Who We Are

Licensed Water Heater Replacement 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.

Our San Antonio service hub keeps technicians staged throughout the area so we're not driving 45 minutes to your house while a burst pipe runs unchecked. Fast arrival isn't a slogan for us — it's a logistical commitment backed by how we staff and deploy our crews.

We are fully licensed in TX, carry general liability insurance and workers' compensation coverage on every technician, and we permit work that requires it. That last part matters more than it sounds: an unpermitted plumbing repair can void your homeowner's insurance coverage for related water damage, and it can complicate a home sale. We pull permits, schedule inspections, and close them out correctly.

Warning Signs

When to Stop Waiting and Call a Plumber in San Antonio

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

When two or more drains run slow simultaneously in your San Antonio home, the blockage is almost always in the main line, not individual fixture traps.

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

Pressure drops at one fixture point to a clog or a partially closed supply valve. Pressure drops at multiple fixtures simultaneously suggest a main supply problem or significant scale buildup inside supply lines.

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

Gurgling when a toilet is flushed, or when the washing machine drains, points to a venting issue or a partial main line blockage. Air displaced by water flow has nowhere to go and creates the gurgling sound.

Sewer & Drain Systems

Underground Sewer Repair — Camera, Lining & Excavation

Sewer line failures are the most consequential plumbing problem a property in San Antonio, TX can face — and the most misdiagnosed. A sewer line that clears with a cable but backs up in 6 weeks isn't a clogging problem; it's a structural problem that clearing can't fix. Masters Plumbing Service's sewer crew runs a CCTV camera into every sewer line before recommending any repair so you see exactly what's there — and pay for exactly the repair that solves it.

  • Sewer scoping — push-rod camera, written report, footage available
  • Hydro-jet drain clearing — 4,000 PSI nozzle rotating through the full pipe diameter
  • Root intrusion removal — root cutter followed by camera confirmation
  • CIPP trenchless pipe lining — no-dig structural repair for qualified pipe sections
  • Open-cut repair — precise camera-located excavation, code-compliant replacement
  • Manhole-to-manhole commercial sewer service

Once located, our pipe repair techs use the method appropriate to the pipe type — press-fit or sweated copper, PEX expansion fittings, galvanized replacement, or slab leak rerouting — and pressure-test every repair before leaving.

  • Acoustic detection — supply line failures located to within inches under slab or behind wall
  • Thermal infrared camera scanning — moisture mapping without wall cuts
  • Pressure decay testing — confirms active loss before detection begins
  • Slab leak repair — direct access, reroute above slab, or epoxy lining
  • Repipe service — whole-house scope, phased access, pressure-tested final system

Commercial Water Heater Replacement in San Antonio — Minimal Downtime

When plumbing fails at your commercial property in San Antonio, every hour of downtime has a cost. Masters Plumbing Service's commercial plumbing response operates on the same 24/7 schedule as our residential service — because a restaurant's grease line backup at 6 PM on a Friday is just as urgent as a homeowner's burst pipe at midnight.

Unlike some residential-focused companies that attempt commercial work, Masters Plumbing Service maintains separate commercial crew classifications — technicians who work in commercial kitchens, multi-floor office buildings, and industrial environments regularly, not occasionally. Commercial plumbing has different code requirements, different fixture types, and different service expectations than residential work in TX.

  • Grease interceptor cleaning and health code documentation
  • Backflow preventer testing and annual certification
  • Commercial water heater and boiler service
  • Multi-family plumbing service — individual unit and common area systems
  • Emergency commercial response — after-hours priority dispatch
  • Preventive maintenance contracts — scheduled inspection and service

Read what San Antonio, TX customers say about our response times, our technicians, and our pricing transparency.

★★★★★

"Arrived in 41 minutes on a Sunday night, diagnosed a burst supply line with a thermal camera, made a press-fit repair, and left the water running clean. Price matched the quote exactly."

— D. Okafor, San Antonio
San Antonio, TX · Emergency Plumbing
★★★★★

"Had a main sewer line backup on the night before Thanksgiving. Masters Plumbing Service dispatched within the hour, cleared a grease-and-root blockage in the main line, and scoped it with a camera after clearing. The tech explained what he found, showed me the camera footage, and noted a joint offset at 62 feet we should watch. Transparent, fast, and fairly priced."

— R. & C. Vásquez, San Antonio

★★★★★

"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

FAQ

Common Questions About Water Heater Replacement in San Antonio, TX

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

For emergency calls in San Antonio, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout San Antonio — not at a single central shop — which keeps our actual drive times short. Non-emergency scheduled calls are booked in specific time windows so you're not clearing your whole day for a "sometime between 8 AM and 5 PM" appointment.
Flat-rate pricing means we price the outcome, not the hours. We've invested in technician training and truck stocking so we can work efficiently — and pass that efficiency to customers through competitive flat rates rather than inflating an hourly clock.
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.
Our dispatcher will walk you through protective steps for your specific situation when you call. That's part of why we answer live — not just to take your information, but to help you prevent additional damage while our technician drives to you.
The quickest self-check: shut off every fixture and appliance in the house (including ice maker lines and irrigation if connected), then watch your water meter for 15 minutes with nothing running. If the meter dial or leak indicator is moving, water is escaping the supply system somewhere. Other indicators include an unexplained increase in monthly water usage, ceiling stains that recur after painting, soft spots in flooring, mold odor without visible source, or the sound of running water inside walls with all fixtures off.
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.
Cases where excavation is required: fully collapsed pipe sections, severe pipe belly (negative grade that holds sewage), and pipe offset too severe for lining to bridge. We scope before recommending anything and show you the camera footage so you can see which category your pipe falls into.
Same-day water heater replacement is available in San Antonio for the most common residential tank sizes — our trucks carry 40 and 50-gallon gas and electric units. If your unit is gone and you need hot water today, call us.
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.
