Boiler Repair in Basement

Common Boiler Issues We Fix

No Heat or Hot Water: If your radiators are cold or you're not getting hot water, we'll pinpoint the issue—whether it’s a thermostat, pump, or ignition problem—and get things flowing again.
Unusual Noises: Banging, whistling, or gurgling sounds from your boiler could signal limescale buildup, trapped air, or failing components. We’ll investigate and resolve the root cause.
Leaking or Dripping: A leaking boiler is often a sign of internal failure. We’ll identify the source of the leak and make professional repairs to prevent water damage or further system breakdowns.
Low Pressure: Low boiler pressure can affect performance and efficiency. Our team will check for leaks, bleeding radiators, or faulty pressure valves to restore optimal pressure.
Faulty Thermostat: If your thermostat isn’t responding properly, your heating system won’t work efficiently. We’ll calibrate or replace it as needed for consistent temperature control.
Pilot Light Goes Out: We troubleshoot pilot light issues, whether it’s a faulty thermocouple, gas supply problem, or air in the system.
