Leaky’s Plumbing, Heating & A/C – San Antonio
SameDay responseLeaky’s Plumbing, Heating & A/C - San Antonio is a San Antonio home-services company covering both plumbing and HVAC, with 24/7 availability for emergencies. Its plumbing side handles repairs, sewer and drain work including trenchless replacement, water heaters, water softeners, and whole-home repiping, while the HVAC teams cover AC and furnace service and installation — so one company can handle a burst pipe in January and a dead AC in August. Reviewers describe one-hour emergency response times even in peak season, Sunday service availability, and technicians who wear shoe covers and keep the work area clean. Corey, Ivan, and Marco are named in reviews for professional, communicative work, and customers highlight transparent pricing with cost calculators that help set expectations before the tech arrives. It is built for homeowners who want a single provider for plumbing and comfort systems: families with aging HVAC and plumbing alike, households that need genuine emergency response rather than next-day callbacks, and anyone who values seeing cost ranges before booking. The around-the-clock availability and dual-trade coverage make it a convenient choice for busy households that would rather make one call than coordinate two contractors.

Longoria Plumbing, Drain, Tunneling & Foundation Services
SameDay responseLongoria Plumbing, Drain, Tunneling & Foundation Services is a San Antonio plumbing company whose signature capability is under-slab tunneling — excavating beneath a home's foundation to replace failing sewer and water lines without tearing up interior floors. Around that specialty it offers leak detection, drain cleaning, water heater service, sewer repair, hydrostatic testing, water softening, and foundation repair, making it a one-stop shop for the under-house problems that scare homeowners most. Reviewers describe dedicated tunneling crews, honest pricing, and an owner who is reportedly a phone call away when questions arise. Eli and Paul B. are named in reviews for professional, communicative work, and foundation companies refer customers to Longoria for the plumbing side of foundation projects — a meaningful vote of confidence from tradespeople who see the work up close. It fits homeowners with slab foundations facing the nightmare scenario: a sewer or water line failing beneath the concrete. The tunneling approach preserves flooring and interiors that traditional cut-and-dig methods would destroy, making it especially valuable for homes with tile or hardwood over the slab. For foundation-adjacent plumbing work and hydrostatic testing, the cross-trade referrals suggest a company that other contractors trust with the hard jobs.

Andre’s Pro Plumbing LLC
SameDay responseAndre's Pro Plumbing LLC is a San Antonio plumbing company serving residential and commercial customers, led by owner Andre. Its services cover leak and pipe repair and installation, drain repair, gas line installation, and fixture work including shower and bathtub installation, sink and faucet installation, toilet installation and repair, garbage disposal installation, and water heater installation and repair — a complete fixture-to-pipe offering for homes and businesses. Same-day and emergency appointments are available, and the company backs its work with a one-year workmanship warranty. Reviewers describe methodical leak diagnosis — technicians who trace a leak to its source step by step rather than guessing — and particular skill with older homes, where supply lines and drain layouts rarely match the textbook. Roy and Andre are named in reviews for showing up on time and explaining the fix clearly before starting. It suits owners of older homes and small businesses who want a careful diagnostician on speed dial: landlords with aging rental stock, homeowners chasing a mystery leak, and anyone who values a workmanship warranty behind the repair. The same-day availability and methodical, evidence-based diagnosis make it a strong fit for customers who would rather have the problem found once than patched twice.

1 Affordable Backflow Testing and Plumbing Services
SameDay response1 Affordable Backflow Testing and Plumbing Services is a San Antonio plumbing company whose specialty is right in the name: backflow testing and prevention, backed by a full slate of plumbing and drainage work. It handles drain cleaning, hydrojetting, sewer cleaning, and leak detection, and it answers emergency calls around the clock — a capability reviewers have put to the test, with one describing a sewer backup cleared in under half an hour. The operation is locally owned, and bookings run on transparent, up-front pricing with a satisfaction guarantee. Drain and sewer work is where the company earns most of its mentions. Reviewers describe technicians arriving quickly for emergencies, clearing backups cleanly, and keeping the work site tidy, with techs Ruben and Martin named repeatedly for courteous, professional service. The hydrojetting capability gives it a step beyond basic cable snaking for heavy grease or root intrusion, and backflow testing serves landlords and businesses with compliance requirements as well as homeowners. It fits customers who want a drainage-first plumber rather than a generalist: homes with recurring clogs or aging sewer lines, and properties that need scheduled backflow testing handled by a company that does it every day. The combination of round-the-clock emergency availability, transparency on pricing before work starts, and a crew that reviewers keep calling back by name makes it a dependable pick for urgent drain and sewer trouble.

George Plumbing Co.
SameDay responseGeorge Plumbing Co., Inc. is a San Antonio plumbing company based on Burwood Lane, locally owned and operated with a long history in the greater San Antonio area. Its services cover residential and commercial plumbing repairs, maintenance, and new installations, plus handyman services. Specialties include leak detection, slab leaks, water heaters including tankless models, water softeners and water treatment, drain and sewer work, backflow prevention, SAWS CSI testing, kitchen and bath remodels, and vintage plumbing restoration including wall heaters and floor furnaces. Review themes center on communication and transparency. Technicians present several repair options and pricing, then explain each step of the job — a realtor client notes Duane and Lee joined a conference call to walk her buyers through the choices. Doug and Nick coordinated with Kohler on a toilet warranty issue, and Will and Austin laid out repair-versus-replace options for a water heater with a full system overview afterward. Tyler and Nathan earn praise for punctual, honest work with step-by-step explanations for customers who know nothing about plumbing. Financing is available. George Plumbing fits San Antonio homeowners who want options-first service with financing for larger jobs, and property professionals who need a reliable referral partner. Its weekday 8-to-6 schedule suits planned repairs and projects. For slab leaks and under-foundation work — where cost anxiety runs highest — the record points to a shop that strategizes with the customer rather than dictating.

Reliant Plumbing
SameDay responseReliant Plumbing is a San Antonio plumbing company operating from Fresno Street on the near West Side, with a second tracked location on Whirlwind Drive. Its specialties lean toward advanced pipe work: trenchless pipe repair, sewer line replacements, whole-home repipes, and custom gas line installations, alongside leak detection and repair, water heater replacement, and toilet replacement. Emergency plumbing is a stated core offering, and the company runs 24-hour operations. Reviewers describe technicians who explain both the problem and the solution in clear terms before starting — Steven, Martin, Ruben, and Thomas are named across reviews — and who respect the property during the work. The company offers 0% interest payment plans, a practical feature for large-ticket jobs like repipes and sewer replacements. Its listed service menu also covers drains, sump pumps, camera inspections, fixtures, and water treatment, making it a full-spectrum residential shop. Reliant fits homeowners facing major pipe work — repipes, sewer line replacement, trenchless repair — who want the method explained and financing available. The trenchless specialty matters for properties where digging up yards or slabs is the main fear. For routine leaks and fixture jobs it is fully capable, but its profile reads strongest for customers weighing big, disruptive projects who want options laid out plainly.

1st Call Plumbing & AC
SameDay response1st Call Plumbing & AC is a plumbing, heating, and air conditioning company based in Uptown Central, San Antonio. Its plumbing work covers leak repair, faucet installation, water heater installation and maintenance, garbage disposal service, and toilet installation, while the HVAC side handles AC tune-ups and repair plus heating system installation. Same-day plumbing and HVAC service and annual maintenance plans round out the offering, positioning it as a year-round home-systems company rather than a fix-only shop. Reviewers repeatedly highlight honest second opinions: one customer describes Koby repairing a water heater in under an hour after another company quoted a full replacement at six times the cost. Technicians named across reviews include Josh W., Reuben, Oscar G., Greg, and Brandon A., praised for thorough explanations, punctual arrival, and clean work. Saturday same-day dispatch gets specific mention, with the company reassigning crews rather than delaying jobs when a technician is tied up. 1st Call fits homeowners who want plumbing and climate systems under one roof, especially those wary of upselling — the review record rewards comparison shoppers. Its 7 AM to 7 PM daily schedule covers evenings and weekends for non-overnight needs. For San Antonio households juggling an aging water heater and an AC unit in the same season, the combined trade coverage is the practical draw.
