Both are family-owned, both work Liberty Hill, and both print a licence number. The difference is in the warranty term, the office hours and how long each licence has been held.
OnCall Plumbing is a family-owned Liberty Hill company with an office on Clear Fork Loop and a second one in Austin, and it dates itself to 2010. Vaquero Plumbing is a three-generation family company on Cara Cove, a few minutes away. Both lists cover water heaters, tankless units, drain cleaning, leak repair and gas work. Where they differ is the warranty term each company posts, the office hours, and how long each licence has been held.
Everything below about OnCall Plumbing comes from their own website, read on October 20, 2026, with the Texas State Board of Plumbing Examiners’ public licensee list read the same day. Where their site does not say something, the table says so. Everything about Vaquero Plumbing comes from our own pages and the same state list.
