In the Bronx, radiators heat everything from pre-war apartments to large co-op towers and private homes. When a radiator is cold, leaking or banging, the cause is usually at the valve or vent, but in an apartment building it can also be a building-level problem. We repair radiator valves, vents and leaks across the Bronx and say clearly when the cause is upstream.

Steam radiators are common in older buildings. A failed vent or stuck valve leaves one radiator cold while the others work.
If many apartments are cold, the boiler or distribution system is the likelier cause, not the individual radiators.
Private homes may have hot-water radiators or baseboards. Air and valve problems are common.
The most useful thing to know before we arrive is whether the problem is just your radiator or your whole floor or building. A single cold radiator is a radiator repair. A cold building is a boiler matter, and the radiators cannot fix it.
If your building has no heat, report it to your landlord or building management. If you are responsible for the building, call us and tell us how many apartments are affected.
In a Fordham pre-war building, a radiator bangs when the heat comes on. In a Riverdale house, a radiator drips from the valve. In a large co-op tower, several apartments on one line have no heat and the problem is upstream. Knowing which of those you have saves time, so we ask first and diagnose accordingly.
These are illustrations of the kinds of problems we are asked about, not case studies.
On a steam system, a radiator needs its air vent to release air so steam can fill it. A clogged or failed vent leaves it cold. A radiator that is not pitched back toward its supply valve can collect water and bang. On a hot-water system, trapped air collects at the top and leaves the radiator cold there until it is bled. A valve that is stuck or closed stops flow on either system, and a leak at the valve packing or union usually means a worn part.
If many radiators or the whole building are cold, the cause may be the boiler. See boiler repair in The Bronx.
Place a pan and towel under the leak, and if you can safely turn the radiator valve off, do. On a steam radiator, do not open vents or unions, because the unit can be hot and under pressure. A persistent drip can damage floors and the unit below, so call promptly. For urgent water problems in the Bronx, see emergency plumbing in The Bronx.
Steam radiators usually have a single supply valve and an air vent, and depend on the vent letting air out so steam can fill the unit. Hot-water radiators are fed by a pump, often have a bleeder valve at the top, and depend on air being removed from the system. Identifying which you have is the first step of any repair.
Cast-iron radiators can last a very long time, but their valves, vents and connections are wear items. Most radiator problems are fixed at those parts and not by replacing the radiator.
Confirm that the radiator valve is fully open and that other radiators in the home are heating. On a hot-water radiator that is hot at the bottom and cold at the top, air may need to be bled from the bleeder valve. Do not try to open or force a steam vent or union, because they can be hot and under pressure. If the radiator still does not heat, call us and describe what you see.
A single vent or valve replacement is usually the simplest repair. Scope grows when the system must be drained, when valves are seized, when pipes have sagged or when the cause is upstream. We explain what we find as we find it, and say so when the boiler is the real problem.
