A burst pipe at 2 a.m. or a clogged drain mid-dinner — our licensed technicians in Upland 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 Upland 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.
We handle everything from 3/4-inch copper repiping to tankless water heater swaps to high-pressure hydro-jetting on grease-clogged commercial lines. That scope is intentional — it means one call to +1-855-718-1500 gets you a tech qualified for the actual job, not a referral chain that burns your afternoon.
Every tech carries a current CA master or journeyman plumbing license and a full liability bond.
Our Upland dispatch center takes live calls every hour of every day — including holidays.
We stock parts for common Upland pipe configurations directly on every truck — no parts runs, no second appointments.
We quote a fixed price after diagnosing the problem — that number doesn't climb once we start work.
Most plumbing failures in Upland 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 Upland 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 Upland, 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 Upland technicians.
From slab leak detection to full commercial repiping, our Upland-based plumbers bring the right equipment and the right credentials to every job category below.
When water is actively flooding a Upland 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.
Commercial properties in Upland run larger pipe diameters, higher flow rates, and more complex backflow prevention requirements than residential jobs. Our commercial plumbing division carries the equipment and licensing tier needed for restaurants, multi-family buildings, retail centers, and light industrial facilities.
Proper sizing matters. Undersized units run constantly and fail early. We measure the actual hot water demand of your Upland property before recommending replacement capacity.
A drain snake clears soft clogs. Roots, grease buildup, and scale require 4,000 PSI hydro-jetting that scours the pipe wall clean — and a camera inspection confirms the result. Our Upland drain crews run RIDGID SeeSnake camera systems through sewer lines before and after cleaning so you see exactly what was there and what's gone.
Most slab leaks in Upland, 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 Upland 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 Upland 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.

"The acoustic detection approach they used saved us probably $800 in floor tile restoration. They found the leak, patched it, and the tile work was minimal. Couldn't ask for a better outcome on a stressful day."
"Our water heater gave out on a Thursday night — no hot water, family of four. I called Masters Plumbing Service at 8 p.m., they had a tech at the house by 10:15. He confirmed the tank was past replacement age, quoted me the new unit on the spot, and by midnight we had hot water again."
"Finally found a commercial plumber in Upland 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 Upland 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."
"Whole-house repipe on a 50-year-old house. They did it in two days, kept disruption minimal, and the pressure improvement was immediate and significant. License numbers provided before they started — I checked them."
These questions come directly from Upland customers — we pulled them from call logs and review feedback because these are the things people actually want to know before hiring a plumber.
