Manhattan's housing stock is predominantly pre-war — roughly 68 percent of units were built before 1940, concentrated in the tenement blocks of lower Manhattan and the mid- and high-rise apartment buildings erected along the major avenues between 1900 and 1939. The dominant heating system across that stock is one-pipe steam: a basement boiler, galvanized or black-iron steam mains, and cast-iron radiators that have been running for 80 to 100 years. Supply plumbing in unrenovated units typically means corroded galvanized branch lines hidden behind original tile, and many buildings carry original cast-iron waste stacks sized to a population density that predates modern fixtures. We work Manhattan for building-wide boiler replacements, steam system rebalancing, supply line re-pipes, and the HVAC mechanical rough-ins that co-op and condo renovation projects increasingly require.

Our Manhattan building's one-pipe steam system runs too hot — the whole building is overheating. Can that be fixed without replacing the system?

Yes. Overheating in a one-pipe steam building is almost always a control problem, not a system problem. The most common cause is a thermostat located in a cold spot (a lobby or north-facing room) that keeps calling for heat after the rest of the building is warm. Adding thermostatic radiator valves (TRVs) to individual radiators allows each room to limit heat without shutting down the whole system. Recalibrating the aquastat and pressure settings also helps. These are targeted modifications to the existing system, not a replacement.

We're doing a renovation in our Manhattan co-op — how does plumbing work get handled in a co-op building?

Co-op renovations in Manhattan require board approval and usually a licensed plumber with insurance documentation on file with the building. The shareholder is responsible for work within the unit; the building owns the risers and stacks in the walls. Most co-op alteration agreements require work permits from the DOB for anything beyond simple fixture replacement. We work in Manhattan co-op buildings regularly and handle the permit filing, insurance documentation, and coordination with building management as part of the job.
