Licensed Plumber Professionals Serving Cohasset, MA

We started Masters Plumbing Service with a simple belief: plumbing customers in Cohasset, MA 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.

When you call Masters Plumbing Service for Plumber in Cohasset, 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.

Every Masters Plumbing Service technician working in Cohasset is background-checked before hire, uniformed, and arrives in a marked vehicle. You know who's coming and you can verify their credentials. That's the standard we hold ourselves to — not because it's legally required, but because it's what we'd want if we were the customer.

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 Cohasset homeowners should watch for — and why waiting makes every one of them worse.

01

Slow Drains Throughout the House

When two or more drains run slow simultaneously in your Cohasset home, the blockage is almost always in the main line, not individual fixture traps.

02

Water Bill Spike With No Explanation

A sudden 20–40% increase in your water bill with no change in usage habits often means a supply line leak inside the structure or underground — invisible but actively running.

03

Discolored or Rusty Hot Water

Rusty hot water in Cohasset, 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

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

A toilet that runs constantly wastes 26–200 gallons per day depending on severity. That's $15–$100 per month per toilet — for a repair that typically costs far less than one billing cycle of waste.

06

Wet Spots or Stains on Ceilings and Walls

Active in-wall leaks in Cohasset, 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

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 Cohasset, MA — 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 Cohasset homes without speculative wall demolition.

  • Acoustic detection — supply line failures located to within inches under slab or behind wall
  • Thermal imaging — moisture zone identification before any demo begins
  • 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

Certified Gas Plumbing in Cohasset

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 Cohasset, 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 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 service — bonding conductor installation per current code
  • Manometer pressure testing and permit documentation

What Cohasset, MA Customers Say About Masters Plumbing Service

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

★★★★★

"Called Masters Plumbing Service at 1:30 AM — burst pipe, water spreading across the kitchen floor. I expected to wait until morning or pay triple time. The dispatcher was calm, professional, and had someone at my door in under 50 minutes. Repair was completed by 3 AM, the tech left the area dry, and I had hot water by breakfast. Exceptional emergency service."

— D. Okafor, Cohasset
Cohasset, MA · 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."

— A. Petrov, Cohasset, MA

★★★★★

"Gas water heater out on Friday evening — tech arrived Saturday morning, diagnosed a failed thermocouple in 10 minutes, replaced it in under 45 minutes total. Price was $175, exactly as quoted."

— S. Nakamura, Cohasset
Cohasset, MA · 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."

— L. & G. Abramowitz, Cohasset
Cohasset, 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."

— Property Manager, Cohasset
Cohasset, MA · Commercial Plumber
★★★★★

"Faint gas smell in the utility room. Tech ran the detector over every fitting, found a micro-leak at a union fitting that had vibrated loose over years of furnace cycling. Repaired, detector-tested every connection, manometer documented."

What Cohasset Customers Ask Before Calling

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

For emergency calls in Cohasset, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout Cohasset — 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.
Yes — every time, without exception. Our technicians in Cohasset, MA present a written flat-rate quote after diagnosing the problem and before beginning any repair work. You review the quote, ask questions, and decide whether to proceed. The price you approve is the price you pay — we don't add labor time or material markups after the fact.
We don't have a limited "after-hours menu" — our emergency crews in Cohasset 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.
Yes. Every repair and installation performed by Masters Plumbing Service in Cohasset, MA 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.
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.
Commercial plumbing service in Cohasset, MA operates under the same 24/7 dispatch model as our residential service. We understand that a plumbing failure at a restaurant or retail property has immediate revenue implications, and we respond accordingly.
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 Cohasset 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 Cohasset, 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.
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.
