Claim this spot › How we score these plumbers
Rating is the live Google average pulled from each company’s profile. Review volume measures how many customers actually left feedback, ranked against the others on this page. Confidence weighs the rating against that volume, so a high score on a handful of reviews scores lower than the same score backed by thousands. Recency checks whether people are still reviewing the company now, not just years ago. No business can pay to change these numbers.

Serving all of San Antonio
These plumbers operate out of shops near San Pedro Ave, the Northeast Side, and downtown, but all of them cover the wider San Antonio metro, from Stone Oak down to the South Side and out toward Helotes. Searching for a plumber near me in San Antonio will surface most of these same companies.
What to ask before you hire a plumber
- Is the diagnostic or service call fee credited toward the repair if I go with you?
- Do you charge a flat rate or hourly, and can I get that in writing before work starts?
- Are you licensed and insured for this type of work in Texas?
- Is there an extra charge for emergency, weekend, or after-hours calls?
- What’s the warranty on parts and labor for this repair?
- Will the same technician who diagnosed the issue also do the repair?
Frequently asked questions
Are these rankings paid?
No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.
How did you choose these plumbers?
We pulled real Google Business Profile data for plumbers in San Antonio and ranked them by rating, review volume, and how recently customers are still leaving feedback.
How often is this page updated?
We refreshed this list in September 2026 using current Google ratings and review counts.
Why is San Antonio’s water so hard on plumbing?
Several plumbers on this page mention San Antonio’s hard water directly in their marketing, since high mineral content builds up inside pipes and appliances over time, which is why water softener and filtration work comes up so often in local reviews.
Should I always ask for multiple quotes?
For anything beyond a simple repair, yes. Reviewers on this page repeatedly mention comparing quotes across several companies before choosing, and a couple of these plumbers were specifically chosen because their quote came in lower than competitors.
The bottom line
Shafer Services Plus is the safest default, with the deepest review history on this page and a 4.9 average that holds at scale. If your issue can’t wait, Roto-Rooter’s genuine 24/7 coverage makes it the better call at 2am. Either way, ask whether the service call fee applies toward the repair before anyone shows up.
