A burst pipe at 2 a.m. or a clogged drain mid-dinner — our licensed technicians in Nicasio reach your door fast, diagnose on the spot, and fix it right the first time. No surprise invoices, ever.
Masters Plumbing Service started because too many Nicasio residents were getting hit with bait-and-switch pricing from out-of-area contractors. Our founders built this company on one promise: every technician who walks through your door carries their CA plumbing license, a fully stocked service van, and the authority to quote a fixed price on the spot — before touching a single pipe.
Whether your slab is shifting and cracking drain lines, or your aging galvanized supply lines are dropping water pressure to a trickle, our team in Nicasio has seen that exact scenario before and carries the correct parts in the van to address it without a second trip.
All field plumbers hold active CA plumbing credentials and the company carries general liability plus workers' comp.
We keep a rotating on-call crew stationed in Nicasio so average drive time to residential calls stays tight.
Each van leaves our Nicasio yard pre-loaded with copper, PVC, PEX, press fittings, and common repair assemblies so we fix it on the first visit.
We quote a fixed price after diagnosing the problem — that number doesn't climb once we start work.
Most plumbing failures in Nicasio homes give advance warning. The ones that cost homeowners the most are the ones where those signals got ignored for one season too long.
Slow or gurgling drains throughout multiple fixtures — often signals a partial blockage or root intrusion in the main sewer line, not just a single clog.
Noticeably lower water pressure — in Nicasio homes with aging galvanized or copper supply lines, dropping pressure usually means scale buildup or a hidden leak upstream.
Water heater rumbling or popping sounds — sediment has layered on the tank bottom and is reducing efficiency; ignoring it accelerates tank failure.
Sewer odors inside the home — a dried P-trap or a cracked vent pipe is the typical culprit; both need professional inspection before they become a health issue.
Unexplained spike in your water bill — even a small pinhole slab leak wastes thousands of gallons monthly. If your bill jumped without a usage change, call us.
Discolored or foul-tasting tap water — corroded supply pipes or a failing water heater anode rod can introduce rust or sulfur into the line.}
Visible moisture or staining under sinks or along baseboards — even slow seeps rot subfloor material and invite mold growth quickly in humid Nicasio, CA conditions.
Running toilets that won't stop — a worn flapper or fill valve wastes roughly 200 gallons per day and is a 10-minute fix for our Nicasio technicians.
From slab leak detection to full commercial repiping, our Nicasio-based plumbers bring the right equipment and the right credentials to every job category below.
When water is actively flooding a Nicasio home or business, every minute matters. Our emergency crews carry cordless press-fitting tools and flexible braided line assemblies specifically because they allow fast shutoff and rerouting without wall demolition in most cases.
We don't upsell. If your shutoff valve needs replacing, we replace the shutoff valve — we don't pitch a whole-house repipe unless the line inspection actually warrants it.
Grease trap maintenance, backflow preventer testing, and high-capacity water heater installation are recurring service categories for our Nicasio commercial accounts — work that demands a contractor with the right insurance and the right permits.
Proper sizing matters. Undersized units run constantly and fail early. We measure the actual hot water demand of your Nicasio property before recommending replacement capacity.
Slow drains rarely fix themselves. Each week of delay typically means additional root penetration or further grease accumulation, increasing the eventual clearing cost.
Most slab leaks in Nicasio, CA properties involve copper lines that have corroded at a soil contact point. We offer in-slab direct repair, epoxy pipe lining, or full rerouting above the slab, depending on the pipe's overall condition.
These aren't marketing slogans — they're operational commitments our dispatch and field teams are held to on every call.
After our tech diagnoses the problem, you receive a written price on a tablet — fixed, not hourly. That number only changes if the scope changes, and only after we tell you why and you approve.
We maintain van rotations specifically within Nicasio zip codes so that emergency calls don't become two-hour waits.
A licensed plumber in CA has passed both state-code exams and field-hour requirements. That credential means they understand code compliance, permit requirements, and safe working procedures that unlicensed contractors skip.
We document every repair with photos before and after. That documentation protects you if a question ever comes up about what was done and why.
We built our dispatch and repair process specifically to eliminate the three things customers hate most: not knowing when someone is arriving, getting surprised by the invoice, and having to call back because it wasn't fixed right.
A live dispatcher in Nicasio takes your call 24/7, collects the details, and immediately identifies the nearest available qualified tech. No voicemail trees, no callback queues on emergency calls.
Your CA-licensed plumber arrives with diagnostic tools — camera, acoustic sensor, pressure gauge — and completes a full assessment of the actual problem, not a guess based on your description.
Once the diagnosis is done, you receive a written flat-rate price. If you approve, we start. If you don't, you pay nothing for the visit on emergency calls during business hours.
Work is completed with properly rated materials, tested under operating pressure, and photographed before and after. You receive a copy of the job record for your files and warranty reference.

"Had a slab leak under our master bathroom in Nicasio — water was seeping through the grout. Masters Plumbing Service sent a tech the same afternoon. He used an acoustic detector, pinpointed the leak without tearing up the entire floor, and had it repaired in one visit. The quote matched the invoice exactly."
"Called at 9 p.m. on a water heater emergency. Tech showed up, assessed the unit, gave me a flat price for a new 50-gallon install, and had it running before I expected. No upsell, no hassle."
"Finally found a commercial plumber in Nicasio who quotes grease trap work upfront and actually shows up when scheduled. Their service report is detailed enough that I can file it for health inspection records."
"Root intrusion in my Nicasio home's sewer line. They ran the RIDGID camera before and after the jetting so I could see exactly what was removed. That transparency is rare and I appreciated it."
"Called about a burst pipe in the garage on a Saturday morning. The dispatcher told me approximately when the tech would arrive, the tech called 15 minutes before arrival, and the pipe was repaired within 90 minutes of my call. That efficiency during an emergency means everything."
"We had a complete repipe done on a 1972 home in Nicasio — all galvanized replaced with PEX. The crew worked in sections over two days, kept the water off window short each day, and patched the drywall access points cleanly. The water pressure after the job was noticeably better."
