Gramercy Park is built around the only private park in Manhattan, a fenced square between 20th and 21st Streets that only nearby residents hold keys to. The blocks around it are some of the best preserved in the city: 19th century townhouses, brownstones, early apartment houses and pre-war co-ops, much of it inside the Gramercy Park Historic District. Irving Place runs south from the park toward Union Square, with restaurants and cafes on its ground floors.

Buildings this old run on aging systems. Townhouses often have their own steam or hot water boiler in the cellar, with piping that has been reworked over many renovations. Co-op buildings have shared risers, strict alteration rules and boards that want insurance paperwork before a plumber steps inside. We work with owners, shareholders and managing agents, and every job starts with a written estimate so there are no surprises on the invoice.

Common plumbing issues in Gramercy Park
Townhouse boilers with a long history
A Gramercy townhouse may have gone from coal to oil to gas heat over the decades, with a newer boiler connected to near-original radiator piping. Short cycling, cold top floors and leaking radiator valves are common results. We look at the whole system, not just the burner, and tell you in writing whether a repair will hold or a replacement makes more sense.
Shared risers in pre-war co-ops
In most co-ops the supply and waste risers belong to the building, while fixtures and branch lines belong to the shareholder. When water comes through a ceiling, knowing which side the leak is on matters for who pays. We trace the leak, document where it starts, and work with the super and managing agent so the repair gets approved without delay.
Gas piping in older multifamily buildings
Buildings with gas service, other than one and two family homes, need periodic Local Law 152 inspections. In older buildings inspectors often find corroded piping, unapproved connections or missing shutoffs. We perform the LL152 inspection, file the GPS2, and complete the repairs, including gas riser replacement when the risers are past saving.

Plumbing in Gramercy Park: FAQ
Do you work on steam heat in Gramercy townhouses?
Yes. We repair and replace steam and hot water boilers, fix leaking radiator valves and vents, and correct piping problems that cause banging or uneven heat. For replacements we give a free written estimate and walk you through the options before any work starts.
Our co-op requires paperwork before plumbing work. Can you provide it?
Yes. We supply certificates of insurance naming the co-op and managing agent, a written scope of work, and our license information. That is usually what a board or managing agent needs to approve a repair or a renovation.
Who pays when the leak in my co-op comes from the riser?
That depends on your building's proprietary lease and house rules, so it is not our call. What we can do is show clearly whether the leak is in the building riser or the apartment's branch line, document it, and give the super and managing agent a written description.
