Greenwood Heights sits on the high ground next to Green-Wood Cemetery, between South Slope and Sunset Park. Its side streets between Fourth and Fifth Avenues are lined with brick and frame row houses and small walk-ups from the late 1800s and early 1900s. Fourth Avenue now has many newer apartment buildings, and the R train stops at Prospect Avenue and 25th Street. Battle Hill, inside the cemetery, is the highest point in Brooklyn.

The neighborhood slopes down toward the harbor, so sewer lines here generally have good fall, but the older ones are clay and cast iron that have been in the ground a long time. Many houses were divided into rentals, which puts more fixtures on original pipes. The newer Fourth Avenue buildings bring different needs: backflow preventers, commercial water heaters and the gas piping inspections required for multifamily buildings.

Common plumbing issues in Greenwood Heights
Clay sewers under old row houses
Row houses from around 1900 typically have clay house sewers running under the front yard and sidewalk. Even with good slope, joints shift over a century and roots find their way in. Slow basement drains and gurgling toilets are the early signs. Jetting clears roots and buildup, and a camera inspection shows whether the pipe needs repair.
Rentals on original piping
Many houses here have two or three apartments sharing one water service, one sewer and one water heater or boiler. Hot water runs short, top floor pressure drops when other units use water, and a single clog affects everyone. We look at the whole house system and recommend the fix that solves the actual bottleneck.
New buildings, new requirements
The apartment buildings along Fourth Avenue have backflow preventers that need annual tests, gas piping on the Local Law 152 cycle, and commercial-grade water heaters. We handle the testing, inspections and repairs for owners and managers, trace leaks between units, and provide certificates of insurance to boards and managing agents.
Gas piping in divided houses
When a row house is split into three or more apartments, it becomes subject to Local Law 152 gas piping inspections, and each added range or dryer is another branch on old gas pipe. Leaks at old fittings are a common finding. We perform the inspection, make repairs, and file the GPS2 certification with the Department of Buildings.

Plumbing in Greenwood Heights: FAQ
Is Greenwood Heights the same as South Slope?
They border each other, and people draw the line between them in different places. Either way, both are within our NYC service area, and we dispatch 24/7 for leaks, backups and no-heat calls across this part of Brooklyn.
Our house has three apartments and not enough hot water. What are the options?
A larger tank, separate heaters for each unit, or a high-output tankless system can all work. The right choice depends on your gas service, venting and space. We check those and give a free written estimate. Financing is available through Wisetack.
How do I know if my sewer line has roots?
Slow drains in the basement, gurgling toilets and backups after heavy use are common signs. The only way to know for sure is a camera inspection. If roots are there, jetting clears them, and the camera shows whether the pipe is cracked or still sound.
