Who We Are

Licensed Plumber Professionals Serving San Antonio, TX

Masters Plumbing Service is a licensed, fully insured plumbing service operating across San Antonio, TX. Our team consists of master plumbers and apprentices who carry active TX licenses and complete annual code-update training — because the plumbing code changes, and your contractor should know about it.

When you call Masters Plumbing Service for Plumber in San Antonio, a live dispatcher — not an answering service — takes your call, determines the urgency, and assigns the nearest available licensed technician to your address. From clogged drains to full sewer line collapses, from a dripping kitchen faucet to a water heater that's flooding your utility room, our crews are trained and equipped to handle it on the first visit in most cases.

Every Masters Plumbing Service technician working in San Antonio is background-checked before hire, uniformed, and arrives in a marked vehicle. You know who's coming and you can verify their credentials. That's the standard we hold ourselves to — not because it's legally required, but because it's what we'd want if we were the customer.

Warning Signs

7 Signs You Need a Licensed Plumber in San Antonio, TX

Most plumbing problems give warning signs before they become expensive disasters. Here's what San Antonio homeowners should watch for — and why waiting makes every one of them worse.

01

Slow Drains Throughout the House

A single slow drain is usually a localized clog. Multiple slow drains at once signal a main sewer line issue — the kind that backs up into your lowest fixtures if ignored.

02

Water Bill Spike With No Explanation

A sudden 20–40% increase in your water bill with no change in usage habits often means a supply line leak inside the structure or underground — invisible but actively running.

03

Discolored or Rusty Hot Water

Brown or rust-colored hot water is almost always a water heater with a depleted anode rod or internal corrosion — both signs the unit is approaching failure.

04

Low Water Pressure at Multiple Fixtures

If your San Antonio home's water pressure has dropped noticeably across the whole house, the issue is upstream — likely the PRV (pressure reducing valve), the main supply line, or corroded galvanized pipe narrowing the interior.

05

Running Toilet That Won't Stop

A toilet that runs constantly wastes 26–200 gallons per day depending on severity. That's $15–$100 per month per toilet — for a repair that typically costs far less than one billing cycle of waste.

06

Wet Spots or Stains on Ceilings and Walls

Active in-wall leaks in San Antonio, TX homes create conditions for mold growth within 24–48 hours of sustained saturation. Locating and repairing the leak quickly limits both structural damage and remediation scope.

07

Gurgling Sounds in Drains or Toilets

In San Antonio, gurgling drains — especially when a different fixture is used — are one of the earliest and most reliable signs of a developing main sewer line blockage.

Time-and-material billing rewards slow work. Flat-rate pricing aligns our incentive with yours: finish the job correctly and efficiently. Our rates are priced to be fair, not padded for contingency.

Business Plumber Solutions Across San Antonio, TX

We work with restaurant groups, property management companies, office building owners, hospitality operators, healthcare facilities, and retail properties throughout San Antonio, TX. Our commercial team carries the equipment and certifications for commercial-scale plumbing — from 6-inch main sewer service to backflow preventer certification.

  • Commercial kitchen drain and grease trap service
  • Backflow preventer testing and annual certification
  • Commercial water heating — repair, replacement, and efficiency upgrades
  • Multi-family plumbing service — individual unit and common area systems

Customer Reviews

Plumber Reviews — How We Handle It in San Antonio, TX

These aren't composites or marketing-department narratives. They're what customers in and around San Antonio describe after a Masters Plumbing Service service call.

★★★★★

"1:30 AM call for a burst pipe — they arrived in under 50 minutes, completed the repair by 3 AM, and the invoice matched the upfront quote. No surprises."

— T. Morrison, San Antonio
San Antonio, TX · Emergency Plumbing
★★★★★

"Sewer backup the night before Thanksgiving. Masters Plumbing Service arrived within the hour, cleared a grease-and-root blockage, scoped after clearing, and explained every finding on camera. Transparent and fast."

— A. Petrov, San Antonio, TX
San Antonio, TX · Sewer Line Service
★★★★★

"Water heater stopped producing hot water on a Friday evening. Masters Plumbing Service's tech arrived Saturday morning, diagnosed a failed thermocouple in 10 minutes, had the replacement on the truck, and installed it in under 45 minutes. Total cost was $175 — and he told me the price before touching anything. I've been burned by plumbers who find reasons to inflate the job. This was genuinely refreshing."

— B. Harrington, San Antonio
San Antonio, TX · Water Heater Repair
★★★★★

"My water bill jumped from $90 to $160 in one month with no change in usage. Masters Plumbing Service ran a pressure decay test, found a 6% pressure loss on the hot side, deployed the acoustic detector on the slab in the utility room, and located the leak at a copper elbow under the slab — 4.5 feet from the wall. They presented three repair options with pricing, I chose the reroute through the wall framing, and the new line has been zero-issue for five months. The detection appointment saved me from speculative demolition."

— F. Okonkwo, San Antonio, TX
San Antonio, TX · Leak Detection / Drain Service
★★★★★

"As a property manager overseeing 22 units, I need a plumbing contractor who shows up, does the work correctly, and doesn't pad the bill. Masters Plumbing Service has been our go-to for two years. Response times are consistent, the techs are uniformed and professional, and the flat-rate invoicing makes budgeting predictable. We've never had a warranty callback that wasn't honored immediately."

— Restaurant Owner, San Antonio
San Antonio, TX · Commercial Plumber
★★★★★

"Our gas range had been installed by the previous homeowner with a flexible connector that was kinked almost 90 degrees. I smelled gas faintly near the stove and called Masters Plumbing Service. The tech arrived with a combustible gas detector, confirmed a small leak at the kinked connector, replaced the connector with a properly rated unit, ran a manometer pressure test on the kitchen gas branch, and had the documentation ready for my insurance company. All within two hours of my call."

FAQ

Plumber FAQ — Answers for San Antonio, TX Homeowners

These are the actual questions our dispatchers and technicians answer every day in San Antonio, TX.

Our emergency response target in San Antonio is under 60 minutes, but the realistic range depends on time of day, traffic conditions, and current call volume. We give you an honest ETA at dispatch — not the best-case number that looks good on a website.
Yes — every time, without exception. Our technicians in San Antonio, TX present a written flat-rate quote after diagnosing the problem and before beginning any repair work. You review the quote, ask questions, and decide whether to proceed. The price you approve is the price you pay — we don't add labor time or material markups after the fact.
We don't have a limited "after-hours menu" — our emergency crews in San Antonio carry the same equipment and parts as daytime crews and handle the full scope of plumbing failures at 2 AM the same way we do at 2 PM.
Every technician Masters Plumbing Service dispatches in TX holds an active state plumbing license. Masters Plumbing Service carries general liability insurance and workers' compensation coverage on all field personnel. We can provide license numbers and a certificate of insurance on request — and we encourage you to verify licenses with the TX licensing board before any plumber begins work on your property, regardless of which company you hire.
Yes. Every repair and installation performed by Masters Plumbing Service in San Antonio, TX carries a written workmanship warranty — the specific term and scope are documented on your service receipt. Parts warranties from the manufacturer apply in addition to our workmanship coverage. If a covered repair fails within the warranty period, you call us and we return to fix it at no charge.
For active water leaks: locate your main water shutoff valve (typically at the meter, in the utility room, or under an exterior wall) and close it clockwise until it stops. Move valuables off wet floors. Don't use electrical outlets near standing water. For sewer backups: stop using all drains and toilets immediately — continued use worsens the backup. For gas smells: leave the building, don't operate any switches, and call your utility company's emergency line from outside first.
If the meter test confirms water loss, call us before opening any walls. Our acoustic and thermal detection equipment locates leaks to within inches in most cases — which means a small, targeted access opening instead of a speculative wall demolition.
Commercial plumbing service in San Antonio, TX operates under the same 24/7 dispatch model as our residential service. We understand that a plumbing failure at a restaurant or retail property has immediate revenue implications, and we respond accordingly.
Often, yes — if a CCTV camera scope confirms the pipe is a candidate for trenchless CIPP (cured-in-place pipe) lining. Trenchless lining installs a structural epoxy sleeve inside the existing pipe from an access point — no trenching over the pipe run. It's effective for cracked pipes, root-infiltrated joints, and minor deformation as long as the host pipe retains enough structural integrity to hold the liner during the curing process.
Masters Plumbing Service handles the full range of water heater services in San Antonio, TX: diagnosis and repair for gas and electric tank units (thermocouple, pilot assembly, gas valve, heating elements, thermostats, T&P valve, anode rod); tankless water heater repair including igniter assemblies, flow sensors, heat exchanger descaling, and error code diagnosis; and full replacement for units beyond economic repair, including conversion from tank to tankless where the infrastructure supports it.
Common residential repairs — fill valve replacement, flapper, faucet cartridge, drain clearing — are typically in the $100–$300 range. More complex work like slab leak repair, sewer line lining, or water heater replacement varies by scope and we walk you through the numbers on-site. No work begins until you've approved a written price.
Pulling permits matters beyond legal compliance: an unpermitted plumbing repair can void homeowner's insurance coverage for related water damage and can create title issues when selling the property. We handle permit procurement and inspection coordination as part of the job — permit costs are disclosed in your flat-rate quote.
