A burst main, sewage backing up through the floor drain, a water heater flooding your utility room at 2 AM — these don't wait for business hours. Masters Plumbing Service keeps a fully-staffed, truck-loaded emergency crew in San Antonio 24 hours a day, every single day.

These aren't claims — they're specific operational policies that apply to every emergency call we take in San Antonio, TX.
Background-checked, uniformed, and licensed — every technician who arrives at your door in San Antonio meets the same credential standard we'd hold ourselves to as customers.
We stage emergency crews throughout San Antonio on dedicated shifts — not re-routing a daytime plumber who's already running calls. When you dial at 3 AM, the on-duty emergency tech is already in a stocked truck.
Emergency surcharges are built into the flat-rate price upfront — not added to your invoice after the repair is done. You review the written quote, approve it, then we work. What you sign is what you pay.
A "we'll have to order that" on an emergency call isn't acceptable. We stock our trucks specifically to avoid it — 400+ SKUs of the most common emergency repair parts.
These are the calls that can't wait — and the ones our team is trained, certified, and equipped to resolve fast.
A burst pipe — from freezing, corrosion, or sudden pressure spike — releases water fast. Our crew isolates the break at the nearest shutoff, identifies the pipe material (copper, PEX, galvanized), and installs a sweated or press-fit repair rated to local code. Every supply-line repair ends with a pressure test before we leave.

We contain the affected area, clear the restriction, and provide a written scope report with camera findings. If structural repair is needed, we tell you exactly what and why before quoting it.
Tankless unit failures are diagnosed from error codes and component testing — flame rod, flow sensor, heat exchanger — with replacement parts for major brands stocked on our emergency vehicles.
A failed main shutoff or a street-to-meter line leak leaves your property without water or flooding a yard. We coordinate with the local utility for safe shutoff, then excavate minimally, repair the breach, and restore flow — with the permit pulled where required by TX code.
Every gas repair we perform in San Antonio, TX is documented with a written pressure test result. Permits are pulled where required; inspection coordination is included.
Hard freezes trap water in exterior walls and uninsulated crawl spaces. We locate frozen segments with infrared cameras, thaw lines safely using electric heat tape — never open flame — and inspect for splits that formed under ice pressure. If a freeze has already caused a crack, we repair the section and wrap exposed pipe with foam insulation against recurrence.
No hold queues, no callback queues, no "we'll try to get someone out tomorrow." This is how a real emergency response operates in San Antonio.
Your call triggers a GPS-assisted routing lookup for the nearest available emergency technician in San Antonio. Dispatch confirmation and tech ETA go to you by text.
The assigned tech confirms ETA and arrives in a fully-stocked emergency vehicle. Target arrival in San Antonio: 30–60 minutes from dispatch. No side trips to a supply house.
The tech isolates the problem using pressure gauges, thermal cameras, or acoustic listening devices as needed, then presents a written flat-rate quote. No work starts until you approve the price.
We photograph the completed repair, provide a written service summary, and walk you through any precautions before packing up.

Woke up to my basement floor wet. Masters Plumbing Service answered on the first ring, walked me through shutting off the main while the tech drove over, and arrived in under 45 minutes. Press-fit repair on a copper elbow, pressure-tested before leaving. Done by 3 AM.
Holiday weekend sewer backup into our downstairs bathroom. Tech arrived in 52 minutes with a jetter and camera. Cleared the main line, confirmed clear on the scope, noted a root intrusion entry point for future monitoring. Clean, professional, and no runaround.
Water heater cracked at 10 PM. Masters Plumbing Service had a replacement 40-gallon gas unit on the truck, drained and pulled the failed tank, installed the new heater with code-compliant flex connectors and expansion tank, and had hot water restored by midnight. Written warranty on the install. No panic required.
