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.
Every plumber we dispatch in CA holds an active state license, carries liability coverage, and is background-verified before entering your home.
We run dedicated emergency shifts — no re-routing a daytime crew. When you call at 2 AM in Larkspur, 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.
Our trucks stock over 400 SKUs of repair parts. A second trip for parts is a delay you don't need in an active emergency, which is why we invest in pre-stocking every van.
From main line ruptures to gas-assisted water heater failures, our emergency crew in Larkspur, CA handles the full spectrum of after-hours plumbing crises.
Pipe failures in slab, wall, or crawl space locations require thermal cameras and acoustic detection. We trace the break precisely, open only what we must, and restore line pressure before leaving.
Our crew carries PEX, copper, and HDPE fittings for main-line work. We handle the repair and any required municipal inspection scheduling in CA.
Sewage backing into a basement floor drain or toilet is a Category 3 biohazard event. Our emergency team arrives with a trailer-mounted jetter to clear the blockage, then scopes the line with a CCTV camera to determine if root intrusion, offset joints, or collapse caused the event.
A tank that ruptures overnight can dump 40–80 gallons onto a utility room floor. We shut the supply, drain the tank, assess whether the failure was a faulty T&P relief valve, a corroded anode, or a cracked tank shell, and either repair or replace on the spot.
We do not guess at gas leaks. Every repair includes a manometer pressure test and documentation before the gas is restored — required by most jurisdictions and non-negotiable for your safety.
Hard freezes in Larkspur, CA can 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.
No runaround, no hold queues, no "we'll try to get someone out tomorrow." This is how a real emergency response operates.
The moment you describe the situation, our dispatcher is already routing the nearest available emergency plumber in Larkspur toward your location.
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.
You know the full cost before we turn a wrench. Our pricing is the same at 2 PM and 2 AM. The quote covers parts, labor, and any code-required materials.
Approved repairs happen immediately — we don't schedule a follow-up for a crisis job. When we leave, your system is functional and the repair carries our written workmanship warranty.

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.
Holiday weekend, sewer line backed up into our downstairs bathroom. I braced for a "we can't come until Monday" answer. Instead I had a plumber at my door in 52 minutes. He jetted the main line clear and showed me the camera footage of a root intrusion we'll need to address permanently. No upsell pressure — just clear information.
The on-call tech replaced my corroded water heater same-night. He pulled the old unit, verified the flue draft, installed a new 50-gallon with a code-compliant expansion tank, and tested every connection with a combustible gas detector. No rushed work — just thorough, professional installation.

Our emergency response coverage spans Larkspur and the wider Larkspur, CA service area. We maintain staffed dispatch 24 hours a day so no call goes unanswered regardless of zip code.

Masters Plumbing Service operates around the clock in Larkspur, CA. A licensed emergency plumber is available this minute — no hold, no voicemail.
