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

How this ranking works
Most “best plumbers in Allen” 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 Allen; (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.
Allen, in numbers
- Population and housing: Allen counted an estimated 113,447 people on July 1, 2025, up 8.4% from 104,627 at the April 1, 2020 Census (U.S. Census Bureau QuickFacts, Allen city, Texas, V2025). Median value of owner-occupied housing units, 2020-2024: $464,100; owner-occupied rate 69.4%; median household income $130,901; 37,243 households.
- Schools: three districts serve addresses inside the Allen city limits. Allen ISD covers most of the city and earned an A in the Texas Education Agency’s 2025 accountability ratings; Plano ISD serves a southwestern portion and earned a B; Lovejoy ISD serves a northern portion (its TEA 2025 letter is not carried in the Registry’s fact build). District boundaries do not follow city limits — verify the district and campuses for a specific address with the applicable district or the Collin Central Appraisal District.
- Taxes: no single consolidated rate exists for Allen — the total depends on the parcel’s school district. Worked example, tax year 2026, for a Collin County parcel in Allen ISD: Allen ISD $1.1037 (M&O $0.7137 + I&S $0.3900) + City of Allen $0.4147 + Collin County $0.151414 + Collin College $0.081220 = $1.751034 per $100 of taxable value, with no MUD. Parcels in the Plano ISD portion substitute Plano ISD’s $1.032750; parcels in the Lovejoy ISD portion substitute $1.237300 per the Collin County Tax Assessor’s 2026 summary table (that total is carried with its rate split unsourced). Public improvement districts bill per-parcel assessments and are never blended into a citywide rate — confirm the entities and rates for a specific parcel with the Collin Central Appraisal District.
- Expansive clay: Allen sits on the Blackland Prairie, where the USDA soil survey for Collin County maps Houston Black clay with shrink-swell potential rated very high and the Texas Water Development Board describes that soil as highly expansive clay that commonly limits building site development — it swells when wet and shrinks when dry, which stresses slab foundations and the under-slab plumbing beneath them. Soil varies by lot; verify a specific parcel in USDA Web Soil Survey.
- On this Registry: 8 plumbers serving Allen hold licenses read at the authority in October 2026; the plumber seat is unclaimed.

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.

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.
