Best License-Verified Plumbers in Richardson, Texas (October 2026)

The short answer: As of October 29, 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. 5 plumbers on the Richardson service roster hold licenses we checked in October 2026; 5 are ranked here. One fact stated up front: no Richardson 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 Richardson 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 Richardson plumber ranking that prints the license number and check date behind every name.

How this ranking works

Most “best plumbers in Richardson” 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 Richardson; (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.

Richardson, in numbers

Population and housing (Richardson city): Richardson counted an estimated 118,542 people on July 1, 2025 (U.S. Census Bureau QuickFacts V2025), down 0.8% from the April 1, 2020 Census count of 119,469 — a built-out inner suburb. The median value of owner-occupied housing units was $431,400 in 2020-2024, the highest median value in this Dallas County cluster, and the owner-occupied rate was 50.7% — an almost even owner/renter split, with median gross rent of $1,857 (2020-2024).
Schools: there is no single Richardson district — the district follows the county line. Richardson ISD serves the Dallas County portion and rated C (79), and Plano ISD serves the Collin County portion and rated B in the Texas Education Agency’s 2025 accountability ratings. Verify the district for a specific address with the district or on TEA’s TXschools.gov.
Taxes (Tax Year 2026, per $100 of taxable value): the City of Richardson rate is $0.542180 in both counties. A Dallas County city-limits parcel in Richardson ISD stacks Dallas County $0.248650 + Parkland Hospital District $0.212000 + Dallas College $0.106575 + City of Richardson $0.542180 + Richardson ISD $1.131900 = $2.241305; the Dallas County component is subject to a November 3, 2026 voter-approval election, and if voters reject it that total falls to $2.217305. A Collin County parcel in Plano ISD stacks City of Richardson $0.542180 + Collin County $0.151414 + Collin College $0.081220 + Plano ISD $1.032750 = $1.807564 (Collin stack carried by citation to the Plano fact build) — a county-side spread of $0.433741 across one city limit. Special districts, where they apply, are per-parcel; confirm a specific parcel with its county appraisal district (DCAD or Collin Central Appraisal District).
Expansive clay: Richardson sits on the Blackland Prairie, whose Houston Black clays USDA describes as highly expansive — shrinking and swelling markedly with moisture changes — with very high shrink-swell potential that commonly limits building site development in metropolitan areas; that slab-on-grade movement also stresses under-slab plumbing, in a mature, built-out housing stock (USDA NRCS, Texas State Soil profile). Soil varies by lot; verify a specific parcel in USDA Web Soil Survey.
On this Registry: 5 plumbers serving Richardson hold licenses read at the authority in October 2026; the plumber seat is unclaimed.

How do I verify a Texas plumber’s license?

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.

Richardson’s district follows its county line in TEA’s 2025 ratings — Dallas County addresses are served by Richardson ISD, rated C (79), and Collin County addresses by Plano ISD, rated B — so verify the district, county, and appraisal district for a specific address on TEA’s TXschools.gov. For Tax Year 2026, a Dallas County city-limits parcel in Richardson ISD stacks to $2.241305 per $100, with the Dallas County component subject to the November 3, 2026 voter-approval election (if rejected, the stack is $2.217305), while a Collin County parcel in Plano ISD stacks to $1.807564 per $100 — a $0.433741-per-$100 spread across one city limit.
