The single most important safety device on your steam boiler — and the most common reason boilers shut down. We test, clean, and replace when needed.
Air vent stuck closed, low water level, dirty sight glass, or steam not reaching the radiator. Usually fixable without major work.
"Water hammer" — caused by condensate backing up where it shouldn't. Pitch issues, blocked main vent, or failing steam trap. Annoying but fixable.
Water surface contaminated with oil or sludge. Often means the boiler needs skimming. Affects efficiency and safety.
Boiler fires, runs briefly, shuts off. Usually pressuretrol set wrong, or pigtail (siphon) clogged. Wastes fuel.
Low water, water disappearing, or filling too much. Could be low water cutoff sensor, auto-feeder issue, or hidden leak.
Some rooms toasty, others freezing. Usually venting issues, blocked radiator valves, or main steam line problems.
Won't light, won't stay lit, weak flame, or gas valve issues. Common in older boilers with original burner assemblies.

Very common in older Union County homes. Steam heating was the standard from the 1900s through the 1950s — and most original systems are still running. We'll walk you through what you have, what's normal vs. what's a problem, and what maintenance the boiler needs. No talking down to you, no jargon.
Maybe — maybe not. Old cast-iron steam boilers are workhorses. We've seen 70- and 80-year-old units still running well with proper maintenance. We assess: pressure vessel condition, efficiency, parts availability, and your fuel costs. If repair makes sense, we repair. If replacement is genuinely the better call, we tell you straight.
No. It's a common myth that "steam pipes just bang." Banging is condensate (water) getting smashed by steam — and it's always fixable. Usually pitch, venting, or a failing steam trap. We hear it, find the cause, and fix it. Your house can be quiet.
Hear this constantly. Steam expertise has been disappearing from the trade — newer plumbers are trained on hot water and forced-air systems. We're one of the few in Union County that still services steam comprehensively. If you've been told "we don't do steam" or "you should just replace it," call us before you spend the money.

40+ years working on steam systems in Union County. Elizabeth, Hillside, Roselle, Union — we know these old homes.
Many newer plumbers don't work on steam. We do — and we know the diagnostics that take experience to learn.
Old steam boilers often have decades of life left. We don't push replacement unless it's actually time.
