Ranked by real Google ratings and review volume · How we chose

We compared 20 plumbers in Round Rock on Google Maps · 5 listed · How we rank

A slab leak or a dead water heater doesn't care that every plumber you call sounds friendly. The plumbers in Round Rock on this page hold more than 5,900 Google reviews between them, and every one is rated 4.8 or 4.9, so stars won't settle it. What will: whether the shop is plumbing-only or also sells heating and air, how it handles estimates, and who can actually show up this week.

Short answer: Crow's Plumbing Service has the biggest review base here, rated 4.9 from more than 2,200 Google reviews, with drain, sewer-line and water heater work listed on its site. Kinsey Plumbing, Heating and Air (4.8) suits homes that may need HVAC too, and JustUs Plumbing (4.9) draws steady praise for honest, no-upsell advice. Pricing depends on the job, so get a written estimate before work begins.

How the scores work

Rating is each business’s live Google star average. Review volume is how many customers have rated it, compared across the plumbers on this page. Confidence weighs the rating by that volume, so a 4.8 from over a thousand people carries more weight than a 4.9 from a few dozen. Recency shows how recently customers are still leaving reviews. No business can pay to change these numbers.

What affects plumbing prices in Round Rock

We found no reliable local price list for Round Rock plumbers, so we aren’t printing a cost table. Price mostly follows the job type (a clogged drain versus a sewer line or water heater), how easy the pipes are to reach, and whether the visit is after hours. Some shops list a diagnostic or trip charge and Kinsey advertises a $0 diagnostic fee with repair, so ask how each one prices before you book.

Plumbers near you in Round Rock

Every business on this page lists a Round Rock address, in the 78664, 78665 or 78681 ZIP codes. Several also work beyond the city: Crow’s site says it serves the greater Austin area and its reviews mention Georgetown and Austin jobs, and Kinsey’s site lists Cedar Park, Georgetown, Hutto, Leander and Pflugerville among its service areas. Looking for a plumber near me? Each card shows a phone number and a map link.

Questions to ask before a plumber visits

  • Is there a diagnostic or trip fee, and is it credited toward the repair?
  • Can you give me a written estimate before starting?
  • Is the technician a licensed plumber, and what warranty comes with the work?
  • Do you work weekends, and is there an after-hours charge?
  • If financing is offered, what are the exact terms?
