JMK Plumbing & Heating is the plumbing contractor Stamford homeowners, landlords, and businesses call when the work needs to get done right. We handle everything from a dripping faucet to a full sewer line replacement, and we're available every day from 5:30 AM to 8:30 PM. Whether you're dealing with a slow drain, a water heater that quit overnight, or a larger project that's been on the list for months, call for a quote and we'll walk you through exactly what it takes. Work performed by licensed plumbers, every job. Good workmanship. Good pricing. Good plumbers.
Most of the calls we get from Stamford homeowners and property managers fall into a familiar set of problems. Here's the full range of what we handle day to day.
Most homeowners can't tell a minor leak from a serious one, and the same goes for a slow drain. What looks like a simple clog at the sink can be a sign of buildup deeper in the line. We clear sink, tub, shower, and floor drains, and we handle main line cleaning when the problem runs further down. Older homes in Stamford often have aging pipe interiors where buildup accumulates faster, and root intrusion into sewer laterals is a recurring issue in this area. We find the blockage, clear it, and tell you what we found.
Not every leak is visible. Supply line leaks, slow seeps behind walls, and pinhole failures in older pipe can do real damage before they're noticed. We locate the source, make the repair, and the repair is pressure-tested before the job is called done. We also handle water line repair and replacement when a section of pipe has reached the end of its useful life. We keep your home dry and your water flowing.
A no-hot-water call is one of the most common urgent requests we get. We service and replace both tank and tankless water heaters. Tankless units are worth considering in Stamford's older homes where mechanical space is limited and the existing tank is oversized for the household. We'll help you understand the options, give you a price, and get the work scheduled. One call, and a plumber is on the way.
Running toilets, loose handles, dripping faucets, outdoor hose bibs that didn't survive the winter. We repair and replace all of it, and we install new fixtures for remodels and renovation projects. We protect your floors and finishes while we work, which matters when the work is happening in a finished bathroom or a newly renovated kitchen.
A disposal that hums but won't spin, one that leaks at the flange, or one that simply stopped working. We repair what's repairable and replace what's not. If you're adding a disposal to a sink that doesn't have one, we handle that installation too.
Low water pressure can point to a partially closed valve, a failing pressure regulator, or a buildup problem in the supply line. We diagnose the cause and make the fix, whether that means adjusting a regulator, replacing a shutoff valve, or clearing a restricted line. Shutoff valves that haven't been turned in years are a common issue in older Fairfield County homes, and a valve that won't close in an emergency is a real problem. Reach out and we'll start at the source of the leak.
Stamford's housing stock is older, its winters are cold, and its wet shoulder seasons put real pressure on basements and drainage systems. The three services below come up regularly in this area for reasons that are specific to the local conditions.
Galvanized steel pipe corrodes from the inside out. In older Stamford homes, that corrosion shows up as rust-colored water, pressure that drops from room to room, or pinhole leaks that keep coming back. Repiping replaces the deteriorated pipe throughout the home with modern material that won't have the same problems. We scope the project, give you a price before anything starts, and work through the job in a way that minimizes disruption to the household.
Sewer lines in Stamford's older neighborhoods deal with two main enemies: age and tree roots. Cast-iron and clay pipe that's been in the ground for decades can crack, offset at the joints, or collapse. Root intrusion is common where mature trees line the streets and yards. When a sewer line backs up repeatedly or a camera inspection shows significant damage, replacement is often the right call. We handle the line from the house out to the connection point. We show up ready to get to work.
Connecticut's spring thaw and heavy rain seasons put real water pressure on basements, and Stamford's coastal proximity means nor'easters can bring sustained rainfall that overwhelms a drainage system fast. A sump pump that fails during a storm is the kind of problem that turns into a much bigger one in a matter of hours. We install new sump pumps, replace failed units, and service existing systems before the wet season hits. If your basement has taken on water or your current pump is showing its age, call for a quote before the next storm.
No guesswork. No shortcuts. No loose ends left behind.
Property managers trust us to keep their buildings running, and that means showing up prepared and getting the work done without dragging out the timeline. We work with landlords, building owners, restaurant operators, property management companies, and businesses across Stamford and the surrounding area. Multi-family properties, office buildings, condos, apartments, retail spaces, and commercial kitchens all have plumbing that needs to stay functional.
We're available every day from 5:30 AM to 8:30 PM, which gives property managers flexibility when a repair needs to happen outside standard business hours. The job is scoped and priced before a wrench comes out, so there are no conversations after the fact about what the work was going to cost. The next visit gets earned by doing this one right.
Scheduling a plumber shouldn't be complicated. When the situation is urgent, the process is simple: call, get a price, and a plumber heads your way. We're open every day from 5:30 AM to 8:30 PM, and same-day service is often available for calls that can't wait.
Burst pipes, major leaks, sewer backups, and no-hot-water calls are the situations we hear about most when a customer needs someone quickly. A burst pipe in a Stamford winter can cause serious damage in a short window, and a sewer backup that's reached the floor drain isn't something to leave until Monday. We handle urgent calls the same way we handle scheduled ones. We show up ready to get to work.
Not every plumber works the same way, and pricing is one of the places where the difference shows up. When you call us, you get a price before anything is scheduled. The job is scoped and priced before a wrench comes out, so you know what you're agreeing to before work begins. Ask what the quote covers and you'll get a straight answer.
That process applies to straightforward repairs and to larger projects alike. If you're planning a bathroom remodel, a kitchen renovation, or new construction in Fairfield County, we can be part of that process from the plumbing side. Rough-in work, fixture installation, supply and drain connections. Call for a quote and we'll talk through what the project needs.
Stamford is our primary market, but we work across a wider stretch of Fairfield County. If you're in Greenwich, Darien, New Canaan, Norwalk, Westport, or Wilton, we cover your area. The housing stock, the infrastructure age, and the seasonal conditions are similar across this part of Connecticut, and the plumbing work we do here reflects all of that.
If you're not sure whether we reach your address, call and ask. We'll give you a straight answer.
Rust-colored water, pressure that varies from fixture to fixture, pinhole leaks that keep returning, and visible corrosion at pipe joints are all common signs that galvanized or aging pipe is failing from the inside. Stamford's older housing stock still has a significant share of homes with galvanized steel or cast-iron supply lines that have run their course. When the same section of pipe keeps leaking, or when rust shows up at multiple fixtures, repiping is often the more cost-effective answer than continued patching. Call for an assessment and we will tell you what is there and what makes sense.
A camera inspection runs a small waterproof camera through the sewer line from an access point inside or outside the home. The footage shows the interior condition of the pipe: cracks, root intrusion, joint offsets, buildup, or sections that have collapsed. It is the most accurate way to understand what is happening in the line before recommending a repair or replacement. If you are dealing with recurring backups or slow drains throughout the house, a camera inspection is the right starting point.
A water heater that is past its useful life can cause sediment buildup in the tank that reduces heating efficiency and eventually makes its way into supply lines and fixtures. Pressure relief valves on old units can fail, and a slow leak at the base of the tank can go unnoticed until there is real water damage. We diagnose the unit before recommending repair or replacement, and we walk you through the options based on the age and condition of what is there.
A burst pipe, a major active leak, a sewer backup that has reached living areas, or a complete loss of hot water are the situations that call for same-day service. If water is actively flowing where it should not be, shut off the main supply if you can and call immediately. We are open every day from 5:30 AM to 8:30 PM and emergency calls are prioritized.
Galvanized steel pipe corrodes from the inside out over time. As the pipe interior narrows from rust and mineral buildup, pressure drops throughout the home. The same corrosion weakens joints and fittings, which is why older homes often develop leaks at multiple points rather than just one. A pressure regulator that has failed can also cause pressure problems throughout the house. We diagnose the cause before recommending a fix.
Water stains on ceilings or walls, a mildew smell in a room that does not have an obvious moisture source, paint or wallboard that is bubbling or soft, and a water bill that has climbed without explanation are all common indicators of a hidden leak. Supply line leaks behind walls and slow seeps at pipe joints can cause significant damage before they become visible. If you are seeing any of those signs, call us and we will locate the source.
A toilet that runs continuously after flushing, one that cycles on and off on its own, or one with water visible on the floor around the base are all signs of a problem worth addressing. A running toilet can waste a significant volume of water over a billing cycle, often showing up as an unexplained spike in the water bill. The fix is usually a flapper, fill valve, or wax ring replacement, all of which are straightforward repairs. Call and we will assess which component is the issue.
Before purchasing a home in Stamford or Fairfield County, a plumbing inspection is worth scheduling to understand the condition of the supply lines, drain lines, water heater, and fixtures. It is also a reasonable step if you have moved into an older home and do not have a clear picture of what the system looks like. We can inspect the accessible plumbing and give you an honest assessment of what is there and what, if anything, needs attention.
Yes. We install new disposals in sinks that do not currently have one, replace units that have failed, and repair disposals that are humming but not spinning or leaking at the flange. If you are not sure whether a repair or replacement makes more sense, we will assess the unit and give you a straight answer. Call for a quote and we will tell you what the job involves.
Outdoor faucet and hose bib repair and replacement, exterior shutoff valve service, and underground supply line work all fall within our scope. Connecticut winters are hard on outdoor plumbing, and hose bibs that were not properly winterized are a common source of leaks in the spring. We assess the exterior plumbing as part of a broader diagnosis when the problem could involve an outdoor connection.
Frozen ground can slow or pause excavation work on sewer lines and underground supply lines during deep winter. Outdoor pipe repairs are also more difficult to pressure-test in extreme cold. We schedule exterior and underground work with the weather in mind and will tell you on the call if timing is a factor for your specific job. For urgent situations, we assess what can be done safely and proceed accordingly.
Same-day appointments are often available for both urgent and non-urgent calls. We are open every day from 5:30 AM to 8:30 PM, which means a call placed early in the morning can often result in a same-day visit. Call (475) 426-2879 and describe the situation, and we will tell you the earliest available time.

Every home and property in Stamford has its own plumbing history, and the work that comes up most often reflects the age of the housing stock, the climate, and how the systems have been maintained over time. The table below covers the full range of what we handle, from a straightforward drain cleaning to a whole-home repipe, so you can find the service that fits your situation and call for a quote. Work is performed by licensed plumbers on every job. If you have a question that the table does not answer, the FAQs below cover the specifics.
| Type of Job | What the Job Covers | Recommended For | Worth Knowing |
|---|---|---|---|
| Water Heater Repair & Replacement | tank water heater service, tankless unit installation, sediment flush and maintenance, no-hot-water diagnosis | Homes with no hot water or an aging unit | Tankless units are a practical choice in older Stamford homes where mechanical space is limited. We walk you through the options and price the job before scheduling. |
| Emergency Plumbing | burst pipe response, major active leak control, sewer backup service, no-hot-water urgent calls | Any situation where water is flowing where it should not be | We are open every day from 5:30 AM to 8:30 PM. If water is actively flowing, shut off the main supply if you can and call immediately. |
| Sump Pump & Basement Drainage | sump pump installation and replacement, failed pump service, basement drainage assessment, pre-season system check | Basements that have taken on water or homes with aging or failed sump pumps | Connecticut's spring thaw and nor'easter seasons put real pressure on basement drainage. A pump that fails during a storm can turn into a much larger problem in a matter of hours. |
| Frozen Pipe Repair | frozen pipe thawing, burst pipe repair after freeze, vulnerable pipe assessment, supply restoration | Homes with no water flow during or after a cold snap | Stamford winters regularly push temperatures below freezing. Pipes in unheated spaces, crawl spaces, and exterior walls are the most common points of failure. |
| Faucet & Fixture Installation | faucet repair and replacement, outdoor hose bib service, fixture installation for remodels, supply and drain connections | Dripping faucets, remodel projects, or fixture upgrades | We protect floors and finishes while we work, which matters when the job is in a finished bathroom or a recently renovated kitchen. |
| Cast-Iron Drain Stack Replacement | deteriorated stack removal, modern drain stack installation, multi-story drain system repair, fixture reconnection | Older multi-story homes with cracking, rusting, or leaking cast-iron drain stacks | Cast-iron drain stacks in Stamford's older housing stock can crack and corrode over decades. A failing stack affects every fixture tied to it, so replacement is a whole-system fix. |
| Drain Cleaning & Clog Removal | sink, tub, and shower drains, floor drain clearing, main line cleaning, root intrusion removal | Slow or stopped drains at any fixture | Recurring clogs in older Stamford homes often point to buildup deeper in the line, not just at the fixture. We find the blockage and tell you what we found. |
| Lead Service Line Replacement | lead service line identification, full line replacement, connection to city main, interior lead pipe removal | Older Stamford homes where the original service line has not been replaced | Many homes built before the 1980s in this area still have lead service lines. Replacement is the only way to eliminate lead as a source of contamination at the tap. |
| Toilet Repair & Installation | flapper and fill valve replacement, wax ring and seal repair, full toilet replacement, running or leaking toilet diagnosis | Running, leaking, or loose toilets in any bathroom | A running toilet can add a significant amount to a water bill over a single billing cycle. Most repairs are completed in a single visit. |
| Garbage Disposal Service | disposal repair, full unit replacement, new disposal installation, flange and seal repair | Disposals that hum, leak, or have stopped working | If a disposal is repairable, we repair it. If replacement makes more sense given the age and condition, we tell you that before any work starts. |
| Water Softener Installation | softener unit installation, supply line connection, bypass valve setup, existing softener replacement | Homes with hard water causing scale buildup on fixtures and in appliances | Hard water shortens the life of water heaters and leaves buildup on faucets and fixtures. We install the supply connections and integrate the softener into the existing plumbing. |
| Water Pressure & Shutoff Valve Repair | pressure regulator diagnosis and replacement, shutoff valve replacement, supply line restriction clearing, whole-home pressure assessment | Low pressure throughout the home or valves that will not close | Shutoff valves that have not been turned in years are a common issue in older Fairfield County homes. A valve that will not close in an emergency is a real problem. |
| Sewer Line Replacement | cast-iron and clay pipe replacement, root intrusion remediation, collapsed or offset joint repair, line replacement to connection point | Sewer lines with confirmed damage, repeated backups, or significant root intrusion | Mature trees along Stamford streets and yards make root intrusion into sewer laterals a recurring issue. When camera footage shows significant damage, replacement is often the right call. |
| Leak Detection & Repair | supply line leak location, pipe repair and replacement, pressure testing after repair, wall and hidden leak diagnosis | Visible or suspected leaks anywhere in the home | The repair is pressure-tested before the job is called done. If the source is behind a wall, we locate it before opening anything. |
| Sewer & Main Line Service | sewer line cleaning, camera inspection, main line clog clearing, line condition assessment | Backups affecting multiple fixtures or recurring slow drains throughout the home | A camera inspection is the most accurate way to understand what is happening in the line before recommending repair or replacement. |
| Whole-Home Repiping | galvanized pipe replacement, modern material installation, full supply system repipe, pressure and flow restoration | Older homes with rust-colored water, recurring leaks, or dropping pressure room to room | Galvanized steel corrodes from the inside out. When pinhole leaks keep coming back at multiple points, repiping is often more cost-effective than continued patching. |
How do I know if my water heater needs repair or full replacement?
Age and condition are the two factors that matter most. A unit that is producing rusty or discolored water, making rumbling or popping sounds, or leaking at the base is often past the point where repair makes sense. Sediment that has built up over years reduces efficiency and can eventually damage the tank lining. We assess the unit before recommending anything, and we walk you through the options based on what we find rather than defaulting to replacement.
What is the difference between a tank and a tankless water heater?
A tank water heater stores a set volume of hot water and reheats it as it is used. A tankless unit heats water on demand as it flows through the system, which means it does not run out the way a tank can during back-to-back showers. Tankless units take up less space, which makes them a practical option in older Stamford homes where the mechanical room is tight. The right choice depends on the household's usage pattern, the existing fuel source, and the available space. We give you a clear comparison and a price for each option before anything is scheduled.
How can I tell if a clog is at the fixture or deeper in the main line?
A clog at a single fixture, like one slow sink or one backed-up tub, is usually a localized problem in the drain arm or P-trap. When multiple fixtures are slow or backing up at the same time, or when water comes up in one fixture when another is used, the problem is almost always in the main line. Older Stamford homes with cast-iron or clay sewer laterals are particularly prone to buildup and root intrusion deeper in the system. We diagnose the location before clearing anything so the fix addresses the actual source.
Scope Agreed Before Any Pipe Is Cut
The job is scoped and priced before a wrench comes out. You know what you are agreeing to before work begins, and you get a straight answer when you ask what the quote covers.
What causes low water pressure throughout the whole house?
Whole-home pressure loss usually points to one of three things: a failing pressure regulator, a partially closed or corroded shutoff valve, or buildup inside aging supply pipe. In older homes with galvanized steel supply lines, corrosion narrows the pipe interior over time and reduces flow to every fixture. A pressure regulator that has failed can cause pressure to drop or spike unpredictably. We diagnose the cause before recommending a fix, because the right repair depends on what is actually driving the problem.
When does a drain clog call for hydro jetting instead of snaking?
Snaking breaks through a clog and restores flow, but it does not clear the buildup coating the pipe walls. Hydro jetting uses high-pressure water to scour the interior of the pipe, which is more effective for grease accumulation in kitchen lines, heavy buildup in older pipe, and root intrusion that a snake can punch through but not remove. For commercial kitchens and multi-family properties where the same line clogs repeatedly, hydro jetting is often the more durable solution. We assess the line and recommend the method that makes sense for the situation.
How do tree roots get into a sewer line and what does the damage look like?
Roots follow moisture, and the joints in older clay and cast-iron sewer pipe are a reliable source of it. Over time, roots work their way through small gaps at the joints, grow inside the pipe, and eventually restrict or block flow entirely. In Stamford neighborhoods with mature street trees and older sewer laterals, this is a recurring issue rather than a rare one. A camera inspection shows the extent of the intrusion and whether the pipe itself is structurally intact or has cracked and offset at the joints. That information determines whether clearing the roots is enough or whether section replacement is the right call.
Work Performed by Licensed Plumbers
Every job, whether it is a faucet replacement or a full sewer line replacement, is handled by licensed plumbers. That applies to the everyday calls and the larger projects alike.
What causes a sump pump to fail and what are the warning signs?
Sump pumps fail for a few common reasons: the float switch sticks or fails, the motor burns out from running continuously during a heavy rain event, or the pump simply ages out after years of use. Warning signs include a pump that runs but does not move water, one that cycles on and off rapidly, one that makes unusual sounds, or one that does not activate at all when the pit fills. Connecticut's wet spring season and nor'easter storms put real demand on basement drainage systems. If a pump is showing any of those signs before the wet season, it is worth having it assessed before a storm makes the decision for you.
Do I need a permit for plumbing work in Stamford?
Permit requirements depend on the scope of the work. Straightforward repairs like replacing a faucet or a toilet typically do not require a permit. Larger projects, including water heater replacement, repiping, sewer line replacement, and new fixture rough-in work, often do. Requirements can also vary depending on whether the work is in the city limits or in an unincorporated part of Fairfield County. We confirm what applies to your specific job before work starts, and work performed by licensed plumbers follows the code requirements for the jurisdiction.
Experienced With Older and Newer Homes
Stamford's housing stock runs from century-old colonials to newer construction, and the plumbing in each requires a different approach. We work with what is there and tell you honestly what it needs.
How long does a whole-home repipe typically take?
The timeline depends on the size of the home, the number of fixtures, and how the existing pipe is routed. A straightforward repipe in a single-family home can often be completed in two to three days. Larger homes or those with more complex layouts take longer. We scope the project before scheduling so you have a realistic picture of the timeline and what the work involves before anything starts. Water is restored each day before we leave the job.
What should I do if a pipe bursts during a Stamford winter?
Shut off the main water supply at the shutoff valve as quickly as you can. If you are not sure where the main shutoff is, finding it before cold weather arrives is worth the few minutes it takes. Once the water is off, call us. We are open every day from 5:30 AM to 8:30 PM, and burst pipe calls are handled as urgent. The longer water flows after a pipe fails, the more damage accumulates, so getting the supply off is the most important first step.
Is it worth trying to fix a plumbing problem myself before calling a plumber?
Some tasks are straightforward enough that a handy homeowner can handle them without risk: tightening a loose supply line connection, replacing a showerhead, or resetting a tripped garbage disposal. The line is usually drawn at anything that involves cutting into pipe, working inside the wall, or touching the main shutoff or pressure regulator. A repair that seems simple but is done incorrectly can create a leak that does not show up for weeks. If you are not certain what the fix involves or whether it requires a permit, a call for a quote costs nothing and gives you a clear picture before you commit to either path.
