How to Start a Plumbing Business in Texas: DFW Guide (2026)

Texas plumbing license requirements: the TSBPE pathway

Licensing comes first because in plumbing it is the whole ballgame. Texas is not a handyman state for this trade. The Texas State Board of Plumbing Examiners (TSBPE) controls who can touch a pipe for pay, and more importantly for you, who can own the company that sends the invoice.

Here is the full ladder, bottom to top.

Step 1: Plumber's Apprentice

• Minimum age 16.
• Registration fee: $15. Renewal: $15.
• This is the entry point. Every hour you work as a registered apprentice counts toward the next tier.

If you are reading a "start a plumbing business" guide, you are probably past this step. It is here because the hours clock starts here, and because you will be hiring apprentices soon enough.

Step 2: Tradesman Plumber-Limited

• 4,000 hours working in the plumbing trade, with a current apprentice registration.
• A TSBPE-approved 24-hour training course, or enrollment in a US Department of Labor apprenticeship program instead.
• Exam application: $36. Initial license: $35. Renewal: $35.

At roughly 2,000 working hours per year, 4,000 hours is about 2 years of full-time work. That timeline is arithmetic from the hour requirement, not an official TSBPE figure. Your actual pace depends on overtime and how consistently your hours get logged.

Step 3: Journeyman Plumber

• 8,000 hours in the plumbing trade. You must already hold a Texas apprentice registration or Tradesman license.
• A TSBPE-approved 48-hour training course, or a US DOL apprenticeship program.
• Exam fee: $40. Initial license: $40. Renewal: $40.

8,000 hours is about 4 years of full-time work, again derived from the requirement itself. Most DFW plumbers sit at this tier. It pays well as a wage: $68,972 average in Dallas per ZipRecruiter (July 2026), with the 75th percentile at $78,600. It does not let you own the shop.

One fee the Tradesman and Journeyman pages leave out: TSBPE's computer-based testing FAQ states the CBT fee is $68.50, paid directly to Pearson VUE, and that for exams with a practical portion, including Tradesman-Limited and Journeyman from Apprentice, the standard TSBPE exam fee still applies in addition to the $68.50. Budget $104.50 at the Tradesman exam and $108.50 at the Journeyman exam, not the single figures the tier pages show. (source)

Step 4: Master Plumber

• Licensed as a Journeyman for at least 2 years. Cut to 1 year if you completed a US DOL-approved apprenticeship training program.
• Exam: $25 processing fee to TSBPE, plus $128.50 exam fee paid to Pearson VUE on exam day.
• Initial license: $75. Renewal: $75.

One quirk worth knowing: if you hold both Journeyman and Master licenses, you pay only the Master renewal fee, not both.

Add the tiers up and the realistic floor from a standing start is about 6 years: roughly 2 to Tradesman, 4 total to Journeyman, then 2 more holding Journeyman before the Master exam. If you are already a Journeyman with 2 years in, you are one $153.50 exam away from the license that matters.

Step 5: Responsible Master Plumber (RMP). This is the business license.

A Master license lets you work at the top of the trade. It does not let you operate a plumbing company. For that, Texas requires the Responsible Master Plumber designation:

• You must hold a current Texas Master Plumber license in good standing.
• Initial RMP application: $225. Renewal: $300.
• You can serve as RMP of record for only one company at a time. No renting your license to three shops.
• Your company name and license number must be displayed on your service vehicles.
• You are responsible for obtaining all permits and inspections on your company's work.

The insurance requirement has teeth. Texas Occupations Code Sec. 1301.3576 says it plainly: "Before a master plumber works as a responsible master plumber, the master plumber must provide the board with a certificate of insurance." No certificate on file with TSBPE, no legal operation.

Insurance minimums for a Texas plumbing company

• $300,000 minimum commercial general liability, maintained continuously, covering all claims arising in any one-year period.
• Typical cost for a Texas plumbing GL policy: $1,500 to $5,000 per year depending on revenue, crew size, and claims history.
• Ask your agent to quote $1,000,000 limits alongside the $300,000 minimum. The premium jump from $300k to $1M is often minimal, and general contractors and property managers frequently require $1M before they will put you on a job.

The full fee ledger, apprentice to RMP

Every state fee on the pathway, in the order you pay it:

Fee	Amount	Paid to
Apprentice registration	$15	TSBPE
Tradesman exam application	$36	TSBPE
Tradesman initial license	$35	TSBPE
Journeyman exam	$40	TSBPE
Journeyman initial license	$40	TSBPE
Master exam processing	$25	TSBPE
Master exam, exam day	$128.50	Pearson VUE
Master initial license	$75	TSBPE
RMP application	$225	TSBPE
Total, entry to business owner	$619.50

That total excludes the annual renewals you pay while climbing ($15 apprentice, $35 Tradesman, $40 Journeyman) and the cost of the 24-hour and 48-hour training courses, which varies by provider. It also excludes the $68.50 Pearson VUE computer-based testing fee that TSBPE's CBT FAQ confirms applies at both the Tradesman and Journeyman exams, which adds $137 across the two tiers and puts the true ledger at $756.50. (source) Even with those added, the state charges you less to become a plumbing business owner over 6 years than one slab leak repair pays in a day. The barrier is the hours, not the money.

Moving to Texas with an out-of-state license

If you hold a current Journeyman or Master license from another state, TSBPE exempts you from the 24-hour (Tradesman) and 48-hour (Journeyman) training-course requirements. You still test in Texas. For a licensed plumber relocating to DFW, that removes the most time-consuming classroom obstacle.

Endorsements that raise your ticket size later

TSBPE issues three endorsements a growing company can add: Medical Gas Piping Installation, Multipurpose Residential Fire Protection Sprinkler Specialist, and Water Supply Protection Specialist. None are required to open, and none belong in your first-90-days plan.

They belong in your year-two plan. Each endorsement narrows the field of shops legally allowed to bid a category of work: medical gas piping for healthcare facilities, residential fire sprinkler systems, and water supply protection. Fewer eligible bidders means less price competition on those jobs than on the drain-cleaning calls every shop in DFW chases. When your service revenue is steady, pull the current endorsement requirements from TSBPE and price out the one that fits the commercial work already in your area.

City contractor registration in DFW: office, form, fee

State licensing gets you legal in Texas. Pulling permits gets decided city by city. Here is what the four biggest DFW cities require:

City	Office	What you file	Fee
Fort Worth	Development Services Department, 817-392-2222	Contractor registration (Building, Plumbing, Irrigators, Sign, Moving & Wrecking Contractors class); requires a valid Texas Master Plumber license	$168.75 per year
Plano	Building Inspections Department, 972-941-7140	Contractor registration; show your current Texas state plumbing license and driver's license	$0. The city's handout states "No registration fee will be assessed" for state-licensed plumbing contractors
Dallas	Building Inspection, 320 E. Jefferson Blvd, 214-948-4480	Contractor registration; the registered Responsible Master Plumber validates each plumbing permit	$0. Texas Occupations Code Sec. 1301.551(g) bars any city from charging a plumbing registration or administrative fee, and neither the city's registration form nor its current fee schedule lists one (source)
Arlington	Planning and Development Services (permits via ArlingtonPermits.com)	General business registration; no plumbing-specific contractor registration appears in the Oct 2025 fee schedule	$35 for 1 year general business registration; $100 per-trade fee applies on new-construction permits. Plumbing contractor registration itself carries no separate charge; Texas Occupations Code Sec. 1301.551(g) prohibits cities from charging plumbers a registration or administrative fee (source)

Plan to register in every city you regularly pull permits in, not just where your shop sits. A Plano-based company running calls in Fort Worth needs the Fort Worth registration.

What it costs to start a plumbing business in Texas

The paperwork is cheaper than most tradesmen expect. Here is the itemized state and local stack for a Journeyman going all the way to an operating company, using current published fees:

Licensing and legal costs

Item	Cost	Frequency
Master Plumber exam (TSBPE processing)	$25	One time
Master Plumber exam (Pearson VUE, exam day)	$128.50	One time
Master Plumber initial license	$75	Then $75/yr renewal
Responsible Master Plumber application	$225	Then $300/yr renewal
Texas LLC, Certificate of Formation (Form 205, Secretary of State)	$300	One time
Fort Worth contractor registration	$168.75	Annual
Plano contractor registration	$0	Annual (still must register)
Dallas contractor registration	$0	Annual (still must register)
Arlington general business registration	$35	1 year
State and local subtotal (excluding Dallas)	$957.25	First year

Insurance

Item	Cost	Notes
Commercial general liability, $300,000 minimum	$1,500 to $5,000 per year	Required by TSBPE before you operate as RMP. Certificate must be on file with the Board. Quote $1M limits; the premium difference is often small

Year two and beyond: the recurring stack

Budget the renewals now, because two of them cost more than the fees that got you started:

Item	Annual cost
Master Plumber license renewal	$75
RMP renewal	$300
Fort Worth contractor registration	$168.75
Arlington general business registration	$35
Plano contractor registration	$0
Dallas contractor registration	$0
Commercial general liability policy	$1,500 to $5,000
Recurring total (excluding Dallas)	$2,078.75 to $5,578.75

Two things to notice. First, the RMP renewal is $300 against a $225 initial application, so the designation gets more expensive to keep than to get. Second, the license-and-registration side of the stack is $578.75 a year, which one mid-range water heater replacement covers with room to spare at DFW pricing. Insurance is the only recurring line big enough to feel, and letting it lapse does more than raise your risk: continuous coverage is a TSBPE condition of operating as an RMP, so a lapsed policy means a company that cannot legally work.

Truck, tools, and working capital

Item	Cost
Service van or truck (owned or financed)	$12,000 to $20,000 for a mid-mileage used Transit in DFW; CarGurus Dallas listings run $8,743 to $56,100 with an average near $26,200 (a 2015 at 129k miles listed at $11,925, a 2019 at 62k miles at $19,225) (source)
Vehicle lettering with company name and license number (TSBPE requirement)	$150 to $400 for basic name-and-license lettering per Express Signs & Graphics' published price guide; Dallas shops quote partial wraps at $500 to $1,200 and full van wraps from $1,800 (Zolik Signs, Dallas) (source)
Tool and equipment gap-fill beyond what you own	[VERIFY: itemize against the equipment list below]
Operating cash reserve (fuel, parts, insurance premium, 60 to 90 days of personal bills)	[VERIFY: build from your own household number]

No invented figures here. The licensing column is exact because TSBPE and the cities publish it. The truck-and-tools column depends entirely on what you already own after 6+ years in the trade, which is why the calculator below asks instead of assuming.

Run your own numbers before you quote your spouse a figure. Here is one worked example so you can sanity-check the calculator's output. A Journeyman with 2 years in, going all the way: $453.50 in remaining TSBPE fees (Master exam, license, RMP), $300 for the LLC, Fort Worth plus Arlington plus Plano registrations at $203.75, and a $3,250 GL premium at the midpoint of the verified range. Total: $4,207.25 before the truck. At a billed rate of $110 per hour, the midpoint of the DFW range, that is about 38 billed hours to cover it. At the $1,900 midpoint of Crown's water heater range, it is under three water heater replacements in gross revenue. Gross is not net, since parts, fuel, and the premium itself come out of those tickets, but the order of magnitude is the point: the paperwork side of this business pays itself back in weeks, not years.

The launch sequence: from Master license to first invoice

Do these in order. Several steps block the ones after them.

1. Pass the Master exam and get the license in hand. $25 to TSBPE, $128.50 to Pearson VUE, $75 initial license. Nothing else starts until this exists.
2. Form the entity. File Form 205 with the Texas Secretary of State, $300, and your LLC exists. Get the EIN from the IRS (free) and open a business bank account. Keep company money and personal money separated from day one; commingled accounts kill liability protection.
3. Buy the general liability policy. $300,000 minimum CGL, continuous coverage. Get the certificate of insurance issued in the company's name.
4. File the certificate with TSBPE and apply for RMP. $225 application. Sec. 1301.3576 makes the certificate a precondition, so steps 3 and 4 happen in that order. Once approved, you are the RMP of record for your company, and only your company.
5. Letter the truck. Company name and license number on service vehicles is a TSBPE requirement for RMPs, not a branding suggestion. Do it right the first time; the truck is a rolling billboard you already paid for.
6. Register with every city you will pull permits in. Fort Worth ($168.75), Plano ($0), Dallas ($0 (source)), Arlington ($35 business registration). Bring your state license; Plano also wants your driver's license.
7. Set your rate card. Use the DFW rate table below. Price at the market, not under it. An owner-operator billing $75/hour has bought a job, not built a company.
8. Stand up your Google Business Profile and website. This is where the phone calls come from now. A licensed, insured RMP with no Maps presence is invisible to every homeowner typing "plumber near me" at 9 pm with water on the floor.
9. Book the first jobs. Tactics in the first-customers section below.

A Journeyman with 2 years in can realistically clear steps 1 through 6 in a single quarter. TSBPE's published exam guide has scores emailed within three business days of testing and the new license card mailed within 7 to 10 business days; the Board publishes no processing timeline for the RMP application itself, so leave slack in the plan before promising a start date.

What DFW plumbing companies actually charge in 2026

Your pricing floor is set by what the market already pays. These are published or reported rates from five DFW-area sources:

Service	Low	High	Source
Hourly rate, residential service	$90/hr	$150/hr	Crown Plumbing Service (DFW/Prosper)
Hourly rate, licensed plumber	$75/hr	$150/hr	Piece of Mind Plumbing (Decatur/DFW)
Hourly rate, standard (emergency $150 to $250/hr)	$75/hr	$150/hr	Craftsman Plumbing (Dallas)
Hourly rate, Dallas market-wide	$45/hr	$250/hr	HomeGuide Dallas (June 2026)
Service call / trip fee	$50	$95	Crown Plumbing Service
Service call fee, credited toward repair	$50	$100	Craftsman Plumbing
Service call fee, Dallas market-wide	$100	$250	HomeGuide Dallas
Water heater replacement, 40-50 gal tank	$1,400	$2,400	Crown Plumbing Service
Water heater replacement	$1,200	$3,800+	Piece of Mind Plumbing
Water heater install (tank from $1,776; customer-supplied from $683; tankless from $5,292)	$683	$5,292+	Benjamin Franklin Plumbing (Fort Worth published price list)
Drain cleaning	$100	$450	Craftsman, Piece of Mind, Crown, Benjamin Franklin (from $209)
Toilet install (round from $605, elongated from $665, customer-supplied from $405)	$405	$665+	Benjamin Franklin Plumbing (Fort Worth)
Kitchen faucet replacement	$180	$350	Crown Plumbing Service
Slab leak repair (detection alone $250 to $500)	$1,200	$4,000+	Piece of Mind Plumbing, Crown
Sewer line repair (full replacement $3,750 to $30,000+ per HomeGuide)	$1,500	$5,000+	Craftsman Plumbing, HomeGuide Dallas
Hydro jetting	$688 starting	n/a	Benjamin Franklin Plumbing (Fort Worth)

Three things to take from this table:

• The spread is the business. A journeyman wage in Dallas averages $33.16/hour (ZipRecruiter) or $32.35/hour plus about $6,750 in annual overtime (Indeed, 111 reported salaries). Established shops bill that same hour at $90 to $150. The difference, minus truck, insurance, parts, and marketing, is what ownership pays.
• Trip fees are standard. $50 to $100, usually credited to the repair. Charge one. It filters tire-kickers and pays for windshield time.
• Big-ticket work is where the year is made. Water heaters at $1,400 to $2,400, slab leaks at $1,200 to $4,000+, sewer lines at $1,500 to $5,000+. Ten service calls fund the week; two water heaters fund the month's insurance.

For context on the labor market you will hire from: DFW's all-occupations mean wage is $32.89/hour (BLS OEWS, May 2024), almost exactly what plumbers average, and BLS projects 4% national employment growth for plumbers from 2024 to 2034 on a $62,970 national median. Demand is not the problem. Visibility is.

Hourly, flat-rate, or trip fee plus quote

The five sources in the table above are not all pricing the same way, and the difference matters when you build your rate card.

Crown, Piece of Mind, and Craftsman publish hourly ranges: $75 to $150 for standard work, with Craftsman's emergency rate at $150 to $250. Benjamin Franklin of Fort Worth publishes flat prices instead: a round toilet installed from $605, a tank water heater from $1,776, hydro jetting from $688. Same market, two models. Hourly is easier to quote and easier for a customer to dispute when a job runs long. Flat-rate takes more setup, since you need a price for every common job, but the customer agrees to a number before you start and your speed becomes your margin instead of your penalty.

The hybrid most DFW shops run: a trip fee of $50 to $100 to get the truck rolling, credited toward the repair if the customer approves the quote, then a flat price for the job itself. Craftsman publishes exactly this structure. It protects your windshield time on no-sale calls and keeps the invoice conversation short on the rest.

One more read on the table: HomeGuide's Dallas-wide hourly span is $45 to $250, far wider than any single company's published range. The $45 end is unlicensed or uninsured operators you are not competing with, and the $250 end is emergency and specialty work. Price against the $75 to $150 the established licensed shops publish, not against the extremes.

The math on your first hire

Your second truck is where the business stops being a job. The inputs are all in the data above. A Dallas journeyman costs $68,972 a year on average per ZipRecruiter, and Indeed's figure from 111 reported salaries is $32.35 an hour plus about $6,750 in overtime. Call it roughly $33 an hour before payroll taxes and insurance. That same hour bills at $90 to $150 at established DFW shops.

The spread does not all reach you. The hire needs a stocked van, fuel, added GL exposure, and enough booked calls to stay billable, and no service plumber bills every hour of an 8-hour day. But the direction is clear: every billable hour a journeyman works for you carries a wage-to-rate gap of roughly $57 to $117, and that gap is what pays for the truck, the overhead, and eventually you stepping off the tools.

Recruiting is the hard part. DFW's mean wage across all occupations is $32.89 an hour, which means a journeyman plumber earns almost exactly the metro average and has options in every trade. BLS projects 4% national growth in plumbing employment from 2024 to 2034, so the pool is not getting deeper. The shops that win hires post the wage, pay for the truck stock, and keep the schedule full enough for overtime, the same $6,750 a year of it that Indeed shows Dallas plumbers already expect.

Equipment: what a first truck needs

After 8,000+ hours you own most of your hand tools. The gap between a journeyman's bag and a service company's truck is usually this list:

• Service van or high-roof truck with shelving. CarGurus Dallas listings for used Transit cargo vans run $8,743 to $56,100, averaging near $26,200; a mid-mileage work unit lands around $12,000 to $20,000. (source)
• Drain machines. A handheld or drum auger for sinks and tubs plus a mainline machine. Drain cleaning bills $100 to $450 per job in this market and is the most common entry call, so this pays back fast.
• Press tool or torch setup for repipes and water heater swaps, per your preferred method.
• Leak detection gear if you want slab leak work. Detection alone bills $250 to $500 in DFW (Crown), and the repairs behind it run $1,200 to $4,000+.
• Camera and locator for sewer work, or plan to sub inspections until volume justifies buying.
• Stock: water heater install kits, supply lines, stops, wax rings, common repair parts. Every parts-house run mid-job is unbilled time.
• Lettering and uniforms. The truck lettering is a TSBPE requirement anyway; matching shirts make you look like the $150/hour shop instead of the $75/hour guy.

Buy the drain machines and the water heater setup first. They match the two highest-frequency, best-margin residential calls in the rate table above.

Getting your first customers in DFW

You need two engines: one that produces calls this month, and one that compounds.

This month:

• Tell every GC, remodeler, and property manager you have ever worked under that you are licensed, insured, and taking overflow. Your RMP status and $300,000+ COI are the credentials they need to hand you work.
• Answer the phone. DFW shops charging $100+ trip fees still miss calls. The first company that picks up gets the water heater job. Set up call forwarding and answer after hours; emergency work bills $150 to $250/hour at Craftsman's published Dallas rates.
• Ask for the review on every completed job, standing in the customer's kitchen, link ready to text. Reviews are the currency of the compounding engine below.

Compounding:

• Google Business Profile, fully built. Correct categories, service list, photos of real jobs, every review answered. Maps placement decides who gets the "plumber near me" call, and that call is worth $50 to $250 before you touch a wrench.
• A website that books jobs. Not a brochure. Pages for your actual services (water heaters, drain cleaning, slab leaks) and cities, your license number visible, your phone number clickable, a form that reaches you in minutes.
• Service-area pages for each city you registered in. You paid Fort Worth $168.75 to pull permits there; a page targeting Fort Worth searches is how that registration turns into Fort Worth revenue.

The trap: every hour you spend fighting with a website builder is an hour you are not billing at $90 to $150. Which is the honest pitch for the next section.

Three reasons DFW plumbing owners work with On The Map

1. We get you found in Google Maps and local search. When a Plano homeowner searches "water heater replacement near me," the three companies in the map pack get the call. Our job is making yours one of them, in every city you are registered to work.
2. We build a website that turns searches into booked jobs. Service pages, city pages, click-to-call, reviews up front, license number visible. Built to make the phone ring, not to win design awards.
3. Done for you, while you stay on the tools. You did not spend 8,000 hours earning a license to fight with a page builder at midnight. We run the online side; you run the calls at $90 to $150 an hour.

What every unranked month costs you

Take one job type from the rate table. A 40-50 gallon water heater replacement runs $1,400 to $2,400 in DFW per Crown Plumbing's published range, call it $1,900 in the middle. The companies on page one of Google are booking those every week. If the map pack sends them just 10 water heaters a month that never see your number, that is $19,000 a month in top-line work, $228,000 a year, going to shops whose only edge is that they fixed their visibility before you did.

No countdown timer, no fake deadline. Just the math: licensing took you 6 years, and ranking takes months, so every month you wait moves the payoff back another month while page one keeps cashing your calls.

The license took you 6 years. The site takes days. Get started: https://getonthemap.sbs/start
