Al Kiewra Jr Plumbing & Heating has been showing up for Northport homeowners, landlords, and businesses since 1990. We are a family-run operation with deep roots in this community, and every call you make reaches someone who knows this area and cares about the work. Schedule it. We fix it. You're flowing.
Whether you have a burst pipe at midnight or a slow drain that has been bothering you for weeks, we are ready to help. Call us today at (631) 651-6924 to get a quote or book a service call.
If you've never hired a plumber before, the range of work we cover might surprise you. From a dripping kitchen faucet to a full sewer line repair, we handle the complete picture of residential and commercial plumbing. We work in older homes, newer construction, rental units, and commercial spaces throughout Suffolk County.
Slow drains and stubborn clogs are among the most common calls we get. A backed-up kitchen sink, a sluggish bathroom drain, or a main drain that keeps backing up are all problems we clear fast. We use drain snaking and hydro jetting to cut through grease, hair, mineral buildup, and tree roots. We're ready to get your drains running again.
Hearing a running toilet or a drip behind the wall? Hidden leaks waste water, raise your bills, and quietly damage your home. We use proven detection methods to find the source without tearing apart your walls unnecessarily. Once we locate the problem, we repair it cleanly and correctly.
No hot water is one of those problems that cannot wait. We repair and replace both tank and tankless water heaters, and we stock common units so we can often complete the job the same day. If your water heater is aging, running out of hot water quickly, or making unusual sounds, call us before it fails completely. Let us handle the plumbing and the permits.
A running toilet, a worn faucet, or a fixture that never quite worked right are small problems that add up fast. We handle toilet repair and replacement, faucet installation in kitchens and bathrooms, shower valve repair, and full fixture upgrades. The work is done right the first time by experienced plumbers who respect your home.
A garbage disposal that hums but does not grind, a shutoff valve that leaks when you try to close it, or water pressure so low the shower is barely usable are all jobs we handle routinely. We install and repair garbage disposals, replace shutoff valves, and diagnose pressure issues including pressure reducing valve replacement.
A sewer backup or a main line clog can shut down your whole home. We clear main line clogs, repair damaged sewer lines, and handle the full scope of sewer and main water line work. We keep your home dry and your water flowing.
Plumbing problems don't wait, and neither do we. A burst pipe, a flooded basement, or a water heater that has stopped working entirely are situations that need a real response, not a voicemail and a callback two days later. We offer same-day and after-hours service for genuine emergencies throughout Northport and the surrounding area.
When you call, you reach someone who can actually help. We will assess the situation, give you a straight answer on what needs to happen, and get a licensed plumber to your door as quickly as possible. Call today and we'll lock in your appointment.
Suffolk County has some of the oldest housing stock in the region. Homes built decades ago often have galvanized steel, lead, or aging cast-iron pipe that has simply reached the end of its useful life. Add a high water table, heavy nor'easter seasons, and winters that can freeze supply lines, and you have a region where certain plumbing jobs come up again and again. We have spent more than three decades handling exactly these situations.
Galvanized pipe corrodes from the inside out. Over time it restricts water flow, discolors your water, and eventually fails. Lead service lines present their own serious concerns. When a home's plumbing has reached that point, a full repipe with copper or PEX is the right answer. We assess the existing system, walk you through the scope of work, and complete the repipe with minimal disruption to your home. The result is clean water, reliable pressure, and plumbing that will last.
Cast-iron and clay sewer lines in older Suffolk County homes crack, corrode, and get infiltrated by roots over time. A sewer line that has deteriorated past the point of repair needs to come out and be replaced. We handle main line repairs and full sewer line replacements, and where conditions allow, we explore trenchless methods to reduce the impact on your yard.
The water table in many parts of Long Island sits close to the surface, and a serious nor'easter can push water into a basement fast. A properly installed and maintained sump pump is the first line of defense. We install new sump pumps, replace failed units, and address basement drainage issues before they turn into a water damage situation.
Cost is a real concern, and we do not hide the ball on pricing. When you call, we give you a straight estimate based on what the job actually involves. Licensed plumbers. Code-compliant work. Fair rates.
We stand behind every pipe and fixture we touch. If something is not right, we come back and make it right. That is the standard we have held since 1990, and it is not something we are willing to compromise. Call us at (631) 651-6924 to get an honest quote on any plumbing job, large or small.
Property managers trust us to keep their buildings running, and we take that responsibility seriously. A plumbing failure in a multi-unit building or a commercial space affects tenants, customers, and revenue. We understand that timeline and we respond accordingly.
We work with restaurants, office buildings, retail spaces, apartment complexes, and mixed-use properties throughout the area. Commercial drain cleaning, water heater replacement, pipe repair, and fixture installation are all part of what we do. We coordinate around your schedule, work cleanly, and communicate clearly so you are never left guessing about the status of a job. Call today and we'll lock in your appointment.
Beyond the everyday repairs, we handle a range of specialty plumbing work that comes up during renovations, seasonal maintenance, and property upgrades.
Gas line work is a regular part of our service. We install and repair the gas supply lines that run to water heaters, ranges, and outdoor grills. All gas line work is performed by licensed plumbers and done to code.
Outdoor plumbing gets overlooked until it fails. We repair and replace hose bibs and outdoor faucets, which is especially important after a hard winter when freeze damage is common. We also handle frozen pipe repair when the season calls for it.
For kitchen and bathroom renovations, we provide the rough-in plumbing, fixture installation, and connection work that makes a remodel come together correctly. We also install whole-house water filtration systems and backflow preventers for homeowners who want cleaner water and properly protected supply lines.
We're proud to be the plumbers this community calls first. Since 1990, we have built our reputation one job at a time in Northport and across the North Shore of Long Island. We are a family-run plumbing business, and that shows in how we work. You get a real person when you call, a plumber who shows up on time, and work you can count on.
A local plumber homeowners rely on is not built overnight. It takes years of showing up, doing the job right, and standing behind the work when questions come up. That is what we have done here for more than three decades.
We serve Northport and the surrounding communities throughout Suffolk County, including Centerport, Huntington, Cold Spring Harbor, Commack, East Northport, and Kings Park. If you are nearby and need a plumber, we are the call to make.
When you call, we ask a few questions about what you are seeing or experiencing so we can give you an accurate quote and show up prepared. A licensed plumber arrives at the scheduled time, assesses the problem, confirms the scope of work and the cost, and gets the repair or installation done. We test everything before we leave and make sure you understand what was done and why.

Shut off the water supply to the fixture immediately. The shutoff valve is typically located on the wall behind or beneath the toilet or fixture, and turning it clockwise will stop the flow. Once the water is off, call us at (631) 651-6924 and we will get a plumber to you as quickly as possible.

Yes. We are available every day from 8:30 AM to 9:30 PM, and we make same-day service available for genuine plumbing emergencies throughout Northport and the surrounding area. Burst pipes, major leaks, sewer backups, and no-hot-water situations are all calls we respond to urgently.
A general description of the problem goes a long way. Tell us what you are seeing or hearing, how long it has been happening, and where in the home the issue is located. If you know the age of the plumbing or the fixture involved, that is helpful too, though not required. We will ask follow-up questions to make sure we show up with the right materials and a realistic estimate.
The plumber will introduce themselves, take a look at the problem area, and walk you through what they find before any work begins. We confirm the scope and the cost with you before we start. Once the work is complete, we test the repair and clean up the work area before we leave.
Yes, and this is a significant part of what we do in the Northport area. Many homes throughout Suffolk County were built with galvanized steel, cast-iron, or early copper plumbing that has reached the end of its useful life. We are experienced with these systems and handle everything from targeted repairs to full whole-home repiping.
All work is performed by licensed plumbers and done to code. Where permits are required, we handle that process. You can have confidence that the finished work meets New York state and local requirements.

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.
