A master plumber license is worth the most when you bill for it yourself, and only if you can sell about 1,000 hours a year at well above your old wage. On payroll, the median plumber makes $37.61 an hour in New Jersey and $30.67 nationally, and the 90th percentile is $65.73 and $52.13 (BLS doesn't count masters separately).¹ To start a plumbing business in New Jersey there's no separate contractor license to buy. You own at least 10% of the company, register as its bona fide representative, keep a $3,000 bond and letter the van.^{2, 3, 4, 5, 6}

"I just got my master license and im trying to figure out if i can get a raise at my company or try to go on my own, super stressful," a plumber wrote on Reddit in October 2025.⁷ This page puts numbers on each way forward: stay and get paid for the license, start your own plumbing business, or let a company use your license as its master. New Jersey's rules come first, then a table for Virginia, Minnesota, Colorado, Louisiana, Nebraska and Iowa.

I read every first-person post I could find on Reddit from plumbers who had just passed the master exam or were about to, from August 2024 to November 2026: 33 statements in about 28 threads. Twelve had gone out on their own and nine were about to. Nine stayed on payroll, and three held the license for their employer. These are people who chose to write about it, so treat the counts as a mix of what people did. They aren't odds.

Path 1: stay and ask for a raise. What a master plumber's salary looks like

BLS publishes one wage series for plumbers, pipefitters and steamfitters, employees only, with no split between apprentices, journeymen and masters.¹ So no official number says what a master earns on payroll. What it does show is how high the ladder goes where you work:

In New Jersey the 75th percentile is $51.36 an hour, or $106,830 a year; nationally it's $40.92.¹ For a licensed master who runs jobs and signs permits, I'd anchor a raise near the 75th and wouldn't settle at the median. That's my reading of the numbers; BLS has no master category.

The ceiling is the usual reason people leave. One plumber wrote in May: "I got my Master's license in 23 making $36hr, i decided to shop around and realized our local pay scale topped out at around $40hr. Long story short, i had my own truck, tools, license, and insurance, why would i settle for that? Im 2 years into running my own solo business."⁸ From $36 to $40 is 11%, for a license that took years.

Staying works for some. Asked whether anything changed after the master license, a union plumber who'd moved into project management said: "Not really, I just needed it for my resume. I was making top dollar." When someone replied that the difference is your paycheck, because you can open your own business, he answered: "That's only if you getting paid like shit in the first place."⁹ Union scale and an office job changed his math. Veterans still tell journeymen to get the license either way: "Do yourself a favor and get your masters when you can, even if you don't plan on going into business for yourself. A bunch of older guys I've met over the years always say they regret it."¹⁰

Before you ask

• Bring your state's 75th and 90th percentile, and the offer you'd take elsewhere. The plumber above found his ceiling by shopping around.
• Know what your license is worth to the company. If the owner is a master, yours is a spare. If the company's only master is retiring, it needs you to keep operating, and that's Path 3, with different numbers.
• Settle side work in writing. In New Jersey, answering a question from the Department of Community Affairs in June 2025, the board said: "If the licensee is using his license to earn money in exchange for services provided, it requires the licensee to register as a Bona Fide Representative."¹¹ A bona fide representative serves "only one plumbing contractor."¹² So side jobs mean a registered business of your own, and they're off the table if you're already your employer's bona fide representative. In Minnesota a company's master on W-2 "cannot be employed as a plumber by any other contractor," and in Colorado a master can't be "responsible for more than one plumbing contractor at a time."^{13, 14}

Path 2: how to start a plumbing business with your master license

Most of the 33 went this way. "In my state you are required to hold a master's license to open a legit business. I am 18 months into running my own plumbing business as a one man company at the age of 31," one wrote.¹⁵ Another: "Boss retired, got my masters (minimum 5 years required) and opened my own company. Now I average $175 per (working) hour."¹⁶ Keep the word "working" in mind; the first-year math below is about it. First, what the business needs by law.

What a New Jersey plumbing business legally needs

"Here in NJ you need to be a master plumber to start a one man show," one New Jersey plumber wrote in 2024.¹⁷ True, and it's most of the rule. New Jersey licenses the person. A "plumbing contractor" is either a master working as a sole proprietor or a company with a master acting as its bona fide representative, and there's no separate company license.^{2, 3} The board's FAQ asks "Do I need a license as a master plumber contractor?" and answers with the rule that plumbing "shall only be performed by a master plumber, an authorized plumbing contractor, or by employees whose remuneration is reported on a Form W-2."^{18, 19} In practice that comes to 12 steps:

1. Own at least 10% of the business. The statute wants the master to hold "not less than 10%" of the shares, capital or ownership, and the board's rule spells it out: 10% of the net profits, a 10% equity interest and 10% of the proceeds if the business is sold.^{2, 3} In your own company you're well past it.
2. Form the business. The board's registration form asks a sole proprietor for a trade name certificate from the county clerk, an LLC for its certificate of formation, and a corporation for its certificate of incorporation and a stock certificate.²⁰ Then register for state taxes with the Division of Revenue and Enterprise Services, which "All businesses must" do.²¹
3. Register as the bona fide representative within 30 days of taking the role. The notarized form gives the business name and New Jersey address, proof of your ownership, the company's consent that you're its agent for service of process, and the company's written acceptance of liability for penalties and refunds owed to consumers.^{4, 20} The board approves these at its meetings.¹¹
4. Keep the $3,000 bond. No licensed master "shall undertake to do any plumbing work" without a $3,000 surety bond in favor of the State, and no town may ask for a similar one.⁵ In June 2025 the board's executive director said renewal bonds must name the licensee as principal and expire June 30, 2027, and that a home improvement contractor's bond won't be accepted.¹¹ A customer hurt by a master's failure to follow the plumbing law can claim on it.²²
5. One company, one New Jersey address. A bona fide representative must "Serve as a bona fide representative for only one plumbing contractor" and "Maintain a place of business in the State of New Jersey."¹²
6. Letter the van before the first call. Both sides of every commercial vehicle show the master's name and "Plumbing Lic. #" with the number, at least 1 inch high, plus the owner's name and the town you work from, at least 3 inches high.⁶
7. Put the same on paper. Invoices, letters and stationery carry the master's name, "Plumbing Lic. #" and the number, and the New Jersey street address. Every ad carries them too, and you're personally responsible for any ad with your name or number on it. If you'll sub out more than a third of your work, your ads have to say so.⁶
8. Use a written contract from $500 up. A job of $500 or more needs one, with the work, the price and the estimated start and finish dates, signed by the customer and by you or the W-2 employee doing it. A small job that grows past $500 needs one too.²³
9. Charge sales tax on repairs. The state's tax guide for contractors lists "Fixing faulty plumbing" as a repair, so the labor is taxable. A new water heater or new bathroom fixtures are exempt capital improvements once the owner hands you a Form ST-8. Either way you pay tax on your materials when you buy them.²⁴
10. Get workers' comp before your first employee. An employer without it commits a disorderly persons offense (a fourth-degree crime if it's knowing), and the state can issue a stop-work order and penalties of up to $5,000 for every 10 days.²⁵
11. Buy liability insurance. I found no minimum for master plumbers in the plumbing statute or the board's rules, so the amount is your call. Costs are below.
12. Supervise the way the rule describes. A licensed master signs every permit. A master working for you reports at the start and end of each job, journeymen get daily contact that you record, and an apprentice gets "constant on-site supervision" from a master or a supervisory journeyman. You answer for your employees' violations on work you were supposed to supervise.¹²

Two things you don't need. Plumbing work under your license doesn't need a home improvement contractor registration, because that law doesn't apply to a "master plumber ... acting within the scope of practice."²⁶ And there's no town plumber's license: no municipality has been allowed to issue one since 1987.²⁷

If you're your employer's bona fide representative now, leaving takes paperwork. The board's answer, in the same June 2025 minutes: "Notification to the Board is required in writing and it is the licensee's responsibility to close all permits."¹¹ The company you leave can keep working for 60 days under another licensee's supervision while it finds your replacement, as long as it tells the board within 10 days.⁴ Give them notice.

Your license renews every two years, by June 30 of odd-numbered years, for $160, after 5 hours of continuing education.^{18, 28} It covers more than pipe: a New Jersey master may install and repair boilers, hot water and steam heating, thermostats and natural gas piping without an HVACR license.¹⁹ What it doesn't protect is clogs. Anyone may clear a stoppage, so drain cleaners without a license compete with you there, and a home improvement company with "plumbing" or "drain" in its name can't go past that without a master.¹⁹ Break the rules and the board's penalties run up to $10,000 for a first violation and $20,000 after that, and up to $15,000 and $25,000 for transferring your license to someone else.²⁹

Starting a plumbing business in Virginia, Minnesota, Colorado, Louisiana, Nebraska or Iowa

Each of these states puts the license on the person, the company or both, and five of them stop one master from standing behind more than one company (in Nebraska it's Omaha's rule). Every row comes from a board's own page, a city code or the statute.

Virginia's rules may still limit a Qualified Individual in ways I didn't find, and Louisiana's new board will write its own rules for 2027. Check both with the board before you file.

How much does it cost to start a plumbing business?

Less cash than you'd guess, and more time. The one owner who gave a starting figure: "I started with about 10K and my personal truck/tools," and "My first couple of bigger purchases were drain machines."⁴⁵ Nobody I read put a price on the van. The other costs, from owners and the boards:

• License and registration fees: $160 every two years in New Jersey, $188 for Minnesota's contractor license, $40 a year for Nebraska's contractor registration.^{28, 13, 41}
• Bonds: $3,000 in New Jersey, $25,000 in Minnesota, $5,000 in Iowa, $10,000 in Omaha.^{5, 13, 43, 38} You pay a surety company a premium for each bond; the face amount is the most a claim can take.
• Liability insurance. A one-man plumbing company, after its first year: "My contractor's insurance (business owners policy) is up for renewal, and it would increase 50 percent (from approx $1,000, to $1,500 for a year)." Other insurers quoted him "around $2,500 or more."⁴⁶ A Colorado husband-and-wife shop: "We pay $3000/yr for liability insurance.umbrella policy and tool insurance. $3600/yr for commercial insurance on our box truck."⁴⁷ So budget $1,000 to $3,000 for the policy, with the vehicle's insurance on top. That's two owners, so treat it as a range. Louisiana's and Iowa's $500,000 minimums and Omaha's $1,000,000 certificate mean a bigger policy there.
• Self-employment tax: 15.3% of your net earnings for Social Security and Medicare, the tax that used to come out of your paycheck, now with the employer's half too (you deduct that half).⁴⁸

Then the time. "A minimum of 3 years until you start to see a steady profit, if actually a legitimate business," one owner wrote. Another, answering a new license holder: "First 3 years is the hardest."^{49, 50}

First-year numbers: about 1,000 billable hours

"Figure on 1000 billable hours a year," says a plumber who ran his own shop for about three years.⁵¹ That's about half of a 2,080-hour work year. The other half goes to driving, quoting, buying parts, invoicing and the days the phone doesn't ring. Another owner: "$100.00 service calls aren't paying the bills, as most single man shops don't have 8 billable hours every single day."⁵²

So work backwards from the paycheck you're giving up, divided by 1,000 hours:

That covers your pay and nothing else.^{1, 51} Insurance, the truck, fuel, tools, the bond, your phone, the 15.3% self-employment tax and some profit all sit on top. (BLS wages divided by one owner's rule of thumb, so your hours will differ.)

Now look at what owners charge. Nobody measures plumbing prices, so all there is to go on is what owners say:

• The service call is a minimum that covers about the first hour. Of 18 owners who stated one, it runs $100 to $325, mostly $160 to $245. A one-man shop in semi-rural Pennsylvania: "My minimum fee is $150 plus parts. That will get you an hour of labor. $75 an hour after that."⁵³
• Some credit it back: "residential service is $155 diagnostic to come out and will be taken out of cost if service is complete same day," from a shop that opened in June 2025.⁵⁴
• The only New Jersey rate sheet I found: "4 hours or less $220/hr. 8 hour day $175/hr," with $130 an hour on new construction and large renovations, "Only this low to be competitive since im usually bidding against other shops."⁵⁵

Run one through the math as an example. At $175 an hour, 1,000 billable hours bring in $175,000 before costs, and replacing New Jersey's 90th-percentile wage takes $137,000 of it. At $100 for an hour's service call, the same hours bring in $100,000 before a dollar of costs. That gap is the "working" in "$175 per (working) hour."¹⁶

Your first customers

Every "just got my license" post I found asks the same thing: where the first customers come from. None asks about pricing. "Ive been a plumber for 10 years and I'm ready to start going out on my own I'm really struggling to find clients," one wrote in March. Facebook Marketplace hadn't worked: "all the jobs I've gotten have been with angry homeowners who want a quick p trap replacement."⁵⁶ The answers that hold up:

• Property managers, HOAs and realtors. "Cold call property management and HOA maintenance/management companies and realtors. You're going to strike out a lot most of them will already have someone but some of them will take your contact for back up and if you talk to enough of them you'll find one that is sick of their current guy."⁵⁷
• Other businesses with steady work. "I would suggest that individual customers are not the right direction. You'll want to connect with new construction, property management companies, emergency restoration companies, and other folks who have institutional money."⁵⁸
• More than one of them. A one-man company a year in: "One of my biggest clients is (was?) a property management company. I usually get 1-2 repair calls from them per week, most weeks." Then: "Honestly, I am a bit desperate, because my schedule has dried up, and not just because of them."⁵⁹
• Not home warranty companies. An owner's answer to a new license holder who wanted to fill slow days with them: "Jumping through hoops to get paid, having to go to the place, diagnose, submit a diagnosis, them telling you they'll only cover like $300 of a repair, and then being on a net 60 after all that."⁶⁰
• If you buy leads, count the cost per customer. One analytics firm's numbers for Google Local Services Ads: about $57 a plumbing lead, 44% booked, about $263 per paying customer on an average ticket near $1,700. Shared lead marketplaces sell one homeowner to several plumbers: $30 to $100 a lead and a 5% to 15% close by industry estimates, or about $650 per booked job at $65 and 10%. The author sells analytics, so these are his figures.⁶¹

And the plain answer from the same thread as the first one: "If you just got your license I'd work for someone for a while first."⁶²

Path 3: be a company's license holder

Some new masters get asked before they decide. A plumber whose old owner and license holder retired was approached to take his place: "They talked about negotiating a pay raise for me but I have no clue how much to ask for."⁶³ The pay owners state is thin. "$25k a year is what we pay our master of record," one owner wrote, and the same owner later said "50k wouldn't be unreasonable" for a commercial company, because "Being the master of record for a commercial company is a tremendous amount of responsibility and liability."⁶⁴ Another: "I got 5% override of the gross on all the commercial jobs."⁶⁵ Older forum posts run from $750 a month, offered in 2016 to rent a New Jersey master's license, to "Minimum I would say is $3,500.00 per month."⁶⁶

New Jersey's rules shape this deal. Under the board's June 2025 answer, a master who earns money with the license registers as a bona fide representative, which takes 10% ownership and allows one company only.^{11, 3, 12} So a New Jersey master can't rent out his name alone, and can't be someone's bona fide representative and run his own company too. You also answer for violations by the company's employees on work you were supposed to supervise, and transferring your license to someone else carries penalties of up to $15,000 and $25,000.^{12, 29} Minnesota, Colorado, Louisiana and Iowa have one-company rules of their own (table above). A Colorado owner describes what happens anyway: "Most hire a master plumber in name only to pull permits."⁶⁷

What being the master of record pays and what it can cost you get their own article.

Before the next job

1. Pick a path this week, and take your state's numbers from the BLS table to your boss either way.
2. In New Jersey: form the business, get the $3,000 bond in your name running to June 30, 2027, register as bona fide representative within 30 days, and register for state taxes.^{20, 11, 4, 21}
3. Letter the van, and put your name, "Plumbing Lic. #" and number, and New Jersey street address on your quote, invoice and ad templates.⁶
4. Get a few insurance quotes. Owners report $1,000 to $3,000 a year for the policy.
5. Set your minimum and write down what it covers: the trip, the diagnosis, the first hour.
6. Call property managers, HOA managers and realtors near you, and expect most of them to say they already have someone.

Where Deepsel fits

Deepsel is the field service software I build, and it doesn't know plumbing law. It won't register you with the board, remind you about the bond or your continuing education, or tell you which job needs a permit. What it does for a new shop: the quote terms you write once in settings are copied onto every new quote, and the invoice footer onto every invoice, so your name, "Plumbing Lic. #" and number, and New Jersey street address print on every document without retyping. Every line on a quote or invoice is marked taxable or not, and each quote starts with your shop tax rate, which you can change on that quote or job. That fits New Jersey's split between repairs and capital improvements (keep the customer's ST-8 in your own files). One customer can have many service locations, so a property manager's buildings sit under one account, and your own request form link lets them send you work: each submission lands as a new request and emails you. Quotes can carry options, the customer approves and signs on screen, an optional card deposit is credited on the final invoice, and an approved quote becomes a job. Free covers 30 estimates and 30 invoices a month for your whole team; Pro is $29 a month with unlimited estimates and invoices (pricing).

Frequently asked questions

Do I need a plumbing contractor license in New Jersey?

Not a separate one. New Jersey licenses the master plumber, and a plumbing contractor is either a master working as a sole proprietor or a company whose bona fide representative is a master who owns at least 10% of it. Register with the State Board of Examiners of Master Plumbers within 30 days of taking that role, keep the $3,000 surety bond, keep a place of business in New Jersey and register for state taxes. Plumbing work inside your license doesn't need a home improvement contractor registration, and no town may issue a plumber's license.

Can a New Jersey master plumber work for a company and do side jobs?

Only through a registered business of his own. The board said in June 2025 that a master who uses the license to earn money in exchange for services has to register as a bona fide representative, and a bona fide representative serves only one plumbing contractor. If you're already your employer's bona fide representative, side work under your license is out. If someone else holds that role, you can register as the bona fide representative of your own sole proprietorship, with the bond, the van lettering and the paperwork that go with it. Read your employment terms too.

How much does a master plumber make?

BLS doesn't separate masters from other plumbers. For plumbers, pipefitters and steamfitters on payroll in May 2025, the median was $37.61 an hour ($78,240 a year) in New Jersey and $30.67 ($63,800) nationally. The 90th percentile was $65.73 an hour ($136,710 a year) in New Jersey and $52.13 ($108,420) nationally. Minnesota's median, $45.39, is the highest of the states in this article. A master who runs his own shop earns what he bills, minus his costs.

Can a plumber make $100,000 a year?

Yes. On payroll in New Jersey the 75th percentile is $106,830 a year, so about a quarter of the state's plumbers make more than that, and the national 90th percentile is $108,420. On your own, $100,000 of pay at about 1,000 billable hours a year means $100 an hour for you, before insurance, the truck, tools, the bond and 15.3% self-employment tax.

How much does it cost to start a plumbing business?

One owner started with about $10,000 and his personal truck and tools, and bought drain machines first. Owners report liability insurance of about $1,000 to $3,000 a year, plus the vehicle's own insurance ($3,600 a year for one couple's box truck). Bonds are $3,000 in New Jersey, $25,000 in Minnesota, $5,000 in Iowa and $10,000 in Omaha. New Jersey's license renewal is $160 every two years, and Minnesota's plumbing contractor license is $188.

Is it easy to start a plumbing business?

The paperwork is quick. In New Jersey it's a business filing, a bond, a board registration, a tax registration and lettering on the van. Customers and the first years are the hard part. One owner put it as 'First 3 years is the hardest' and another as 'A minimum of 3 years until you start to see a steady profit.' Every new license holder's post I found asked how to get the first customers, and the answers that held up were property managers, HOAs, realtors and other businesses with steady work.

How long does it take to become a master plumber in New Jersey?

At least five years from the start of a registered apprenticeship. The board wants you to be 21, to finish a four-year apprenticeship approved by the US Department of Labor, and then to work one year as a journeyman in New Jersey with at least 1,200 hours of hands-on experience. A bachelor's degree in mechanical, plumbing or sanitary engineering plus the same journeyman year also qualifies. The board reviews applications at its monthly meetings, then you sit the exam. The application fee is $100.

Should I get my master plumber license if I don't plan to start a business?

Most veterans say yes. One told a new journeyman to 'get your masters when you can, even if you don't plan on going into business for yourself,' because the older plumbers he'd met regretted not doing it. It moves you up the payroll ladder, it keeps your own business open as an option, and a company whose master is retiring may ask you to take over as its license holder.
