacks and warranty work belong in the same file, because a buyer will ask what they cost.
A founder doesn't have time to learn how a buyer thinks once the LOI is on the table. The negotiation happens at the speed of conversation. If they haven't already absorbed the buyer's reasoning, they can't respond to it in real time. They freeze or react. Both leave money on the table.
In plumbing, a buyer prices who takes the burst-pipe call at two in the morning.
The flooded basement, the restaurant with a backed-up line before the lunch rush, the property manager who only calls your cell. Each one shows a buyer how much of the company is still you, and each one can be moved onto the team before a sale.
Each one is fixable, and every one is cheaper to fix before a buyer finds it.
One buyer wants your service territory and repeat customers. Another wants your managers and your price book. Another wants to own the company for twenty years. The fit you choose shapes the price, the structure and what happens to your people.
Joins your plumbers, service agreements and zip codes to a multi-trade platform it already owns, often to add plumbing to an HVAC base, inside the borrowing limits its lender sets.
Makes your company the foundation of a regional plumbing and heating group. Needs a general manager, a licensed master who is not you, and a dispatch and pricing system that scales.
A larger privately held plumbing, mechanical or multi-trade operator nearby. Values your licensed plumbers, your commercial accounts and your density, and the overhead it can genuinely combine.
A listed services, distribution or water-technology company. Needs audited or audit-ready financials, controls it can report against, and a company large enough to matter to its results.
Holds for the long term and wants dependable cash flow and a team that stays. Often keeps the company name and your managers in place, and cares how the transaction is taxed.
An individual buyer who intends to run the company day to day. Bank and SBA financing set strict rules on earnings adjustments, and these buyers often want you alongside them through the first year.

Most of these steps take longer than an owner expects, which is why they start early. Done in advance, each one becomes evidence a buyer pays for.
Report service, replacement, drain and sewer, construction and commercial revenue separately. Begin qualifying a second master plumber so the company license no longer depends on you.
Put dispatch, quoting and key accounts with a service manager. Write retention plans for senior plumbers. Formalize the apprenticeship program and keep its records.
Document every add-back. Track callbacks and warranty cost. Tie service agreements to visits and renewals, so the numbers a buyer tests match the numbers you show.
Test the company against all six lanes, choose the one that fits your goals for price, people and your role, and prepare the documents that buyer reads first.
Owners hesitate to make this call for one reason: what happens if the team, a customer or a competitor finds out. So the rule is simple, and it holds from the first email.
You see the return, the entity structure and the estate plan. We see how a buyer will read the same company. A Value Protection Study gives your client a buyer's view of the business while there is still time to act on it, and keeps you at the center of the plan.
It falls in a range, and the buyer reading the company sets where in that range you land. Service and repair share, repeat drain and water heater customers, a license that does not depend on you, and the depth of your plumbing bench move it more than revenue alone. The Cordis MRI runs your own financials through each buyer lane and shows you that range.
Private equity add-ons and platforms, privately held plumbing and multi-trade operators, public companies, family offices, and search funds or independent sponsors. Capstone tracks plumbing together with HVAC and electrical. Of the 43 deals in that segment from January 1 to July 27, 2026, 27 were backed by private equity and 16 were made by strategic buyers.
Start with preparation, then a confidential process. Separate your revenue by line, document service agreements and add-backs, and secure the license and your senior plumbers. Then choose the buyer lane that fits your goals and approach a selected group of buyers under confidentiality agreements.
Steady service and repair demand, repeat drain, sewer and water heater customers, service agreements they can verify, a licensed bench that will stay, and pricing and dispatch that run without the owner. They also look for earnings that hold up once their accountants rebuild them from the job records.
Construction work is valued, and it is valued differently. Buyers treat it as more cyclical than service and repair, and they look closely at how much depends on a few builders. Reporting it separately, with margin and customer concentration, lets a buyer credit your service business on its own strength.
That depends on your state, the license structure, and whether the buyer acquires the company or its assets. In many states the company license is qualified by a master plumber, so the buyer needs a qualifier in place at closing. Planning for a second master well ahead of a sale keeps the license from becoming leverage against you.
Experienced plumbers are scarce, and every buyer knows it, so retention is priced into the offer. Written compensation plans, retention agreements for senior plumbers and a leader below you, put in place before a process starts, protect your team and your price together.
A marketed sale commonly takes six to nine months from launch to closing. The larger lever is the preparation before that: one to three years spent separating revenue lines, building the bench and the license succession, and evidencing earnings.
