JP Walsh Plumbing & Heating has been serving homeowners and property managers in Medford and across Middlesex County since 2012. What started as a straightforward commitment to doing honest, reliable plumbing work has grown into one of the area's most trusted names for residential and commercial plumbing service. We know these neighborhoods, we know the pipes that run under these streets, and we show up ready to work. Call us and a real local person picks up. Quick to arrive. Careful with your home. Clean when we leave.
Good plumbing work isn't complicated, it's just done right, and that's the standard we hold every job to. Whether you're a homeowner dealing with a stubborn clog or a property manager coordinating repairs across multiple units, we handle the full range of residential and commercial plumbing work. Drain cleaning and clog removal, leak detection and repair, water heater repair and replacement, toilet and faucet and fixture installation, sewer and main line service, garbage disposal installation, water pressure diagnostics, and more. Our licensed plumbers work cleanly, communicate clearly, and leave the job in better shape than they found it. That means clear communication from the first call to the final test, so you always know what's happening and why. Give us a ring and we'll take it from there.
A clogged drain rarely fixes itself. Whether it's a slow kitchen sink, a backed-up shower, a blocked toilet, or a main drain that's backing up into multiple fixtures, we locate the blockage and clear it the right way. For tougher buildup in drain lines and sewer pipes, we use hydro jetting to cut through grease, scale, and debris that a standard snake won't touch. Main drain cleaning and sewer drain cleaning are among the most common calls we handle, and we come prepared to get the line flowing again on the first visit.
Water leaks cause damage fast, and the ones you can't see cause the most. We use a diagnostic approach to track down hidden pipe leaks, water line leaks, and leaks behind walls or under floors before they become a much larger problem. Once we find the source, we walk you through what we found and what it takes to fix it. Customers get straight answers about the scope of the repair and what it will cost before any work begins.
No hot water is one of the most disruptive plumbing problems a household or commercial property can face. We repair and replace tank and tankless water heaters, and we help you figure out whether a repair makes sense or whether a replacement will serve you better in the long run. Tankless water heater installation is a popular upgrade for homeowners who want consistent hot water and better energy performance. Whatever direction you go, work is performed by licensed plumbers who know the equipment and the local code requirements.
From a leaking faucet that won't stop dripping to a toilet that runs constantly or won't flush properly, these are the everyday plumbing problems that add up fast if you let them go. We handle toilet repair and replacement, faucet repair and installation, sink installation, shower and bathtub fixture work, and garbage disposal installation and repair. If you're remodeling or upgrading fixtures, we can coordinate the rough-in and installation so the finished work looks right and functions the way it should.
Older housing stock throughout Medford and the surrounding Middlesex County communities means aging sewer infrastructure is a real and recurring issue. Clay sewer lines, cast-iron drain stacks, and pipes that have been in the ground for decades are prone to cracking, root intrusion, and buildup that causes slow drains and backups. We handle sewer line cleaning, sewer camera inspection, sewer line repair and replacement, and trenchless sewer repair for situations where digging up the yard isn't the right answer. If you're seeing slow drains in multiple fixtures, gurgling sounds in your pipes, or sewage backing up into a basement drain, that's a main line problem that needs attention now. Experienced plumbers who respect your home are on the job from the first camera run to the final line test. No guesswork. No shortcuts. No bill-day surprises. One call, and a plumber is on the way.
For busy homeowners and property managers, aging pipes are a problem that tends to get ignored until it becomes a crisis. Galvanized steel pipes corrode from the inside out, reducing water pressure and eventually failing. Old copper lines develop pinhole leaks. Lead service lines are a health concern that many Middlesex County properties are working to address. We handle whole-house repiping in copper and PEX, burst pipe repair, broken pipe repair, shutoff valve replacement, and water pressure diagnostics. If your home has chronic low water pressure, recurring leaks, or pipes that are simply past their service life, repiping is often the most cost-effective long-term fix. Transparent pricing with no hidden fees on any plumbing job means you know the full scope and cost before we start. We're one phone call from getting your plumbing right.
Scheduling a plumber shouldn't feel like a project. Here's what to expect when you call us:
Property managers, building owners, restaurant operators, and office and apartment building contacts know that plumbing problems don't wait for a convenient time. We work with commercial clients throughout the area on drain cleaning, leak repair, water heater installation and replacement, fixture installation, and sewer line service. We understand that a plumbing problem in a commercial setting affects tenants, customers, and operations, so we move efficiently and communicate clearly at every step. Straight answers about your pipes and fixtures, no surprises, is how we work with every commercial account. Reach out and we'll start at the source of the leak.
Your time matters, so we keep the plumbing job on schedule, and when something goes wrong after hours, we're still reachable. Burst pipes, no hot water, major leaks, and flooded basements don't follow business hours, and neither do we. We offer 24/7 emergency plumbing response for the situations that can't wait until Monday morning. Same-day service is available for non-emergency calls when your schedule demands it. Whether it's a Saturday afternoon water heater failure or a Sunday morning pipe burst, we answer and we come out. Quick to arrive. Careful with your home. Clean when we leave.
Doing plumbing work right matters, and we'll help you get it right, starting with a clear conversation about what the job involves and what it will cost. Before any work begins, you get a straightforward estimate. If something changes once we're into the job, we tell you immediately and explain why. There are no hidden fees added at the end and no vague line items on the invoice. We believe that pricing should be easy to understand, and we stick to that on every call. If you want to know what a repair or installation is likely to cost, the best thing to do is call and describe what you're dealing with.
We're based in Medford and serve customers throughout Middlesex County and the surrounding communities. If you're nearby, we can likely get to you quickly. The areas we regularly serve include:

Yes. Medford and the surrounding Middlesex County communities have some of the oldest residential infrastructure in Massachusetts.

Understanding what is in these homes and how it fails is part of what makes us useful to local homeowners.

We serve a wide range of customers, including homeowners, renters coordinating repairs with landlords, landlords managing single-family and multi-unit properties, property managers overseeing commercial buildings, and small business owners. The scope of the job varies, but the standard of care does not.
Yes. If something we repaired or installed does not perform as it should, call us and we will come back and make it right. We do not consider a job finished until the work holds up the way it is supposed to. Transparent pricing and honest workmanship are how we keep customers calling back.
We start every job with a diagnosis. The plumber assesses what is actually wrong, explains what they found, and recommends only the work that addresses the real issue. If a repair will solve the problem, we say so. If a larger fix is genuinely the better long-term answer, we explain why and let you decide.

We handle the full range of plumbing work that Medford homeowners, landlords, and commercial property managers call about, from a slow drain or a dripping faucet to a full sewer line replacement or a whole-home repipe. Every job gets clear communication from the first call to the final test, and we give you a price before any work begins. The table below covers what each service includes, who it is right for, and what is worth knowing before you call.
| Type of Job | What It Covers | When to Call | Worth Knowing |
|---|---|---|---|
| Lead Service Line Replacement |
| Older homes where a lead service line is still present between the house and the street | Replacement eliminates the risk at the source and is often the most reliable long-term solution |
| Faucet & Fixture Installation |
| Renovations, fixture upgrades, or a dripping faucet that needs a permanent fix | Proper installation prevents future leaks at the supply connection |
| Toilet Repair & Installation |
| Homeowners with a constantly running, leaking, or failing toilet | A running toilet can waste hundreds of gallons a week; repair is usually straightforward and fast |
| Leak Detection & Repair |
| Anyone noticing water stains, rising water bills, or unexplained moisture | Finding the source before opening walls saves time and limits damage |
| Sump Pump & Basement Drainage |
| New England homeowners preparing for spring thaw, heavy rain, or a pump that is aging or behaving oddly | A sump pump that runs constantly or cycles erratically often signals a failing switch or a unit near the end of its life |
| Sewer & Main Line Service |
| Properties with slow drains throughout the house, sewage odors, or a known backup | Camera inspection confirms the problem before any digging or repair work begins |
| Emergency Plumbing |
| Any situation that cannot wait for a scheduled appointment | We are available every day including weekends and after regular business hours |
| Frozen Pipe Repair |
| Homeowners dealing with no water flow during or after a hard New England freeze | A pipe that has frozen once is more likely to freeze again; we assess the run and recommend a lasting fix |
| Cast-Iron Drain Stack Replacement |
| Older homes where the main drain stack is corroding, cracking, or causing recurring drain problems | Cast-iron stacks in pre-1970s homes can deteriorate from the inside; camera inspection confirms whether replacement is warranted |
| Water Pressure & Shutoff Valve Repair |
| Homes with noticeably low or inconsistent water pressure | A failing pressure regulator is a common culprit and is straightforward to replace |
| Drain Cleaning & Clog Removal |
| Homeowners and landlords dealing with slow or backed-up drains | Recurring clogs often mean buildup deeper in the line; hydro jetting clears what a snake cannot reach |
| Water Heater Repair & Replacement |
| Households with no hot water, a leaking unit, or an aging water heater losing efficiency | Replacement is often more cost-effective than repeated repairs on a unit over ten years old |
| Sewer Line Replacement |
| Properties with cracked, root-intruded, or collapsed clay or cast-iron sewer lines | Tree root intrusion and ground movement are common causes of line failure in older Middlesex County neighborhoods |
| Whole-Home Repiping |
| Older Medford homes with corroding galvanized pipe, discolored water, or persistent low pressure | Most whole-home repipes take one to two days; the result is a water system that does not need constant attention |
| Garbage Disposal Service |
| Homeowners with a disposal that hums, leaks, or will not turn on | Most disposals have a reset button; if that does not fix it, the unit may need replacement |
How do I know if my water heater needs to be replaced or just repaired?
Age is the first thing we look at. A tank water heater that is more than ten years old and showing problems, whether that is inconsistent hot water, rust-colored water, or a leak at the base, is often a better candidate for replacement than repair. If the unit is newer and the issue is a failed heating element or a faulty thermostat, repair usually makes more sense. We assess the unit on-site and give you a straight answer about which path is worth the money.
What is the difference between hydro jetting and drain snaking?
A drain snake breaks through a clog and restores flow, which handles most residential blockages well. Hydro jetting uses high-pressure water to scour the interior of the pipe, clearing grease buildup, mineral deposits, and debris that a snake pushes past rather than removes. For drains that clog repeatedly or lines with significant buildup, hydro jetting addresses the cause rather than the symptom.
How do you find a hidden water leak without tearing open walls?
We use camera inspection and pressure testing to locate the source before opening anything up. In many cases we can pinpoint the leak to a specific section of pipe, which limits how much wall or flooring needs to come out. The goal is to find the problem accurately the first time so the repair is targeted and the disruption is minimal.
Upfront Quotes With No Surprise Fees
We give you a clear price before any work begins and hold to it. Transparent pricing with no hidden fees on any plumbing job is the standard we hold ourselves to on every call, not just the straightforward ones.
What are the signs that a sewer line is failing?
Multiple slow drains throughout the house at the same time, sewage odors inside or in the yard, patches of unusually green or wet grass over the sewer line, and recurring backups are all worth taking seriously. Any one of these can point to a blockage or a line that is cracked, root-intruded, or beginning to collapse. A camera inspection confirms what is actually happening before we recommend any repair.
How do tree roots damage a sewer line?
Roots follow moisture, and the small gaps at pipe joints in older clay or cast-iron lines are enough of an entry point. Once inside, roots grow and expand, eventually cracking the pipe or blocking flow entirely. Homes with large trees near the sewer line run, or with older clay lines, are the most common candidates. We scope the line with a camera to see how far the intrusion has gone and whether cleaning, repair, or replacement is the right call.
How long does a whole-home repipe take?
Most whole-home repipes in a standard single-family home take one to two days. The timeline depends on the size of the house, how accessible the existing pipes are, and what material is being replaced. We walk through the scope with you before work begins so you know what to expect, including when water will be shut off and for how long.
Experienced With Older and Newer Homes
Medford and the surrounding Middlesex County communities have some of the oldest residential plumbing in Massachusetts. We work in older homes regularly and understand what galvanized pipe, cast-iron stacks, and aging clay sewer lines actually look like and what they need.
What causes low water pressure throughout the house?
Low pressure that affects every fixture at once usually points to a failing pressure regulator, a partially closed main shutoff valve, or buildup inside the supply lines. In older homes with galvanized pipe, corrosion narrows the interior of the pipe over time and reduces flow. We diagnose the cause before recommending a fix, whether that is a regulator replacement, a valve adjustment, or a conversation about repiping.
Do I need to be home when the plumber arrives?
For most service calls, yes. Someone needs to let us in, review what we find, and approve the estimate before work begins. We do not start any job without your sign-off on the price and scope. If you are a property manager coordinating service at a tenant-occupied unit, we can work through the logistics of access and communication for that situation when you call.
Same-Day and Emergency Availability
We offer same-day scheduling for most service calls and respond to plumbing emergencies every day of the week. Work performed by licensed plumbers is available when you need it, not just during business hours.
How does your pricing work, and will I know the cost before work starts?
We give you a clear price before any work begins. We look at the actual job, account for what is involved, and give you a number you can count on. There are no hidden fees added at the end. If something unexpected comes up once we are into the work, we tell you before we proceed, not after.
My sump pump is running constantly. Is that a problem?
A sump pump that runs without stopping usually means one of a few things: the float switch is stuck, the pump is undersized for the water volume coming in, or the discharge line is cycling water back into the pit. It can also mean the pump is working harder than it should and wearing out faster than normal. We assess the pump, the pit, and the discharge setup and tell you honestly whether a repair or replacement makes sense.
What should I do if a pipe bursts?
Shut off the main water supply to the house first. That valve is usually near the water meter or where the main line enters the building. Then call us. The faster the water is off, the less damage spreads into walls, floors, and ceilings. We respond to burst pipe calls as an emergency and will walk you through next steps on the phone while we are on the way.
Every plumbing situation is a little different, so call us and we will walk you through what your job involves, what it costs, and when we can get there.
