High-pressure flush clears sludge and rust, restoring flow so the whole system runs hotter and cleaner.
Leaks around valves, joints and heating pipework traced and repaired before they cause damage.
Sizing, sourcing and fitting new radiators — including draining, refilling and balancing the system.
Full system checks and servicing to keep everything running efficiently before the winter sets in.
Heating failed or a leak on the system? Call and we'll get to you as quickly as possible.
Cold spots at the bottom of a radiator are almost always a build-up of sludge and rust inside the system. Over time it settles at the lowest point and restricts the flow of hot water through the radiator — one of the most common heating problems we see in Cork homes.
The fix is a power flush: a high-pressure flow of water and cleaning solution pushed through the whole system to clear the build-up.
If a radiator is beyond repair, corroded, or simply not big enough for the room, we’ll replace it. Colin advises on the right size and output for the space, sources the radiator, and carries out the full installation.
That means draining the system, fitting the new unit, then refilling and balancing the heating — so the new radiator performs from day one.

Cold spots at the bottom of a radiator are usually caused by a build-up of sludge and rust inside the system. Over time this settles at the lowest point and restricts the flow of hot water through the radiator. It’s one of the most common heating problems we deal with in Cork homes.
The fix is a power flush. This pushes a high-pressure flow of water and cleaning solution through the entire system to clear out the build-up. After a power flush your radiators heat up faster, your boiler runs more efficiently, and the system lasts longer. It’s worth doing every 5 to 7 years, particularly in older Cork properties that haven’t had any heating maintenance carried out in some time.

How do I know if my radiators need power flushing? The most common signs are cold spots at the bottom of radiators, the system taking a long time to heat up, some radiators heating unevenly, and your boiler working harder than usual. If your heating system hasn’t been flushed in several years it’s worth getting it checked, particularly before the winter months.
How much does it cost to replace a radiator in Cork? The cost depends on the size of the radiator and the amount of pipework involved. Straightforward like-for-like replacements are generally more affordable than jobs requiring pipe adjustments or moving the radiator to a new position. Call us for a quote specific to your situation.
How long do central heating radiators last? Most radiators last between 15 and 20 years with regular maintenance. Poor water quality and sludge build-up are the main causes of early deterioration. A power flush and inhibitor top-up every few years can significantly extend the life of your system.
Is it worth replacing old radiators? In most cases yes. Radiators that are 20 years or older are often less efficient, more prone to leaking, and harder to balance correctly. Replacing them improves heat output, puts less strain on the boiler, and can reduce your heating bills over time.
What are the signs a radiator valve needs replacing? Common signs include a radiator that won’t heat up even after bleeding, a valve that’s stuck open or closed, or visible dripping or corrosion around the valve body. Thermostatic valves can also fail electronically and stop responding to temperature changes.
