Is a plumbing business worth starting — and what do customers pay?
If you hold the license, it's one of the surest trades to own: the water heater dies on a Sunday, the drain backs up before guests arrive, and the customer calls the first plumber who answers. The work splits into residential service and repair — leaks, clogs, fixtures, water heaters — paid the same day; drains and sewers, where the machine and the camera sell the next job; and new construction and commercial, bigger tickets paid 30 to 45 days later. This guide is about the business; if the license is the step you're on, how to become a plumber prints the apprentice, journeyman and master rungs state by state. HVAC is its own trade, with its own guide.
What customers pay. Fixr puts a plumber at $75 to $150 an hour, averaging $90, from $45 to $200 — an apprentice $20 to $40, a journeyman $45 to $90, a master $70 to $200 — with an initial service call of $50 to $300, an emergency rate around $150 an hour plus a $200 to $300 call-out, a toilet installed for $400 to $800, a water heater for $800 to $2,500 and a drain unclogged for $100 to $500 (Fixr, January 2025). Its water heater guide averages $1,400 installed, most between $900 and $3,000 for a gas tank, with labor $300 to $1,500 of that and the permit $25 to $1,500 (Fixr, January 2026); a main sewer line cleaning runs about $250, $200 to $600, from $150 for a snake to $1,000 for hydro-jetting a full blockage (Fixr, January 2025); a standard drain cleaning $150 to $300, with after-hours work at 1.5 to 2 times the rate (Fixr, October 2026). In Housecall Pro's pricing guide — written by a company that sells field-service software to plumbers — residential work is $75 to $150 an hour, the service-call fee $50 to $250, an emergency dispatch $150 to $400, a tank water heater $900 to $3,000 and a tankless $1,400 to $5,600, a drain clearing $100 to $275 (Housecall Pro, October 2026). Two companies' own pages: in Denver, Colorado First Plumbing charges a $95 diagnosis, $2,100 for a standard 50-gallon water heater installed, $295 to snake a main line and $175 for a sewer camera (Colorado First Plumbing's own prices); in Atlanta, TE Certified's guideline runs $99 to $540 for a drain cleaning, $295 to $795 to replace a toilet and $1,600 or more for a water heater (TE Certified's own price guideline, 2026).
The catch. The license comes years before the business, the van and the stock are real money before the first call, and contractor work pays late. As an employee, a plumber, pipefitter or steamfitter earned a 2025 median of $30.67 an hour, $63,800 a year, with growth much faster than average to 2035 (O*NET); a construction trades supervisor $38.42 an hour, $79,920 (O*NET). Insureon's averages for plumbing businesses are $147 a month for general liability and $285 for commercial auto (Insureon, August 2026). The owner's income has to beat $63,800 after the van, the insurance and the months contractors take to pay. That's what the rest of this guide sets up.
How to start a plumbing business, in plain English
Do you need a plumbing contractor license? In most of the US, yes — the company needs its own layer on top of the plumber's license. Your journeyman or master license lets you turn a wrench; the company needs a second layer — a contractor license, a registration or a master on record. Kentucky licenses the plumber and lets the company work under one: a company may engage in the business of plumbing "if a person connected with that company … in responsible charge of the plumbing work is a licensed master plumber" (KRS 318.110). Pennsylvania licenses neither — it "currently has no licensure or certification requirements for most construction contractors," and plumbing licenses are set by the municipalities that have them (Pennsylvania Department of Labor and Industry). The states we read:
- Texas. A company "that advertises or otherwise offers to perform or provide plumbing must secure the services of a responsible master plumber" (Texas Occupations Code §1301.351) — a master who lets one company work under his license. The designation is $225 to apply and $300 to renew, and needs "a minimum of $300,000 of commercial liability insurance coverage" (Texas State Board of Plumbing Examiners; §1301.552); the master license itself is a $25 processing fee, a $128.50 exam and $75 to issue (TSBPE). The master's license number goes on both sides of every van in two-inch letters, on every invoice and in every ad (22 TAC §367.10).
- California. The C-36 Plumbing Contractor license (CSLB) is needed once "the combined value of labor, materials, and all other costs on one or more contracts is $1,000 or more" (CSLB) — raised from $500 on January 1, 2025, and never covering work that needs a permit (CSLB bulletin 24-07). It takes "at least four full years of experience at a journey level" (CSLB), a $450 application and a $200 license fee for a sole owner (CSLB), and a $25,000 contractor's bond — plus a second $25,000 bond when the license is qualified by an employee rather than an owner with 10% or more (CSLB).
- Florida. A certified plumbing contractor is licensed statewide and a registered one locally; the application fee is capped at $150 ($350 with the exam) and the license fee at $250 (Florida Statutes §489.109), after four years of experience including a year as a foreman (§489.111), with $100,000 of public liability and $25,000 of property damage cover (Rule 61G4-15.003) and either a FICO score of 660 or a 14-hour financial responsibility course (Rule 61G4-15.006).
- New York. Licensing is by city. New York City's Licensed Master Plumber takes seven years of experience in the last ten, two of them as a registered journeyman, a $585 written and $530 practical exam, a $200 license and a $150 renewal (NYC Department of Buildings; NYC DOB); the licensee "must have at least 51% interest in the corporation" (NYC DOB, February 2026) and carry general liability of "a minimum of 1 million dollars" per occurrence (NYC DOB). On Long Island, the Village of Lynbrook registers plumbers for $200 for two years with a $2,000 bond for sewer work (Village of Lynbrook, 2025).
- Washington. A state plumbing contractor license: a $148.10 application, a $6,000 bond and $250,000 of liability cover, with a designated certified plumber who "could be an owner/partner or a full-time employee" (Washington L&I).
- Illinois. Every plumbing contractor registers with the Department of Public Health (IDPH) for $150 a year, with $100,000 of general liability, $300,000 bodily injury, $50,000 property damage and $500,000 of workers' compensation cover and a $20,000 bond (IDPH registration form).
- Kentucky. The company needs a licensed master plumber "in responsible charge of the plumbing work," who notifies the state when the connection starts or ends (KRS 318.110); no person, firm or corporation may do plumbing without general liability insurance "in an amount not less than two hundred fifty thousand dollars ($250,000)," proven to the state, with proof of workers' compensation and unemployment insurance, before the master license is issued or renewed (KRS 318.030).
- Pennsylvania. No state license (Pennsylvania DLI); for work on homes, the state's layer is the Attorney General's home improvement contractor registration — a $50 fee, with contractors whose home improvements totalled "less than $5,000 during the previous taxable year" excluded (Pennsylvania Act 132 of 2008). In Philadelphia, "Plumbing work needs to be done by a licensed master plumber": a year as a registered Philadelphia journeyman, the city's master plumber exam, $500,000 of general liability, $300,000 of auto liability and workers' comp — $303 to start and $253 a year (City of Philadelphia).
Whichever state you're in, check your state board and your city before you take the first paid job — a city can license on top of the state.
Can someone who isn't a plumber own the company? In Texas, the statute says the company "secures" a responsible master plumber and defines that plumber as one who lets a company use his license — nothing in it requires the owner to be the master, though no page says so in words; in California, the license can be qualified by a responsible managing employee working at least 32 hours a week, with the extra $25,000 bond (CSLB; CSLB); in Washington the designated plumber may be "an owner/partner or a full-time employee" (Washington L&I). New York City goes the other way: the licensee must own at least 51% (NYC DOB). Read your state's rule before you pick a partner.
The van, the stock and the tools. Housecall Pro's start guide puts the whole start at "$10,000 to over $50,000," with a work truck at $10,000 to $50,000, equipment at $5,000 to $15,000 and insurance at $1,000 to $4,000 (Housecall Pro, January 2026); Stripe's at $3,000 to $20,000 or more, with tools at $3,000 to $10,000 and a used vehicle around $25,000 (Stripe, August 2026). The dealers' own prices, seen October 2026: a RIDGID K-45 drain machine with cables and a tool set is $925.99 (Haus of Tools); a Milwaukee M18 press tool kit with six jaws $4,199 (Ohio Power Tool); a Milwaukee M12 PEX expansion kit $499 (Toolnut); a RIDGID 700 power threader $2,259.20 on sale (Wylaco); a Weather Guard four-shelf van unit $584 (Elite Truck); a new Mercedes-Benz Sprinter cargo van from $48,990 (Mercedes-Benz Vans, 2026). Most owners start in the vehicle they already drive: Scott Liess of Eco-Flow Plumbing in Santa Cruz — “I had a truck with tools and equipment. Then I just kind of slowly went on from there” (Lookout Santa Cruz, April 2023). Stock the van for the ten jobs you do most and open a supply-house account with delivery; our free plumbing estimate template and invoice template are the paperwork for before and after.
How to price: a service-call fee, then a flat price the customer approves. The guides above put the call at $50 to $300 (Fixr) or $50 to $250 (Housecall Pro), and the owners below price the job, not the hour. Build a price book for your twenty most common jobs, quote water heaters and repipes in writing, set an after-hours rate at 1.5 to 3 times standard — Housecall Pro's range — and check each flat price against the hours it really takes. Our guide to how much a plumber should charge goes deeper, and how plumbers get found on Google covers the phone ringing.
Permits and sales tax. Water heaters, repipes and sewer work need a permit almost everywhere, pulled by the licensed contractor: a water heater replacement permit is $40 in Butler County, Ohio (Butler County General Health District, 2026), $115 in Hubbardston, Massachusetts (Town of Hubbardston, September 2026) and $290 for a single-fixture residential permit in San Francisco (San Francisco DBI, July 2026); Fixr's national range is $25 to $1,500 (Fixr). Sales tax is state law: in Texas, "Labor to repair, remodel, or restore residential real property is not taxable," while "The total amount charged for remodeling, repairing, or restoring nonresidential real property is taxable" (Texas Comptroller, publication 94-116); in New York, installing a water heater is a capital improvement and not taxable, but "replacing a thermostat on a hot water heater" is a taxable repair — keep the customer's capital improvement certificate (New York Department of Taxation, TB-ST-104); in Florida, a lump-sum contractor "is the final consumer of materials and supplies" and collects no tax from the owner (Florida Department of Revenue, GT-800007); in Washington, a prime contractor collects retail sales tax "on the gross contract price" including labor (Washington Department of Revenue); in California, contractors are "consumers of materials they use and retailers of fixtures they install" (CDTFA). Ask an accountant before you print a price book.
How to register the business. In the US it's the same four steps in every state, with different fees. Form the business — an LLC is $40 in Kentucky (Kentucky SOS), $300 in Texas (Texas SOS) and $70 in California plus a $20 statement of information (California SOS), where every LLC also owes an $800 yearly tax (California FTB) — get the free EIN (IRS), open a business bank account, and get the city business license where your city wants one: Seattle's is $73 a year for a business with under $20,000 of revenue in the city and $147 from $20,000 to $499,999 in 2026 (City of Seattle). Our guide to whether you need an LLC walks through the choice.
Insurance and the bond. General liability is what the permit office, the property manager and the general contractor ask for, and in Texas, Florida, Illinois and New York City the license itself requires it. Insureon's averages for plumbing businesses are $147 a month ($1,768 a year) for general liability, $285 a month ($3,415 a year) for commercial auto, $179 a month ($2,150 a year) for workers' compensation, $213 a month for a business owner's policy, $42 a month for the tools in the van and $8 a month ($100 a year) for a surety bond (Insureon, August 2026); "Most states require a workers' comp policy for plumbing businesses with employees" (Insureon). NEXT says general liability costs most of its plumbing customers "$75 on average per month," from $55 to $328, and workers' comp a median of $209 (NEXT Insurance, October 2026). California requires workers' comp from the first employee (California DIR); Texas leaves it optional for most private employers (Texas Department of Insurance); OSHA lists "self-employed workers" among those the OSH Act doesn't cover (OSHA) — until your first apprentice.
Outside the US. In the UK, plumbing itself isn't a licensed profession — the government's register of regulated professions lists no plumber, only the registered gas engineer: "Registering with Gas Safe Register is a legal requirement for anyone carrying out gas work in the United Kingdom" (UK regulated professions register; HSE), and under the Water Fittings Regulations an installer must notify the water company before certain work unless they are an approved contractor (Water Supply (Water Fittings) Regulations 1999; WaterSafe). In Australia it is the opposite of the UK: New South Wales requires a license or certificate for any plumbing, draining or gasfitting work at all, with a contractor license needing a Certificate IV and two years' experience (NSW Government, July 2026) and costing $403 for a year, $803 for three or $1,235 for five including a $195 processing component in 2026–27 (NSW Government, September 2026); Victoria registers and licenses plumbers by class of work (ABLIS); the ABN is free (business.gov.au). Wherever you are, confirm the rules with your regulator and an accountant before the first paid call.
Franchise or independent? Mr. Rooter's own page puts the initial investment at $152,900 to $298,675, with $100,000 liquid and a 6% royalty (Neighborly, 2026); Benjamin Franklin Plumbing's a $43,000 start-up fee and a royalty of up to 6% or $1,500 a month (Benjamin Franklin Plumbing), with a directory putting its total at $143,273 to $286,702 and its franchisees' average territory revenue at $656,635 in 2025 (Franzy); Roto-Rooter's fee is $25,000 to $75,000 and its total $103,980 to $273,700 in a directory's reading of its 2024 disclosure (Franzy) — read the disclosure document before you sign anything. Every owner quoted in the next section built an independent shop.
The business, and the calendar. Answer every call, pull every permit, leave the kitchen cleaner than you found it, and land a property manager or two. For one licensed plumber going out alone, our free plumbing business plan puts the start at $6,316–$29,590: the contractor license and bond, a year of general liability — commercial auto at the high end — the drain machine and the big tools, van stock and shelving, registration, a city license, the website, software, and two months of running costs. The van itself and your own living costs come on top. The plumbing website templates show what a good plumber's site looks like, Zarla's plumbing website builder is how a homeowner searching for a plumber near them finds yours, and the best website builders for plumbers scores the alternatives.
What plumbing business owners actually say
None of this is our opinion about the trade. It comes from people who run plumbing companies, talking about the work in a trade magazine's profiles, a local news feature and a software company's interview between 2023 and 2026. Read each as theirs at the time; the dollar figures in older pages are that year's. Five things come up again and again.
The first year is cash flow, not profit. Constantin Geambasu of Water Rehab in Gilbert, Arizona: “My overhead went crazy — everything changed. I thought I would make more money, but it didn't work out like that. I didn't pay myself much for about a year — it was brutal” (Plumber Magazine, July 2025). Brent Hershey of Tri-County Water Services in Parkesburg, Pennsylvania: “We would squeak out a little profitability at the end of the year, but cash flow just got eaten alive through payroll. Every two weeks, that payroll hit” (Plumber Magazine, February 2026). Jeremy Sar, who started J.Sar Plumbing & Heating in Lowell, Massachusetts, in 2024: “Right now, I don't have a mortgage or any kids. There is no one depending on my success.” And: “Don't do it for the money and don't think it is going to be easier than working for someone else” (Plumber Magazine, July 2026).
“I found it pretty crazy that you can do a $300,000 job and not get the first payment for 30 to 45 days or more.” — Kevin Couper, Kyle Plumbing, Deerfield Beach, Florida, in Plumber Magazine, June 2024
Service pays every day; construction pays late. John Snyder of John Snyder Plumbing & Heating in Philadelphia: “When you're dealing with the big companies, you get lost...you make just as much doing residential work and you get paid every single day.” And on subcontracting: “I was financing those guys' jobs. Meanwhile for me, there was a lot of robbing Peter to pay Paul” (Plumber Magazine, September 2023). Brent McDonald of Rub-A-Dub Plumbing in Tyler, Texas, on new construction: “It was a little out of our wheelhouse. The margins are much lower and we are better at service.” And: “Our bread and butter is service plumbing” (Plumber Magazine, September 2026). Rodney Hardy of Standard Plumbing Contractor in Chicago: “The residential plumbing market is very profitable for us and we wouldn't want to lose that” (Plumber Magazine, September 2025). Tom Pecoraro Jr. of Velocity Plumbing & Heating in Quincy, Massachusetts: “One thing I enjoy the most, which I got hooked on early in my career, is getting paid when the job is done” (Plumber Magazine, January 2025).
Bigger isn't richer. Pecoraro: “We were growing too much and too fast. We had as many as six technicians, but were making less money” (Plumber Magazine, January 2025). Hershey, on why his company stopped bidding new construction in 2008: “I am not a new-construction plumber” (Plumber Magazine, February 2026). Snyder, on adding drain cleaning: “I realized how much money I was leaving on the table by not doing it” (Plumber Magazine, September 2023).
The first customers come from asking, and from the phone at 2 a.m. John Akhoian, who built Rooter Hero in California and Arizona, on his start: “I told them, ‘Hey, I'm a plumber, I'm just starting out. I'll do the first job for free. Give me a chance to earn your business.’” And: “after three or four months I got really busy. I had more work than I could handle” (ServiceTitan's podcast, April 2020). Jasen Hamilton of RoyalTee Plumbing in Kansas City: “I want to be your plumber. That means that if they need to call me at 2 a.m., they shouldn't hesitate to do so and I will go” (Plumber Magazine, July 2025). Pecoraro, on paid leads: “You pay for every job lead up front, but then I would give customers my name and contact information so they'd call me the next time they needed service” (Plumber Magazine, January 2025). Hardy: “When you do a good job, your name goes a long way” (Plumber Magazine, September 2025).
Start with the truck you have — and the license you've earned. Scott Liess of Eco-Flow Plumbing in Santa Cruz, who worked alone for five years: “It was hard. I drove all over the Bay Area getting work, but it was nice because I didn't have any overhead.” And: “In California, you have to work for somebody for four or five years and then you get your license” (Lookout Santa Cruz, April 2023). Bryan Landreth of North Alabama Plumbing in Huntsville, in a software company's interview: “I actually bought the van before achieving my license. And then my wife's like, ‘All right, it's time to buckle up, get the show on the road.’” And on why the trade holds up: “When the economy crashes, nobody's going to care about how their tile looks... but as soon as their toilet quits working, you're getting a call” (Swivl, October 2026). Geambasu, on how he wins the job: “I bundled all these things together for one price and people saw the difference” (Plumber Magazine, July 2025). Each of those is one owner's account of one company in one market, not a survey — read them as what the model can do, not what it does on average.
The through-line: the plumbing businesses that last get the contractor license and the bond before the first ad, start in service work that pays the same day, price the job and not the hour, keep payroll smaller than the calendar, and answer the phone when the water is on the floor.
THE STARTER KIT
What you need to start a plumbing business
The contractor license and the bond
Your plumber's license is the career; the business needs the contractor license or registration your state issues on top of it, usually with a surety bond and a certificate of insurance filed before it's granted — the table below has five states' rules.
The tools you already own, plus the big three
Your hand tools, a press or crimp tool, a drain machine for the calls that pay the fastest, an inspection camera that sells the sewer job, a pipe threader or a PEX kit for your market — bought used where you can.
A van, stocked for the ten common jobs
The vehicle you already drive at first, then a cargo van shelved with the fittings, valves, supply lines, a disposal and a water heater that let most calls finish in one visit — the stock is what makes the day pay.
Registration and the EIN
An LLC or a DBA with your state, the free EIN from the IRS, a business bank account, and the city business license or contractor registration where your city wants one — before the first paid call.
Liability, auto and comp
General liability — the permit office, the property manager and the general contractor all ask for the certificate — commercial auto for the van, and workers' comp the day you hire the first apprentice.
A price book, and a way to be found
A service-call fee, flat prices for your twenty most common jobs and a higher after-hours rate, a Google Business Profile, and a website with your license number, your prices and a quote form, plus lettering on the van.

THE STEPS
How to start a plumbing business (step by step)
Eight steps from a licensed plumber with a toolbox to a stocked van, a price book and a property manager who calls you first.
01
Confirm the license you need to run the business
Your journeyman or master license lets you work; the business needs your state's plumbing contractor license or registration, often with a master on the license, a bond and insurance filed first. Check your state board and your city before anything else.
Before anything else02
Decide what you'll do first
Residential service and repair — leaks, clogs, water heaters, fixtures — is the fastest way to start earning: small jobs you can run alone, constant calls, and every fixed kitchen tells three neighbors. New construction and commercial come later, with the cash flow to carry 30-day invoices.
03
Register and insure the business
Form the LLC or file the DBA, get the free EIN, open the bank account, buy general liability and commercial auto, and post the bond — then apply for the contractor license with the certificates in hand.
04
Write the price book
A service-call fee, flat prices for your twenty most common jobs that the customer approves before you start, an after-hours rate, and quotes for water heaters and repipes. Check each flat price against the hours it really takes.
05
Stock the van
Shelve the van with the fittings, valves, supply lines and the water heater for the jobs you do most, open a supply-house account with delivery, and keep the drain machine and the camera on board every day.
06
Get found, and tell everyone
Put your Google Business Profile and website live with your license number, your service-call fee and a quote form, letter the van, and tell every contractor, electrician, agent and property manager you've worked with that you're taking calls.
07
Answer the phone, pull the permit, clean up
Pick up every call, pull the permit on every job that needs one and book the inspection before you leave, put down the drop cloth, and leave the kitchen cleaner than you found it — the cleanup is what earns the review.
08
Fill the calendar, then hire
Ask every finished job for the review and the referral, land a property manager or two, and hire the first apprentice once the calendar is full and the flat prices can carry a second wage.
THE COSTS
How much does it cost to start a plumbing business?
The total is our free plumbing business plan's itemized US ranges for one licensed plumber going out alone: the contractor license and bond, a year of general liability — commercial auto at the high end — a drain machine at the low end and the press tool, PEX kit and threader at the high end, van stock and shelving, registration, a city license, the website, software, and two months of running costs. The van itself and your own living costs come on top. Fees from the states' own pages, insurance from Insureon, tools from five dealers' pages; checked October 2026.
$6,316–$29,590to start as one licensed plumber — the low end is Texas's $225 master-plumber designation, a $925.99 drain machine, a year of liability cover and a $40 LLC in the van you already drive
$925.99a RIDGID K-45 drain machine with cables and a tool set (Haus of Tools); a Milwaukee press tool kit is $4,199, a PEX expansion kit $499, a power threader $2,259.20, October 2026
$1,768/yraverage general liability for plumbing businesses (Insureon, August 2026) — commercial auto averages $3,415; Texas requires $300,000 of cover to run a company
$25,000California's contractor bond — the premium, not the face value, is what you pay: $100 a year on Insureon's average for plumbers' bonds
WHAT WE'VE LEARNED
What actually makes a homeowner call a plumber
Thousands of local business websites in, the pattern for plumbing is plain: the customer wants to know you're licensed, what showing up costs, and that you'll answer today. Three things on a page decide who gets the call.
A license number and a phone number
Your state license number where a homeowner can see it, your insurance, and a call button at the top of every page on a phone — the three things checked in the ten seconds before the call.
The service-call fee, and flat prices
What it costs for you to come out, whether that's credited to the job, and a flat starting price for the common jobs — a water heater, a disposal, a clogged drain — so the calls you get already expect the number.
Today, and the towns you cover
Same-day or 24/7 if you offer it, the towns you drive to, photos of real jobs and reviews that mention the town — so the homeowner knows you're real, nearby and coming.
THE UPSIDE
What a plumbing business can earn
Prices from Fixr (January 2025 and January 2026) and Housecall Pro's pricing guide (a field-service software company); revenue from a franchisor's disclosure as read by a directory and from one owner's interview; pay from O*NET. Ranges and averages, not a promise — your price book, your callbacks and how long contractors take to pay decide it. No public survey reports what one-van plumbing owners take home.
$90/hrthe average plumber's rate in Fixr's January 2025 US figures — most between $75 and $150, a master up to $200
$1,400a tank water heater installed, averaging — most between $900 and $3,000 (Fixr, January 2026); one Denver company charges $2,100
$656,635average revenue per Benjamin Franklin Plumbing territory in 2025, in a directory's reading of its disclosure — franchisees, not one-van owners
$63,800a year: the 2025 US median for plumbers, pipefitters and steamfitters (O*NET) — the pay to beat; a supervisor's is $79,920

- Pick residential service first — leaks, clogs, water heaters, fixtures.
- Write your price book — service-call fee, flat prices for twenty jobs, an after-hours rate.
- Stock the van and open a supply account — fittings, valves, a water heater, the drain machine, the camera.
- Get found — website and Google Business Profile live with your license number, van lettered, every contractor told.

Frequently asked questions
How much money do I need to start a plumbing business?
In the US, about $6,316 to $29,590 for one licensed plumber going out alone, in our plumbing business plan's itemized ranges — the contractor license and bond ($225 for Texas's master-plumber designation to about $750 for California's C-36 with its $25,000 bond's premium), a year of general liability (Insureon's average is $1,768; commercial auto adds $3,415 at the high end), the tools ($925.99 for a drain machine to $7,883 with a press tool, PEX kit and threader), van stock and a $584 shelving unit, registration ($40 in Kentucky to $890 in California), a city license, the website, software, and two months of running costs. The van itself comes on top — a new Sprinter starts at $48,990, and most owners start in the vehicle they already drive. Housecall Pro's start guide puts the whole start at $10,000 to over $50,000; Stripe's at $3,000 to $20,000 or more.
How much do plumbers charge?
In the US, $75 to $150 an hour, averaging $90 — an apprentice $20 to $40, a journeyman $45 to $90, a master $70 to $200 — with a service call of $50 to $300 and an emergency rate around $150 an hour plus a $200 to $300 call-out (Fixr, January 2025). Housecall Pro's pricing guide puts residential work at $75 to $150 an hour, the service-call fee at $50 to $250 and emergency dispatch at $150 to $400 (October 2026). One Denver company charges a $95 diagnosis and $295 to snake a main line.
How much does it cost to install a water heater?
Fixr's national average is $1,400 installed, most between $900 and $3,000 for a gas tank — $600 to $2,500 for a tank, $1,000 to $4,000 tankless — with labor $300 to $1,500 of the total and the permit $25 to $1,500 (January 2026). Housecall Pro's guide puts a tank at $900 to $3,000 and a tankless at $1,400 to $5,600. One Denver company charges $2,100 for a standard 50-gallon tank installed and $8,000 for a tankless; an Atlanta company's guideline starts at $1,600.
Is a plumbing business profitable?
It can be, but no public survey reports one-van owners' profits. What's public: plumbers charge $75 to $150 an hour and a water heater install averages $1,400 (Fixr); Benjamin Franklin Plumbing's franchisees averaged $656,635 in revenue per territory in 2025, in a directory's reading of its disclosure; and Insureon's averages for the trade are $147 a month for general liability and $285 for commercial auto. The owners quoted here say the same thing: service work paid the same day is profitable, construction paid in 30 to 45 days eats the cash, and payroll grows faster than profit.
How much do plumbing business owners make?
No public survey reports it. As an employee, a plumber, pipefitter or steamfitter earned a 2025 median of $30.67 an hour, $63,800 a year, and a construction trades supervisor $79,920 (O*NET). One Arizona owner says he didn't pay himself much for about a year after going out on his own; one Alabama owner's three-truck company does about $800,000 a year in revenue (a software company's interview, 2026). The owner's income is what's left after the van, the insurance, the stock and the apprentice.
Do you need a license to own a plumbing company?
In the US, the plumber needs a license and the company needs its own layer — and it differs by state. Texas: any company offering plumbing must secure a responsible master plumber ($225 to apply, $300,000 of liability cover). California: a C-36 contractor license once a job reaches $1,000 or needs a permit, with a $25,000 bond and four years of journey-level experience. Florida: a certified or registered plumbing contractor with $100,000 of liability cover. New York City: a Licensed Master Plumber who owns at least 51% of the company. Washington: a state contractor license with a $6,000 bond. Illinois: a $150 yearly registration with a $20,000 bond. Check your state board and your city before you print a business card.
How do I get a plumbing contractor license?
In the US, from your state's board — or your city's, where the state issues none — and it usually rests on a master or a qualifier. In the states we read: Texas has the company secure a responsible master plumber ($225 to apply, $300,000 of liability cover); California wants four years at journey level for the C-36, a $450 application, a $200 license and a $25,000 bond; Florida four years with one as a foreman, $100,000 of liability cover and a 660 credit score or a 14-hour financial course; Washington a $148.10 application, a $6,000 bond and a designated certified plumber; Illinois a $150 yearly registration with a $20,000 bond; Kentucky a licensed master plumber in responsible charge and $250,000 of liability cover. Pennsylvania issues no state license, so Philadelphia licenses the master plumber ($303, a year as a city journeyman, $500,000 of liability cover). Check your state board and your city before you apply.
Can I own a plumbing business without being a plumber?
In the US, in some states, with a licensed plumber on record. In Texas, the statute says the company secures a responsible master plumber — nothing in it requires the owner to be the master, though no page says so in words; in California, the C-36 can be qualified by a responsible managing employee working at least 32 hours a week, with an extra $25,000 bond; in Washington, the designated plumber may be an owner or a full-time employee. New York City goes the other way: the licensee must own at least 51% of the company. Read your state's rule before you pick a partner, and remember the license number goes on every van and ad in Texas.
What insurance and bond does a plumbing business need?
In the US, general liability first — Insureon's average for plumbing businesses is $147 a month ($1,768 a year); NEXT's customers pay $75 a month on average — and in Texas ($300,000), Florida ($100,000), Illinois ($100,000) and New York City ($1,000,000) the license itself requires a minimum. Add commercial auto for the van ($285 a month), tools cover ($42) and workers' comp ($179 a month) once you hire — from the first employee in California, optional in Texas. The bond is what the state requires before it issues the contractor license: $25,000 in California, $6,000 in Washington, $20,000 in Illinois — you pay a yearly premium, about $100 on Insureon's average, not the face value.
What software do plumbing businesses use?
Three kinds, and a one-truck plumber can start with fewer. Field-service software runs the day — Jobber, Housecall Pro and ServiceTitan are the names that come up first, with BuildOps on commercial work — taking the call or online request, putting it on the schedule, sending the tech, quoting at the sink, invoicing on the spot, collecting the card and keeping every customer's history. Accounting software keeps the books, the sales tax and payroll. The third is how a homeowner with a burst pipe finds you: a website and a Google Business Profile. Zarla builds the website from one sentence, with its own contact form, booking and quotes landing in a leads inbox, your calendar and your email, and invoices sent from the same place — it isn't dispatch software, and it doesn't send jobs into Jobber or Housecall Pro, so if one of those already runs your day, link the site's buttons to its request and booking pages instead. More in our guide to a Jobber or Housecall Pro website versus a real one.
Should I price plumbing jobs flat-rate or by the hour?
The owners quoted here price the job: a service-call fee to come out ($50 to $300 in the guides), then a flat price for the twenty most common jobs that the customer approves before the work starts, with water heaters and repipes quoted in writing and an after-hours rate at 1.5 to 3 times standard. Flat-rate pricing rewards a fast plumber and tells the customer the number up front; hourly pricing punishes speed and invites the clock-watching argument. Build the price book from the hours each job really takes, and check it reaches the $75 to $150 an hour the market pays.
Do I need an LLC for a plumbing business?
No — a sole proprietorship with a DBA is the cheapest legal start, and in some states the contractor license is issued to the individual anyway. An LLC separates your personal assets from the business, which matters in a trade where a mistake floods a house; it's $40 in Kentucky, $300 in Texas and $70 in California, where every LLC also owes $800 a year. In California, qualifying an LLC's license through an employee rather than a 10% owner adds a second $25,000 bond. Our guide to whether you need an LLC walks through the choice.
Can I start a plumbing business with no money?
Nearly, if you hold the license and the tools: one California owner started with a truck, his tools and no overhead, and the Texas master-plumber designation is $225. But plan for the contractor license and bond your state requires, general liability before the first call (Insureon's average is $147 a month), the registration fee, and the stock that lets a job finish in one visit. Our plumbing business plan's full start, with the tools and a year of insurance, is $6,316 to $29,590 — before the van.
How do I get my first plumbing customers?
Tell every contractor, electrician, real estate agent and property manager you've worked with that you're taking calls — one owner offered the first job free to earn the business and was turning work away in four months — answer the phone every time, and ask every finished job for the review. Then answer what homeowners search for: your license number, your service-call fee and the towns you cover on your website and Google Business Profile. Zarla builds the website from one sentence — a call button at the top, your services and starting prices, and a quote request form — and once you connect your Google profile, your Google rating and reviews show on the site.
