How we picked
We only list real businesses we could check in public sources: the company's own website, its Better Business Bureau profile, or a third-party review site. Years in business, license numbers and ratings come straight from those sources and are labeled with where we saw them. We don't make up ratings, and we leave a fact out if we couldn't confirm it. Texas plumbers are licensed by the Texas State Board of Plumbing Examiners (TSBPE). You can verify any license on its website. Always get at least 2–3 written quotes, and check insurance and references before you hire. See how to check a Texas contractor's license and our slab leak repair cost guide.
