Full Editorial Writeup
This is a 47-year-old plumbing, septic, and underground utility contractor operating in Florida, founded in 1979. The business serves residential, commercial, and light industrial customers across multiple divisions: residential and commercial plumbing, septic installation and repair, underground water and sewer line installation, and excavation and utility work. That diversification across service lines and customer types is the operational story here: when new construction slows, repair and septic service tends to pick up, which smooths revenue.
The company runs roughly $2.2M in reported annual revenue with approximately $500K in adjusted earnings, a healthy 23 percent margin for a trade services business of this size. The workforce is the real asset: five journeyman plumbers, a septic installer, two apprentices, and a master plumber who is also the owner. The owner being the master plumber is the central risk, because the license and the technical authority walk out the door at close unless the buyer or a new hire holds the required Florida credentials.
The seller is retiring and selling off-market through a broker, with seller financing available for qualified buyers. At a $2M ask on $500K cash flow, this prices at 4x, which is a full but defensible number for an established, licensed, recession-resistant trade with underground utility capability that is hard to replicate. The deal fits an experienced plumbing operator, a strategic buyer, or an established contractor looking to expand its footprint in Florida.
Why we like it
- Earnings quality is solid: roughly $500K adjusted earnings on $2.2M revenue is a 23 percent margin, strong for a trade services business, backed by a 47-year operating history and a staffed crew rather than a one-person show. The septic and underground utility lines carry higher barriers to entry than straight residential plumbing, which supports pricing and margin durability.
- The moat is regulatory and reputational. Licensed plumbing and septic work in Florida requires credentialed personnel, and this business has a master plumber plus five journeymen and two apprentices already in place. Nearly five decades of local relationships and repeat referral flow are expensive and slow for a new entrant to build.
- This is genuinely recession-resistant demand. Plumbing failures, sewer backups, and septic repairs are non-discretionary, and underground utility work ties to permitted infrastructure and new construction that has a long replacement cycle. Florida population growth adds a structural tailwind to both the service and installation sides.
- For the right operator there is real upside. The listing itself flags capacity expansion, more commercial accounts, and geographic broadening, and the business appears to run without formal sales or marketing. A buyer who adds service agreements and a dispatch system can lift both utilization and recurring revenue.
How to improve it
- Lock down the license risk first, then build margin. The owner is the master plumber, so within 90 days either confirm the buyer holds a Florida master plumber credential or promote and retain a qualifying journeyman with a retention package. This is the single gating item on the entire deal.
- Launch a recurring septic and plumbing maintenance plan. Convert the existing septic and residential base into annual pump-out and inspection memberships billed on a schedule, which turns one-off jobs into predictable, higher-margin recurring revenue and raises enterprise value at resale.
- Install basic dispatch and job-costing software. A 47-year-old contractor almost certainly runs on paper or spreadsheets, so deploying field service management tools (ServiceTitan, Jobber, or similar) will tighten scheduling, cut windshield time, and expose which service lines and crews actually earn.
- Build a simple commercial sales motion. The listing shows no dedicated sales function, yet commercial and light industrial accounts offer bigger tickets and repeat work. Assign one person to pursue property managers, general contractors, and municipal utility bids to grow the diversified revenue base.
- Separate and scale the underground utility division. Water and sewer line installation and excavation are the hardest capabilities to replicate and often the highest-margin work. Track it as its own P&L, bid more permitted infrastructure jobs, and lean into Florida new-construction demand.
- Formalize apprentice-to-journeyman development. With two apprentices already on staff, a structured training and licensing pipeline reduces dependence on the open labor market and builds the bench needed to add crews without blowing up quality.
- Reprice and audit the job book. After nearly five decades, legacy pricing and long-standing customer relationships often mean under-market rates. Review material markups, labor rates, and emergency call pricing to capture margin the owner may have left on the table out of loyalty.
Diligence notes
- Verify the master plumber license situation in detail. Confirm exactly which Florida license the business operates under, whether it is held personally by the retiring owner, and what the transition path is. If the license does not convey and no qualifying employee stays, the business cannot legally operate on day one.
- Scrutinize the earnings adjustments and revenue mix. The $500K is labeled adjusted cash flow, so request the add-back schedule and three years of tax returns to confirm the number is real and sustainable. Break revenue into residential, commercial, septic, and underground utility to understand concentration and the margin profile of each line.
- Assess customer and contract concentration. Underground utility and commercial work can hinge on a few large accounts or GC relationships. Pull a customer-level revenue breakdown and confirm whether work is recurring referral flow or dependent on a handful of relationships the owner personally controls.
- Inspect equipment, fleet, and the balance sheet. Excavation and underground utility work require trucks and heavy equipment, so confirm what is owned free and clear versus leased or financed, its age and condition, and any deferred capital expenditure. Also verify no material liabilities, liens, or warranty exposure transfer with the deal.
- Pressure test the 2026 growth projection. Management projects continued improvement, but confirm whether current backlog, signed contracts, and crew capacity actually support that forecast. Price the business on trailing actuals, not the seller's forward optimism.
- Validate the workforce retention plan. The value here is the licensed crew, so interview key journeymen about their intent to stay post-sale and review compensation versus local market. Build retention terms into the purchase agreement before closing.
