How to Check a Texas Plumber License Before Work Starts

The costly mistake is checking a plumber's license after the job goes wrong. By then the pipe is in the wall, the money is gone, and the only tool left is a complaint form. Check before anyone cuts a pipe. We wrote this because almost every plumber in our Texas directory works in a border city, and a name on a truck door tells you nothing about the license behind it.

Run the State Search in Four Steps

Texas plumbers are licensed by the Texas State Board of Plumbing Examiners. It runs a free public license search. You do not need an account.

1. Pick the search type. The board offers five. Search by Name, Search by Name for a Specified License Type, Search by License Number, Search by City and Search by County.
2. Start with the license number if you have it. It is on the plumber's card. For a company, it should be on the truck. Numbers do not have spelling problems. Names do.
3. Match three things. The name on the record, the license type, and whether it is current. All three have to fit the person standing in your kitchen.
4. Look up the company's master plumber too. The person on your job may be an apprentice. That is legal. But the company still needs a Responsible Master Plumber, and that license is the one behind your contract.

Want a list instead of one name at a time? The board posts a free licensee list as CSV files that open in any spreadsheet. There are six files. One each for Responsible Master Plumber, Master Plumber, Journeyman Plumber, Tradesman Plumber Limited, Plumber's Apprentice and Plumbing Inspectors. The board says the tables update daily. The Responsible Master Plumber file shows the last known company name for each license. So you can search a company name and see which master plumber stands behind it.

Which Texas Plumbing License Does What

A plumber's card says one of a few things. Each one allows a different kind of work. The board lists four licenses, three endorsements and four registrations on its license types page.

The fees come from the board's pages for the apprentice, the journeyman, the master and the Responsible Master Plumber. The Responsible Master Plumber fee is waived if a master applies during the 90 days before a renewal. Then only the $300 renewal is due.

Endorsements sit on top of a license. The three are Medical Gas Piping Installation, Multipurpose Residential Fire Protection Sprinkler Specialist and Water Supply Protection Specialist. If your job is a fire sprinkler line in a house, look for that endorsement on the record. Registrations for drain cleaning and residential utility work are added to an apprentice registration, so a drain cleaner may hold no full license at all.

The Responsible Master Plumber Rule

This rule decides who you can safely hire. State law says anyone who advertises or offers plumbing has to engage a Responsible Master Plumber to provide it. That is Occupations Code 1301.351.

So the license that matters for your contract is not always the one on the person at your sink. A company can send a journeyman or an apprentice. That is normal. What is not normal is a company with no Responsible Master Plumber at all.

• Read the truck. The board says service vehicles must show the company name and the Responsible Master Plumber's license number. No number on the door is your first question.
• Ask for the insurance. A Responsible Master Plumber must show proof of at least $300,000 in commercial liability coverage. The board keeps its own inbox for insurance certificates, listed on its contact page.
• Ask to see the card. Section 1301.351 also says license and registration holders must carry the card on them while they do plumbing. A plumber who cannot show one on the job is breaking a rule before the work even starts.

Old Advice That Stuck

The old line is "just ask if they are licensed." A yes costs nothing to say. It also skips the two facts that matter in Texas.

First, the person at your house may hold an apprentice registration. That is not a license to work alone. An apprentice needs a licensed plumber on the job site the whole time they do plumbing. If the apprentice shows up alone with a wrench, ask where the licensed plumber is.

Second, the license behind your contract belongs to the Responsible Master Plumber. Checking only the worker misses it. Check both names. It takes two searches instead of one.

The other stale tip is "a business license proves it." A registered company name says a business exists. It says nothing about plumbing. Only the board's record does that.

When Texas Does Not Require a License

There are real exceptions, and they are narrower than people think.

• Your own homestead. A property owner does not need a license to do plumbing in his or her homestead, under section 1301.051. This covers you. It does not cover the friend or handyman you pay.
• Some rural and small town property. Section 1301.052 lifts the license rule for property outside a city with no public water, for property outside a city on a water system that does not require a license, for some tracts that do not have to be platted, and inside towns under 5,000 people in counties under 50,000 that pass an ordinance allowing it.
• Not for new work. That same section keeps the license rule for plumbing done with new construction, repair or remodeling. A new bathroom on a ranch still needs a licensed plumber.

Even when the state allows unlicensed work, your city or county may still want a permit and an inspection. Call the permit office before the walls close.

If the Search Comes Up Empty

Try the other search types first. A married name, a nickname or a typo can hide a real record. Search the license number from the card, then the city. If nothing matches, do not let the work start.

Unlicensed plumbing is a crime in Texas. Doing work that needs a license without one, or hiring someone who lacks one, is a Class C misdemeanor under section 1301.508. The board can also add an administrative penalty on top of that, under section 1301.701.

To report it, use the board's General Complaint Form, linked from its contact page, or call the enforcement line at (512) 936-5249. The main office line is (512) 936-5200, open weekdays. Keep the truck photo, the card photo, the invoice and any texts. They are what a complaint runs on.

Where the Plumbers in This Directory Work

A count of the 50 plumbing listings live in this directory when this was written shows how local the trade is. 46 of the 50 sit in El Paso, Laredo or the Rio Grande Valley. El Paso has 13. Laredo and McAllen have 8 each. Mission has 5.

17 of the 50 also list a second trade, and 14 of those are air conditioning or electrical work. That matters for you. Those trades are licensed by a different state agency, not the plumbing board. A shop that fixes your drain and your A/C needs to pass two checks, one for each trade.

Browse the plumbers in the directory, or start with El Paso or McAllen. Then run the state search on any name before you book.
