Based on hundreds of real buyer-seller diligence conversations we’ve helped happen on Rejigg. These are the plumbing-specific topics that move price, slow lending, or kill deals outright: licenses, dispatch, callbacks, fleet, and the routines that protect margin when the schedule gets slammed.
Each topic below comes from real buyer-seller conversations. Here's what they ask, what they're really evaluating, and how to prepare.
Licensing
They need to know you can keep pulling permits and passing inspections without you. A plumbing shop can look profitable and still be hard to buy if the qualifying license sits with the owner and there’s no written bridge. Buyers also pay attention to your permit habits because sloppy permitting tends to turn into claims, refunds, and bad reviews later.
How to prepare
Great Answer
We operate in three jurisdictions, and here are the qualifiers and renewal dates for each. I’m the qualifier in City A, and I’ll stay on for six months post-close to qualify permits and handle inspection issues while our service manager completes the remaining requirements to qualify. We pull permits on all permitted work, and we track permit status and inspections in a simple log so jobs do not stall.
Okay
Licenses are covered, and I’m open to staying on for a short period if my license is needed. We pull permits when required and inspections usually go fine.
Gives Pause
The license is in my name, but it should be fine. We usually skip permits unless a customer pushes for it.

Financials
Buyers want profit they can trust and repeat after the owner steps back. Plumbing books get muddy fast with truck expenses, owner payroll, ’run it through the business’ spending, and rework that never gets coded as warranty. If the story does not tie to deposits and job totals, lenders drag their feet and buyers get conservative.
How to prepare
Great Answer
We tie the monthly P&L to the field service system totals, and bank deposits reconcile. Owner add-backs are documented line by line, mostly personal vehicle costs and a couple one-time equipment purchases. We also track warranty and callback labor so you can see gross margin after rework, not just invoiced revenue.
Okay
The books are accurate, and we can explain the big expense lines. Warranty costs are not perfectly separated today, but we can pull the detail.
Gives Pause
The accountant handles it and it’s basically right. A lot of personal stuff runs through the business, but everyone does that.

Owner Dependence
They’re pricing how much revenue and problem-solving is still tied to you personally. In plumbing, owners often become the closer for big estimates, the person who smooths over angry customers, and the keeper of all the one-off pricing and permit knowledge. If that dependence is real, buyers assume more churn and more disruption right after close.
How to prepare
Great Answer
Most customers do not need me anymore. The service manager handles pricing exceptions and escalations up to a set dollar amount, and our office lead owns scheduling problems and review responses. I still handle a few commercial relationships and the largest install estimates, and we have a 90-day handoff plan with joint calls and a shared inbox.
Okay
Some people ask for me, but the team handles most issues. I can stay on for a transition period.
Gives Pause
Big estimates and most problems come to me. Customers trust me, so I’d need to stay involved.
How Rejigg helps: Rejigg supports direct messaging and scheduled buyer calls so you can run a clean transition plan with the real operators in the room, not a telephone game through a broker. Learn more in the guide
Dispatch
Buyers are underwriting whether calls turn into booked jobs and whether your board stays efficient when things go sideways. In service plumbing, margin leaks when the phone goes unanswered, triage changes by who picks up, or techs burn half the day driving. A tight dispatch process usually shows up as steady close rates and less overtime chaos.
How to prepare
Great Answer
We average about 45 inbound calls per day and book around 70% when we’re fully staffed. After-hours goes to an answering service that uses our triage script, and emergencies route to the on-call tech on a clear rotation. We mainly work these zip codes, we charge a zone-based trip fee outside the core area, and we review jobs per tech per day and drive time monthly.
Okay
Dispatch runs smoothly most days, and we stay booked. We have after-hours coverage for emergencies.
Gives Pause
Dispatch is mostly one person, and we wing it each morning. When it's busy, we just work late.
How Rejigg helps: Rejigg makes it easy to share dispatch and call-handling proof (reports, recordings, policies) in one controlled place inside the data room. Learn more in the guide
Quality Control
Callbacks quietly burn profit through payroll, fuel, schedule disruption, refunds, and reviews. Buyers want a clear definition, a trend that matches your job volume, and proof you diagnose why it happens. When owners get vague here, buyers assume the margin is lower than the P&L suggests.
How to prepare
Great Answer
We define a callback as a return trip within 30 days for the same issue. Over the last six months we’ve averaged 3.2% on service calls, and we tag each one by cause, like install error, parts failure, misdiagnosis, or customer misuse. When it spiked last quarter, we tightened photo documentation and added supervisor sign-off on certain water heater installs, and the rate came back down.
Okay
Callbacks are usually low, and we pay attention to them. We can pull recent return-visit data and categorize it.
Gives Pause
We do not track callbacks. Plumbing is plumbing and customers complain sometimes.
How Rejigg helps: Rejigg’s data room lets you share a simple callback log and warranty policy after NDA so buyers don’t assume the worst from a busy schedule. Learn more in the guide
Revenue Mix
They’re trying to see which jobs drive profit and which jobs create ’one bad week’ risk. Plumbing mixes can look similar on the surface, but the day-to-day reality changes a lot between drain cleaning, water heaters, sewer replacements, repipes, commercial service, and new construction. Buyers also want to know if big-ticket work comes from a repeatable estimating process or one standout tech.
How to prepare
Great Answer
Last year we were 55% residential service, 15% drain and jetting, 20% replacement installs like water heaters, and 10% sewer work. We can show gross margin by bucket and the job size distribution so you can see how often we take on multi-day risk. Sewer and repipes work for us because we use a documented estimating and change-order process, and we can show it.
Okay
We’re mostly service and water heaters with some sewer work. We can estimate the mix and pull more detail from the system.
Gives Pause
We do everything. The mix changes all the time.

People & Bench
Buyers care less about total headcount and more about whether the key seats will stay: service manager, dispatcher lead, permit coordinator, and your best diagnostic tech. Losing one of those people right after close can wreck booking, increase callbacks, and spike refunds. They want to see you know where the business is fragile and you have a retention plan that’s written down.
How to prepare
Great Answer
Our dispatcher lead and service manager are the two key seats. Both have been here over five years, and their pay and schedule are built for stability. We also have two apprentices on a defined progression plan, and we reduce reliance on any one diagnostic superstar by standardizing training and job documentation.
Okay
We have a couple key people and I think they’ll stay. We’re working on building a deeper bench.
Gives Pause
If my dispatcher or top tech left, it would hurt. I’d just hire someone new.
How Rejigg helps: Rejigg’s deal flow tools help you keep the process confidential with vetted buyers and NDAs so key employees don’t get spooked by rumors. Learn more in the guide
Fleet & Stock
In plumbing, trucks and specialty gear set your real capacity and your customer experience. Buyers look for hidden capital needs, like aging vans, constant downtime, mismatched upfits, or truck stock that gets ’handled’ by last-minute supply house runs. If they expect to replace a chunk of the fleet soon, they bake that cost into price and terms.
How to prepare
Great Answer
We run 10 service vans with an average age of 4.5 years, and we can show year and mileage for each. Two are leased and eight are owned, and we follow a planned replacement schedule instead of waiting for breakdowns. Truck stock is standardized by role, restocks happen weekly, and large material purchases require office approval so job margins stay intact.
Okay
We have a fleet list and most trucks are in good shape. Inventory is managed, but it could be tighter.
Gives Pause
We have a bunch of trucks and they run fine. Techs restock when they tell us they’re out.
How Rejigg helps: Rejigg’s secure data room is built for sharing fleet lists, equipment schedules, and inventory policies without emailing sensitive files around. Learn more in the guide
Leads & Demand
Buyers want demand that’s trackable and not hanging on one platform or one marketing vendor. Plumbing shops that lean hard on Google Local Service Ads or paid search usually need to show what happens when spend changes or reviews dip. They also look at overflow handling, because ’the phone rang’ is not the same as ’we booked it profitably.’
How to prepare
Great Answer
Booked jobs are about 45% Google LSAs (Local Services Ads), 20% organic search, 15% referral, 10% property management, and 10% other. We track booking rate and average ticket by source, and we know what happens when LSAs slow because we’ve tested spend changes. When volume spikes, overflow goes to a trained call center with clear booking rules, and we prioritize emergencies and members without wrecking tomorrow’s schedule.
Okay
Most leads are Google and referrals. We can pull a breakdown and explain how we handle overflow.
Gives Pause
It’s mostly word of mouth and Google. We don’t track it closely, but the phone rings.

Our 6-step owner's guide covers everything from deciding to sell through post-sale transition.
What is a plumbing business typically worth?
Most plumbing businesses sell based on a multiple of owner earnings, but the multiple moves with plumbing-specific risk. License continuity, dispatch performance, callback control, fleet condition, and a real membership base tend to push value up. Install-heavy shops can be worth more when estimating and change orders are tight. Start with Rejigg’s free valuation calculator to get an estimate using real transaction multiples and documented owner add-backs.
Do I need a broker to sell my plumbing company?
No. You don’t need a broker to sell your plumbing company. Brokers usually charge 5–10% of the sale price for outreach and process work you can run yourself with the right tools. Rejigg is built for broker-free sales with vetted buyers, digital NDAs, a secure data room, and offer tracking, and it’s free for sellers. Use this walkthrough to map the process: prepare to sell your business.
How long does it take to sell a plumbing business?
Most plumbing sales take a few months from listing to closing, and longer when license continuity, permit history, or messy books slow down lender review. Speed usually comes down to how fast you can show proof on the big plumbing questions, like the qualifier plan, callback trend, dispatch metrics, fleet list, and lead mix. Rejigg keeps NDAs, messaging, and your data room in one place so you don’t lose weeks to email back-and-forth.
Can a buyer use an SBA loan to buy a plumbing business?
Often, yes. SBA 7(a) loans are common in the trades, including plumbing, when the financials are clean and the business can run without the seller acting as the dispatcher, estimator, and lead tech. Lenders still focus on license continuity, key employee stability, and whether cash flow covers the payment. You can model payments and down payment scenarios with Rejigg’s SBA loan calculator before negotiating terms.
What documents should I have ready to sell a plumbing company?
Have documents that answer plumbing diligence quickly: financial statements, tax returns, a fleet list, licenses by jurisdiction, insurance loss runs, membership details, and key supplier terms. Add operational proof buyers ask for, like a callback log, warranty policy, and dispatch or booking reports from your field service system. Rejigg’s built-in data room is designed for structured sharing. For a closing checklist, see due diligence and closing.
What are common add-backs for plumbing businesses?
Common add-backs in plumbing are owner expenses that won’t continue for a buyer, like personal vehicle costs run through the business, one-time legal or consulting fees, and non-recurring equipment purchases. Many shops also need to normalize owner pay if the owner is working as the on-call plumber or service manager. Documentation is the whole game. If you can’t show the invoice and explain why it goes away, buyers and lenders usually won’t credit it.
How does seller financing work in a plumbing business sale?
Seller financing means you take part of the price over time as monthly payments instead of all cash at closing. In plumbing, it often shows up when a buyer’s loan maxes out, or when the lender wants the seller to keep skin in the game. You get a potentially higher price, but you take repayment risk and wait longer to get paid. Rejigg’s offer comparison dashboard helps you weigh seller financing terms against price, timeline, and contingencies using deal negotiation guidance.
What is an earnout in a plumbing acquisition, and is it common?
An earnout is when part of the price is paid later only if the business hits agreed targets, usually revenue or profit. In plumbing, earnouts show up when the buyer thinks demand is tied to the seller’s relationships, a short-term marketing spike, or a backlog that might not hold. They can work when the targets are simple and reporting is clear. Rejigg helps you compare earnout terms across offers and keep definitions tight so disputes are less likely.
How should I think about working capital when selling a plumbing business?
Working capital is the cash tied up in day-to-day operations, mainly accounts receivable, inventory, and bills you haven’t paid yet. In plumbing it shows up in truck stock, parts room inventory, open commercial invoices, and deposits on installs. Buyers often expect a normal amount of working capital to stay in the business at closing so payroll and suppliers keep getting paid. Clean receivables and inventory records matter because vague numbers usually lead to conservative assumptions.
How do buyers value plumbing trucks and specialty equipment?
Most buyers treat trucks and equipment as part of the overall purchase, then adjust when they see near-term replacement needs. A clean fleet list with year, mileage, ownership status, and maintenance history prevents last-minute renegotiations. Specialty tools like jetters and cameras matter because they impact job speed and your ability to sell higher-ticket work. When a buyer expects immediate fleet spend, they often lower the price or push for more seller financing to cover it.
Should I sell my plumbing company as an asset sale or stock sale?
Most small plumbing deals are asset sales, where the buyer purchases assets and takes on only selected liabilities. Buyers tend to prefer that structure because it limits exposure to older claims, past permit issues, and tax problems. Sellers sometimes prefer a stock sale for tax or simplicity reasons, but many buyers won’t accept it without extra protections. Bring your CPA and attorney in early because the tax difference can be real.
What happens to my plumbing company’s licenses and permits after the sale?
Licenses and permits don’t automatically transfer just because the company sells. The buyer needs a qualifying license holder and a plan for each jurisdiction you operate in, plus a clean handoff for permits already in motion. Some deals use a temporary bridge where the seller stays employed to qualify permits for a defined period. Buyers ask early because it determines whether the business can keep working on day one without pausing jobs.
How do I keep my plumbing sale confidential from employees and competitors?
Confidentiality comes from controlling who sees details and when. Use NDAs, share information in stages, and avoid emailing sensitive files around. Rejigg is built for this. Buyers are pre-vetted, they sign NDAs digitally before seeing sensitive information, and you can control data room access by buyer and by folder. That lets you run a real process without broadcasting the sale to your market.
What non-compete terms are typical when selling a plumbing business?
Most buyers ask for a non-compete and non-solicit so the seller doesn’t open a new plumbing shop nearby or pull customers and technicians away. The exact terms vary by state, and enforcement varies too, so this is an attorney question in your local market. In plain English, the buyer is paying for your phone number reputation, customer relationships, and team stability. They want time to transition ownership without you re-entering the market.
How are plumbing memberships or service agreements treated in a sale?
Buyers value memberships when they are active, renewing, and supported operationally. They will look at churn, what’s included, billing method, and whether you can schedule the promised work without blowing up your calendar. If memberships are mostly discounts that create angry customers in peak season, they may not add much value. Bring a report showing active members, renewals, and revenue tied to members so it’s grounded in actual behavior.
What transition period do buyers expect when buying a plumbing company?
Most buyers want the seller involved for a defined period to transfer relationships, steady the team, and cover licensing or permit continuity when needed. In plumbing, that often means introductions to commercial contacts, a planned handoff for escalations and refunds, and mentoring the person who will own qualifier responsibilities. The cleanest transitions are role-based with a calendar and deliverables. Rejigg’s transition planning guide helps you structure it.
What are the biggest deal terms to watch in a plumbing business LOI?
In plumbing, LOIs often get tense around working capital targets, holdbacks tied to warranty risk, how commercial receivables are handled, and what happens if licensing takes longer than expected. You also want a clear list of what’s included with the fleet and specialty equipment. Look at the whole package, not just the headline price. Rejigg’s deal tracking and offer comparison helps you see terms side-by-side. Learn the basics here: negotiate a deal.
When is the best time of year to sell a plumbing business?
There’s no single perfect month, but timing changes how your numbers look and how much bandwidth your team has for diligence. Many owners aim to sell after a strong stretch so the last 12 months of earnings look solid, and before a period where on-call fatigue and weather-driven spikes make operations choppy. If you have a meaningful membership base, show renewal and scheduling patterns across the year so buyers don’t mistake seasonality for decline.
