Common Boiler Issues We Repair

We repair all types of boiler issues to keep your heating system running smoothly. Our experienced engineers quickly diagnose and fix problems, ensuring your boiler operates safely and efficiently. Here are some common faults we repair:

Broken Thermostat Repairs

A faulty thermostat can cause your boiler to heat unevenly or not work at all. Our team checks for wiring issues, sensor faults, and calibration errors. We repair or replace faulty thermostats to restore precise temperature control, improving efficiency and comfort.

Leaking Boiler Repairs

Boiler leaks happen due to worn seals, corroded pipes, or pressure problems. Ignoring them can cause serious damage. Our engineers find the leak immediately to replace faulty parts, and then they seal the system properly. We ensure your boiler is safe and leak-free.

Low Boiler Pressure Repairs

Low pressure can cause your boiler to shut down or heat water inefficiently. This issue is often due to leaks, faulty pressure relief valves, or bleeding radiators. We inspect the system, fix any leaks, and repressurize the boiler to optimal levels.

Pilot Light Issue

If your pilot light keeps going out, it could be due to a faulty thermocouple, gas supply issues, or debris buildup. Our team cleans or replaces defective parts, ensuring a steady flame and reliable boiler operation.
