What's your boiler problem?
Let us know what's happening and we will guide you through the next step.
You don't need to face it alone
Whatever has happened with your boiler, there is a clear next step. Here is what to do if you are dealing with any of the following.
Loss of Heating
If your radiators have gone cold, check your thermostat and timer first. If the boiler still won't heat, get in touch and we will talk you through it.
No Hot Water
No hot water can point to a few different causes. Our team can talk through what you are experiencing and arrange a visit to diagnose it properly.
Boiler Shutdowns
A boiler that keeps shutting off is often protecting itself from a fault. Do not keep resetting it repeatedly, contact us and we will investigate the cause.
Fault Codes
An error code on your display is useful information for our engineers. Have the code ready when you contact us so we can advise on next steps.
Boiler faults we diagnose and repair across Dublin
From minor faults to more involved repairs, our engineers work through the full range of gas boiler problems homeowners, landlords and businesses experience.
No Heating

Request a Commercial Boiler RepairUnderstanding the causes behind common faults
Boiler breakdowns rarely happen for just one reason. Understanding the general causes can help you make sense of what your boiler is going through, without needing to become an expert yourself.
Wear and tear
Like any mechanical system, boilers experience gradual wear on moving parts and seals over years of use.
Component failures
Individual parts such as valves, sensors or circuit boards can fail independently of the boiler's overall condition.
Lack of maintenance
Boilers that go long periods without any attention can develop issues that build up gradually.
Pressure issues
Incorrect pressure levels place strain on the system and can be a symptom of an underlying fault.
Ageing systems
Older boilers naturally become more prone to faults as components reach the end of their working life.
The value of getting it diagnosed properly
Accurate Diagnosis
Correctly identifying the fault avoids unnecessary work and gets to the real cause.
Safety Considerations
Gas boilers require careful, competent handling for the safety of your household or premises.
Long Term Reliability
A proper repair addresses the underlying issue rather than just the symptoms.

Careful, considered repairs carried out to a high standard every time.
