Emergency Boiler Repairs:

If and when your boiler starts to malfunction it can be stressful and really frustrating. But don’t worry… Our team are on hand 24/7 to help. We can handle nearly any repair and aim to be with you as soon as possible.

We can often suggest a quick fix that will offer a temporary solution until our engineer arrives. Once we get to your property we always aim to complete the work in the shortest time possible so you can go back to enjoying a warm, safe home as soon as possible.

We take great pride in the fact that we can often respond to an emergency call within 1 hour. And we always keep our vans kitted with any tools required to respond to any plumbing emergency.

We can fix a wide range of boiler problems including: 

  • Heating system malfunctions
  • No hot water coming from your taps
  • Strange noises from the boiler or radiators 
  • Boiler or radiator leaks
  • Toilet repairs
  • Bath and Sink repair

While boilers can, and do, develop problems in summer they are far more vulnerable in the winter. This can leave you without heat and water when you need it most. In addition to repairing boilers, we can also provide an annual service that will help you avoid bigger problems down the road.

At NJ Harkus Plumbing and Heating, we have a fantastic reputation. We have quickly become the go-to plumbers for boiler repairs in Cardiff. However, we also cover multiple areas in South Wales and we won’t turn down any jobs unlike many other plumbers in the area.
