Plano Plumbers Checked Against the City's Own Contractor Registry (2026)
Plano actually sits on two different kinds of ground: roughly west of the Tollway the foundation is Austin Chalk, a limestone that holds fairly still, while the eastern half of the city — including most of the neighborhoods around Historic Downtown — is Blackland Prairie clay, the same shrink-swell soil that keeps foundation and slab-leak crews busy across the rest of Collin County. That split means a plumber who's mostly quoting spot repairs in a west-side kitchen may be underprepared for a tunneling job under a 1970s slab on the east side. Plano's Building Inspections Department also publishes an official list of registered plumbing contractors, which gave us a rare chance to check a private ranking against a government source rather than relying only on reviews. Of the five companies below, three appear on that public registry with matching addresses and phone numbers; the other two are Plano-based businesses we verified against their own sites and outside listings.
How we checked these five
We started from the City of Plano Building Inspections Department's published "Registered Plumbing Contractors" list and matched it against each company's own site and at least one outside listing (BBB, Yelp or BuildZoom). Three of the five companies below — Pelayo Plumbing, Legacy Plumbing and Barbosa Plumbing & Air Conditioning — appear on that city record with an address and phone number that match. The other two, Milestone Electric, A/C, & Plumbing and Plano Plumbing & Leak Detection, are Plano-based businesses we verified through their own sites; we noted where a company's registry status could not be confirmed rather than treating it as equivalent.
What we weighed: appearance on the City of Plano contractor registry 35% · years serving Plano specifically 25% · physical Plano address 25% · site and license-number transparency 15%.

Slab leaks are more common on Plano's east side, where the ground is Blackland Prairie clay rather than the more stable Austin Chalk to the west, and repairs there can run $1,500–$15,000 depending on access and tunneling.
Frequently asked questions about plumbers in Plano
Who is the best plumber in Plano, TX?
For 2026, our top pick is Pelayo Plumbing, a family-owned company on Annapolis Ct in Plano whose address and phone number match the City of Plano's own registered-contractor record. Legacy Plumbing and Barbosa Plumbing & Air Conditioning are also strong options, both likewise confirmed against that same city registry.
Why does Plano have two different plumbing problems depending on the side of town?
The western half of Plano, roughly from the Tollway west, sits on Austin Chalk, a limestone that moves relatively little. The eastern half — including the streets around Historic Downtown — is Blackland Prairie clay, which swells and shrinks with moisture and is the main driver of slab leaks and foundation-related plumbing calls in that part of the city.
How much do common plumbing repairs cost in Plano?
Drain clearing, toilet repairs and faucet fixes typically run $125–$450, with a $50–$95 service call fee. Slab leak repairs range from around $1,500 for an accessible spot repair up to $15,000 for extensive tunneling under an east-Plano slab.
How did you verify these five Plano plumbers?
We started with the City of Plano's official registered plumbing contractors list and matched three companies against it by address and phone. The remaining two are Plano-based businesses verified through their own sites; we did not treat unconfirmed registry status as a mark against a company, only as a difference in how it was checked.
