How to Start a Plumbing Business in 2026 (Costs, Licenses and First Customers)
By BRIX Editorial Team · Updated
To start a plumbing business, you usually need the license level your state or city requires to run a shop (often a master or contractor license), liability insurance at or above the board's minimum, and a stocked van. A licensed plumber with his own truck needs about $14,341 in our example.
Key takeaways
- Startup cash is about $14,341 for a licensed plumber using his own truck, or about $53,341 with a full kit (camera, jetter, press tool) and a used van (illustrative, calculator below).
- The BLS says most states and some localities license plumbers, usually after 2 to 5 years of experience and an exam.
- In Texas, a plumbing company works under a Responsible Master Plumber, who must carry at least $300,000 of commercial liability insurance and can serve only one company.
- Some places license plumbers locally: a New York City master plumber license takes 7 years of experience in the last 10 and two exams ($585 written, $530 practical).
- Insureon's plumbing customers pay about $147 a month for general liability, one of the highest rates among the trades.
How much does it cost to start a plumbing business?
Most plumbing shops start when a licensed plumber leaves an employer with his own hand tools and truck. In that case the cash goes to the gear an employer used to supply (a drain machine, a torch kit, test gauges), licensing, insurance and a reserve. Our example comes to $14,341. Add a sewer camera, a small jetter, a press tool and a used van, and it's about $53,341. Insurance (Insureon) and the service-call fee (Housecall Pro) are cited; everything else is illustrative.
- One-time costs
- $8,500
- Monthly fixed costs
- $1,947/mo
- Working-capital reserve (3 mo)
- $5,841
- Jobs a month to cover fixed costs
- 13
Plan on $14,341 before the first job pays: $8,500 to get set up and $5,841 to keep the lights on for 3 months. At $150 a job, about 13 jobs a month cover the fixed costs. Everything after that pays you and your supplies.

What license do you need to start a plumbing business?
Plumbing is one of the most tightly licensed trades. The BLS says most states and some localities require plumbers to be licensed, usually after 2 to 5 years of experience and an exam. The license that lets you work (journeyman) is often not the one that lets you run a company. Running a shop usually takes a master license, a contractor registration, or both, plus insurance. Who issues it differs: some states license statewide, and in others the city or county does.
| Where | Who licenses | What a shop owner needs | Official source |
|---|---|---|---|
| Texas | State Board of Plumbing Examiners (statewide) | A Master Plumber designated as Responsible Master Plumber (RMP) with at least $300,000 commercial liability insurance; $225 fee; one company per RMP; vans show the company name and RMP license number | TSBPE RMP |
| Texas (tiers) | TSBPE | Apprentice registration, then Tradesman-Limited, Journeyman, Master; 6 hours of continuing education to renew each year | TSBPE license types |
| Illinois | Department of Public Health (statewide) | Licensed plumber: 4 years as a licensed apprentice, an approved course and the state exam. Contractors register yearly with liability and workers' comp insurance | IDPH plumbing |
| New York City | NYC Department of Buildings (local) | Master plumber: 18+, 7 years of experience in the last 10, written exam ($585) and practical exam ($530); business needs general liability, workers' comp and disability insurance | NYC DOB |
| California | CSLB (C-36 plumbing contractor) | Four years of journey-level experience in the last ten, exams, and a $25,000 bond | CSLB |
Illinois shows how small the pool is: the IDPH licenses about 8,900 plumbers and 2,000 apprentices statewide. Apprentices there must be at least 16 and sponsored by a licensed plumber or an approved program. Wherever you are, the license on file is what lets you pull permits. No permit means no inspection, and that is where insurance claims on water damage get denied.
What insurance does a plumbing business need?
Plumbers pay more for liability than most trades, because one bad joint can flood a finished basement. Buy general liability at least at your board's minimum (Texas RMPs need $300,000), then add tools coverage, a commercial auto policy if the van is in the business's name, and workers' comp before your first apprentice.
| Coverage | Per month | Per year | When you need it |
|---|---|---|---|
| General liability | $147 | $1,768 | Before the first job; at or above your license minimum |
| Business owner's policy | $213 | $2,559 | If you have a shop or warehouse to insure too |
| Tools and equipment | $42 | $505 | As soon as the van carries your machines |
| Workers' compensation | $179 | $2,150 | When you hire |
| Commercial auto | $285 | $3,415 | Vans titled to the business |
| Professional liability | $67 | $808 | If you design systems or give written assessments |
| Commercial umbrella | $93 | $1,111 | When commercial customers ask for higher limits |
| Surety bond | $8 | $100 | Where your license or city requires one |
For structure, an LLC limits personal liability for business debts in most cases, while a sole proprietor is personally exposed; the SBA's business structure guide covers the trade-offs.

From journeyman to owner
The BLS puts the median plumber, pipefitter and steamfitter wage at $63,800 (May 2025), across 510,600 jobs, with 7% growth projected for 2025–35. Your shop has to pay you more than that after costs, or it's a harder job for the same money. Four things to sort out before you hand in notice:
- The license level. If your state requires a master license to run a company, find out how many hours and years you still need and get them documented now.
- Service vs. new construction. Service and repair pays faster and needs a phone that's answered. New construction pays slower and needs cash flow to float materials.
- Your non-compete. Read what you signed about soliciting your employer's customers.
- Your pricing. You've seen what the shop charges. Now work out what it costs you per hour to run the van. Our plumber career guide covers the license ladder.
What tools does a new plumbing business need?
Carry what finishes the common calls on the first visit: drains, toilets, faucets, water heaters and leaks.
- Drain gear. A drum machine for 1½–3 inch lines, hand augers and a closet auger. A sectional machine or jetter for main lines comes later.
- Joining. Torch and solder kit, PEX crimp or expansion tool, and a press tool once the volume pays for it.
- Cutting and threading. Pipe cutters, reciprocating saw, pipe wrenches; a threader if your area still has galvanized and black pipe.
- Testing. Pressure test gauges, a gas leak detector if you're licensed for gas, and a moisture meter for leak calls.
- Seeing. A sewer camera and locator turn a guess into a quote with video, and the inspection itself is billable.
- Truck stock. Wax rings, supply lines, flappers, fill valves, cartridges for the faucet brands in your area, fittings and a spare water heater if you can carry one.
Plumbing business launch checklist
Download the checklistDay 1
- Confirm the license level that lets you run a plumbing company in your state or city (often master or contractor)
- Register the business, get a free EIN, and file any contractor registration the state or city requires
- Buy general liability at or above your license minimum, plus tools coverage and any required bond
- Put the company name and license number on the van if your board requires it
- Open supply-house accounts for fittings, fixtures and water heaters
- Set your service call fee, after-hours dispatch fee and minimum charge
- Get a business phone line that rings through at night, because burst pipes don't wait for morning
- Learn the permit process for water heaters, sewer work and repipes in the cities you'll serve
Month 3
- Flat-price your top ten jobs (drains, toilets, faucets, water heaters) from real times
- Take before-and-after photos on every job for your Google profile and warranty records
- Track parts margin and stop absorbing supply-house runs
- Ask every customer for a review the same day
- Text back every missed call within minutes
- Book your continuing education hours if your license renews this year

- Add drain camera, jetting or water treatment work if your market pays for it
- Offer a yearly plumbing inspection or water heater flush to past customers
- Review your insurance limits against the size of jobs you now bid
- Pay quarterly estimated taxes on time
- Raise prices for the next year with notice to repeat customers
How should a new plumbing business price jobs?
Charge a service call fee, quote common jobs at a flat price before you start, and price emergencies as emergencies. Many plumbing customers call in a panic, and a clear flat price is what earns their trust. Time-and-materials still fits hidden leaks, slab work and old systems where you can't see the job.
| Service | Typical range | Pricing unit |
|---|---|---|
| Service call fee | $50–$250 | Per visit; travel and diagnosis |
| Labor | $75–$150 | Per hour, residential; up to $45–$200 by market |
| Emergency dispatch | $150–$400 | Per call; after-hours work at 1.5–3× standard rates |
| Drain clearing | $100–$275 | Per drain |
| Toilet repair | $100–$300 | Per toilet |
| Faucet or fixture install | $150–$600 | Per fixture |
| Water heater, tank | $900–$3,000 | Installed; tankless $1,400–$5,600 |
| Sewer line repair | $1,900–$3,700 | Per repair |
- Start from your real hourly cost. The contractor hourly rate calculator builds your rate from overhead and pay.
- Flat-price the water heater. The job pricing calculator has a 50-gallon gas water heater swap preset.
- Build the price book. Use the flat rate pricing calculator for drains, toilets and faucets.
- Don't confuse markup with margin. A 30% markup on parts is a 23% margin. See markup vs. margin.

How do you get plumbing customers when you're new?
Plumbing calls are urgent and local. The homeowner with water on the floor calls whoever answers first and can be there soonest. A new shop wins by being reachable, close and clear on price.
- 1
Claim your Google profile.
Set a tight service area, list emergency hours only if you'll answer them, and add van and job photos. See Google Business Profile.
- 2
Get referral partners.
Home inspectors, realtors, property managers and remodelers all need a plumber who returns calls. One property manager can fill a week.
- 3
Answer every call, day or night.
Use a plumbing call script so every caller gets the same questions. The missed call calculator shows what a missed emergency call costs.
- 4
Ask for the review on site.
Text a review link before you pull out of the driveway. Use our review request templates.
- 5
Follow up on big quotes.
Repipes, sewer lines and water heater upgrades often need a second touch. See estimate follow-up templates.
Paid lead sources and Google Local Services Ads can work for plumbing because the jobs are big, but track cost per booked job, not per lead. More channels are in how to get more plumbing customers.
Your launch tech stack
A one-van plumbing shop loses the most money in two places: emergency calls that go to voicemail, and parts that never make it onto the invoice. Before the first job, set up a business line that's covered at night, a calendar, a flat-rate price list on your phone, card payments on site and books that tie parts to jobs.
| Option | Fits when | Watch for |
|---|---|---|
| Cell phone, carbon-copy invoices, a spreadsheet | Your first few weeks | Night calls missed; parts forgotten on tickets; books done at tax time |
| Field service app (Housecall Pro, Jobber, ServiceTitan) | You want a price book, dispatch and invoices in one place | Someone still has to answer the phone. See Housecall Pro alternatives |
| BRIX | You want calls answered at 2 a.m. and books kept without a bookkeeper | Pricing isn't public yet; book a call to see if it fits |

Is a plumbing business profitable?
It can be, because licensing limits competition and emergencies support premium pricing. There's no trustworthy public figure for first-year owner income, so build your own: calls per week, average ticket, parts margin and how many big jobs (water heaters, sewer lines, repipes) you close each month, against the fixed costs above and the wage you're giving up.
