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 Upland 24 hours a day, every single day.

Emergency plumbing calls are the worst time to gamble on an unknown contractor. Here's what you get every time you dial Masters Plumbing Service in Upland, CA.
Background-checked, uniformed, and licensed — every technician who arrives at your door in Upland meets the same credential standard we'd hold ourselves to as customers.
Our dispatch model prioritizes proximity. Real-time GPS routing means the closest available licensed tech gets assigned to your address, not whoever happens to be free.
After-hours, weekend, and holiday rates are disclosed before work begins. Time-and-material billing that expands as we go is not how Masters Plumbing Service operates in Upland, CA.
Each emergency vehicle carries shutoff valves, pipe couplings, expansion tanks, water heater elements, drain cables, and diagnostic tools. Most Upland emergency calls close on the first visit because the part we need is already on board.
From burst mains to gas-assisted water heater failures, here's what our emergency crew handles around the clock in Upland, CA.
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.
A tank that cracks overnight can dump 40–80 gallons onto a utility room floor. We shut the supply, drain the tank, assess whether the failure was a T&P valve event, a corroded anode, or a cracked tank shell, and either repair or replace on the spot. Our trucks carry 40- and 50-gallon gas and electric units for same-night replacement.
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 CA code.
Every gas repair we perform in Upland, CA is documented with a written pressure test result. Permits are pulled where required; inspection coordination is included.
Freeze events often produce multiple failure points along the same run. We inspect the full exposed section before repressurizing — not just the segment that failed visibly.
No hold queues, no callback queues, no "we'll try to get someone out tomorrow." This is how a real emergency response operates in Upland.
Your call triggers a GPS-assisted routing lookup for the nearest available emergency technician in Upland. Dispatch confirmation and tech ETA go to you by text.
Real-time location tracking means dispatch knows exactly how far out your tech is. We send you live ETA updates so you're not waiting in the dark.
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.
Approved repairs happen immediately — we don't schedule a follow-up for an emergency job. When we leave, the system is functional and the repair carries our written workmanship warranty.

A pipe behind my laundry room wall burst at 11 PM. I expected voicemail. Masters Plumbing Service answered immediately, had a tech at my door in 38 minutes, located the break with a thermal camera, and repaired a failed copper coupling through a 12-inch drywall cut by 1 AM. The invoice matched the quote exactly. This is how emergency service should work.
Sewer backed up on a Friday night before a family event. Masters Plumbing Service dispatched in under an hour, jetted a 30-foot grease-and-root blockage, and scoped the line. Showed me the camera footage, explained the joint offset at 58 feet we need to watch, and left without any pressure to schedule more work. Exactly the transparency I needed.
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.
