Who We Are

Licensed Water Line Repair Professionals Serving San Lorenzo, CA

We started Masters Plumbing Service with a simple belief: plumbing customers in San Lorenzo, CA deserve honest information, upfront pricing, and a technician who actually shows up in the window they promised. That sounds basic. In this industry, it's rarer than it should be.

Our San Lorenzo service hub keeps technicians staged throughout the area so we're not driving 45 minutes to your house while a burst pipe runs unchecked. Fast arrival isn't a slogan for us — it's a logistical commitment backed by how we staff and deploy our crews.

We are fully licensed in CA, carry general liability insurance and workers' compensation coverage on every technician, and we permit work that requires it. That last part matters more than it sounds: an unpermitted plumbing repair can void your homeowner's insurance coverage for related water damage, and it can complicate a home sale. We pull permits, schedule inspections, and close them out correctly.

Warning Signs

When to Stop Waiting and Call a Plumber in San Lorenzo

Your plumbing system tells you when something is wrong. The challenge is recognizing the signals before a small repair becomes a major remediation project.

01

Slow Drains Throughout the House

A single slow drain is usually a localized clog. Multiple slow drains at once signal a main sewer line issue — the kind that backs up into your lowest fixtures if ignored.

02

Water Bill Spike With No Explanation

Hidden supply line leaks in San Lorenzo homes waste thousands of gallons before they surface. A meter check with all fixtures off confirms whether water is escaping.

03

Discolored or Rusty Hot Water

Brown or rust-colored hot water is almost always a water heater with a depleted anode rod or internal corrosion — both signs the unit is approaching failure.

04

Low Water Pressure at Multiple Fixtures

Pressure drops at one fixture point to a clog or a partially closed supply valve. Pressure drops at multiple fixtures simultaneously suggest a main supply problem or significant scale buildup inside supply lines.

05

Running Toilet That Won't Stop

The sound of water running in the tank between flushes is a flapper or fill valve issue. Neither is expensive to fix, but both compound into significant water costs if ignored.

06

Wet Spots or Stains on Ceilings and Walls

Moisture stains on ceilings or walls that reappear after painting point to an active supply or drain line leak inside the structure. The visible damage is usually much smaller than the wet zone inside the wall.

07

Gurgling Sounds in Drains or Toilets

Gurgling when a toilet is flushed, or when the washing machine drains, points to a venting issue or a partial main line blockage. Air displaced by water flow has nowhere to go and creates the gurgling sound.

Leak Detection & Pipe Repair

Hidden Leak Detection in San Lorenzo, CA — Non-Invasive

A water bill that jumped 30% for no visible reason. A ceiling stain that keeps reappearing after painting. A soft spot in flooring with no obvious source. These are hidden leak signatures, and every week one runs undetected is more structural damage and higher water costs. Masters Plumbing Service uses acoustic ground microphones, thermal infrared cameras, and precision pressure decay testing to pinpoint leaks in San Lorenzo homes without speculative wall demolition.

  • Acoustic detection — supply line failures located to within inches under slab or behind wall
  • Thermal infrared camera scanning — moisture mapping without wall cuts
  • Pressure testing — zones isolated to identify the failing branch
  • Slab leak repair — direct access, reroute above slab, or epoxy lining
  • Repipe service — whole-house scope, phased access, pressure-tested final system
Gas Line Services

Gas Line Repair & Installation in San Lorenzo, CA

Gas line work belongs in a short list of plumbing tasks where there is truly no acceptable shortcut. A fitting that isn't fully engaged, a connector bent during installation, or a repair that skips the post-work manometer pressure test can produce a leak that's invisible, odorless (without the added odorant), and dangerous. Masters Plumbing Service's certified gas plumbers in San Lorenzo, CA carry combustible gas detectors to every job and conduct a timed manometer pressure hold test on every repaired or installed segment before restoring gas to the line.

  • Gas leak detection — combustible gas detector at every connection
  • Appliance gas hookup — flex connector, shutoff valve, post-connection pressure test
  • New gas line runs — BTU-load sized, black iron or CSST
  • CSST bonding assessment and installation
  • Pressure test and permit closeout — required documentation provided
Our Process

What to Expect When You Call Masters Plumbing Service in San Lorenzo

This is the sequence every San Lorenzo service call follows. We built it to eliminate the three things customers hate most: waiting, uncertainty, and surprise costs.

1

Live Dispatcher Answers

A real person answers your call, takes your address and describes the situation, classifies urgency, and assigns a technician. You receive a confirmation text with the tech's name and ETA.

2

Licensed Tech Arrives Fast

Our local dispatch model keeps technicians staged throughout San Lorenzo so we're measuring drive time in minutes, not hours.

3

Diagnosis & Flat-Rate Quote

The technician diagnoses the problem — using test equipment, not guesswork — and presents you with a written flat-rate quote before any work begins. You approve the price, then we work.

4

Repair Completed & Warranted

Approved repairs happen immediately — we don't schedule a follow-up for a standard service call. When we leave, the system is functional and the repair carries our written workmanship warranty.

🛡️

Our Workmanship Guarantee — Written, Not Just Verbal

Masters Plumbing Service's guarantee isn't a marketing line — it's a policy. When you get a written receipt from us, the warranty terms are on that receipt. Call us during the coverage period and we'll be back. That's how a local plumbing company that wants to be here in 10 years operates.

Why Masters Plumbing Service

Why San Lorenzo Homeowners Choose Us Over the Competition

These aren't claims — they're policies. Each one represents a specific operational commitment that's either there or it isn't.

⚡

Fastest Local Dispatch

Local staging means when you call at 3 AM in San Lorenzo, the emergency plumber is 12 minutes away, not 55.

📋

Flat-Rate Pricing Always

Every Masters Plumbing Service job in San Lorenzo, CA has a fixed, written price agreed to before work starts. The only time the price changes is if the scope changes — and we tell you that before proceeding.

🔧

Stocked Trucks, One-Visit Fixes

The investment in stocking our trucks is an investment in your time. Most San Lorenzo service calls close on the first visit because the part we need is already on the van.

🪪

Licensed & Verified Every Time

You're not taking our word for it — you can look up every tech's license on the CA licensing board website. We encourage it.

📞

Live Humans Answer the Phone

24/7 live answer means emergency calls reach a decision-maker instantly, not an answering service that relays a message at 8 AM.

🛡️

Written Warranty on Every Job

Verbal warranties mean nothing when a problem comes back. Every Masters Plumbing Service repair and installation in San Lorenzo is backed by a written warranty with specific terms — documented on your receipt.

Business Water Line Repair Solutions Across San Lorenzo, CA

We work with restaurant groups, property management companies, office building owners, hospitality operators, healthcare facilities, and retail properties throughout San Lorenzo, CA. Our commercial team carries the equipment and certifications for commercial-scale plumbing — from 6-inch main sewer service to backflow preventer certification.

Unlike some residential-focused companies that attempt commercial work, Masters Plumbing Service maintains separate commercial crew classifications — technicians who work in commercial kitchens, multi-floor office buildings, and industrial environments regularly, not occasionally. Commercial plumbing has different code requirements, different fixture types, and different service expectations than residential work in CA.

  • Grease interceptor cleaning and health code documentation
  • Backflow preventer testing and annual certification
  • Commercial water heater and boiler service
  • Multi-unit residential plumbing — apartments and condos
  • Emergency commercial response — after-hours priority dispatch
  • Preventive maintenance contracts — scheduled inspection and service

Real Reviews From San Lorenzo Homeowners

Read what San Lorenzo, CA customers say about our response times, our technicians, and our pricing transparency.

★★★★★

"Arrived in 41 minutes on a Sunday night, diagnosed a burst supply line with a thermal camera, made a press-fit repair, and left the water running clean. Price matched the quote exactly."

— D. Okafor, San Lorenzo
San Lorenzo, CA · Emergency Plumbing
★★★★★

"Sewer backed up on a Wednesday evening. I called three companies — two said they couldn't come until Thursday morning, the third quoted me a time-and-material rate with no price cap. Masters Plumbing Service gave me a flat-rate quote over the phone, arrived in 55 minutes, cleared a root intrusion at 38 feet with a cable machine, and ran a camera to confirm the line was clear. Professional from start to finish."

— R. & C. Vásquez, San Lorenzo
San Lorenzo, CA · Sewer Line Service
★★★★★

"Intermittent hot water for weeks before it stopped entirely. The tech traced it to a failing gas control valve, replaced it with a unit from the truck, and tested through a full heat cycle. Done in under an hour."

— B. Harrington, San Lorenzo
San Lorenzo, CA · Water Heater Repair
★★★★★

"Three slow drains throughout the house, plus a gurgling toilet when the washer ran. Masters Plumbing Service's tech accessed the main cleanout, ran a camera, and found root intrusion at two clay tile joints and a partial grease plug at 28 feet. Hydro-jetted the full line, re-scoped to confirm, and the system has performed perfectly for four months. Written service report with the camera footage timestamp is a nice touch."

— F. Okonkwo, San Lorenzo, CA
San Lorenzo, CA · Leak Detection / Drain Service
★★★★★

"We run a restaurant in San Lorenzo. When our grease interceptor backed up at 5 PM on a Saturday — right before the dinner rush — I needed someone fast. Masters Plumbing Service had a commercial tech on-site in under an hour, cleaned the interceptor, cleared the kitchen drain arm, and provided the health code documentation we needed. Saved us a night of revenue. Worth every dollar."

— Property Manager, San Lorenzo
San Lorenzo, CA · Commercial Water Line Repair
★★★★★

"Our gas range had been installed by the previous homeowner with a flexible connector that was kinked almost 90 degrees. I smelled gas faintly near the stove and called Masters Plumbing Service. The tech arrived with a combustible gas detector, confirmed a small leak at the kinked connector, replaced the connector with a properly rated unit, ran a manometer pressure test on the kitchen gas branch, and had the documentation ready for my insurance company. All within two hours of my call."

FAQ

What San Lorenzo Customers Ask Before Calling

Real questions, honest answers. Here's what people in San Lorenzo ask us before scheduling service — and what they should know.

Our emergency response target in San Lorenzo is under 60 minutes, but the realistic range depends on time of day, traffic conditions, and current call volume. We give you an honest ETA at dispatch — not the best-case number that looks good on a website.
Flat-rate pricing means we price the outcome, not the hours. We've invested in technician training and truck stocking so we can work efficiently — and pass that efficiency to customers through competitive flat rates rather than inflating an hourly clock.
We don't have a limited "after-hours menu" — our emergency crews in San Lorenzo carry the same equipment and parts as daytime crews and handle the full scope of plumbing failures at 2 AM the same way we do at 2 PM.
Every technician Masters Plumbing Service dispatches in CA holds an active state plumbing license. Masters Plumbing Service carries general liability insurance and workers' compensation coverage on all field personnel. We can provide license numbers and a certificate of insurance on request — and we encourage you to verify licenses with the CA licensing board before any plumber begins work on your property, regardless of which company you hire.
Yes. Every repair and installation performed by Masters Plumbing Service in San Lorenzo, CA carries a written workmanship warranty — the specific term and scope are documented on your service receipt. Parts warranties from the manufacturer apply in addition to our workmanship coverage. If a covered repair fails within the warranty period, you call us and we return to fix it at no charge.
Our dispatcher will walk you through protective steps for your specific situation when you call. That's part of why we answer live — not just to take your information, but to help you prevent additional damage while our technician drives to you.
The quickest self-check: shut off every fixture and appliance in the house (including ice maker lines and irrigation if connected), then watch your water meter for 15 minutes with nothing running. If the meter dial or leak indicator is moving, water is escaping the supply system somewhere. Other indicators include an unexplained increase in monthly water usage, ceiling stains that recur after painting, soft spots in flooring, mold odor without visible source, or the sound of running water inside walls with all fixtures off.
Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout San Lorenzo, CA. Our commercial team handles restaurant drain and grease trap service, office building fixture repair, multi-unit residential systems, backflow preventer testing and certification, commercial water heater service, and after-hours emergency response for business properties.
Often, yes — if a CCTV camera scope confirms the pipe is a candidate for trenchless CIPP (cured-in-place pipe) lining. Trenchless lining installs a structural epoxy sleeve inside the existing pipe from an access point — no trenching over the pipe run. It's effective for cracked pipes, root-infiltrated joints, and minor deformation as long as the host pipe retains enough structural integrity to hold the liner during the curing process.
Same-day water heater replacement is available in San Lorenzo for the most common residential tank sizes — our trucks carry 40 and 50-gallon gas and electric units. If your unit is gone and you need hot water today, call us.
Plumbing costs in San Lorenzo, CA vary significantly based on the type of repair, pipe material, access conditions, and parts required. Rather than give you a range that's too wide to be useful, Masters Plumbing Service provides a flat-rate quote after on-site diagnosis — before any work starts. That quote is accurate because we've seen the specific failure, not estimated based on a description.
Pulling permits matters beyond legal compliance: an unpermitted plumbing repair can void homeowner's insurance coverage for related water damage and can create title issues when selling the property. We handle permit procurement and inspection coordination as part of the job — permit costs are disclosed in your flat-rate quote.
