Staten Island homes often have a boiler serving radiators or baseboard heat, and a radiator that will not heat can leave part of the house cold. The cause is usually a valve, a vent, trapped air or a balance issue, and we can usually tell you quickly which. We repair radiators across Staten Island and let you know when the boiler is the real problem.

When the whole system is yours, a radiator problem is easy to isolate: one cold radiator is local, several cold radiators suggest the boiler or circulator.
Heat may reach lower levels more easily than upper ones. Air in the system and unbalanced zones are common causes.
Original radiators and piping may need new valves or vents even when the radiators themselves are sound.
A radiator that heats well in the morning and poorly in the evening, or one that gets hot only at the bottom, points to specific causes. We ask what you see and narrow it down before we arrive.
Before heating season, bleed hot-water radiators if you know how, and call us if a radiator leaks, spits water or never warms up. Early repairs are cheaper than a winter emergency.
In a New Dorp split-level, the upstairs radiators are cold while the first floor is warm. In a St. George rowhouse, an old radiator valve has started to weep. In a Tottenville home, a radiator is hot at the bottom and cold at the top. Each has a straightforward explanation: air, a failing valve or a balance issue.
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 Staten Island.
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 Staten Island, see emergency plumbing in Staten Island.
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.
