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 Castaic 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 Castaic, CA.
Every tech dispatched in CA holds an active state plumbing license and is covered under Masters Plumbing Service's liability insurance. License numbers available on request — and we encourage you to verify them.
We stage emergency crews throughout Castaic 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 Castaic, 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 Castaic, 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.

Sewage backing into a basement floor drain or toilet is a Category 3 biohazard event. Our crew arrives with a trailer-mounted jetter to clear the blockage, then scopes the line with a CCTV camera to determine whether root intrusion, a joint offset, or a collapsed section caused the event — so the same backup doesn't repeat in six weeks.
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.
Smell gas? That's an evacuation-first situation — leave the building, don't operate switches, call your utility from outside. Once the utility confirms the street supply is off, our certified gas plumbers in CA use combustible gas detectors to locate the failure in service lines, appliance connectors, or meter risers, then repair and manometer-test before gas is restored.
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.
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 Castaic: 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.
