Emergency plumbing calls are not the moment to gamble on an unknown contractor. Here's what you get every time you dial Masters Plumbing Service.
Our technicians are licensed master and journeyman plumbers in CA — not day-labor handymen. You see ID, license number, and vehicle markings before work begins.
We run dedicated emergency shifts — no re-routing a daytime crew. When you call at 2 AM in Knightsen, the on-duty emergency plumber is already in a stocked truck, not waking up from a sleep.
We quote you a fixed price before touching a wrench — emergency surcharges are factored in upfront, not added to the invoice after the fact. What we quote is what you pay.
Each emergency vehicle carries the parts inventory to handle the most common crisis calls — shutoff valves, pipe sections, expansion tanks, water heater elements, and diagnostic gear — so the fix happens on visit one.
From main line ruptures to gas-assisted water heater failures, our emergency crew in Knightsen, CA handles the full spectrum of after-hours plumbing crises.
A burst pipe — whether from freezing, corrosion, or sudden pressure spike — releases water fast. Our crew isolates the break at the nearest shutoff, cuts out the failed section, and installs a sweated or press-fit repair coupling rated to local code. We document pressure testing before we leave.
Our crew carries PEX, copper, and HDPE fittings for main-line work. We handle the repair and any required municipal inspection scheduling in CA.
We contain the overflow area, clear the restriction, and provide a written scope report noting whether further lining or excavation repair is needed.
Our trucks carry both gas and electric water heater units in the most common residential capacities. If replacement is the right call, we have the unit, we have the permit knowledge, and we execute same night.
Smell gas? That's an evacuation-first scenario. Once the utility has marked the line safe, our certified gas plumbers in CA use combustible gas detectors to pinpoint leak location in service lines, appliance connectors, or meter risers, then make the repair and pressure-test the segment.
If a freeze has already caused a crack or full rupture, we repair the section, wrap exposed pipe in foam insulation, and advise on permanent weather protection to prevent recurrence.
We've stripped out every delay between your distress call and a working plumbing system. Here's exactly what happens the moment you dial.
Your call goes to a live dispatcher — not voicemail, not an after-hours answering service. In under 90 seconds we have your address, the nature of the emergency, and a technician assigned.
The assigned technician confirms ETA via SMS and arrives with a fully-stocked emergency vehicle. No side trips to a supply house — the parts to fix the most common crises are already on board.
Within minutes of arrival the technician has isolated the problem — using pressure gauges, thermal cameras, or acoustic listening devices as needed — and presents you with a written flat-rate quote. No work starts until you sign off.
We photograph the completed repair, provide you with a summary of what failed and what we installed, and walk you through any precautions. You're not left guessing.

A pipe behind my laundry room wall burst around 11 PM on a Tuesday. I called Masters Plumbing Service expecting to leave a voicemail and deal with it in the morning — someone picked up immediately. The tech arrived in 38 minutes, located the break in my supply line with a thermal camera, and had it repaired with a press-fit coupling by 1:30 AM. The price matched the quote exactly.
Our sewer backed up on a Friday night before a family event. The smell alone was enough to panic. Masters Plumbing Service's emergency team showed up with a jetter and a camera, cleared a 30-foot grease-and-root blockage, and scoped the full line. The whole call took less than 2.5 hours from my phone call to cleanup. Unbelievable service.
My water heater tank cracked and was draining onto the utility room floor. Called Masters Plumbing Service at 10 PM — they had a replacement 40-gallon gas unit on the truck. Tech drained the old tank, pulled the failed unit, installed the new heater with new flex connectors and expansion tank per current code, and lit the pilot. Hot water by midnight.
