We are open every day from 5:30 AM to 9:00 PM, and the job is scoped and priced before a wrench comes out. Call us and a real person picks up.
Quick to arrive. Careful with your home. Clean when we leave.
This area has every kind of pipe and fixture in it, from century-old cast iron to modern PEX, and every plumbing problem that comes with that range. We work on homes of every age and size, multi-unit buildings, restaurants, offices, and commercial properties across Northport and the wider Suffolk County area. Whatever the job, we assess the situation, explain what we find, and confirm the price before any work begins.
A slow drain or a full blockage can shut down a kitchen, a bathroom, or an entire building. We clear kitchen drains, bathroom drains, floor drains, and main line clogs. The visit starts with a diagnosis to locate the blockage and identify the cause. For stubborn grease buildup or debris packed into older pipe, hydro jetting clears the line thoroughly without guesswork. The drain leaves the visit clear and flowing.
Some leaks announce themselves. Others hide behind walls or under slabs until the water bill climbs or a ceiling stains. We use pressure testing and electronic detection methods to find the source without tearing into a wall until we know exactly where to go. Once the leak is located, the repair is scoped and the price is confirmed before anything is opened up. Call and we'll get the water running right.
No hot water stops a household or a business fast. We repair and replace tank water heaters and tankless units, handle commercial water heater installation for restaurants and multi-unit buildings, and inspect units that are underperforming before recommending a replacement. If the unit can be repaired, we say so. If replacement makes more sense for the age and condition, we walk through the options and let you decide. We'll take care of the pipes from here.
A running toilet, a leaking faucet, or a dripping showerhead wastes water and adds up on a bill. We repair and replace toilets, install kitchen and bathroom faucets, swap out shower and bathtub fixtures, and handle full bathroom and kitchen fixture upgrades. Garbage disposal repair, installation, and replacement are part of the same visit when the work is in the same area.
Main line cleaning, sewer backup repair, sewer line inspection, water main repair, and water line installation are all part of what we handle. When a line is too far gone to clean, we replace it. Where the site and the line allow, trenchless methods keep disruption to the yard to a minimum. Fixtures and lines are left working before we go, and the scope is confirmed with you before digging or cutting begins.
Low water pressure has more than one cause. It can point to a partially closed shutoff valve, a failing pressure reducing valve, mineral buildup in the line, or pipe that has corroded from the inside over decades. We diagnose the cause, replace shutoff valves and pressure regulators where needed, and where the pipe itself is the problem, repiping is the lasting fix. For homes where pressure and water quality issues keep coming back, whole-home repiping addresses the root of it. That brings us to the work that comes up most often in this part of Long Island.
Plumbing a home right takes the right tools and a careful hand, and the housing stock here makes that especially true. Northport and the surrounding communities in Suffolk County carry some of the oldest homes on Long Island. That means galvanized pipe that has narrowed with corrosion, cast-iron drain stacks that have cracked under decades of freeze-thaw stress, and clay sewer lines that tree roots have found their way into. Add a high water table and the wet basements that come with it, and the work that comes up most often here is not hard to predict.
Galvanized steel pipe was the standard for water supply lines in homes built before copper became common, and a large share of Northport's older housing still has it. Galvanized pipe corrodes from the inside out. The result is reduced water pressure, discolored water, and pipe that eventually fails at a joint or along a run. Coastal humidity accelerates the process. We assess the existing pipe, walk through material options including copper and PEX, confirm the scope, and price the job before work begins. The job is scoped and priced before a wrench comes out, so there are no decisions made under pressure.
Older clay and cast-iron sewer lines in Suffolk County are well past their designed service life in many neighborhoods. Root intrusion is common where mature trees line the property, and the freeze-thaw cycles that Long Island winters bring stress joints that were already weakening. We inspect the line, identify what is failing and where, and replace the section or the full run as needed. Where conditions allow, trenchless replacement keeps the yard largely intact. Let us handle the plumbing and the permits.
Long Island's water table runs high, and basements in Northport and the communities around it collect water when the ground is saturated. A nor'easter or a stretch of heavy spring rain can overwhelm a sump pump that is undersized or past its working life. We install, repair, and replace sump pumps, and we service the drainage lines that carry water away from the pump. If the drainage line is blocked or pitched incorrectly, the pump cannot do its job regardless of how new it is.
Your time matters, so we keep the plumbing job moving, and that applies as much to a restaurant kitchen or an apartment building as it does to a single-family home. Property managers, building owners, and commercial tenants across Suffolk County deal with plumbing problems that cannot wait for a weekday window. We handle commercial drain cleaning, commercial water heater installation, pipe repair, leak detection, and backflow prevention work for offices, restaurants, and multi-unit properties. The job is scoped before work starts, the price is explained up front, and we are available every day from 5:30 AM to 9:00 PM. We'll sort the plumbing and clean up after.
When the job is done, we leave your home clean and dry, but getting there starts with picking up the phone. A burst pipe, a major leak, a sewer backup, or a water heater that has stopped working entirely are all situations where waiting is not an option. We take emergency calls every day from 5:30 AM to 9:00 PM. When you call, the job is scoped on the call, the price is confirmed, and the visit is scheduled. There is no guessing about what comes next.
Pick the date. We do the plumbing. We clean up after.
Plumbing a home right takes the right tools and a careful hand, and knowing what it costs before the work starts is part of that. When you call, you get a rate on the phone. The price is confirmed when the job is scoped, before anything is scheduled or started. If a permit is required for the work, we tell you. If the choice is between repairing what is there and replacing it, we explain both options and what each involves.
We tell you if a permit is needed. We explain repair or replace. You make the choice.
We work throughout Northport and the communities that surround it in Suffolk County. That includes Centerport, Huntington, Cold Spring Harbor, East Northport, Greenlawn, Commack, Kings Park, and Smithtown. Whether the property is a single-family home, a rental unit, or a commercial building, the same process applies: call to describe the problem, get the scope and price on the call, and schedule the visit. We'll take care of the pipes from here.
Call (631) 651-6924 and describe what you are dealing with.
We scope the job on the call, confirm the price, and schedule the visit before anything else happens. You do not need to have all the answers ready before you call. A few details about the symptom and the location in the house are usually enough to get started.
We take emergency calls every day from 5:30 AM to 9:00 PM, including weekends.
If a pipe has burst, a water heater has stopped working, or a sewer line is backing up into the house, call (631) 651-6924 right away.
We scope the situation on the call and confirm what the visit involves before anyone is dispatched. The price is settled before the visit is scheduled, even on urgent calls.
Shut off the water supply to the affected fixture or, if the leak is major, turn off the main shutoff valve where the water line enters the house.
Then call (631) 651-6924 so we can scope the damage and get the repair scheduled.
Cutting the water supply stops the flooding while we work out what comes next. We will walk you through the shutoff location on the call if you are not sure where it is.
The price is confirmed on the call based on what you describe and what the job is expected to involve. If the work on-site turns out to differ from what was discussed, we explain what changed and confirm the updated scope before proceeding. We do not start additional work without your agreement. The goal is that nothing on the invoice surprises you.
It starts with a call where we ask about the problem and scope the job. Once the price is confirmed, the visit is scheduled. When the plumber arrives, the situation is assessed, the repair or installation is carried out, and the work area is cleaned before we leave. Fixtures and lines are left working before we go.
We are open every day from 5:30 AM to 9:00 PM, which gives a wide window for scheduling. Early morning slots are available for those who need the work done before the day starts.
Call (631) 651-6924 and ask what is open on the schedule. We will find a time that works for your situation.
Lead times depend on the type of job and what is on the schedule when you call. Smaller repairs and drain calls often get scheduled sooner than larger jobs like a full repipe. For urgent situations, call and ask directly what is available. Short-notice work does come up, and asking on the call is the quickest way to learn what the schedule allows.
A single visit can cover drain cleaning, leak repair, toilet or faucet replacement, shutoff valve work, water heater assessment, and related fixture work in the same area. We handle what the job calls for and confirm the scope before starting. If the visit reveals a larger issue, we explain what we found and what the options are. Nothing gets added to the job without your approval.

We handle the full range of residential and commercial plumbing work across Northport and the surrounding Suffolk County area. Every job starts with a clear scope on the call so you know the price before anything is scheduled. The table below covers what each service includes, who it fits, and what is worth knowing before you call. If you have a question the table does not answer, call us and we will work through it with you.
| Type of Job | What the Job Covers | Recommended For | Good to Know |
|---|---|---|---|
| Drain Cleaning & Clog Removal | Kitchen and bathroom drain clearingMain line backupsHydro jetting for stubborn buildupRoot intrusion clearing | Recurring slow drains or a backup affecting multiple fixtures | Hydro jetting reaches buildup that a standard snake cannot, and it is often the right call for older cast-iron lines that have accumulated grease and scale over decades. |
| Leak Detection & Repair | Tracing the source before any pipe is openedBurst pipe and supply line repairMain water line repair at the house entryWall and under-floor leak assessment | Any unexplained water bill increase or visible water staining | We find the cause before recommending a repair. A hidden leak left unaddressed can affect the surrounding structure over time, so early detection keeps the scope of the repair smaller. |
| Whole-Home Repiping | Galvanized, lead, and failing copper pipe replacementPEX or copper supply system installationSection-by-section work to limit water shutoff timePermit coordination | Older homes with recurring leaks, discolored water, or restricted flow throughout | Galvanized pipe corrodes from the inside out and narrows over time. Repeated repairs on the same line are a sign the pipe itself has reached the end of its useful life, and repiping resolves the pressure and leak issues at the source. |
| Sump Pump & Basement Drainage | Sump pump installation and replacementFloat switch and cycling diagnosisDischarge line inspection and repairPit and drain line service | Basements that take on water during storms or a pump that is not cycling correctly | Long Island's water table runs close to the surface in many areas. A pump that ran during the last storm and could not keep up may be undersized, or the discharge line may be blocked or pitched incorrectly. |
| Water Heater Repair & ReplacementMost Popular | Tank water heater diagnosis and repairFull tank replacement with removal of old unitTankless water heater installation and repairGas line and water line connections | A water heater that is underperforming, leaking, or at the end of its useful life | Tank units typically last eight to twelve years. If yours is producing discolored water or running out faster than it used to, it is worth a call before a failure leaves you without hot water. |
| Sewer Line Replacement | Full sewer line replacement from house to street connectionTrenchless pipe replacement where conditions allowCamera inspection before and afterPermit coordination | A sewer line with collapse, offset joints, or repeated root intrusion that clearing alone cannot fix | Where the site allows it, trenchless methods reduce excavation and limit disruption to the yard. We confirm which approach fits your property before the job starts. |
| Cast-Iron Drain Stack Replacement | Deteriorating cast-iron stack removalPVC or ABS replacement installationConnection to existing branch drainsInspection access where needed | Older multi-story homes with recurring drain odors, slow drains, or visible pipe deterioration | Cast-iron drain stacks in homes built before the 1970s can corrode through from the inside. Replacing the stack resolves recurring drain issues that cleaning alone cannot fix. |
| Emergency Plumbing | Burst pipe responseMajor leak containment and repairLoss of hot waterSewer backup affecting multiple drains | Any plumbing failure that cannot wait for a scheduled appointment | We are open every day from 5:30 AM to 9:00 PM. When you call, we scope the situation on the phone and confirm the price before scheduling so there is no uncertainty about what happens next. |
| Water Pressure & Shutoff Valve Repair | Pressure reducing valve diagnosis and replacementShutoff valve repair and replacementSupply line pressure testingWhole-house pressure assessment | Low pressure at multiple fixtures or a shutoff valve that will not fully close | In homes with galvanized supply lines, mineral buildup inside the pipe is often the root cause of pressure loss. Replacing the valve alone may not restore full pressure if the line itself is restricted. |
| Lead Service Line Replacement | Lead pipe identification and removalReplacement from the meter to the houseConnection to existing supply systemPermit coordination | Homes with original service lines that have not been replaced | There is no safe level of lead in drinking water. Many older Northport homes still carry original lead service lines. Replacement eliminates the source rather than relying on filtration to manage it. |
| Toilet Repair & Installation | Running toilet diagnosis and repairFlapper, fill valve, and flush valve replacementFull toilet replacementWax ring and floor flange service | A toilet that runs constantly, rocks, or needs full replacement | A running toilet can waste a significant amount of water before the sound becomes obvious. Most repairs are completed in a single visit. |
| Sewer & Main Line Service | Camera inspection of the sewer lineRoot intrusion clearingSewer line repair and replacementTrenchless methods where the site allows | Slow drains throughout the house or sewage backing up into lower fixtures | Clay and cast-iron sewer lines in established Suffolk County neighborhoods are prone to joint separation and root intrusion. A camera scope tells us exactly what we are dealing with before any excavation starts. |
| Faucet & Fixture Installation | Faucet repair and replacementSink and shower fixture installationGarbage disposal repair and replacementSupply line and shut-off valve replacement | Bathroom or kitchen upgrades and dripping or failing fixtures | If you are supplying your own fixture, let us know the model on the call so we can confirm the connections match what is already in the wall. |
Call (631) 651-6924 and we will scope your job on the call, give you a clear price, and tell you exactly what to expect from the visit.
