Brisbane’s Reliable Hot Water Repairs

Does your hot water system need repair or replacement?

If your hot water has suddenly gone cold, your hot water system is leaking or something else isn’t quite right we can fix it fast.

We repair, service and replace all brands and types of hot water systems, including:

  • Electric
  • Solar
  • Gas and Gas-instantaneous
  • Heat-pump

It’s often more cost effective to repair a hot water system than to replace it – however depending on the type of system you have and how old it is – replacement can also be very cost effective.

Some situations are clear-cut and either repair or replacement is the obvious solution – but sometimes an inspection and discussion of the options, costs and implications of each is the best way to proceed. 

Our Hot Water Services include

  • Install new hot water system
  • Fix leaking hot water system
  • Fix water pressure and flow problems
  • Fix temperature of water (if it is too hot or too cold)
  • Restore clear hot water where water has discoloured
  • Replace parts for hot water system
  • Remove old hot water system
