How to Start a Plumbing Business (2026)

The median plumber earned $62,970 in May 2024, and the top 10% cleared $105,150, according to the U.S. Bureau of Labor Statistics. Those numbers describe people working for someone else.

Owners who run their own trucks and set their own rates can do better, but only after clearing the licensing, insurance, and cash-flow hurdles that sink a lot of new shops in year one.

So what does it actually take to go from journeyman to owner in 2026?

Key takeaways

• Most states require a license to work as a plumber, and you usually climb from apprentice to journeyman to master before you can pull permits and run a shop. A few states (Kansas, Wyoming, Missouri) leave licensing to cities instead.
• A lean solo startup runs about $10,000 to $20,000, while a growth-minded launch with a reliable van, quality tools, and real marketing lands closer to $30,000 to $50,000 (Housecall Pro, ZenBusiness).
• The U.S. plumbers industry was worth $208.1 billion in 2026, growing at a 4.9% compound annual rate since 2021 (IBISWorld). There is room for one more truck.

What does the plumbing market look like in 2026?

The U.S. plumbers industry hit $208.1 billion in revenue in 2026, up 0.5% for the year, with a 4.9% compound annual growth rate since 2021 (IBISWorld). More than 132,000 plumbing businesses employ roughly 736,000 people nationwide (Simpro).

That is a big, fragmented market. Most of it is small operators, which is exactly the gap a new one-truck shop fills.

Demand holds up because pipes fail on their own schedule. Aging housing stock, water heaters that die on a Sunday, and slab leaks do not wait for a good economy. That steadiness is why plumbing pay sits above a lot of the trades.

What license do you need to start a plumbing business?

Most states require a plumbing license to work at all, and nearly all of them make you own a master license (or employ someone who holds one) before you can pull permits and run a company. The path runs in three steps.

Skip a rung and you cannot legally do the work you are billing for.

Apprentice to journeyman to master

You start as an apprentice under a licensed journeyman or master, and that stretch usually lasts four to five years. A journeyman license typically takes around 8,000 hours (roughly four years) plus a passing exam, and it lets you work on your own.

The master license sits on top: one to three more years of experience and a harder test, and in most states it is the credential that lets you pull permits and hold a contractor license (ServiceTitan, Embroker).

Rules vary hard by state. New York City wants seven years toward a master license. A handful of states, including Kansas, Wyoming, and Missouri, have no statewide plumbing license and hand the job to individual cities. Check your state board before you spend a dollar on anything else.

How much does it cost to start a plumbing business?

Plan for $10,000 to $20,000 if you go lean with used gear and a small marketing budget, or $30,000 to $50,000 for a proper launch with a dependable van, quality tools, and real advertising (Housecall Pro, ZenBusiness).

The single biggest line is almost always the truck. Everything else scales with how fast you want to grow.

Where the money goes

A used cargo van runs $3,000 to $20,000 depending on mileage, and wrapping it in your branding adds $500 to $2,000.

On tools, a budget of $2,000 to $5,000 for hand and power gear (pipe wrenches, cutters, a powered drain auger, a soldering kit, a cordless drill) covers about 80% of residential service calls.

Stock the van with $500 to $4,000 of common fittings, valves, and pipe so you finish most repairs in one trip.

How do you set up the business legally?

Form an LLC first. It separates your house and savings from a job that goes wrong, and it costs a few hundred dollars in most states plus an annual fee.

Then line up three things before you take a single call: insurance, a surety bond where your state or city requires one, and your EIN for taxes and payroll.

Insurance and bond

Plumbing business insurance averages about $189 per month, or $2,269 a year, though a solo residential operator often pays closer to $150 to $200 (MoneyGeek). General liability alone runs about $75 a month on average.

Once you hire a crew, workers compensation gets added at roughly $3.05 per $100 of payroll, and commercial auto on a service van runs $1,200 to $3,000 a year.

Many states and cities also make you post a surety bond to hold a contractor license. Bond amounts commonly range from $3,000 to $25,000 (California requires $25,000, Washington $12,000), and you pay a premium of roughly 1% to 3% of that amount each year.

Good credit gets you the low end, sometimes as little as $141 annually (Lance Surety Bonds). The bond protects your customer, not you, so budget for it as a cost of doing business.

How should you price jobs and land your first customers?

Price to cover your fully loaded cost per hour, not just your wage. Add up insurance, van payment, fuel, software, and the hours you spend quoting and driving, then divide by billable hours to find your true break-even rate.

Flat-rate pricing per job usually beats hourly for residential work because it removes the customer’s fear of a ticking clock and rewards you for being fast.

For the first customers, lean on the network you already have. Tell every general contractor, real estate agent, and property manager you know that you are open. Claim a Google Business Profile the same week you launch, because local search is where most emergency plumbing calls start.

Ask for a review after every clean job. Reviews are the cheapest marketing a new plumber will ever buy.

What software runs a one-truck plumbing business?

You can run a solo shop on $50 to $200 a month of field software that handles scheduling, dispatch, quoting, and invoicing (Housecall Pro). Doing that work by hand costs you billable hours and lost tickets. The right tool depends on how big you plan to get.

For a lean owner-operator who wants clean quotes and fast mobile invoicing, Jobber and Housecall Pro are the usual starting points, and both scale to a small crew.

If you already picture a fleet with call-center-grade dispatch and detailed reporting, ServiceTitan is built for that scale, though it is heavier and quote-only on price. Service Fusion sits in the middle for shops that want flat-rate pricing books without enterprise complexity.

Frequently asked questions

Do I need a master plumber license to own a plumbing business?

In most states, yes, either you hold a master license or you employ a master plumber who acts as the qualifying party for the company. A master license typically takes one to three years of experience beyond your journeyman and a harder exam (ServiceTitan).

A few states leave the rules to individual cities, so confirm with your local board.

How much can a plumbing business owner make?

Employed plumbers earn a median of $62,970, with the top 10% above $105,150 (BLS, May 2024).

Owners can earn more because they keep the margin on every truck, but that upside only shows up after you cover insurance averaging $2,269 a year, a van payment, and payroll if you hire.

Is plumbing a growing field?

Yes. The U.S. plumbers industry reached $208.1 billion in 2026 with a 4.9% compound annual growth rate since 2021 (IBISWorld), and BLS projects 4% employment growth for plumbers from 2024 to 2034. Aging housing and constant emergency repairs keep demand steady.

How much should I keep in cash before I launch?

Beyond your $10,000 to $30,000 in startup costs, keep enough to cover three to six months of personal and business bills. Customers pay slowly, and your first month of insurance, bond premium, and software (often $200 to $400 combined) comes due before your invoices clear.

The bottom line

Starting a plumbing business is less about the trade and more about the paperwork and the math around it. You already know how to fix a leak.

The work now is getting the master license your state expects, funding a van and tools without going broke, and pricing jobs to actually clear a profit after insurance and bond.

Get those three right, put cheap software behind your scheduling, and a one-truck shop is a realistic path in a $208 billion market.
