Quick Answer: There are hundreds of plumbing companies operating in Houston, TX. Before hiring any of them, verify their license with the Texas State Board of Plumbing Examiners (TSBPE) at tsbpe.texas.gov. Houston plumbing companies charge $85–$150 per hour for standard residential work. Slab foundations, high humidity, and flood exposure make licensed, experienced Houston plumbers especially important — unlicensed work voids homeowner’s insurance claims in Texas.
What License Should a Houston Plumbing Company Hold?
Texas licenses plumbing at the individual level through the Texas State Board of Plumbing Examiners (TSBPE). Every plumbing company operating in Houston should have at least one licensed master plumber on record — the master plumber is who pulls permits and is legally responsible for the work.
License types you’ll encounter:
- Master Plumber — licensed to operate a plumbing business independently and pull permits
- Journeyman Plumber — licensed to perform work under a master plumber’s supervision
- Tradesman Plumber-Limited — licensed for basic tasks only; not appropriate for complex jobs
To verify: search tsbpe.texas.gov by company name or license number. Confirm the license is Active and not expired or suspended. If a company cannot provide a license number before the job starts, do not hire them.
How to Find a Licensed Plumbing Company in Houston
Step 1: Use a directory filtered to Houston. The Houston metro covers over 670 square miles. A plumbing company based in Katy may not regularly serve The Heights or Pearland. Browse licensed plumbing companies in Houston at PlumberLocator.us — Houston Plumbers.
Step 2: Verify the TSBPE license independently. Don’t rely on a company’s website badge or verbal claim. Run the license number at tsbpe.texas.gov — takes two minutes and shows the license status, expiration, and any disciplinary actions.
Step 3: Get itemized written estimates. Reputable Houston plumbing companies will separate labor and materials in writing. A lump-sum quote with no breakdown is harder to dispute if the final bill differs.
Step 4: Confirm permit requirements upfront. Houston requires permits for sewer line work, water heater replacement, gas line work, and major repiping. A plumbing company that doesn’t mention permits for permitted work is a warning sign.

What Services Do Houston Plumbing Companies Offer?
Licensed plumbing companies in the Houston area routinely handle:
Slab leak detection and repair. Nearly all Houston homes sit on concrete slab foundations. When supply lines corrode beneath the slab — accelerated by Houston’s clay soil and humidity — water migrates under the foundation. Slab leak detection requires specialized electronic listening equipment; only licensed plumbers should attempt this work. Ask whether the company uses acoustic detection or thermal imaging.
Sewer line inspection and repair. Houston’s older neighborhoods have aging clay tile and cast iron sewer laterals prone to root intrusion and joint separation. Camera inspection before buying a home in Houston is standard practice. For sewer inspection details, see what is a sewer camera inspection and what does it cost.
Water heater replacement. Houston’s moderately hard water deposits sediment inside tank water heaters, shortening their life. Houston plumbing companies replace both tank and tankless units — a permit is required.
Flood and storm damage repairs. Houston is one of the most flood-prone major cities in the country. After tropical systems, plumbing companies handle submerged water heaters, waterlogged supply and drain lines, and contaminated fixtures.
Gas line work. Houston’s large percentage of gas-heated homes means gas line inspection and repair is a routine service. A master plumber license is required for gas work in Texas.
Frequently Asked Questions About Houston Plumbing Companies
How many plumbing companies are in Houston?
The Houston metro has hundreds of licensed plumbing companies ranging from solo master plumbers to large multi-truck operations. The density means fast response times are available — but it also means unlicensed operators are common. Always verify the TSBPE license before scheduling.
Does Houston require a permit for sewer line work?
Yes. The City of Houston requires permits for sewer line repair, replacement, and new installation. The permit must be pulled by a licensed master plumber. Work done without a permit creates code violations that must be corrected at the homeowner’s expense before a property can be sold.
What is the difference between a plumbing company and a handyman for plumbing work?
A licensed plumbing company employs or subcontracts licensed plumbers who can legally pull permits and perform any plumbing work in Texas. A handyman is generally limited to minor repairs that do not require permits. For any job involving supply lines, drain lines, gas, sewer, or water heaters, hire a licensed plumbing company — not a handyman.
How do I find an emergency plumbing company in Houston?
Call multiple companies simultaneously — don’t wait for callbacks during an active emergency. Ask for the after-hours rate before committing. For guidance on handling plumbing emergencies, see how to find a 24-hour emergency plumber near you.
