Boiler work is plumbing work. Water, pressure, pitch, venting and piping decide whether a boiler heats quietly or hammers and leaks. Our technicians are licensed plumbers, which is why boilers are something we do well rather than something we tolerate.
Signs your boiler needs repair
- No heat, or the boiler fires but radiators and baseboard stay cold
- Water on the floor around the boiler, or dripping from the relief valve pipe
- Loud banging in the pipes or radiators when the heat comes on
- A hot-water system that needs the pressure topped up again and again
- A steam boiler that needs water added every few days, or floods the sight glass
- Radiators that heat on one floor but not another, or only at the near end of a loop
- Rust water or debris in the sight glass, or spitting steam vents
- The boiler short cycles, or the pressure gauge climbs toward the relief setting
Boiler services we provide
Hot-water boiler repairs
Circulator pumps, zone valves and zone relays, expansion tanks, pressure-reducing fill valves, relief valves, aquastats, air eliminators, and bleeding air out of loops that have gone quiet.
Steam boiler repairs
Low-water cutoffs, pressuretrols and vaporstats, pigtails that clog with sludge, sight glasses, auto feeders, main vents and radiator vents, steam traps on two-pipe systems, and the near-boiler piping that controls how dry the steam is.
Leaking boiler sections and piping
A leak between the sections of a cast iron boiler usually means the boiler is at the end of its life, and we say so. Leaks at the piping, valves, pump flanges and radiators are repairable and we fix them.
Annual boiler service
Cleaning the burners and flue passages, testing every safety control, flushing the low-water cutoff on steam, checking the expansion tank on hot water, and a combustion test before the season starts.
High-efficiency condensing boiler replacement
Modern condensing boilers extract far more heat from the same gas, vent through PVC, and modulate to match the load. They are a strong fit for hot-water baseboard and radiator systems, and we install them with the proper piping, controls and condensate handling.
Combi boilers
A combi boiler heats the house and supplies domestic hot water from one wall-hung unit, freeing up the space a tank water heater took. Right for many smaller homes and condos; we tell you when it is not the right fit.
Steam boiler replacement
Steam boilers must be piped exactly as the manufacturer specifies or the system will bang and throw water. We size by connected radiation, not square footage, and pipe them correctly.
Radiator and baseboard work
Replacing radiator valves and vents, repairing leaking baseboard elements, adding or moving radiators, and re-pitching steam radiators that pool and knock.
How a boiler repair call works
- 1
Call and tell us what the boiler is doing
We may ask about the pressure gauge, the sight glass or whether the emergency switch got bumped, which solves more no-heat calls than you would think.
- 2
Diagnosis at the boiler
We check the controls, the water level or pressure, the pump, the venting and the flame, and trace the problem to the component that failed.
- 3
Firm price and an honest recommendation
You get a by-the-job price for the repair. If the boiler section is leaking or the unit is near the end of its life, you also get a replacement number so you can compare.
- 4
Repair, fill, bleed, test
We complete the repair, refill and purge air or set the steam water level, run a full heating cycle, and check every zone or radiator before we leave.
Steam heat in older North Jersey homes
Steam is not obsolete; it is misunderstood. A one-pipe steam system with clean main vents, properly pitched radiators, a boiler at the right water level and near-boiler piping done to the manufacturer's diagram heats evenly and quietly. Most of the noisy, uneven steam systems we see have simply been neglected or repaired by people who treat them like hot-water systems.
We service the whole system, not just the boiler: the main vents at the ends of the steam mains, the radiator vents that let air out so steam can enter, the pitch of every radiator, and the water quality in the boiler. If your steam system bangs, runs out of water, or leaves the third floor cold, there is a reason, and we can find it.
