Mamaroneck has a mix of property types that puts a real range of plumbing work on the schedule. Single-family homes on the older end of the housing stock carry galvanized pipe, aging fixtures, and sewer laterals that have been in the ground long enough to show their age. Condos and smaller multi-unit buildings generate fixture work, drain calls, and water heater replacements that need to happen without shutting down the whole building. JMK Plumbing & Heating handles all of it, from the straightforward repair to the larger project that takes more than one visit to complete.
Landlords and building managers in Mamaroneck deal with a different kind of pressure than a homeowner does. A tenant without hot water is not a problem that can wait until next week, and a drain backup in a shared building affects more than one household at once. We work around occupied units, coordinate with whoever holds the keys, and get the problem resolved without turning a single repair into a full-day disruption. Call (475) 426-2879 for a quote on any plumbing work in Mamaroneck.
Low pressure at a single fixture usually points to a localized problem. A clogged aerator, a partially closed shutoff valve, or a failing cartridge inside the faucet can all reduce flow at one tap while leaving the rest of the house unaffected. Those are straightforward to diagnose and quick to correct. The job is scoped and priced before a wrench comes out, so you know what you are agreeing to before anything is taken apart.
When pressure is low throughout the whole property, the cause is further upstream. A failing pressure-reducing valve is one of the more common culprits in this area, particularly in homes where the valve has never been replaced. Mineral buildup inside older galvanized pipe narrows the interior diameter over time, which reduces flow to every fixture at once. In some cases, a supply line leak is bleeding pressure before the water reaches the house. We run through the diagnostics in order and fix what is actually causing the problem, not what is easiest to reach first. We keep your home dry and your water flowing.
Uneven pressure across a multi-story property is its own situation. Upper floors often show lower pressure than ground-floor fixtures, and in a building with aging supply lines that gap can become significant. Shutoff valve replacement, pressure regulator adjustment, and supply line repair all play a role depending on what the diagnosis turns up.
Same-day service is often available in Mamaroneck, and that matters most when the problem will not wait. A burst pipe, a sewer backup reaching the floor, or a water heater that stopped working overnight are the calls that move to the front of the schedule. We are open every day from 5:30 AM to 8:30 PM, which covers early-morning calls before a workday starts and evening situations that come up after business hours.
For scheduled work, the process is straightforward. You call, describe what is going on, and we give you a price and a time. If the property is occupied by tenants, we work around their schedule rather than asking them to work around ours. A repair that requires isolating water to part of a building can often be done in a window that minimizes disruption, and we plan for that on the call before anyone comes out.
Scheduling a plumber shouldn't be complicated. One call, and a plumber is on the way.
Commercial properties in Mamaroneck include retail spaces, restaurants, and office buildings that have plumbing running through occupied floors. Shutting off water to the whole building to fix a problem on one floor is not always an option. We isolate the affected section where the layout allows it, which keeps the rest of the building functional while the repair is underway. That requires knowing the supply layout before starting, and we take the time to understand it.
Restaurants and food-service properties have drain systems that take a harder daily load than most residential plumbing. Grease buildup, heavy fixture use, and the volume of water moving through a commercial kitchen create conditions where a clog or a slow drain is more disruptive than it would be at home. We schedule drain cleaning and fixture work during hours that do not conflict with service, and we get the line running properly before we leave. Work performed by licensed plumbers, every call.
The price depends on what the job actually involves, and that is not always clear until a plumber has looked at it. A dripping faucet and a corroded supply line behind the wall are not the same job, even if they start with the same symptom. When you call, we ask enough questions to give you a realistic number before anything is scheduled. If the job turns out to be more involved once we are on site, we tell you before we proceed, not after.
What moves a quote up is generally access and scope. A fixture swap in an open, easy-to-reach location is a different job from the same fixture swap where the supply lines are corroded, the shutoff valve will not close, and the wall needs to come open to reach the connection. We scope the job honestly and price it that way. The next visit gets earned by doing this one right.
A tankless unit heats water on demand rather than holding a tank at temperature around the clock. In Mamaroneck homes where mechanical space is limited, the wall-mounted footprint is a practical advantage. Installation involves connecting the unit to the gas or electric supply, running the appropriate venting, and tying into the existing domestic water lines. We size the unit for the household's demand and walk you through the options before anything is ordered.
A new sink or vanity is often part of a bathroom or kitchen update, and the plumbing side of that job involves more than connecting two supply lines. Drain alignment, shutoff valve condition, and supply line length all need to work with the new fixture. We handle the rough-in connections and the finish work, and we check for leaks at every joint before the job is called complete. The repair is pressure-tested before the job is called done.
Backflow preventers stop contaminated water from flowing back into the supply. They require periodic inspection and, when they fail, replacement. We test the device, identify whether it is operating correctly, and replace it when it is not. This is common on irrigation connections and on properties where the supply line crosses a potential contamination source.
A refrigerator with a water dispenser or ice maker needs a dedicated supply line run to the back of the unit. We install new lines, repair lines that have developed a slow drip behind the appliance, and replace saddle-valve connections with proper shutoff valves that will not fail over time. A slow leak behind a refrigerator can go unnoticed for months, so it is worth checking if the appliance has been in place for years without a line inspection.
A toilet that runs between flushes is wasting water on every billing cycle. The cause is usually a worn flapper, a fill valve that is no longer seating properly, or a float set too high. We diagnose which component is failing and replace it. A toilet that leaks at the base points to the wax ring, which requires pulling the fixture to reseat it correctly. Neither repair is complicated, but leaving either one unaddressed adds up over time.
Galvanized steel pipe corrodes from the inside out. Polybutylene, a gray plastic pipe installed through the 1970s and 1980s, becomes brittle and prone to failure as it ages. Both materials show up in Westchester County's older housing stock, and both reach a point where patching individual sections is no longer the right answer. We assess what is in place, explain what we find, and replace the affected lines with material that will not have the same problems going forward.
Some calls are straightforward: a faucet drips, a toilet runs, a drain is slow. Others start with a symptom and require real diagnosis before the repair can begin. A water bill that has climbed without explanation, pressure that drops at certain times of day, or a wet spot on the ceiling below a bathroom all point to something that needs to be located before it can be fixed. We work through it in order and give you a clear picture of what we found.
When a fixture, a water heater, or a section of pipe has reached the end of its useful life, replacement is the more cost-effective answer. Repiping a home with corroded galvanized supply lines, replacing a sewer lateral that has cracked or collapsed, or swapping a tank water heater for a tankless unit are all jobs that require more planning than a repair but solve the underlying problem rather than extending it. The service page carries the full breakdown of what each of these involves.
Renovation projects, kitchen and bathroom updates, and new fixture installations are scheduled jobs where the plumbing work fits into a larger timeline. We coordinate with the project schedule, handle the rough-in and finish connections, and make sure the plumbing side is done before the walls close or the tile goes in. Garbage disposal installation, fixture swaps, and shutoff valve upgrades all fall here. We protect your floors and finishes while we work.
Mamaroneck is the focus, and we cover the surrounding communities in Westchester County as well. If you are in Larchmont, Rye, New Rochelle, Eastchester, or Pelham, the same service applies. The same response time, the same pricing process, the same work. Westchester County has a range of housing ages and property types, and the plumbing needs vary across the area. We handle all of it.
Reach out and we'll start at the source of the leak.
the page on plumbing repairs describes what happens once the work starts.
We can document what we found and what we recommended as part of the service call. If you need a written assessment for a real estate transaction, an insurance claim, or a property management record, let us know when you schedule and we will make sure the documentation is appropriate for that purpose.
Call us and describe what you are seeing. A problem that returns quickly after a repair usually means the underlying cause was not fully addressed the first time, or that there is a second issue contributing to the same symptom. We will assess what is happening and work from there.
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. 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.
We follow the layout of the building and use what is visible, including exposed pipe in basements, crawl spaces, and utility areas, to map the likely path of concealed runs. In some cases we use a camera or locating equipment to trace a line without opening the wall. We work out the route before recommending any invasive access.
We can assess the sewer line from the house out to the connection point, which is the section that belongs to the property. A camera inspection shows the interior condition of the pipe, including any root intrusion, cracks, or joint offsets that would affect the line's function. If you are buying a property in Mamaroneck and want to understand the condition of the underground plumbing before closing, call (475) 426-2879 and we will schedule an inspection.
We work within the schedule set by whoever is coordinating the project. If there is a general contractor or a project manager running the sequence, we coordinate with them directly. If you are managing the trades yourself, call us with the window you need and we will tell you whether we can meet it.
Yes. We work with landlords and building managers on drain calls, water heater replacements, fixture work across multiple units, and leak detection in shared walls and ceilings. We coordinate access with whoever manages the property and work around occupied units where the layout allows it. Call (475) 426-2879 and describe the building and the problem, and we will talk through what the job involves.
We clear the work area and take away any materials we brought in. If we opened a wall or floor section, we leave the opening ready for patching but do not typically do the finish work ourselves unless that was part of the agreed scope. We protect floors and finishes while we work, so the area around the repair should be in the same condition we found it.
Yes. A pre-purchase inspection is a reasonable step before committing to a home, particularly in areas with older housing stock where the condition of supply lines, drain lines, and the water heater may not be obvious from a general home inspection. Call (475) 426-2879 to schedule and we will assess the accessible plumbing and give you a clear picture of what is there.
Galvanized supply lines that have corroded from the inside out, sewer laterals with root intrusion or joint failure, and aging shutoff valves that will not fully close are among the most common issues in homes with older plumbing. Pressure that drops from room to room and rust-colored water at the tap are early signs that the supply lines are worth inspecting. A call and a few questions will help narrow down what is most likely going on before anyone comes out.
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.

| 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 Mamaroneck 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 | Mamaroneck 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 Mamaroneck'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 Mamaroneck 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 Mamaroneck 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 Westchester 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 Mamaroneck 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. |
