Best for Established Track Record: O’Bryan Plumbing Services
O’Bryan Plumbing Services has been operating since approximately 1982, giving it roughly 43 years of continuous operation — longer than any other company on this list. It carries a BBB A+ rating and has been BBB-accredited since March 2012. Licensed through the Texas State Board of Plumbing Examiners, O’Bryan covers the core residential needs Allen homeowners call about most: leak detection, water heater service, sewer and drain work, and general residential plumbing. For residents who weight longevity and institutional credibility heavily, this is the default recommendation.
Best for Complex Jobs (Slab Leaks, Repiping): Pro-Service Plumbing
Pro-Service Plumbing was founded in 1992 and has maintained a BBB A+ rating with accreditation dating back to September 2001 — one of the earliest accreditation dates among Allen-area plumbers. Its service list skews toward technically demanding work: slab leak detection and repair, full-home repiping, tankless water heater installation, and drain cleaning. Homeowners dealing with older pipe systems or a confirmed slab leak will find Pro-Service’s 33-year track record in that specific work meaningful. Licensed through the Texas State Board of Plumbing Examiners.
Best Local Allen-Based Option: AugerPros Plumbing and Drain
AugerPros Plumbing and Drain is headquartered in Allen, TX, which matters when response time is a factor. Founded around 2018, it is the newest company on this list, but it earned BBB A+ accreditation by April 2019 and has maintained it. Its core services — slab leak repair, drain cleaning, water heater replacement, and repiping — cover the most common residential plumbing calls in North Dallas suburbs. For Allen residents who want a plumber whose home base is the same city, AugerPros is the clearest choice.
Best for Master-Plumber Accountability: Jennings Plumbing Services
Jennings Plumbing Services has served Allen since 2003 and operates as a family-owned business. What distinguishes Jennings is a specific, verifiable credential: every job is backed by a Responsible Master Plumber holding Texas license #M-20326. For homeowners who want documented master-level oversight on slab leak repairs, gas line work, sewer line inspection, or fixture installations — not just a licensed plumber on crew — that accountability structure is worth noting. Jennings also handles drain cleaning and sewer line repair.
Best for Gas Lines and Water Softeners: Thorough Plumbing
Thorough Plumbing is based in Allen and holds BBB accreditation since April 2021. Its service list covers water heater repair and replacement (including tankless), sewer cleaning, and water softener installation, but it also carries a gas contracting credential — a meaningful distinction for homeowners who need a plumber to handle gas line work alongside standard plumbing repairs. For a new build, remodel, or home where gas appliance connections and plumbing are being addressed in the same project, Thorough Plumbing’s scope is practical. Licensed through the Texas State Board of Plumbing Examiners.
Best for Collin County Neighbors and Whole-Home Water Quality: Landry Plumbing
Landry Plumbing is a family-owned operation serving Allen and the broader Collin County and North Dallas area. Its service list includes water heater repair and replacement (conventional and tankless), slab leak detection, drain cleaning, sewer line repair, and whole-home water softener installation. The whole-home water softener offering is relevant in North Texas, where hard water is a documented issue. For homeowners in Allen, McKinney, Plano, or nearby communities who want a single plumber for both core plumbing and water quality work, Landry is a practical option.
How to Choose
All six companies on this list are licensed through the Texas State Board of Plumbing Examiners and carry BBB accreditation. The differences that matter most in practice:
- Years in business — O’Bryan (43 years) and Pro-Service (33 years) have the longest documented histories.
- Local base — AugerPros and Thorough Plumbing are both headquartered in Allen.
- Credential specificity — Jennings publishes a named Master Plumber license number, which makes accountability concrete.
- Service scope — Thorough Plumbing adds gas contracting; Landry adds whole-home water softeners; Pro-Service has the deepest documented experience with slab leaks and repiping.
For most standard residential calls in Allen — a water heater replacement, a slow drain, or a suspected leak — any of these six will meet the baseline. Match your choice to the specific job type and the credentialing factors that matter to your situation.
Frequently Asked Questions
How do I verify a plumber is licensed in Texas?
You can confirm any plumber’s license status through the Texas State Board of Plumbing Examiners (TSBPE) license lookup at tsbpe.texas.gov. A valid Texas plumbing license is required by state law for any plumbing work, and the TSBPE database is publicly searchable by name or license number.
What should I do if I have a slab leak in Allen, TX?
Turn off your main water supply to stop ongoing water loss and call a licensed plumber who specifically lists slab leak detection as a service. Pro-Service Plumbing, AugerPros, and Jennings Plumbing Services all have documented experience with slab leak work in the Allen area.
Are Allen plumbers required to be licensed for water heater replacement?
Yes — in Texas, water heater replacement is classified as plumbing work and must be performed by a licensed plumber under the Texas State Board of Plumbing Examiners rules. A permit is also typically required for water heater replacements in Allen under the City of Allen’s building codes.
Is hard water a problem in Allen, TX, and can a plumber help?
Allen draws water from North Texas Municipal Water District sources, and North Texas water is generally considered hard due to elevated mineral content. Licensed plumbers like Landry Plumbing and Thorough Plumbing both offer whole-home water softener installation as a documented service for Allen-area residents.
