Boiler Repair in Staten Island, NY
One-pipe steam is a craft most HVAC companies quietly gave up a generation ago. On Staten Island's North Shore, we never stopped — because St. George, Stapleton, and Port Richmond never stopped running on it.
No heat or no cooling? Those calls jump the queue during open hours.

We repair steam and hot-water boilers across the borough's pre-war housing — the Victorians of St. George, the rowhomes of Stapleton, the foursquares of Port Richmond. Here's the key fact: banging pipes, spitting vents, and radiators cold at the far end are almost never boiler problems. They're venting, pitch, and piping problems wearing a boiler costume. Fixing the real cause costs a fraction of the replacement someone else might have quoted you.
Our trucks stock what this housing consumes: main vents, radiator vents, low-water cutoffs, thermocouples, circulators. We carry Weil-McLain and Utica parts too, because those are the boilers we install when replacement is the honest answer. That answer comes with evidence: photos of the failed section, and the repair price next to the replacement price.
Safety is baked into every visit. Every boiler call includes a combustion check, CO reading, and draft check. Old oil-to-gas conversions venting into original chimneys are exactly where flue problems hide — and this borough has thousands of them.
Boiler symptoms we fix at the cause
- Radiators banging at 3 AM (pitch or venting — not doom)
- Radiators hot near the boiler, cold at the ends of the run (main venting)
- Boiler losing pressure weekly or its sight glass flooding
- Constant hissing from radiator vents, or vents spitting water
- Boiler short-cycling on its low-water cutoff
- Water on the basement floor — call before it becomes the ceiling below
North Shore steam knowledge, borough-wide coverage
Steam work rewards pattern recognition, and the North Shore has given us decades of patterns. Wet returns rotted at the floor line in Stapleton basements. Mains thrown off pitch by settling foundations in St. George. Conversion burners short-cycling oversized sections everywhere. We skim boilers after piping work — the step whoever came before us usually skipped. The result is a quiet system, which is the only measure steam owners care about at night.
Hot-water systems get the same fluency: circulators, zone valves, expansion tanks, and the settings that cut fuel bills on bigger pre-wars. When replacement wins the math, the radiators you love stay right where they are.
Boiler Repair in Staten Island: quick answers
My radiators bang all night. Do I need a new boiler?
Almost certainly not. Banging in one-pipe steam is water trapped where steam wants to travel — pipe pitch or venting in the vast majority of homes. Repairs run hundreds, not thousands, and we diagnose the cause before quoting anything.
What does boiler repair cost on Staten Island?
Common repairs — vents, low-water cutoffs, thermocouples, circulators — run $250–$900 flat-rate quoted before work starts. Piping corrections and section repairs are quoted after diagnosis, with photos of exactly what we found.
Half my radiators stay cold. Can that be fixed without replacing anything big?
Usually yes — cold radiators at the end of the run mean air can't get out of the mains fast enough for steam to arrive. Proper main venting fixes it, and it's cheap relative to what it solves.
How do I know if my boiler actually needs replacing?
Cracked or leaking sections, a waterline rotted past safe repair, or repair costs crossing a third of replacement on a 30+ year unit. We show you the evidence — photos, readings, both prices — and count your radiators for honest sizing.
Do you service boilers outside the North Shore?
Borough-wide — pre-war pockets exist everywhere from Tottenville's old village blocks to Westerleigh. If it's steam or hot water on Staten Island, it's on our route, and no-heat calls jump the queue in heat season.
