If you've never hired a plumber before, it can feel uncertain knowing who to call and whether you'll get a fair shake. Al Kiewra Jr Plumbing & Heating has been serving Northport and the surrounding Suffolk County area since 1990, and as a family-run plumbing business, we treat every job the way we'd want our own home treated. Homeowners, landlords, and property managers across the area have counted on us for straightforward plumbing repair and installation for over three decades.
Licensed plumbers. Code-compliant work. Fair rates.
Whether you need a leaking pipe fixed today or a full plumbing upgrade planned for next month, we're here to help. Call (631) 651-6924 to schedule or get a quote.
Plumbing problems don't wait, and neither do we, so we've built our schedule around getting to you quickly with the tools and experience to handle the full range of residential and commercial plumbing work. From a dripping faucet to a sewer backup, we handle it all. Our experienced plumbers who respect your home show up ready to diagnose the problem, explain the fix, and get the work done right.
We keep your home dry and your water flowing.
A slow drain is an early warning. A completely blocked line is an emergency. We clear clogged sinks, toilets, tub drains, and kitchen lines using the right tools for the job, including hydro jetting for stubborn or recurring blockages. We also handle main line cleaning and sewer backup repair when the problem runs deeper than a simple clog.
A leak behind the wall or under the floor can do serious damage before you ever notice the water. We locate hidden leaks, repair or replace damaged pipe sections, and handle burst pipe emergencies when they happen. Under-sink leaks, water line failures, and supply line issues all fall within what we handle every day.
No hot water is one of those problems that brings everything to a halt. We repair and replace both tank and tankless water heaters, and we install new units with the code-compliant connections that keep everything safe and up to standard. Work is performed by licensed plumbers who know the local requirements.
A running toilet wastes water and money. A dripping faucet does the same. We repair and replace toilets, install new faucets and fixtures, clear shower and bathtub drains, and handle garbage disposal installation and replacement. Outdoor faucets and hose bibs are part of the picture too, especially heading into and out of winter.
Low water pressure is frustrating and often a sign of a larger issue. We diagnose the cause, whether it's a partially closed shutoff valve, a corroded line, or a pressure regulator that's given out, and we make the repair or replacement to restore proper flow throughout your home or building.
Hearing a running toilet or a drip behind the wall? Those are the calls we take seriously, because small problems can turn into costly ones fast. Burst pipes, sewer backups, major leaks, and no-hot-water situations all qualify as plumbing emergencies, and we make same-day and after-hours service available for exactly these moments.
We're a local plumber homeowners rely on when things go wrong at the worst time. You reach someone who knows the area, knows the housing stock, and can get to you without delay.
We're proud to be the plumbers this community calls first.
If you're dealing with an active plumbing failure, don't wait it out. Call today and we'll lock in your appointment. Reach us at (631) 651-6924.
Property managers trust us to keep their buildings running, and a big part of that trust comes from understanding what the local housing stock actually demands. Northport and the surrounding Suffolk County communities are home to some genuinely old construction. Galvanized pipe, aging cast-iron drain stacks, clay sewer lines, and high water tables are not abstract concerns here. They show up on job sites regularly. The services below reflect the work that comes up most often in this area and why it matters.
We stand behind every pipe and fixture we touch.
Older homes in the area were commonly built with galvanized steel pipe, which corrodes from the inside out over time. The result is reduced water pressure, discolored water, and eventually leaks that seem to come from everywhere at once. Repiping replaces the aging supply lines throughout the home with modern materials that restore full pressure and eliminate the cycle of recurring repairs. We assess the existing system, walk you through the scope of the work, and complete the job with minimal disruption to your household. Lead service line replacement is part of this work when it's needed.
The established neighborhoods of Suffolk County are full of clay and cast-iron sewer lines that have been in the ground for fifty years or more. Tree root intrusion is a common problem, and lines that have cracked or collapsed can't be cleared with a cable alone. We inspect the line, identify the damage, and replace what needs to come out. Where conditions allow, trenchless methods reduce the disruption to your yard. If you're dealing with repeated sewer backups or slow drains that don't respond to cleaning, a line inspection is the right next step. Cast-iron drain stack replacement is a related job we handle when interior stacks show the same age-related deterioration.
The water table across much of the Northport area runs high, and nor'easters push that water further. A sump pump that fails during a storm can mean a flooded basement within hours. We install, repair, and replace sump pumps, and we service the drainage systems that feed them. If your pump is running constantly, cycling oddly, or simply old enough to be unreliable, a service call before the next storm is the right move.
Let us handle the plumbing and the permits.
We work with all types of customers, and we adjust to what each situation actually calls for. On the residential side, that means showing up on time, explaining what we found, quoting the work clearly, and leaving the space as we found it. Homeowners don't want surprises on the bill or damage to their floors and walls. Neither do we.
For landlords, property managers, and commercial accounts, the priorities shift slightly. Reliable scheduling, work that holds up over time, and code-compliant installations that won't create problems at inspection all matter more when you're managing multiple units or a commercial space. We handle plumbing for renovations and remodels as well, coordinating the rough-in and finish work that a project requires.
We're ready to get your drains running again.
Pricing is a fair thing to ask about, and we don't make it complicated. What a job costs depends on what the job actually involves. A simple faucet swap is a different conversation than a whole-home repipe. When you call, describe what you're seeing or what you need done, and we'll give you an accurate quote based on the real scope of the work.
We've been doing this since 1990, and our rates reflect the value of experience without padding the bill for work that doesn't need to be done.
Affordable rates. Flexible timing. Sound pipes.

Common signs include water that takes longer than usual to heat up, a unit that runs out of hot water faster than it used to, discolored or rusty water at the hot tap, unusual rumbling or popping sounds from the tank, and visible corrosion or moisture around the base of the unit. Age is also a factor. If your tank water heater is more than ten to twelve years old and showing any of these signs, a replacement is often the more cost-effective path. Call us and we can assess whether repair or replacement makes more sense given the condition of your unit.
A persistent sewer smell indoors typically points to a dry or damaged P-trap, a cracked drain line, or a venting problem that is allowing sewer gas to enter the living space. In older Suffolk County homes, deteriorated cast-iron or clay sewer lines can also be a source. We diagnose the cause rather than masking the symptom, because sewer gas is not something to ignore.
When a standard drain snake does not fully resolve a blockage, hydro jetting is the next step. Hydro jetting uses high-pressure water to cut through grease buildup, mineral scale, and root intrusion that a cable cannot remove cleanly. It is particularly effective for main drain lines and commercial drain systems that see heavy use. After jetting, the line is clear rather than just punctured through.
We look at the age and material of the existing plumbing, the number and location of recent failures, the condition of the pipe walls where we can inspect them, and the overall water pressure and water quality in the home. A single leak in an otherwise sound system usually calls for a targeted repair. When leaks are occurring at multiple points, water pressure has dropped throughout the home, or the water is discolored from internal corrosion, a full repipe is the more practical long-term solution.
The timeline depends on the size of the home, the number of fixtures, and the condition of the existing plumbing. A typical single-family home repipe takes one to three days. We walk you through the expected timeline before we start so you can plan accordingly, and we work to minimize disruption to your household during the process.
For most plumbing repairs, yes, the water supply to the affected area or to the whole home will need to be off for some portion of the job. We minimize the time the water is off and restore service as quickly as the work allows. We will let you know in advance what to expect so you can plan around it.
We use pressure testing and inspection methods to isolate the section of pipe where the leak is occurring, then narrow it down from there. The goal is to find the source with as little disruption to walls and flooring as possible. Once we locate the leak, we repair or replace the affected section and test the repair before closing anything up.
After any pipe repair, water heater installation, or fixture connection, we run the system and check all connections under pressure before we consider the job complete. We look for drips, check shutoff valve operation, and confirm that flow and pressure are correct at the affected fixtures. We do not pack up until we are confident the work is holding.
For most jobs, yes, we prefer that an adult be present so we can walk through the problem together, confirm the scope of work, and review the finished job before we leave. If being home is not possible, we can discuss access arrangements when you schedule. Call (631) 651-6924 and we will work out the details.
Clear the area under sinks that are involved in the job, move anything stored in front of or around the water heater, and make sure the path to the main water shutoff is accessible. If the work involves a basement drain or sump pump, clear the area around it as well. A little preparation on your end helps us get started without delay.
The most common reason is that the actual condition of the plumbing turns out to be worse than what was visible at the time of the estimate. Corroded fittings, deteriorated pipe sections behind walls, or a clog that turns out to be a collapsed line rather than a simple blockage can all add to the scope. We communicate any change in scope before we proceed with additional work, so there are no surprise charges at the end of the job.
We disconnect and remove the old unit, install the new disposal with the correct mounting hardware and drain connections, and test it before we leave. Most garbage disposal replacements take under an hour. If the existing drain configuration needs adjustment to fit the new unit, that adds a small amount of time. We carry common disposal models so we can often complete the job in a single visit.
If your sump pump is running constantly, cycling on and off rapidly, making unusual sounds, or simply not activating when water enters the pit, those are signs the unit is failing. Given the high water table in many parts of the Northport area and the potential for rapid basement flooding during a nor'easter, a failing sump pump is not something to delay on. Call us and we will assess whether repair or replacement is the right call.
Sewer line replacement involves excavating to reach the damaged section of pipe, removing the old line, and installing new pipe with proper slope and connections. Where conditions allow, trenchless methods reduce the amount of digging required and limit the impact on landscaping. We assess the location and condition of the line before recommending an approach, and we walk you through what the work will involve before we start.

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.
