The short answer: As of October 28, 2026, Neighborhood Registry has read the license record of every plumber ranked below at Texas State Board of Plumbing Examiners and found each license Active. 7 plumbers on the Katy service roster hold licenses we checked in October 2026; 7 are ranked here. One fact stated up front: no Katy plumber has claimed a Registry profile yet, so every name below sits in the License-Checked tier — licenses verified at the authority, profiles not yet maintained by the pros. The first Katy plumber to claim and verify a profile takes the top tier in the next edition, under the same published rules. Until then, this page is the only Katy plumber ranking that prints the license number and check date behind every name.

How this ranking works
Most “best plumbers in Katy” lists are assembled from advertising placements and review counts copied from other websites. This ranking is assembled from exactly one thing: the license record at the issuing authority, read directly by Neighborhood Registry.
- Eligibility. A plumber is eligible only if we have read their record in the authority’s own system and found the license Active. No one can pay to be listed, apply for a rank, or be added by request.
- Tier A — Verified & Claimed. The license is verified at the authority and the pro has claimed their Registry profile, confirmed their details, and maintains it. Tier A always ranks above Tier B.
- Tier B — License-Checked. We have read the license at the authority and found it Active, but the pro has not yet claimed their profile.
- Order inside a tier is mechanical and published: (1) neighborhood seats held in Katy; (2) most recent authority check; (3) time on the Registry (first-verified date); (4) alphabetical. Every input to every score is printed in the entries above.
- Freshness. Licenses are re-checked weekly and formally re-verified every 12 months. A license that lapses or is suspended removes the pro from this ranking at the next re-check — not at the next edition. This page is re-issued monthly; this is the October 2026 edition, built from checks dated October 2026.
Full method: How We Verify — Every check is written to the public verification ledger.
How to verify a Texas plumber’s license
Use the Texas State Board of Plumbing Examiners license search at tsbpe.texas.gov: search by name, business, or license number and confirm the company operates under a Responsible Master Plumber (RMP). In Texas a plumbing company may only offer plumbing work to the public under an RMP whose license backs the business; the master license number must appear on invoices and advertising.
Katy, in numbers
- Schools: Katy ISD earned a B (88) in TEA’s 2025 accountability ratings — the highest score among Texas’s 10 largest districts, per the district’s release of TEA’s rating. The district spans about 181 square miles across parts of Harris, Fort Bend, and Waller counties and opened its 79th and 80th campuses in fall 2025 (Katy ISD, August 18, 2025).
- Inside the incorporated City of Katy, the district’s own attendance-boundary service zones sampled city addresses to Katy Elementary or Hutsell Elementary, Katy Junior High, and Katy High School (Katy ISD boundary service, point queries October 2026). Greater Katy addresses zone across dozens of campuses — verify a specific address in the district’s School Assignment Map.
- Taxes: the incorporated city sits at the tripoint of Harris, Fort Bend, and Waller counties, and Greater Katy layers MUDs and three county stacks. There is no single consolidated Katy tax rate — the rate for a specific home is a per-parcel question at the county appraisal district (Registry Katy fact build, October 2026).
- On this Registry: 7 plumbers serving Katy hold licenses read at the authority in October 2026; the plumber seat is unclaimed.
Frequently Asked Questions

The top-ranked are Hong Plumbing (TSBPE #36509), Lone Wolf Plumbing LLC (TSBPE #39698), Simply Plumbing & Sewer (TSBPE #38175).

How do I verify a Texas plumber’s license?
Use the Texas State Board of Plumbing Examiners license search at tsbpe.texas.gov: search by name, business, or license number and confirm the company operates under a Responsible Master Plumber (RMP). In Texas a plumbing company may only offer plumbing work to the public under an RMP whose license backs the business; the master license number must appear on invoices and advertising. Neighborhood Registry reads the same record and writes every check to its public verification ledger.
What is a Responsible Master Plumber, and why does it matter in Texas?
Texas plumbing companies may only offer plumbing work to the public under a Responsible Master Plumber (RMP) — a master plumber whose license backs the business and who is responsible for its work. The TSBPE license behind every name on this page was read at the Board and found Active in October 2026. If a company’s invoice or truck shows no master license number, the company has not shown you its RMP.
What should a Katy homebuyer know about local taxes and schools?
Katy ISD earned a B (88) in TEA’s 2025 ratings, the highest among Texas’s 10 largest districts. Greater Katy spans three counties and many MUDs, and there is no single Katy tax rate — the stack for a specific home is a per-parcel lookup at the county appraisal district.
