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. 8 plumbers on the Irving service roster hold licenses we checked in October 2026; 7 are ranked here. One fact stated up front: no Irving 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 Irving 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 Irving plumber ranking that prints the license number and check date behind every name.

How this ranking works
Most “best plumbers in Irving” 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 Irving; (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.

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.
Irving, in numbers
- Population and housing (Irving city): Irving counted an estimated 257,076 people on July 1, 2025 (U.S. Census Bureau QuickFacts V2025), up 0.1% from the April 1, 2020 Census count of 256,684 — a mature, essentially flat-growth inner suburb. The median value of owner-occupied housing units was $315,600 in 2020-2024, and the owner-occupied rate was 38.1% — Irving is a renter-majority city, with median gross rent of $1,619 (2020-2024).
- Schools: there is no single Irving district. Three districts serve Irving addresses — Irving ISD (most of the city) rated C, Coppell ISD (the northern Valley Ranch area) rated A, and Carrollton-Farmers Branch ISD (the western edge) rated B (82) 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): for a city-limits parcel in Dallas County, the worked stack is Dallas County $0.248650 + Parkland Hospital District $0.212000 + Dallas College $0.106575 + City of Irving $0.589100 + the school district — $2.144725 in Irving ISD ($0.988400), $2.142025 in Coppell ISD ($0.985700), and $2.104425 in Carrollton-Farmers Branch ISD ($0.948100), before any special district (Dallas Central Appraisal District TY2026 table). The Dallas County component is subject to a November 3, 2026 voter-approval election; if voters reject it, those totals fall to $2.120725, $2.118025, and $2.080425. Special districts are per-parcel — a parcel inside the Dallas County Utility & Reclamation District (Las Colinas area) adds $0.685657 — and a small Tarrant County sliver of the city carries Tarrant County entities instead, for which no stack is stated here.
- Expansive clay: Irving 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 (USDA NRCS, Texas State Soil profile). Soil varies by lot; verify a specific parcel in USDA Web Soil Survey.
- On this Registry: 8 plumbers serving Irving hold licenses read at the authority in October 2026; the plumber seat is unclaimed.

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 Irving homebuyer know about local taxes and schools?
Three districts serve Irving addresses in TEA’s 2025 ratings — Irving ISD, which covers most of the city, rated C, Coppell ISD in the northern Valley Ranch area rated A, and Carrollton-Farmers Branch ISD on the western edge rated B (82) — so verify the district for a specific address with the district or on TEA’s TXschools.gov. For Tax Year 2026, a city-limits parcel in Dallas County stacks to $2.144725 per $100 in Irving ISD, $2.142025 in Coppell ISD, and $2.104425 in Carrollton-Farmers Branch ISD, before any special district; the Dallas County component is subject to a voter-approval election on November 3, 2026, and if voters reject it those totals fall to $2.120725, $2.118025, and $2.080425.
