Quick answer: Because the units above and below share the same vertical drain. When a kitchen or bathroom stack clogs, water from upper floors has nowhere to go and comes up in the lowest fixture on that line, usually the ground floor or basement unit. We clear the stack from the top or from a cleanout, then camera it to see what caused the blockage.

Plumbing in an apartment building is one connected system. A kitchen stack serves six units stacked on top of each other. A single main carries every drain in the building to the street. A bank of water heaters supplies hot water to dozens of households at once. When one piece fails, the problem rarely stays in one apartment. Fullerton Plumbing works on apartment buildings, multifamily homes, mixed use buildings with retail below and residences above, and HOA communities across New York, and we treat the building as a system rather than a list of separate calls.

We clear and jet stacked drain lines, open shared building mains, repair and replace multiple water heaters, and track down leaks that travel between floors. We schedule around tenants, give notice windows you can pass along, and work in occupied units with drop cloths and shoe covers. Owners, landlords and HOA boards get an upfront quote before work starts and a plain explanation of what we found. Fullerton is fully insured, has served New York for 7 years, and holds a 4.9 star rating on Google from customers who mention clean work and fair pricing.

For buildings with recurring backups, we set up a jetting schedule for the stacks and main that matches how the building is used. Older buildings with cast iron stacks and heavy kitchen use often need attention once or twice a year. Newer buildings may need far less. We camera the lines first so the schedule is based on what is actually inside the pipe, not a guess. That approach usually costs less than paying for emergency calls every time a ground floor unit floods on a Sunday night.

How it works

Our Apartment and Multifamily Plumbing Process

Call Us Any Hour

Call 24/7 and tell us which units are affected and where. We ask a few questions to narrow down whether the problem is a single fixture, a stack or the building main, then dispatch the nearest available technician.

Find the Shared Cause

We check the units involved, open cleanouts and run a camera when needed to see where the line is blocked or damaged. You get an upfront quote before work starts, with options when a temporary fix and a permanent repair both make sense.

Coordinate With Tenants

We plan access windows with you so you can notify tenants, limit water shutoffs to the smallest possible area and keep the time short. When we need to enter several units, we move through them in order and keep each one clean.

Repair and Plan Ahead

We complete the repair, test the line from the top floor down and clean up. Then we explain what caused the problem and, if it is likely to return, recommend a jetting or inspection schedule for that stack or main.

New York plumbing

Multifamily Plumbing in New York Buildings

New York has some of the oldest apartment housing in the country. Brick walkups in Albany, Troy and Schenectady, two and three family homes across Buffalo and Rochester, and prewar buildings throughout New York City often still run on original cast iron stacks and clay or cast iron laterals. Over decades those pipes scale up inside, crack at joints and catch grease from every kitchen above. Mixed use buildings add a restaurant or shop on the ground floor that sends its own load into the same main. Winter adds frozen pipes in unheated stairwells, basements and exterior walls.

If your building has a plumbing problem, call Fullerton at (518) 776-7838. We answer 24/7 from our Albany base and serve apartment and multifamily properties across all of New York State. We will dispatch the nearest available technician, find the shared cause, give you an upfront quote and work with your tenants, then clean up before we leave.

Pricing

What Affects the Cost of Apartment and Multifamily Plumbing

Multifamily plumbing cost depends on how many units are affected, where the problem is in the building and how the lines can be reached. Clearing a stack from a roof vent or top floor cleanout is different from opening a building main in a finished basement. Larger pipe diameters, longer runs and heavy grease or scale take more time and equipment. Coordinating access across occupied units, after hours work and water heater banks with several tanks all factor in. A recurring maintenance schedule often lowers total spending. We give you an upfront quote before work starts.

I had an issue with my plumbing today and was pleasantly surprised by the exceptional service I just received. The team was very fast, helpful, and knowledgeable, completely in contrast to my usual experience trying to get a hold of a plumber. Darnel (sp) was awesome! We are definitely saving this number for any future needs. Highly recommend to anyone looking for help.

Apartment and Multifamily Plumbing Questions, Answered

Because the units above and below share the same vertical drain. When a kitchen or bathroom stack clogs, water from upper floors has nowhere to go and comes up in the lowest fixture on that line, usually the ground floor or basement unit. We clear the stack from the top or from a cleanout, then camera it to see what caused the blockage.

Yes. We repair and replace individual unit water heaters and the larger banks of tanks that supply a whole building. We check sizing against how many units and fixtures they serve, look for failing tanks before they leak, and schedule replacements so tenants lose hot water for as short a time as possible.

We give you a clear time window and a list of affected units so you can send notice. Shutoffs are limited to the smallest section of the building we can isolate. We move through units in order, protect floors and clean up in each one. Emergencies are handled right away, any hour.

Yes. We work with HOA boards, condo associations and their managers on shared lines, building mains and common area plumbing. We explain which part of the system a problem is in, give an upfront quote the board can review, and provide a written summary of the work for your records.

It depends on the building. Older buildings with cast iron stacks and heavy kitchen use often need jetting once or twice a year, while newer buildings may go much longer. We camera the lines first and base the schedule on the buildup we actually see, so you are not paying for work the building does not need.

Yes. We start in the unit above and check supply lines, drains, toilet seals, tub and shower connections and the stack itself. Water can travel along joists before it shows up, so the stain is not always directly under the source. Once we find it, we repair the leak and explain what each unit owner or tenant should know.
