Plumbing Business
Running a plumbing business on your own means being the plumber, the dispatcher, the estimator, and the bookkeeper all at once.
This guide covers what to charge, whether you need a license, how to land your first clients, and which apps actually pay for themselves. It is written for the one-person operation, not a twenty-truck shop.
What kind of plumbing work?
Your pricing, licensing, and the tools you need all shift depending on the work you take. Most solo plumbers start in one or two of these lanes and expand later.
Residential service & repair
Leaks, clogs, fixture swaps, and water heaters for homeowners. The fastest lane to start: low equipment cost, steady demand, and quick same-day jobs.
New construction & remodel
Rough-in and finish plumbing for builders and remodelers. Higher ticket sizes, but you wait on other trades and live with longer payment cycles.
Drain & sewer
Snaking, hydro-jetting, and camera inspections. Strong margins and repeat work, but it needs specialised gear like a drain machine or jetter.
Commercial & contracts
Restaurants, offices, and property managers on recurring agreements. Predictable revenue, but expect Net-30 invoicing and stricter licensing.
Yes — you almost certainly need a license.
Unlike cleaning or pressure washing, plumbing is a licensed trade in nearly every U.S. state. Most require you to log apprenticeship hours, pass a journeyman exam, then a master or contractor exam before you can pull permits and run your own shop. Check your state board before you advertise — operating unlicensed can mean fines and voided work.
What to charge as a solo plumber
These are typical 2026 flat-rate ranges for a one-person operation in the U.S. Your local market, licensing tier, and overhead will move them. Always price to cover materials, drive time, and a real profit margin — not just your hourly cost.
Service call / diagnostic
$75–$200
Flat call-out fee, often credited toward the repair. Charge it every time.
Drain cleaning
$150–$400
Snake or auger a single line. Hydro-jetting a main runs higher.
Faucet / fixture swap
$150–$350
Labor only. Add parts and your materials markup on top.
Water heater install
$1,200–$2,500
Standard tank unit, supplied and installed. Tankless costs more.
Whole-home repipe
$4,000–$15,000
Depends on size, access, and pipe material (PEX vs copper).
Emergency / after-hours
$150–$450+
A premium over standard rates for nights, weekends, and holidays.

5 pricing mistakes that sink solo plumbers
The plumbers who struggle rarely lack skill — they undercharge. These are the five mistakes that quietly drain a one-person shop.
Not charging a service call fee
Driving out for free turns tire-kickers into unpaid appointments. Charge a call-out fee every time and credit it toward the work if they book.
Pricing by the hour, not the job
Hourly pricing punishes you for being fast and invites clock-watching. Flat-rate pricing protects your margin and ends the awkward conversation.
Underpricing emergencies
Nights, weekends, and holidays are your most valuable hours. If you do not charge a premium, you are subsidising other people’s emergencies.
Forgetting materials markup
Charging cost on parts leaves money on the table. A standard markup covers your sourcing time, pickup runs, and warranty risk.
Running everything on paper
Lost quotes, late invoices, and missed follow-ups cost more than any app. Even basic software pays for itself in one recovered job a month.
Plumbing business FAQs
The questions solo plumbers ask most before going out on their own.
Do I need a license to start a plumbing business?
In almost every U.S. state, yes. Plumbing is a regulated trade — most states require you to log apprenticeship hours, pass a journeyman exam, and then a master or contractor exam before you can pull permits and operate independently. Check your state licensing board before advertising.
How much does it cost to start a plumbing business?
A lean solo start-up typically runs $2,000–$10,000 once you already hold a license: a reliable van, hand and power tools, a drain machine, insurance, and basic software. Your vehicle and specialised gear like a jetter or camera are the biggest variables.
What should I charge as a solo plumber?
Most solo plumbers charge a $75–$200 service call plus flat rates per job rather than a straight hourly rate. Price to cover materials, drive time, overhead, and a real profit margin — not just your time. See the pricing ranges above for a starting point.
Is flat-rate or hourly pricing better?
Flat-rate wins for most solo operators. It rewards efficiency, protects your margin on quick fixes, and gives the customer a clear price up front. Hourly pricing caps your income at your speed and invites disputes over the bill.
What is the best software for a solo plumber?
Workiz is purpose-built for plumbing and our top pick; Jobber is the easiest all-rounder; Housecall Pro is strong on consumer-facing booking and payments. All three handle scheduling, quotes, invoicing, and card payments from your phone.
How do I get my first plumbing clients?
Start with a Google Business Profile, ask every customer for a review, and build relationships with local builders, property managers, and real-estate agents who need a reliable plumber on call. In the trades, referrals compound faster than ads.
How much do plumbers make?
A solo plumber’s take-home varies widely by region and specialty, but established one-person operations commonly net $70,000–$150,000+ after expenses. Emergency and commercial work tend to pay the most per hour.
Do I need insurance for a plumbing business?
Yes. General liability is essential and often required to pull permits or work for commercial clients. You will likely also want tools and equipment coverage, plus workers’ compensation if you hire. It is cheap relative to the risk of a water-damage claim.
Can I start a plumbing business without being a plumber?
Not legally in most states, because the work requires a license tied to an individual’s credentials. Some people partner with or employ a licensed master plumber to qualify the business — but you cannot pull permits or do the work yourself without the license.
