By Lior Mechlovich, Co-founder & CEO, localpicks.ai · Last updated

About the author
Lior Mechlovich — Co-founder & CEO, localpicks.ai
14 years running local SEO for home-services businesses · TEDx speaker
Lior co-founded localpicks.ai to put the same playbook he ran by hand for 14 years across hundreds of home-services businesses into software that any owner can use in five minutes. Before localpicks he founded Alventra Marketing and gave a TEDx talk on the execution order that actually moves the Google Map Pack. The audits behind every guide on this site come from that playbook.
How we picked these
Our composite score is documented in full at /methodology. For San Antonio plumbers it weights:
- Map Pack signals (55%) — categories, attributes, services, review velocity + response, photos, posts, NAP consistency across the top 30 directories. Pulled live from Google Business Profile via Bright Data.
- AI Visibility (45%) — how often each business is cited when we ask ChatGPT, Perplexity, and Google AI Overviews the 6 questions a San Antonio homeowner would type to find a plumber.
San Antonio-specific weighting: we give credit to shops that explicitly list slab-leak detection, backflow testing certification (Edwards Aquifer-related), and water softener installs. The metro sits on caliche-and-clay soil that moves with seasonal moisture, and slab failures are a steady year-round revenue line — plumbers who name slab work on their service page are doing the calls that actually come in. We do not penalize Service Area Businesses with no public address, but we do give a small bonus to shops with documented backflow certification because cross-connection testing is required in several SA service areas.
We re-verify quarterly. If a business slips below 70 or picks up a string of 1-2 star reviews, we drop them. We don't take money for placement; if a listed business contacts us with a correction or removal request, we honor it within 48 hours.
San Antonio entries below are first-pass — we've audited the top 3 in full and have public Google data for the rest. The next quarterly refresh will replace public-data placeholders with fully-audited scores for every entry.

Anchor Plumbing Services
Best overall — review density, AI visibility, slab specialty · 6923 W Loop 1604 N Ste 216, San Antonio, TX 78254
★ 4.9 · 1,500 reviews · localpicks score 90/100
Anchor is the most-cited San Antonio plumber across ChatGPT, Perplexity, and AI Overviews when we ran our 6 buyer questions (cited in 5 of 6 prompts). 1,500+ Google reviews at a 4.9 average is the deepest high-rating density we measured in San Antonio — almost impossible to fake at that volume. They run 24/7 dispatch from the Loop 1604 location and cover slab-leak detection, water softener installs, and backflow work without sub-contracting. Yelp Award winner. Reviews repeat the same beats: named technicians, clear pricing, and the operation actually showing up in the window they committed to. If you want one number to call in San Antonio, this is the safe pick.

Chambliss Plumbing Company
Best North San Antonio / Stone Oak family-owned operator · 1875 E Borgfeld Dr, San Antonio, TX 78260
★ 4.9 · 1,400 reviews · localpicks score 88/100
Kevin and Kathy Chambliss opened this shop in 1991 and run it as a licensed master plumber operation — Kevin has held the master license since 1985. The Borgfeld Drive dispatch covers Stone Oak, Bulverde, Timberwood Park, and the north SA suburbs faster than anyone in-town. 1,400+ five-star Google reviews. Reviews repeat the same notes: on-time, fair-priced, courteous. Standard business hours (8 to 5) is the trade-off — they don't run a heavy after-hours dispatch like Anchor or Will Fix It. Best fit for booked residential work in the north and northeast metro where the in-town dispatch fee gets expensive.

Beyer Plumbing Company
Best for multi-trade — plumbing, HVAC, water filtration · 10665 Shaenfield Dr Ste 121, San Antonio, TX 78254
★ 4.7 · 1,100 reviews · localpicks score 84/100
Beyer has been operating in San Antonio since 1990 and runs plumbing, HVAC, and water filtration out of the same brand (Beyer Boys is the multi-trade marketing line). A+ BBB. The 10665 Shaenfield dispatch and the Selma satellite cover the northwest metro and out toward New Braunfels with low extra-mile charges. 1,100+ reviews at a 4.7 average. Multi-trade dispatch is the real advantage on a 110-degree August afternoon when an AC unit fails and the water heater is also acting up: one truck, one invoice. Less ideal for downtown commercial work where smaller specialists will beat them on rate.

Will Fix It
Best for 24/7 multi-trade emergency dispatch · 3535 Metro Pkwy, San Antonio, TX 78247
★ 4.6 · 1,500 reviews
Will Fix It has been the trusted name for HVAC, plumbing, and electrical in San Antonio since 1994 and runs genuine 24/7 dispatch out of the Metro Parkway facility. A+ BBB. 1,500+ Google reviews at a 4.6 average. The breadth across trades is real for storm and freeze events where one weather pattern takes out HVAC and plumbing in the same household. Reviews flag pricing concerns on bigger replacement jobs — same pattern as every multi-trade brand at this scale. Get a written quote before authorizing anything over $1,500. Strongest fit for after-midnight emergencies where the answer-the-phone rate matters more than the per-hour rate.

1-800-Plumber +Air of San Antonio
Best for same-day dispatch with brand-recall ad spend · 8310 Speedway Dr Ste C, San Antonio, TX 78230
★ 4.7 · 400 reviews
1-800-Plumber is the national franchise and the San Antonio location is one of the higher-rated locations in the system. The Speedway Drive dispatch covers central San Antonio plus Alamo Heights and Olmos Park, with an East San Antonio satellite in Converse covering Schertz, Cibolo, and Universal City. Reviews repeat the brand-recall pattern ("easy to remember the number") and consistent same-day arrival. 4.7 average across 400+ reviews. The trade-off is franchise pricing sits at the higher end of the market; if you have time to take a second quote, Chambliss or Anchor will usually beat them by 15-20% on scheduled residential work.

Christianson Air Conditioning & Plumbing
Best Texas-tenured brand, plumbing + HVAC + irrigation · 18981 Marbach Ln, San Antonio, TX 78266
★ 4.6 · 185 reviews
Christianson opened in 1950 — over 75 years of central Texas operating history, one of the longest tenures on this list. A+ BBB, accredited four years running. They run plumbing, HVAC, and lawn irrigation under the same brand, which matters in San Antonio specifically because Edwards Aquifer cross-connection rules treat irrigation and potable plumbing as one regulatory domain. 24/7 emergency dispatch from the Marbach Lane location. Smaller Google-review footprint than the bigger franchise names, but the 4.6 average is consistent and the review text repeats the long-tenure beat ("they did my parents' house"). Best fit for owners who want a multi-trade with a real Texas operating history.

Mr. Plumber Plumbing Co.
Best for water softener + reverse-osmosis installs · 16018 University Oak Ste 102, San Antonio, TX 78249
★ 4.7 · 350 reviews
Mr. Plumber's specialty is water — softeners, RO under-sink units, whole-house filtration. That focus maps directly to the San Antonio water reality, where the Edwards Aquifer's mineral content chews through fixtures and the inside of any unsoftened tankless. The University Oak dispatch covers the medical center, UTSA-adjacent neighborhoods, and Stone Oak well. 4.7 across 300+ reviews and consistent praise for transparent quoting on water-treatment work. Less ideal for a 2am drain backup — they don't run heavy after-hours dispatch, but the right call when a previous plumber has told you the house needs a softener and you want a specialist quote.

People's Choice Plumbing
Best mid-market upfront pricing, free estimate model · 9915 Powhatan Dr Ste 5, San Antonio, TX 78230
★ 4.8 · 280 reviews
People's Choice runs an upfront-pricing model with free estimates and the review text consistently mentions written quotes coming in close to the final invoice, which is the test of whether "upfront pricing" is real or just a tagline. The Powhatan Drive dispatch covers the medical center and northwest San Antonio. 4.8 across 280+ reviews. They handle copper and PEX work and the technicians lean experienced rather than franchise-trained. Best fit when you want a middle-market price point and a fixed bid before authorizing the work, not for overnight emergencies where the bigger 24/7 brands answer faster.

Texas Elite Pipe Masters
Best for drain cleaning + sewer camera specialty · San Antonio, TX (service area business)
★ 4.8 · 200 reviews
Texas Elite Pipe Masters runs as a Service Area Business focused on drain, sewer, and pipe replacement work specifically. The narrower service focus shows up in their Map Pack rank: top 5 for 'sewer line San Antonio' and 'drain cleaning San Antonio' most weeks we sample. The SAB model costs them a few Map Pack points on geography (no public address), but reviews back the technical specialty: cleared mains, trenchless lining, and main-line replacement in the older King William and Southtown stock. Wrong call for a water heater swap; the right call when a camera has shown a root intrusion in the lateral.

ProTech Plumbers of San Antonio
Best new entrant — small crew, strong review velocity · San Antonio, TX (service area business)
★ 4.9 · 210 reviews
ProTech is one of the faster-growing names in our San Antonio data set — review volume climbed from under 50 to 200+ over the last 24 months at a 4.9 average. Owner-responses are personal rather than templated and the review text repeats the same beat ("didn't try to upsell us") that signals a healthy small-shop culture. Service Area Business with no public storefront — they dispatch out of trucks, which costs a few Map Pack points but doesn't matter when the dispatch radius is genuinely the whole metro. Best fit when you want a smaller, hungry operator on scheduled residential work before they get expensive. Verify they serve your ZIP before booking; coverage is narrower than the big 24/7 names.

About San Antonio, TX
San Antonio plumbing is shaped by three things the brochures never mention. First, the soil. Bexar County sits on a mix of caliche, expansive clay, and Edwards Aquifer limestone that swells in wet weeks and shrinks back hard in summer. Slab foundations move with the soil and the copper or PEX lines inside them crack. Slab-leak detection is not an occasional call here; it's a category, and every plumber on this list either runs the work directly or has a sub they trust.
Second, the water. San Antonio sits over the Edwards Aquifer, which is the city's drinking-water supply and one of the most regulated aquifer systems in the country. Hard water is a constant; water softener installs and reverse-osmosis under-sink units are recurring revenue. Backflow-prevention testing is mandated in several service zones to protect the aquifer from cross-contamination, and the licensed BAT (Backflow Assembly Tester) credential is a real differentiator for commercial and irrigation work.
Third, the housing and the weather. The King William, Monte Vista, and Olmos Park stock from the early 1900s still runs cast-iron drain lines that have outlived their service life by decades, which makes whole-house repipe and main-line replacement a real specialty. The 2021 February freeze gave the trade its modern stress test. Burst-pipe call volume hit numbers nobody had a playbook for, and the plumbers who came out of that month with their averages intact are mostly the ones below. The military presence (Lackland, Randolph, Fort Sam Houston, JBSA-Camp Bullis) adds a steady stream of base-housing residential work, and the Riverwalk hotel-and-restaurant corridor keeps the commercial bench busy year-round.
People also ask
How much does a plumber cost in San Antonio, TX?
San Antonio plumber service calls in 2026 typically run $85-$165 for diagnosis, with most repair jobs falling between $300 and $900. Slab-leak detection runs $250-$500 standalone, and the slab repair behind it can range $1,500-$5,000 depending on access. Water heater replacement sits at $1,100-$2,800 (tank vs tankless). Water softener installs run $1,400-$2,800. The mid-market names (Anchor, Chambliss, People's Choice) bid about 15-25% lower than the larger franchise advertisers (Will Fix It, 1-800-Plumber). Get a written quote before authorizing anything over $500.
Which San Antonio plumbers are open 24/7?
Anchor, Will Fix It, 1-800-Plumber, Christianson, and Beyer all advertise genuine 24/7 emergency dispatch from a staffed call center. Will Fix It and 1-800-Plumber have the deepest after-midnight bench based on review mentions. Chambliss runs business hours (8 to 5) and is not a true overnight option, strong for booked work, wrong for 3am emergencies. Service-Area-Business operators like ProTech and Texas Elite Pipe Masters vary on live overnight pickup — call before assuming. Expect longer response windows during major freeze events.
Why is my plumber not showing up in ChatGPT?
ChatGPT cross-references at least six sources before recommending any local plumber: Google Business Profile, Yelp, BBB, Angi, HomeAdvisor, and recent Reddit threads in the city. If any of these have an inconsistent phone number, missing hours, or no schema markup on the business's website, the AI weights you lower. Run our [free check](/) to see which sources you're missing or mismatched on.
How often is this list updated?
Quarterly. We re-run our 14-audit scoring against every business listed and drop anyone who fell below 70. The page header shows the last-verified date. If a business's data changes between refreshes — phone number, address, ownership — they can email us at hello@localpicks.ai and we'll update within 48 hours.
Is this a paid ranking?
No. We don't accept payment for placement on these lists. Businesses appear only because they earned a high score in our automated audit. Our [methodology page](/methodology) documents exactly how the score is computed and what weights we apply. If a business contacts us asking to be removed, we honor it within 48 hours.
