Six years and a $25 form put your own name on Texas plumbing contracts

Texas hands out very few trade licenses that come with a legal right attached. There is no state general contractor license here at all: framers, roofers, concrete crews, painters and drywall outfits trade without asking the state for anything. Plumbing runs the other way, and that is the good news on this page rather than the bad.

The Texas State Board of Plumbing Examiners licenses the trade under Occupations Code Ch.1301, and the rung at the top of its ladder, the Responsible Master Plumber, is the credential that lets you contract directly with the public. Not a permit privilege. Not a marketing badge. The legal standing to be the person a homeowner writes the check to.

The ladder is priced in hours you are already working plus classroom hours you can sit at night. The master application fee is $25.

Here is the whole thing end to end: what each rung takes, who has to be standing over you while the hours count, which exam vendor you sit with, and the detail that trips up electricians the month they cross over.

Plumbing has its own board, its own portal and its own calendar

The Texas Department of Licensing and Regulation licenses electricians, air conditioning and refrigeration contractors, elevator work and a long list besides. Plumbing is not on it. TSBPE holds the trade instead, and the separation is real: a different statute (Ch.1301 rather than the electricians' Ch.1305), a different online licensing system, a different exam vendor, a different renewal calendar and a different continuing education requirement.

That matters most to people who work both trades. An electrician holding a TDLR license who registers as a plumber's apprentice ends up with two accounts at two agencies. Two logins, two renewal dates, two sets of continuing education hours, and both sets buy scope you can bill for. A shop carrying both trades carries both calendars, and it carries both scopes of work on the same truck.

Read that as terrain rather than tax. A small board with one statute is a board you can learn end to end in an afternoon, and the reward for learning it is that your hours stop being a guess. Everything below comes off TSBPE's own forms and the board's own pages.

The whole ladder on one screen

Two thousand hours is a working year at forty hours a week with two weeks off. Read the hours column again with that number in your head: two years to tradesman, four to journeyman. Master then asks for a Texas journeyman license held at least two years, so six years of ordinary work is the standard route from a first day on a van to a master license.

The two rungs at the bottom of that table are hours. The two at the top are documents. Once your hours are behind you, the rest of the ladder is filing, and filing is fast.

Register as an apprentice in your first week, not your first year

The apprentice registration is a form, not an exam. You file it, you renew it annually, and you work under supervision.

File it the week you start, and the reason is arithmetic rather than paperwork. Tradesman Plumber-Limited asks for 4,000 hours as a registered apprentice. That phrase is load bearing. The hours the board counts are the hours you worked while the registration was live, so the count starts on the day you file and not on the day you first picked up a wrench.

Two habits make the rest of this page easy. Keep your own running hour total by employer, in writing, updated monthly. And keep the name and license number of the plumber who supervised them. Shops close, supervisors move to Oklahoma, and a signature you want in 2030 is far easier to collect in the month the work happened than five years later.

Tradesman Plumber-Limited is the license you hold while the big clock runs

Tradesman Plumber-Limited sits at 4,000 hours as a registered apprentice, plus 24 hours of board approved classroom, plus the exam.

Twenty four hours is three days, or six evenings. Against two years of hours, the classroom is the small half of the requirement, and it is the half you control completely. Book it early. A candidate who crosses 4,000 hours with the classroom already behind them files in the same week; one who goes looking for a course that month waits for the next course to start.

The rung is worth taking on its own terms. It is a license with your name on it, it changes what a shop can bill for your time, and it is the first point on the ladder where you are a licensed plumber rather than someone working under one. It carries the same annual renewal and the same 6 hours of continuing education as everything above it, so the maintenance habit starts here and does not change again.

Journeyman: 8,000 hours and 48 hours in a classroom

Journeyman Plumber is 8,000 hours worked under a licensed plumber, 48 hours of board approved classroom, and the exam.

Four working years and six full days of instruction. The classroom requirement doubles from the tradesman rung, which is the board telling you plainly that the journeyman exam is a different animal, and the 48 hours are the preparation rather than a box beside it.

The supervision requirement is the part to ask about in an interview. Your hours count when a licensed plumber is supervising them, so a shop with licensed plumbers on staff and a habit of signing hour verifications is building your license alongside your paycheck. A shop without that is paying you the same money while your ladder sits still. Asking the question at the hiring stage tells a good employer exactly what kind of hire you are.

What the exam covers, how the board wants your hours documented, and what a journeyman license lets you sign for are in the Texas journeyman plumber guide.

Master: three doors, and only one of them is the long one

Master Plumber has no hour count of its own on the board's current application. It has a held journeyman license, and there are three ways to qualify. This is straight off TSBPE's Master Plumber Examination Application, revised January 2026.

Door B is the one that gets missed, and it is worth a year of your life. A completed DOL approved training program cuts the journeyman hold from two years to one. If you came up through a registered apprenticeship, find that completion certificate before you assume the two year wait applies to you.

Door C is the one that makes Texas easy to move to. Four years of out-of-state journeyman standing puts you in front of the master exam without starting a Texas hour count from zero, which is worth knowing before you turn down a Texas job on the assumption that your years do not travel.

Two practical details. The application fee is $25. And the master exam is computer based at Pearson VUE, a different vendor from the PSI seats TDLR uses for its electrical exams, so an electrician adding plumbing books with a different company at a different center. Booking the exam while the journeyman hold is still running means the license issues on a filing date rather than a test date. The exam content and how to plan the hold are in the Texas master plumber guide.

The Responsible Master Plumber is the rung that sells

Master makes you qualified. Responsible Master Plumber makes you a business.

The RMP is the designation required to contract directly with the public, and getting it asks for two things: a master plumber license in good standing, and a Certificate of Insurance on file with the board. Occupations Code 1301.552 sets the cover at commercial general liability of at least $300,000 for all claims in a one year period, written by an authorized or eligible surplus lines insurer. Section 1301.3576 puts the timing beyond argument: the certificate has to be on file with the board before you work as an RMP.

Order the insurance before you file. Brokers take days, the filing takes minutes, and the sequence people regret is the other one.

The structural detail worth knowing early is that the RMP designation belongs to a person. Texas issues no plumbing company license, so there is no corporate credential to buy or inherit, and one RMP may act as the RMP of record for one company at a time, with company changes handled as a change of company in the board's Online Licensing System.

That is the whole economics of this trade in one sentence. A plumbing business in Texas trades on a named human being. If that human is you, the company cannot contract with the public without you. If it is someone you employ, their departure is a business event rather than an HR event. The filing, the insurance wording and what changing companies actually involves are in the Responsible Master Plumber guide.

Two boards, two ladders, and the plumbing side is the shorter climb

An electrician crossing over, or a shop that runs both trades, is comparing two ladders built by different agencies under different statutes. Side by side they are not the same climb.

Two rows do the work. The plumbing master rung asks for no hours of its own, while the electrical master rung asks for 12,000, which is two more working years stacked on top of the journeyman count. And plumbing has no company credential to buy, so the value of a plumbing business gathers around whoever holds the RMP, where an electrical contractor license sits on the business itself and can be staffed by hiring a master. One detail on the electrical side has no plumbing equivalent: a journeyman candidate may sit the exam at 7,000 hours, though the license issues at 8,000. The full electrical ladder is in the Texas electrician license guide.

Three endorsements, three price lists

On top of the ladder, the board issues endorsements that add scope: medical gas, multipurpose residential fire protection, and water supply protection specialist.

Each one is a bid another plumber on the same street cannot submit. Medical gas is the entry ticket to hospital, clinic and dental fit-outs, work that runs on schedules and pays on commercial terms. Multipurpose residential fire protection covers the combined domestic and sprinkler systems that residential codes increasingly ask for, which puts a plumber on jobs that would otherwise go to a fire protection contractor. Water supply protection specialist is the backflow and cross-connection scope, which a municipal or commercial building buys on a testing schedule rather than in an emergency.

The point of an endorsement is not the certificate. It is the shape of the invoice on the other side of it.

Six hours a year keeps all of it

Every licensed rung renews annually and carries 6 hours of continuing education. Tradesman, journeyman and master alike.

Six hours a year is one long evening. For comparison across the trades on the same site, TDLR asks electricians for 4 hours a year and air conditioning contractors for 8, one of which has to be Texas law and rules. Plumbing sits between them.

Put the license renewal, the continuing education hours and, if you hold the RMP, the insurance certificate expiry on one reminder. Three dates on one calendar renew comfortably in a single sitting, and that sitting is what keeps the company able to sign contracts straight through the year.

The city signs last, and for a licensed plumber it is short

The state license lets you plumb. The city lets you pull the permit, and the cities that register contractors mostly want to see the state credential you already hold.

Fort Worth's $60 line is the clearest illustration of what a master license is worth in practice. The city holds a named master against a registered company, and swapping which human that is has a price tag. Your license is an entry in a municipal record that a payroll depends on. For which Texas trades are licensed at all, start at do you need a contractor license in Texas, and the city by city detail is in Texas city contractor registration.

Selling direct changes which parts of the Property Code are yours

The RMP designation puts you in privity with the owner, which makes you an original contractor rather than a subcontractor, and the Property Code treats the two differently.

Four things follow, and they favor you.

• On a private job, an owner who receives your written payment request owes payment by day 35. Overdue amounts run 1.5% a month under Tex. Prop. Code Ch.28, those terms cannot be waived in the contract, and after notice you have a statutory right to suspend work.
• The monthly notice regime belongs to subcontractors and suppliers. As original contractor you do not send one, so the notice clock that runs to the 15th day of the third month on commercial work and the second on residential is not yours to miss.
• When a payment lands that covers a sub's work, their share goes out within 7 days, and the same 7 days applies sub to sub below you.
• Your lien affidavit clock runs from completion, termination or abandonment of the contract rather than from your last day on site, filing by the 15th day of the third month after that on residential work and the fourth month on commercial. Send a copy to the owner within 5 days of filing, by any delivery method you like.

Two more dates are worth writing down the day you sign. A suit to foreclose the lien runs 1 year from the last day you could have filed the affidavit, on every project type, and an owner can agree in writing to extend that to 2 years if the agreement is recorded before the first year runs out. And 10% of the contract is statutory retainage the owner holds during the work and for 30 days after completion, which is the 10% that decides whether the job made money.

The one to set up before the job starts is the homestead rule. Tex. Prop. Code s.53.254 asks for a written contract executed before any labor or material is furnished, signed by both spouses if the owner is married, and filed with the county clerk. Get that right and a kitchen repipe is a secured debt. It costs a filing fee, and it is the cheapest security a residential plumber can buy.

Those dates are arithmetic done on a bad day, so count them on the Texas lien deadline calculator rather than on a phone screen at the curb, and get paid in 35 days in Texas has the demand letter that goes with the interest.

What this costs on AEC Stack

Your license dates, your continuing education hours, your insurance certificate, your hour logs, your quotes and your invoices sit in one place, with no monthly subscription. AEC Stack takes 2.5% of each invoice processed through the platform, collected on the payment due date, so the platform gets paid when you do.

The ladder is hours, and hours come from work. Setting the company up around the license starts at start your business, and the Texas plumbing packages going out to bid this week are on find work.
