What Most Plumbers Job Listings Don't Tell You
General overview for this role type; specifics vary by employer.
Plumbing is a licensed trade in Texas. You start as a registered apprentice, log paid on-the-job hours, and work under a licensed plumber before you can sit for the tradesman or journeyman exam. Many job posts list a title like plumber but expect a specific license tier, so read the fine print. Pay is usually hourly for apprentices and shifts toward flat-rate or commission on the service side, where a share of each ticket rewards speed and upselling.
New hires are often surprised by the truck and on-call reality. Service plumbers frequently drive a stocked company van, run a rotating after-hours or weekend shift, and handle emergency calls for burst lines and backups. New-construction and commercial work runs steadier daytime hours but leans on rough-in speed and blueprint reading. Houston humidity, slab foundations, and older cast-iron systems mean steady demand year round, with spikes after freezes and heavy storms.
What to Expect Day-to-Day
General overview for this role type; specifics vary by employer.
A service day starts with a dispatch list and a stocked truck. You confirm parts, plan a route, and roll to the first call. Typical work includes clearing drains, swapping water heaters, fixing leaks under slabs, repairing fixtures, and running camera inspections on sewer lines. You diagnose the problem, quote the repair, and get sign-off before turning a wrench.
Customer interaction is a big part of the role. You explain options in plain language, protect floors and finishes, and leave the work area clean. Paperwork follows every job. You log parts, take photos, and close out the ticket in the field. New-construction plumbers spend more of the day on rough-in, setting drain and vent lines to code, then return for the finish stage to set fixtures. Either path involves lifting, crawling into tight spaces, and coordinating with inspectors so the job passes the first time.

Becoming a Licensed Plumber in Texas
Plumbing is licensed by the Texas State Board of Plumbing Examiners. You register as an apprentice, then work under a licensed plumber while you log paid hours. After enough hours you can test for tradesman or journeyman, and with more experience you sit for the master plumber exam. Backflow and medical gas are separate endorsements that add earning power. Each step requires documented hours and a passing exam, so keeping careful records of your time matters. Texas recognizes experience from some other states, but you still test here to hold a Texas license.
