Boiler Repair · Steam & Hot-Water Systems
Boiler Repair in Brooklyn — Steam & Hot-Water Systems
No heat is the call we answer fastest. We repair both kinds of NYC boiler — hot-water systems and steam — around the clock for genuine emergencies.
We diagnose before we quote, quote before we work, and fix causes instead of symptoms.
The Symptoms We're Called For
No heat at all.
Thermostat calling, boiler silent — power, ignition, gas supply, safeties, or controls. This is the classic emergency call, and diagnosis usually goes fast for someone who does it daily.
Leaking or dripping.
From a relief valve, a fitting, or the boiler itself. Relief valves and fittings are repairs; water from the boiler block is a bigger conversation — we tell you which, straight, before anything is sold.
Banging, kettling, and strange noises.
In steam systems, banging is water hammer with findable causes. In hot-water boilers, kettling usually means scale on the heat exchanger. Either way, the noise has a cause worth finding. Steam noises, explained →
Pilot and ignition failures.
Thermocouples, igniters, flame sensors, and gas valves — the highest-frequency boiler repairs there are. Recurring ignition failure has an underlying cause; replacing the same part every October is not a maintenance plan.
Short-cycling.
Fires, shuts off, fires again minutes later. Causes range from oversizing to control settings to (in steam) pressure set far too high. Wastes fuel, eats components, and is very fixable.
Pressure problems.
Hot-water systems losing pressure point at leaks or expansion-tank failure; steam systems running high pressure point at controls and venting. Both show up on gauges before they show up as failures.
No Heat in a Tenant Building: The Legal Clock
For landlords, a dead boiler starts two clocks. The comfort clock — tenants are cold now — and the legal one: NYC requires owners to provide heat during heat season and hot water year-round, and HPD complaints turn quickly into inspections and violations. Document when the failure started, tell us the building is occupied, and we prioritize accordingly. The owner's guide to HPD heat & hot-water rules →
For true middle-of-the-night failures, our 24/7 emergency line → is the front door.
Repair vs. Replace, Called Straight
Every repair visit ends with one of three verdicts, in writing: fixed and healthy (most calls), fixed but watch it, or this money belongs in a replacement. That last one comes with numbers for both paths.
The best repair, of course, is the one that happens in September instead of January — that's what The Boiler Physical is for →
Gas-Fired Means Licensed
Most boiler repairs touch the gas train eventually — valves, pilots, regulators, the piping that feeds them. In NYC that's Licensed Master Plumber work, so a repair from this shop never ends with a referral to go find one. The gas license behind every repair →
FAQ
Frequently Asked Questions
What should I expect an emergency boiler repair to cost?
A diagnosis first, then a written price before any repair begins, even on emergency calls. After-hours response carries emergency rates, which we tell you on the phone. The price drivers are the failed component, access, and whether the fix is at the boiler or in the distribution system.
Can you come today?
For no-heat calls in occupied buildings during heat season, that’s the goal, and usually the reality in Brooklyn and Queens. Severity orders the queue: no heat with tenants beats a noisy radiator, and everyone gets a real ETA.
Do you repair steam boilers too?
Yes — steam is a specialty, not an exception. Low-water cutoffs, feeders, pressure controls, near-boiler piping, flooding and surging: we repair the steam-specific failures that leave other contractors guessing.
My boiler was red-tagged — what happens now?
A red tag means the utility found an unsafe condition and suspended gas to the equipment — no heat or hot water from it until the condition is corrected and re-inspected. The path back is licensed work: corrective repair (often with a DOB permit), pressure testing where required, and utility coordination for re-inspection and restoration. We handle red tags end to end, including the paperwork trail; if the tag has already produced a DOB or HPD violation, we clear that too.
How long should a repair keep my boiler going?
Depends what failed and how old the boiler is. A new ignition module on a mid-life boiler is a real fix with years in it. A circulator on a 25-year-old plant is a fair repair — but we’ll tell you it’s the beginning of a pattern, not the end of one. When repair money would be better spent on replacement, we say so with numbers, and the decision stays yours.
