Hearing a running toilet or a drip behind the wall? Whether you own a single-family home in Northport, manage a rental property in Huntington, or oversee a commercial building anywhere in Suffolk County, the plumbing problems you face are real and they need a real solution. We handle the full range of residential and commercial plumbing work: drain cleaning and clog removal, leak detection and repair, water heater service, toilet and faucet installation, sewer and main line work, and whole-home repiping.
Property managers trust us to keep their buildings running because we show up on schedule, explain what we find, and complete the work cleanly. Homeowners come back to us because we treat every house the way we would treat our own. We work across all property types, from older Cape Cods and colonials to newer construction and multi-unit buildings, and we bring the same level of care to every one of them. As a family-run plumbing business, we understand that our name stays on the work long after we leave your driveway.
We keep your home dry and your water flowing.
Al Kiewra Jr started this business in 1990 with a single truck, a set of tools, and a straightforward idea: do the work right, charge a fair price, and treat every customer the way you would want to be treated yourself. What began as a one-man operation serving Northport and the immediate surrounding area has grown steadily over three and a half decades into a trusted name across Suffolk County. The business has stayed family-run by design, because that structure keeps us accountable in a way that a larger operation simply cannot match.
Thirty-six years of local plumbing work means we know the housing stock here. We have worked inside the older homes with galvanized and cast-iron plumbing that was original to the 1950s and 1960s, the mid-century ranches and split-levels, the newer builds with PEX supply lines, and the commercial properties scattered throughout the county. We understand the pipe materials, the common failure points, and the code requirements that apply here in New York. When we walk into a home, we are not guessing. We are drawing on decades of hands-on experience. Our experienced plumbers who respect your home bring that background to every job, and it shows in the quality of the finished work.
Northport is our home base, and Suffolk County is our backyard. We regularly serve homeowners and businesses in Centerport, Huntington, East Northport, Cold Spring Harbor, Commack, Kings Park, and the surrounding communities. If you are nearby and need a plumber, give us a call and we will let you know if we can get to you.
A slow drain is easy to ignore until it stops draining entirely. We clear clogged and slow-moving drains in kitchens, bathrooms, laundry rooms, and utility spaces, and we clean main drain lines when the problem runs deeper than a single fixture. For stubborn blockages and buildup in main lines, we use hydro jetting to clear the line thoroughly rather than just punch through the clog. Commercial properties with high-use drain systems benefit from the same service. When you call us about a drain, we diagnose the cause, not just the symptom, so the problem does not come back two weeks later.
Plumbing problems don't wait, and neither do we, especially when a hidden leak is doing damage behind a wall or under a floor. Water leak detection involves more than looking for wet spots. We use pressure testing and inspection to locate leaks that are not visible to the eye, including leaks in water supply lines and areas that are difficult to access. Catching a leak early almost always costs less than repairing the water damage it causes if it goes undetected. We also handle water pressure diagnostics and shutoff valve repair, because low pressure and a valve that will not close fully are often connected to the same underlying issue.
We're ready to get your drains running again.
No hot water is one of the most disruptive plumbing problems a household or business can face. We service and replace both tank and tankless water heaters for residential and commercial customers. If your unit is failing, making noise, or simply not keeping up with demand, we diagnose the problem and give you an honest assessment of whether repair or replacement makes more sense given the age and condition of the unit. Tankless water heater installation is an option for homeowners looking to improve efficiency and free up space. We handle both gas and electric units. As a local plumber homeowners rely on, we carry the parts and equipment to handle most water heater calls without a second trip.
A running toilet, a dripping faucet, or a fixture that has seen better days are the kinds of problems that seem minor until they are not. We repair and replace toilets, install new faucets in kitchens and bathrooms, service shower and bathtub fixtures, and replace outdoor hose bibs and spigots that have cracked or corroded. Garbage disposal installation and repair falls in this category as well. If you are working through a bathroom or kitchen remodel, we handle the rough-in plumbing and fixture installation so the finished product is done to code and functions the way it should.
Call today and we'll lock in your appointment.
A sewer backup or a blocked main line is not a problem you can put off. We clear sewer line blockages, repair damaged sections of pipe, and replace lines that have deteriorated beyond the point of repair. Sewer line inspection is part of our diagnostic process when the cause of a backup is not immediately clear. We speak only to the line itself, from the house out to the connection point, and we have the equipment to handle main line work efficiently. Trenchless repair methods are available when the location and condition of the line make that approach practical, which can reduce disruption to your yard and landscaping.
Older homes throughout Suffolk County were built with galvanized steel or early copper plumbing that is now reaching the end of its useful life. When pipes corrode from the inside, the signs show up as rusty water, recurring leaks at different points in the system, or low water pressure throughout the house. When those symptoms appear together, repiping is often the most cost-effective long-term solution rather than continuing to patch individual failures.
We perform whole-house repiping using copper or PEX depending on the application and the homeowner's preference. The work involves replacing the supply lines throughout the home, restoring full pressure and clean water delivery to every fixture. We also handle pressure reducing valve replacement and related pressure repair work as part of the same service when needed. Backflow preventer installation and gas line service are additional specialty jobs we take on for both residential and commercial customers. We stand behind every pipe and fixture we touch, and repiping work is no exception. When we repipe a home, we do it to last.
Let us handle the plumbing and the permits.
If you've never hired a plumber before, a plumbing emergency can feel overwhelming. Burst pipes, major leaks, and no-hot-water calls are not situations where you want to wait days for an appointment. We offer 24-hour emergency plumbing service and same-day scheduling options for urgent calls. When you reach us, you speak with someone who understands the problem and can tell you what to expect before we arrive.
Common emergency calls we respond to include burst and broken pipes, sudden water leaks, sewer backups, and water heaters that have failed completely. If you are not sure whether your situation qualifies as an emergency, call us anyway. We will ask a few questions and help you figure out the right next step. Our goal is to get the problem under control quickly and leave you with a repair that holds.
Schedule it. We fix it. You're flowing.
One of the most common concerns homeowners have before calling a plumber is not knowing what the job will cost. We address that directly. When you call for a quote, we ask about the problem, explain what the work typically involves, and give you a clear picture of what to expect before anyone shows up at your door. If the scope of work changes once we are on site, we communicate that before we proceed. No surprise charges at the end of the job.
What affects the cost of a plumbing job depends on the type of work, the materials required, the condition of the existing plumbing, and how accessible the problem area is. We explain all of that in plain language. The work is performed by licensed plumbers, which means it is done to code and done correctly the first time. We are not the cheapest option in every case, but we are consistently honest about what a job costs and why.
Licensed plumbers. Code-compliant work. Fair rates.
We keep your home dry and your water flowing.
The business started in 1990 as a one-person operation with a straightforward approach: do the work right, charge a fair price, and treat every customer the way you would want to be treated. That approach has not changed over 36 years, and staying family-run has kept us accountable in a way that a larger operation cannot replicate. The reputation we have built in Northport and across Suffolk County is the result of showing up consistently and standing behind the work.
Before we start, we walk you through what we found and confirm the scope and cost of the work. If something unexpected comes up once we are into the job, we stop and explain the situation before proceeding. We do not make decisions on your behalf without your input, and we make sure you understand what was done before we leave.
We stand behind every pipe and fixture we touch. If something is not right after we have completed a job, call us and we will come back and make it right. That standard has been in place since 1990 and is not something we compromise on.
Where a permit is required, we handle that process as part of the job. All work is performed by licensed plumbers and done to code, so the finished installation meets New York state and local requirements. We manage the paperwork so you do not have to.
Very familiar. We have been working inside the older homes of Northport and the surrounding communities for 36 years, and we know the pipe materials, the common failure points, and the code requirements that apply here. Galvanized steel, cast-iron drain stacks, clay sewer lines, and early copper systems are not unusual to us. We draw on decades of hands-on experience rather than guessing at what we find.
Yes. Proper tools are not optional when the work needs to be done right and done to last. We carry the equipment to handle the full range of residential and commercial plumbing work, including hydro jetting for stubborn drain blockages and the inspection tools needed to locate hidden leaks and assess sewer lines before recommending a course of action.
When you call during our operating hours, 8:30 AM to 9:30 PM every day, you reach someone who can help right away. We do not put you on hold for a callback that arrives days later. For urgent situations, we work to get a plumber to you the same day. Call us at (631) 651-6924 and we will give you an honest answer on timing.
Al Kiewra Jr Plumbing & Heating has been part of this community for 36 years, and we intend to be here for the next 36. Whether you need a drain cleared today, a water heater replaced this week, or a full repiping project planned for next month, we are ready to help. We are locally owned and personally accountable for every job we take on. When you call, you reach someone who knows Northport, knows Suffolk County, and knows what it takes to get your plumbing working the way it should.
Call (631) 651-6924 to request a quote or schedule service. We are available around the clock for emergencies and offer same-day appointments when your situation cannot wait.
Schedule it. We fix it. You're flowing.

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 to twelve years old and showing problems is usually a better candidate for replacement than repair. Signs like rusty water, a unit that runs out of hot water quickly, rumbling or popping sounds, or visible corrosion around the tank all point toward replacement. If the unit is younger and the issue is a failed element, thermostat, or valve, a repair often makes sense. When you call, we ask a few questions and give you a straight answer on which direction is the better value.
What is the difference between a tank and a tankless water heater?
A tank water heater stores a set volume of hot water and keeps it ready. A tankless unit heats water on demand as it flows through. Tankless units take up less space and do not run out of stored hot water, but they have a higher upfront cost and may require upgrades to the gas line or electrical supply. Tank units are simpler and less expensive to install. We can walk you through both options based on your household size, usage patterns, and budget so you make the right call for your home.
What causes drains to clog, and when does snaking not solve the problem?
Most household drain clogs come from grease buildup in kitchen lines, hair and soap in bathroom drains, or debris that accumulates over time. Snaking cuts through or pulls out a localized blockage, and it works well for most routine clogs. When the problem keeps coming back, or when multiple drains in the home are slow at the same time, the issue is usually further down in the main line. Tree roots, grease accumulation deep in the line, or a partially collapsed pipe are situations where hydro jetting or a camera inspection gives us a clearer picture of what is actually going on.
Same-Day and Emergency Availability
We are available every day from 8:30 AM to 9:30 PM for urgent situations throughout Northport and the surrounding area. When a burst pipe or sewer backup cannot wait, we respond the same day.
How do you find a hidden leak without tearing up the walls?
We start by narrowing down the location using pressure testing and a careful look at where moisture or damage is showing up. From there we use detection methods that let us identify the source without opening walls unnecessarily. Once we have confirmed the location, we make a targeted access point, complete the repair, and restore the area. The goal is always to do the least amount of disruption needed to fix the problem correctly.
How do I know if my home needs repiping versus targeted repairs?
If your home has galvanized steel pipe that is corroding from the inside, you may notice discolored water, reduced pressure at multiple fixtures, or recurring leaks at different spots over a short period. When the pipe itself has reached the end of its life, patching one section only shifts the problem to the next weak point. A full repipe with copper or PEX addresses the root cause and gives you clean water and reliable pressure for decades. We assess the existing system and give you an honest recommendation based on what we actually find.
What are the signs of a sewer or main line problem?
The most common signs are multiple slow drains throughout the home, gurgling sounds from toilets or drains when water runs elsewhere, sewage odors inside or around the foundation, or water backing up into a tub or floor drain when you flush a toilet. Any one of these can point to a main line blockage or a more serious line failure. Because the main line serves every drain in the home, a problem there affects everything. We recommend calling sooner rather than later when these signs appear.
Experienced With Older and Newer Homes
Suffolk County has some of the oldest housing stock on Long Island, and we have spent more than three decades working in homes built with galvanized steel, cast-iron, and early copper systems. We know what to look for and how to fix it right.
How do tree roots damage a sewer line, and what does the repair involve?
Tree roots naturally seek out moisture, and older clay or cast-iron sewer lines develop small cracks and joint gaps over time that roots find and grow into. Once inside the line, roots spread and eventually block flow or cause the pipe to collapse. We clear root intrusions using mechanical cutting or hydro jetting and then inspect the line to assess how much damage has been done. If the line has deteriorated beyond clearing, we discuss repair or replacement options. Where conditions allow, trenchless methods can reduce the impact on your yard.
What causes low water pressure, and can it be fixed without a major repair?
Low pressure has several possible causes. A failing pressure reducing valve is one of the most common and is a straightforward fix. Corroded or partially blocked galvanized pipe restricts flow from the inside and may point toward a broader repiping conversation. A partially closed shutoff valve or a supply line issue can also be the culprit. We diagnose the source before recommending a solution, and in many cases the fix is simpler than homeowners expect.
Workmanship We Stand Behind
We stand behind every pipe and fixture we touch. If something is not right after we leave, we come back and make it right. That standard has not changed since 1990.
What should I do if a pipe bursts or a major leak starts?
Shut off the water supply to the affected area immediately. If you cannot isolate it to one fixture or section, shut off the main water supply to the house. The main shutoff is typically near the water meter or where the supply line enters the home. Once the water is off, call us at (631) 651-6924 and we will get a plumber to you as quickly as possible. Do not attempt to open walls or disconnect pipe fittings under pressure. Getting the water off first limits the damage while help is on the way.
Do I need to be home when the plumber arrives?
For most jobs, yes. We need access to the problem area and we confirm the scope and cost with you before any work begins. If you are a property manager or landlord coordinating access for a tenant, we can work with you on the logistics. Just let us know the situation when you call and we will make sure the visit goes smoothly for everyone involved.
How does sump pump failure lead to basement flooding, and what are the warning signs?
A sump pump sits in a pit at the lowest point of the basement and pumps groundwater away from the foundation before it can rise into the living space. When it fails, water that would normally be redirected has nowhere to go. Warning signs include a pump that runs constantly without cycling off, one that makes unusual grinding or rattling sounds, or one that does not activate at all when water enters the pit. A pump that is more than seven to ten years old is worth evaluating before the next heavy rain season. We install new pumps and replace failed units, and we can assess your basement drainage situation at the same time.
Every home and every plumbing situation is a little different. Call us at (631) 651-6924 and we will give you a straight answer on what the job involves and what it will cost.
