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 Luis Obispo 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 San Luis Obispo, CA.
Background-checked, uniformed, and licensed — every technician who arrives at your door in San Luis Obispo meets the same credential standard we'd hold ourselves to as customers.
We stage emergency crews throughout San Luis Obispo 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.
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 San Luis Obispo, CA.
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.
From burst mains to gas-assisted water heater failures, here's what our emergency crew handles around the clock in San Luis Obispo, CA.
We don't guess at burst pipe locations. Acoustic listening devices and thermal cameras let us pinpoint the failure before opening unnecessary drywall — protecting your home and limiting the repair footprint.

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 CA code.
Every gas repair we perform in San Luis Obispo, 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.
We've stripped out every delay between your call and a working plumbing system. Here's the exact sequence.
A real person — not voicemail — takes your call, gets your address, classifies the emergency, and assigns the nearest available tech. Under 90 seconds from hello to dispatch.
The assigned tech confirms ETA and arrives in a fully-stocked emergency vehicle. Target arrival in San Luis Obispo: 30–60 minutes from dispatch. No side trips to a supply house.
Emergency calls get the same quote-before-work policy as any scheduled service. The flat rate is the same at 2 AM as it is at 2 PM.
We photograph the completed repair, provide a written service summary, and walk you through any precautions before packing up.

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.
Gas water heater stopped lighting on a Sunday. Tech arrived same day, tested the thermocouple — reading 9mV, well under the 25mV minimum — swapped the thermocouple and pilot assembly in 45 minutes. Exact quoted price. Runs perfectly.
