New Canaan is a town where the houses are older, the lots are generous, and the plumbing systems underneath them have often been running for decades without much attention. JMK Plumbing & Heating covers New Canaan and the surrounding area for the full range of residential and commercial plumbing work: drain cleaning, leak detection, water heater repair and replacement, sewer line service, repiping, and urgent calls when something goes wrong without warning. Whether you own a single-family home that has seen a few generations of repairs or manage a property with tenants who need things working today, we handle the plumbing side start to finish.
Call (475) 426-2879 for a quote. We are available every day from 5:30 AM to 8:30 PM, and same-day service is often available for calls that cannot wait.
Most plumbing calls start inside the house. A drain that has stopped moving, a fixture that is leaking, a pipe that burst during a cold stretch. Those are repairs we handle at the source, inside the home, with work performed by licensed plumbers who scope the job before anything is opened up.
The harder calls are the ones where the problem is not inside at all. When drains back up throughout the house at the same time, when sewage odor appears in the yard, or when a camera inspection shows root intrusion or joint separation in the lateral, the issue is in the line running from the house out to the municipal connection. That is a different job from a fixture repair, and it requires a different approach. We inspect the line, identify where the failure is, and repair or replace what needs to go. The job is scoped and priced before a wrench comes out, so you know what you are agreeing to before work begins.
Older homes in this part of Fairfield County often have cast-iron or clay sewer laterals that have been in the ground long enough to crack, offset, or collect root intrusion from mature trees. Catching a failing line before it collapses is significantly less disruptive than dealing with one that already has.
Same-day appointments are often available, and we are open every day from 5:30 AM to 8:30 PM. That window covers early-morning calls before a workday starts and evening situations that come up after business hours. When a problem will not keep, call and describe what is happening. We ask a few questions to understand the scope, give you a price, and get someone out as quickly as the schedule allows.
For rental properties and occupied buildings, we work around tenants and business operations rather than against them. A repair that has to happen in a unit someone is living in is handled with care. We protect floors and finishes while we work, and we leave the space the way we found it. The next visit gets earned by doing this one right.
Planned work is handled the same way as urgent calls: call, get a price, confirm the schedule. If you are planning a bathroom renovation, a kitchen update, or any project that involves rough-in or fixture installation, scheduling ahead gives you the most flexibility on timing.
A failing pressure regulator is one of the more common reasons water pressure drops or behaves inconsistently throughout a home. When the regulator goes, pressure can fall too low to be useful or spike high enough to stress fixtures and supply lines. Replacing it is a straightforward repair that restores stable pressure throughout the house. If you are seeing pressure that varies from room to room or changes without explanation, the regulator is worth checking.
A toilet that rocks at the base, leaks at the floor, or runs constantly is not just an annoyance. A slow leak at the wax seal can cause water damage to the subfloor over time, and a running toilet adds up on a water bill faster than most people expect. We reseat toilets that have shifted, replace wax rings that have failed, and swap out units that are beyond practical repair. If you are updating fixtures in a bathroom, we handle the plumbing side of that installation too.
Northeast winters put real pressure on supply lines, particularly in unheated spaces like crawl spaces, exterior walls, and garages. A pipe that freezes and splits can release a significant volume of water in a short time. When that happens, shut off the main water supply if you can and call immediately. We locate the failure, make the repair, and the repair is pressure-tested before the job is called done.
Basements in this part of Connecticut deal with groundwater pressure from spring snowmelt, heavy rain, and the clay-heavy soil that holds moisture close to foundation walls. A sump pump that is cycling rapidly, running constantly, or failing to start when water rises is a problem that tends to become obvious at the worst possible moment. We install new pumps, replace failed units, and service existing systems. If your basement has taken on water or your current pump is showing its age, call before the next wet season arrives.
A disposal that hums but will not spin, leaks at the flange, or has simply stopped responding is usually a repair or a replacement. We assess the unit and tell you which makes more sense. If you are adding a disposal to a sink that does not currently have one, we handle that installation from the drain connection up.
Homes that have been added onto, converted, or updated in stages often end up with a water heater that was sized for a different version of the house. A unit that was adequate for the original footprint may not keep up once a basement is finished or a bathroom is added. If hot water runs out faster than it used to, or never quite reaches the temperature it should, the heater is worth assessing before assuming it has simply failed.
We service and replace both tank and tankless water heaters. For homes where mechanical space is limited, a tankless unit is a common upgrade that frees up room and eliminates standby heat loss. For larger properties or households with high simultaneous demand, a tank unit sized correctly for the load is often the more practical answer. We walk you through the options based on what is actually there and what the property needs, not on a default recommendation.
When a unit has reached the point where repair costs are approaching replacement costs, we say so. When a repair is the right call, we make it and move on.
A price for plumbing work depends on what the job actually involves. The fixture itself, the condition of the surrounding pipe, how accessible the work area is, and what has to come apart to reach the fault are all factors. A toilet replacement in a straightforward bathroom is a different scope from one where the subfloor has water damage that has to be worked around. A leak repair behind a finished wall involves more than one at an exposed fitting.
When you call, we ask enough questions to give you a realistic number before anyone comes out. That price covers the job as described. If we open something up and find a condition that changes the scope, we tell you before we proceed. You get a straight answer on what it covers and what would change it.
We do not charge for guessing. The job is scoped and priced before a wrench comes out. Call (475) 426-2879 and describe what you are dealing with.
The most common calls are repairs: something stopped working, something is leaking, something is making a noise it should not. These calls start with a diagnosis. We locate the fault, explain what caused it, and give you a price to fix it. In an older home, a repair sometimes reveals a secondary issue in the surrounding pipe or fitting. We tell you what we find and let you decide how to proceed.
Some calls are not really about a single failed component. They are about a system that has reached the end of its useful life. Galvanized steel pipe that has corroded from the inside out, a water heater that has been patched twice already, a sewer lateral that has been cleared of roots every year for a decade. When a repair is only buying time, repiping or full replacement is the more honest answer. We scope that work the same way: price confirmed before anything starts, licensed plumbers handling the job, and the work tested before it is called done.
Renovation projects, bathroom additions, kitchen updates, and new fixture installations are scheduled jobs with a known scope. These benefit from a little lead time. Calling ahead gives us the information we need to show up with the right materials and complete the work in a single visit where possible. The service page carries the full breakdown of what falls within each category.
No guesswork. No shortcuts. No loose ends left behind.
New Canaan is the center of this service area, and the coverage extends across the surrounding communities in Fairfield County. If you are in South Wilton, Darien Downtown, Noroton Heights, Scotts Corners, or Wilton Center, the same service applies. The same response time, the same pricing process, the same work from the same licensed plumbers.
Fairfield County has a range of housing ages and property types, and the plumbing needs reflect that variety. We handle all of it, from a single fixture repair in a newer home to a full repipe in a house that has been standing for a century. One call, and a plumber is on the way.
the page covering plumbing jobs goes into what to expect step by step.
Not usually. We handle the shutoff as part of the job, and in most cases we can isolate just the section of the system we are working on rather than cutting the whole house off. If the situation requires the main supply to be off before we arrive, we will tell you that on the call.
Moving a bathroom to a new location is a significant plumbing project that involves running new supply and drain lines to the new space. It is possible in most homes, though the feasibility depends on the existing layout, the location of the main drain stack, and how far the new fixtures will sit from it. Call and describe what you have in mind and we will tell you what is involved.
Yes. When you call and describe what is happening, we can usually tell you whether the situation is urgent, whether it can wait for a scheduled appointment, and what to do in the meantime if waiting is safe. Do not guess. Call (475) 426-2879 and give us the details.
We tell you what we found before doing anything about it. If we open a wall to reach a leaking pipe and see something else that needs attention, we describe it, explain what it involves, and give you a price before proceeding. Nothing gets added to the scope without your agreement.
We provide documentation of the work performed. If you need records for a landlord, a property manager, or an insurance claim, let us know when you call and we will make sure the documentation covers what you need.
It can. Municipal water service boundaries do not always follow property lines or town lines exactly, and the supply source can affect water quality, pressure, and the type of mineral buildup that develops inside pipes. If you have questions about what is coming out of your supply, your water utility is the right source for that information. We work with whatever supply is at the property.
Yes. We take away the parts we remove, including old fixtures, failed valves, worn pipe sections, and replaced water heater units. If you have questions about what gets hauled out versus left behind, ask on the call and we will be clear about it.
Yes. South Wilton, Darien Downtown, Noroton Heights, Scotts Corners, and Wilton Center are all covered. The scope of work, the pricing process, and the response time are the same across the full service area. If you are not sure whether your address falls within range, call (475) 426-2879 and ask. We will give you a straight answer.
Older homes in this area tend to surface a familiar set of problems: corroded galvanized supply lines, aging sewer laterals with root intrusion, sump pumps that are overdue for replacement, and water heaters that were sized for a smaller household than the one living there now. Drain cleaning and leak detection are the most common single-visit calls. Repiping and sewer line replacement come up when a repair has been deferred long enough that the underlying system needs to be addressed directly.
For straightforward repairs, we can often give you a price range on the call after asking a few questions about the job. For larger or more complex work, the price is confirmed once the job is scoped on site. Either way, you know the number before any work begins.
It does, in practical terms. Homes built before the mid-twentieth century often still have galvanized steel supply lines or cast-iron drain lines that have been in service long enough to corrode, narrow, or crack. A home that has been renovated in stages may have a mix of pipe materials that were connected at different times, which can create pressure inconsistencies or accelerate corrosion at the joints. A licensed plumber can assess what is there and tell you what the condition of the system actually is.
We note the details of every job so that follow-up calls can be handled with the context of what was already done. If continuity matters for your situation, mention it when you call and we will do our best to accommodate it.

Every home and property in New Canaan 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 New Canaan 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 | New Canaan 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 New Canaan'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 New Canaan 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 New Canaan 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 New Canaan 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. |
