Our top 6 plumbing companies in San Antonio

Each entry explains why the company was selected, what it does well and what to weigh before hiring.

  1. Reliant Plumbing

    licensed 24-hour plumbing plus planned repipes and sewer replacement4.7(813 Google reviews)4848 Whirlwind Dr, San Antonio, TX 78217Best for licensed 24-hour plumbing plus planned repipes and sewer replacement    Rank01

    Why we picked them

    The review volume is what stands out. A 4.7 across 813 reviews is harder to achieve than a perfect five across thirty, and it points to a company doing consistent work at scale in San Antonio. The trade-off is what usually comes with size, so nail down the written scope and the after-hours rate before the truck rolls.

    What we like

    • 4.7 rating from 813 reviews on its Google Business Profile, read September 27, 2026
    • Published hours show cover 24 hours a day, seven days a week
    • Master plumber licence numbers RMP-42389 and M-42389 published on its own site
    • Full range from drain clearing to trenchless sewer replacement and whole-house repipes
    • Commercial and restaurant work listed, including grease traps and mechanical plumbing
    • Trading since 2014 with branches across several Texas metros

    Things to consider

    • The Whirlwind Drive address is listed on its own site as a distribution location, with a separate San Antonio service office on Fresno Street
    • Awards, A+ BBB standing and satisfaction guarantees come from the company's own marketing and are not independently verified here
    • Larger multi-branch operations usually price above independent one-van plumbers on small jobs
    • No published price list, so ask for the after-hours rate and trip charge up front

    Services

    • Emergency plumbing
    • Drain cleaning
    • Water heater repair
    • Leak detection

  2. E L Smith Plumbing

    repair-first plumbing in older inner-loop San Antonio homes4.7(86 Google reviews)2013 West Ave, San Antonio, TX 78201Best for repair-first plumbing in older inner-loop San Antonio homes    Rank02

    Why we picked them

    A small, long-established shop with a licence number published where you can see it and a Google rating of 4.7 from 86 reviews as of September 2026, which is the profile of a firm that keeps its customers rather than chases new ones. The scope listed is wide enough for most household work and stretches into commercial and medical gas piping. Just confirm the emergency call-out charges and the permit arrangement up front, since neither is spelled out publicly.

    What we like

    • Master plumber licence M-8217 published openly on the company website
    • 4.7 rating from 86 reviews on its Google Business Profile, read September 27, 2026
    • Broad scope covering leaks, water heaters, sewer camera inspection, slab leaks and full room fit-outs
    • Company states it has served San Antonio since 1948, with a tight inner-loop service area
    • Says it quotes from a written pricing guide before starting work
    • Weekend hours listed as open 24 hours, with an emergency option on the phone recording

    Things to consider

    • Emergency and weekend call-out pricing is not published, so ask when you phone
    • Email enquiries are only read during weekday office hours, so urgent jobs need a call
    • Service area is focused on San Antonio and nearby suburbs rather than the wider county
    • 86 reviews is a modest count next to the largest local operators

    Services

    • Fixture installation

  3. AAA AUGER Plumbing Services

    after-hours emergencies and slab or sewer line diagnostics in San Antonio4.6(763 Google reviews)450 Pinn Rd, San Antonio, TX 78227Best for after-hours emergencies and slab or sewer line diagnostics in San Antonio    Rank03

    Why we picked them

    A 4.6 average across 763 Google reviews, read on September 27, 2026, is the kind of record that comes from doing a lot of jobs over a long period rather than a good month. The no-surcharge, no-dispatch-fee pitch is the most useful thing here for anyone with a midnight problem, and it is worth confirming on the phone before the truck rolls. Expect a branch operation rather than a familiar face, and price the sewer and slab leak work on the diagnostic detail included, not the headline number.

    What we like

    • Published hours cover 24 hours a day, every day of the week
    • 4.6 from 763 reviews on its Google Business Profile, read September 27, 2026
    • Company says it charges no dispatch fee and no night, weekend or holiday surcharge
    • Costs presented for approval before work starts
    • Range covers drains, sewers, gas lines, leak detection, water heaters and commercial work
    • Part of a multi-city Texas operation with depth of crew and equipment

    Things to consider

    • Licence, insurance and guarantee claims come from the company's own site and are worth verifying directly
    • As a branch of a larger operation, you may not see the same plumber on repeat visits
    • No pricing is published, so get the written quote before any work begins

  4. Premier PROS Plumbing & HVAC

    homeowners who want one company for both plumbing and AC, including after hours4.9(626 Google reviews)2511 S WW White Rd #102, San Antonio, TX 78222Best for homeowners who want one company for both plumbing and AC, including after hours    Rank04

    Why we picked them

    The dual-trade setup is the real selling point here, and 626 reviews at 4.9 suggests the execution holds up across both sides of the business. We would still press on the licence numbers, since the ones displayed on the website look like sample text, and get the after-hours fee stated plainly before booking a 2am call.

    What we like

    • 4.9 rating from 626 Google reviews, read September 27, 2026, a large sample for a firm founded in 2016
    • Genuine 24/7 published hours, useful for freeze events and August AC failures
    • Plumbing and HVAC under one roof, plus a remodeling arm for bathroom and kitchen work
    • Full range of sewer work listed, including camera inspection and trenchless repair
    • Water softening and filtration offered, which matters given local water hardness
    • Maintenance plan covers bi-annual HVAC tune-ups and an annual plumbing inspection

    Things to consider

    • Licence numbers shown on the website look like placeholder text, so verify real numbers on your estimate
    • After-hours and emergency pricing is not published, so ask before dispatch
    • Two phone numbers appear across listings, which can cause confusion when booking
    • Service area stretches well north, so confirm arrival windows if you are past Loop 1604

    Services

    • Drain cleaning
    • Water heater repair
    • Repiping
    • Sewer line repair
    • Leak detection
    • Gas line work

  5. A&A Plumbing, Heating, and Cooling

    homeowners in Schertz and northeast San Antonio who want plumbing and HVAC from one contractor4.9(3739 Google reviews)121 Windy Meadows Dr, Schertz, TX 78154Best for homeowners in Schertz and northeast San Antonio who want plumbing and HVAC from one contractor    Rank05

    Why we picked them

    The review volume is what stands out. Nearly 3,700 Google reviews at 4.9 is a serious body of evidence for a suburban contractor, and the dual plumbing and HVAC menu means one number covers most of what fails in a San Antonio house. Just pin down after-hours pricing and permit responsibility before the truck rolls, particularly on slab and sewer work.

    What we like

    • Google rating of 4.9 from 3,739 reviews as of September 27, 2026, an unusually large review base
    • Texas master plumber licence M37249 published on its own website
    • Plumbing and HVAC under one roof, from hydro jetting to heat pump installation
    • Published hours are 24 hours a day, seven days a week
    • Trading since 2007 according to its website, with slab leak and softener work reflecting local conditions

    Things to consider

    • Two different phone numbers appear across the Google listing and the website
    • After-hours and weekend call-out pricing is not published, so confirm it when booking
    • Financing and maintenance plans suggest a quoted-package model rather than the lowest hourly rate
    • Based in Schertz, so response times may be longer for the far west and south sides of San Antonio

    Services

    • Water heater repair
    • Repiping
    • Leak detection

  6. The Waterboy Plumbing Services San Antonio

    water softener installs and camera-diagnosed sewer line repair in San Antonio homes4.9(71 Google reviews)8407 Bandera Rd Ste 103- Box 410, San Antonio, TX 78250Best for water softener installs and camera-diagnosed sewer line repair in San Antonio homes    Rank06

    Why we picked them

    The combination of water softeners and trenchless sewer work is a sensible pairing for this city, and the camera-first approach to diagnosis is what you want from anyone quoting a line replacement. A 4.9 average across 71 Google reviews suggests the customer experience holds up. Just reconcile the two sets of published hours when you call, and confirm the RMP licence and after-hours pricing before committing.

    What we like

    • 4.9 rating from 71 reviews on its Google Business Profile, read September 27, 2026
    • Genuine specialism in whole-home water softening, which matters in hard-water San Antonio
    • HD sewer camera inspection used to diagnose before recommending a repair
    • Trenchless water and sewer line options that can spare yards and driveways
    • Family-owned with stated flat-rate quoting before work begins
    • After-hours emergency response for burst pipes and sewage backups

    Things to consider

    • Google shows open 24 hours daily while the website lists weekday and Saturday hours with 24/7 emergencies only, so confirm when you call
    • Licence RMP-46364, insurance, experience figures and the guarantee come from the company's own site and should be verified independently
    • Flat-rate pricing means asking upfront what an after-hours or diagnostic fee includes
    • A smaller family shop may not suit very large multi-crew commercial projects

    Services

    • Drain cleaning
    • Repiping
    • Sewer line repair
    • Leak detection

How to choose a plumber in San Antonio

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope
