Who We Are

Masters Plumbing Service — Lexington, MA's Local Plumber Experts

Masters Plumbing Service is a licensed, fully insured plumbing service operating across Lexington, MA. Our team consists of master plumbers and apprentices who carry active MA licenses and complete annual code-update training — because the plumbing code changes, and your contractor should know about it.

When you call Masters Plumbing Service for Plumber in Lexington, a live dispatcher — not an answering service — takes your call, determines the urgency, and assigns the nearest available licensed technician to your address. From clogged drains to full sewer line collapses, from a dripping kitchen faucet to a water heater that's flooding your utility room, our crews are trained and equipped to handle it on the first visit in most cases.

We are fully licensed in MA, 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

Don't Ignore These — They Cost More the Longer You Wait

Most plumbing problems give warning signs before they become expensive disasters. Here's what Lexington homeowners should watch for — and why waiting makes every one of them worse.

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 Lexington 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

Rusty hot water in Lexington, MA homes typically means the water heater is past mid-life and the tank lining has begun corroding. Anode rod replacement may buy time; tank inspection tells you how much.

04

Low Water Pressure at Multiple Fixtures

If your Lexington home's water pressure has dropped noticeably across the whole house, the issue is upstream — likely the PRV (pressure reducing valve), the main supply line, or corroded galvanized pipe narrowing the interior.

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

Active in-wall leaks in Lexington, MA homes create conditions for mold growth within 24–48 hours of sustained saturation. Locating and repairing the leak quickly limits both structural damage and remediation scope.

07

Gurgling Sounds in Drains or Toilets

In Lexington, gurgling drains — especially when a different fixture is used — are one of the earliest and most reliable signs of a developing main sewer line blockage.

Here's a look at what our Lexington, MA-licensed plumbers do every day — and why the depth of our service offering means you call one company instead of tracking down three.

Sewer & Drain Systems

Lexington Sewer & Drain Specialists

Sewer line failures are the most consequential plumbing problem a property in Lexington, MA can face — and the most misdiagnosed. A sewer line that clears with a cable but backs up in 6 weeks isn't a clogging problem; it's a structural problem that clearing can't fix. Masters Plumbing Service's sewer crew runs a CCTV camera into every sewer line before recommending any repair so you see exactly what's there — and pay for exactly the repair that solves it.

CCTV pipeline camera inspection — distance-marked recorded footage
Hydro-jet drain clearing — 4,000 PSI nozzle rotating through the full pipe diameter
Root intrusion removal — root cutter followed by camera confirmation
CIPP trenchless pipe lining — no-dig structural repair for qualified pipe sections
Sewer line excavation and replacement — spot repair or full run
Manhole-to-manhole commercial sewer service

Leak Detection & Pipe Repair

Find It Before Opening a Wall — Lexington, MA Leak Specialists

Once located, our pipe repair techs use the method appropriate to the pipe type — press-fit or sweated copper, PEX expansion fittings, galvanized replacement, or slab leak rerouting — and pressure-test every repair before leaving.

Acoustic detection — supply line failures located to within inches under slab or behind wall
Thermal imaging — moisture zone identification before any demo begins
Pressure decay testing — confirms active loss before detection begins
Slab leak solutions — three repair approaches, you choose based on cost and disruption
Repipe service — whole-house scope, phased access, pressure-tested final system

Gas Line Services

MA-Certified Gas Line Work — Safe & Tested

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 Lexington, MA 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 service — detector survey, isolation, repair, documented re-test
Gas appliance connections — range, dryer, fireplace, water heater, generator
New gas installation — outdoor kitchen, generator, pool heater, BBQ
CSST bonding assessment and installation
Manometer pressure testing and permit documentation

Customer Reviews

What Lexington, MA Customers Say About Masters Plumbing Service

Read what Lexington, MA customers say about our response times, our technicians, and our pricing transparency.

★★★★★

"Masters Plumbing Service got here in 41 minutes on a Sunday at 10 PM. My kitchen supply line had burst behind the wall and water was running into the cabinet below. The tech used some kind of listening device to locate the exact failure point, made a 10-inch drywall cut, pressed in a repair fitting, and had the water back on with zero leak in under 90 minutes. The price matched the quote exactly. That's the standard."

— T. Morrison, Lexington

★★★★★

"Sewer backup the night before Thanksgiving. Masters Plumbing Service arrived within the hour, cleared a grease-and-root blockage, scoped after clearing, and explained every finding on camera. Transparent and fast."

— R. & C. Vásquez, Lexington

Lexington, MA · Sewer Line Service

★★★★★

"Water heater stopped producing hot water on a Friday evening. Masters Plumbing Service's tech arrived Saturday morning, diagnosed a failed thermocouple in 10 minutes, had the replacement on the truck, and installed it in under 45 minutes. Total cost was $175 — and he told me the price before touching anything. I've been burned by plumbers who find reasons to inflate the job. This was genuinely refreshing."

— S. Nakamura, Lexington

Lexington, MA · Water Heater Repair

★★★★★

"My water bill jumped from $90 to $160 in one month with no change in usage. Masters Plumbing Service ran a pressure decay test, found a 6% pressure loss on the hot side, deployed the acoustic detector on the slab in the utility room, and located the leak at a copper elbow under the slab — 4.5 feet from the wall. They presented three repair options with pricing, I chose the reroute through the wall framing, and the new line has been zero-issue for five months. The detection appointment saved me from speculative demolition."

— L. & G. Abramowitz, Lexington

Lexington, MA · Leak Detection / Drain Service

★★★★★

"As a property manager overseeing 22 units, I need a plumbing contractor who shows up, does the work correctly, and doesn't pad the bill. Masters Plumbing Service has been our go-to for two years. Response times are consistent, the techs are uniformed and professional, and the flat-rate invoicing makes budgeting predictable. We've never had a warranty callback that wasn't honored immediately."

— Restaurant Owner, Lexington

Lexington, MA · Commercial Plumber

★★★★★

"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

Common Questions About Plumber in Lexington, MA

These are the actual questions our dispatchers and technicians answer every day in Lexington, MA.

For emergency calls in Lexington, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout Lexington — not at a single central shop — which keeps our actual drive times short. Non-emergency scheduled calls are booked in specific time windows so you're not clearing your whole day for a "sometime between 8 AM and 5 PM" appointment.

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 Lexington 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 MA 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 MA licensing board before any plumber begins work on your property, regardless of which company you hire.

We document warranty terms specifically because verbal warranties are unenforceable and lead to disputes. When you get a receipt from Masters Plumbing Service, the warranty terms are on that receipt — not implied, not "of course we'd come back" — actually written down.

For active water leaks: locate your main water shutoff valve (typically at the meter, in the utility room, or under an exterior wall) and close it clockwise until it stops. Move valuables off wet floors. Don't use electrical outlets near standing water. For sewer backups: stop using all drains and toilets immediately — continued use worsens the backup. For gas smells: leave the building, don't operate any switches, and call your utility company's emergency line from outside first.

If the meter test confirms water loss, call us before opening any walls. Our acoustic and thermal detection equipment locates leaks to within inches in most cases — which means a small, targeted access opening instead of a speculative wall demolition.

Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout Lexington, MA. 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.

Cases where excavation is required: fully collapsed pipe sections, severe pipe belly (negative grade that holds sewage), and pipe offset too severe for lining to bridge. We scope before recommending anything and show you the camera footage so you can see which category your pipe falls into.

Masters Plumbing Service handles the full range of water heater services in Lexington, MA: diagnosis and repair for gas and electric tank units (thermocouple, pilot assembly, gas valve, heating elements, thermostats, T&P valve, anode rod); tankless water heater repair including igniter assemblies, flow sensors, heat exchanger descaling, and error code diagnosis; and full replacement for units beyond economic repair, including conversion from tank to tankless where the infrastructure supports it.

Plumbing costs in Lexington, MA 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.

Yes — for work that requires a permit under MA plumbing code and local jurisdiction rules. This typically includes water heater replacement, gas line work, sewer line repair or replacement, and any work involving the building's main supply or drain systems.
