JP Walsh Plumbing & Heating has been serving Medford and the surrounding Middlesex County communities since 2012. We handle everything from a dripping kitchen faucet to a full sewer line replacement, and we show up ready to work whether the call comes in on a Tuesday morning or a Saturday afternoon. Same-day appointments are available for most jobs, and we serve both residential and commercial customers across the area. Clear communication from the first call to the final test is how we run every job. You know what the work involves, what it costs, and what to expect before we touch a pipe.
Simple booking. Clear pricing. Sound, lasting pipes.
For busy homeowners and property managers, finding a plumber who handles the full scope of everyday plumbing work without the runaround is worth a lot. We cover drain cleaning, leak detection, water heaters, toilets, faucets and fixtures, sewer and main line service, garbage disposals, water pressure issues, shutoff valves, and repiping. Residential customers, landlords, and commercial property owners all get the same attention. Experienced plumbers who respect your home show up on time, protect your floors and walls, and leave the work area clean.
A slow drain is an easy thing to ignore until it backs up completely. We clear kitchen drains, bathroom sinks, shower and bathtub drains, floor drains, and main drain lines. Depending on what we find, we use drain snaking for most residential clogs and hydro jetting for tougher blockages or buildup that keeps coming back. The goal is a drain that flows the way it should, not a temporary fix that fails in a month.
Water leaks do the most damage when they stay hidden. We use camera inspection and other diagnostic tools to find the source of a leak before it spreads further into walls, floors, or ceilings. From water line leaks and pipe joint failures to gas line leaks at the supply line, we locate the problem and repair it correctly. The fix addresses the cause, not just the symptom.
No hot water is one of those problems that cannot wait. We repair and replace both tank and tankless water heaters, and we handle water heater leaks before they turn into a bigger mess. If your unit is aging and losing efficiency, we can walk you through replacement options that fit your household's demand. Domestic hot water is what we do, and we keep the job straightforward from start to finish.
A running toilet wastes more water than most people realize, and a dripping faucet adds up fast on a water bill. We handle toilet repair and replacement, faucet repair and installation for kitchen, bathroom, shower, and bathtub, sink installation, and garbage disposal repair and installation. Whether you are upgrading fixtures in a renovation or replacing something that finally gave out, we get it done right and move on.
Sewer problems rarely announce themselves politely. We handle sewer line cleaning, sewer backup repair, sewer camera inspection, trenchless sewer repair where conditions allow, and water main repair and replacement. When a main line backs up or a service line fails, we find the problem with a camera, explain what we found, and give you a clear path forward. We speak only to the line itself, from the house to the connection point.
Low water pressure is frustrating, and it usually points to something specific: a failing pressure regulator, a partially closed shutoff valve, or buildup inside the line. We diagnose the cause, replace pressure regulators and shutoff valves, install backflow preventers, and repair outdoor faucets and hose bibs. This is the behind-the-scenes work that keeps a home's plumbing reliable year after year.
Give us a ring and we'll take it from there.
Your time matters, so we keep the plumbing job on schedule, and that same principle applies when something goes wrong in the middle of the night. We are available for same-day service on most calls and for emergency plumbing when it cannot wait. Burst pipes, major leaks, and sudden loss of hot water all qualify. We cover weekend and after-hours calls because plumbing problems do not follow a business schedule. Straight answers about your pipes and fixtures, no surprises is the standard we hold ourselves to on every emergency call, not just the routine ones.
Quick to arrive. Careful with your home. Clean when we leave.
One call, and a plumber is on the way.
Doing plumbing work right matters, and we'll help you get it right, especially in a place like Medford where the housing stock tells its own story. Middlesex County has some of the oldest residential infrastructure in Massachusetts. That means galvanized pipe, aging cast-iron drain stacks, worn clay sewer lines, and basements that have been fighting moisture since before anyone alive can remember. The three services below come up constantly in this area, and we handle each one with the care that older homes require. We also repair frozen pipes during harsh New England winters and replace lead service lines where they are still present. Reach out and we'll start at the source of the leak.
Galvanized pipe corrodes from the inside out. Over decades, the interior narrows, water pressure drops, and discolored water becomes a daily problem. In older Medford homes, galvanized and aging copper supply lines are common, and at some point patching individual sections stops making sense. Whole-home repiping means assessing what is in the walls, replacing the supply lines with PEX or copper throughout, and restoring full pressure and flow to every fixture in the house. The work is disruptive for a day or two, but the result is a water system that does not need constant attention.
Clay and cast-iron sewer lines laid decades ago were built to last, and many of them have. But tree root intrusion, ground movement, and simple age eventually win. We use camera inspection to confirm the condition and scope of the line before recommending replacement. Where site conditions allow, trenchless methods can reduce the digging involved. When a full replacement is the right call, we handle it from the house connection to the point of tie-in. We stay on the line itself and leave the rest to the appropriate trade.
A New England basement without a working sump pump is a risk, particularly during spring thaw or a heavy nor'easter. When the water table rises and it has nowhere else to go, the sump pump is the last line of defense against flooding and the damage that follows. We install, repair, and replace sump pumps, and we also service ejector pumps and sewage pumps in finished or below-grade spaces. If your pump is running constantly, cycling oddly, or simply old, we will tell you honestly whether a repair makes sense or whether replacement is the better move.
Good plumbing work isn't complicated, it's just done right, and the same goes for the bill at the end of the job. We provide upfront quotes before work begins so you are not guessing at the final number. Transparent pricing with no hidden fees on any plumbing job is not a marketing line for us; it is how we keep customers calling back and referring their neighbors. When you ask for an estimate, we look at the actual job, account for what is involved, and give you a number you can count on. We're one phone call from getting your plumbing right.
We are based in Medford and work throughout Middlesex County, covering both residential and commercial customers across the area. Nearby communities we serve regularly include Somerville, Malden, Everett, Arlington, Winchester, and Cambridge. If you are a homeowner, a landlord managing multiple units, or a property manager responsible for a commercial building, we handle the plumbing work across all of it. Call us and a real local person picks up. We know the neighborhoods, the housing stock, and the kinds of problems that come up here.
No guesswork. No shortcuts. No bill-day surprises.
We're one phone call from getting your plumbing right.
Call (339) 545-3923 and describe what you are dealing with. We offer same-day scheduling for most service calls in Medford and the surrounding area, and a real local person picks up when you call. We will let you know when we can be there and what to expect before the plumber arrives.
Yes. We are available every day from 8:30 AM to 10:00 PM, including Saturdays and Sundays. Plumbing problems do not follow a Monday-through-Friday schedule, and neither do we. Call for a quote any day of the week and we will get you on the schedule.
A burst pipe, a major active leak, a sewer backup, or a sudden loss of hot water all qualify as plumbing emergencies. We are available every day until 10:00 PM, and for situations that genuinely cannot wait, we respond to after-hours calls as well. Call (339) 545-3923 and describe what is happening so we can assess how quickly we need to get there.
Yes. We work with homeowners, landlords, property managers, and commercial building operators throughout Medford and Middlesex County. The scope of work varies, but the standard is the same: clear communication, honest pricing, and work done right the first time.
A brief description of the problem is the most useful thing. If you know where the issue is located in the home, roughly how long it has been going on, and whether it is getting worse, that helps us give you a more accurate picture over the phone. You do not need to diagnose the problem yourself before calling.
The plumber will assess the situation, explain what they find, and give you a clear price before any work begins. We do not start work without your approval. Once you agree to the estimate, we get to it, work cleanly, and leave the space in good shape when the job is done.
For most service calls, yes. Someone needs to be present to let the plumber in, review the estimate, and approve the work before it starts. If you are a property manager coordinating service at a tenant-occupied unit, we can discuss the best way to handle access and communication for that situation.
Dropping water pressure, discolored water, recurring leaks, or a water bill that is climbing without an obvious reason are all signs worth paying attention to. Many homes in Medford have galvanized or aging copper supply lines that corrode from the inside over time. A plumber can assess what is in the walls and tell you honestly whether a repair or a full replacement makes more sense.
A single visit can cover a wide range depending on the job. Common calls include drain cleaning, leak repair, water heater diagnosis and replacement, toilet and faucet repair or installation, shutoff valve replacement, and water pressure diagnostics. If the job is larger, such as a sewer line issue or a repiping project, we assess the scope on the first visit and give you a clear plan before scheduling the work.
JP Walsh Plumbing & Heating has been at this since 2012, and the work speaks for itself. Same-day availability, transparent pricing, and a full range of plumbing services from a team that treats your home with care. Whether you need a leaky faucet fixed today or a full sewer line replaced next week, we are ready to help. Call (339) 545-3923 to get a quote or schedule a service call. We will walk you through what the job involves and what it costs before anything gets started.
Give us a ring and we'll take it from there.
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.
