How we can help

No hot water is one of the most disruptive problems a household can have. We diagnose the fault first and tell you honestly whether a repair makes sense or if replacement is the better value.

If you do need a new system, we'll explain the options — continuous flow, storage, heat pump or solar — and what each will cost to run, then install it neatly and to code.

Common problems we solve

  • No hot water or lukewarm water
  • Pilot light that won’t stay lit
  • Leaking hot water tank or relief valve
  • Water that runs hot then cold
  • Rusty or discoloured hot water
  • Noisy or rumbling systems
  • Old systems near the end of their life

What to expect

  1. 1

    Diagnose

    We test the system and find the actual fault — thermostat, element, thermocouple, valve or tank.

  2. 2

    Repair or replace advice

    We tell you straight whether repairing it is worth the money, based on the age and condition of the unit.

  3. 3

    Clear quote

    Written price for the repair or for the supply and installation of the new system, including removal of the old one.

  4. 4

    Install and test

    Installed to Victorian standards with the correct valves, tested, and the area left clean.

Pricing & quotes

Repairs are quoted after diagnosis. Replacements are quoted as a fixed price for supply, installation and removal of the old unit, so you can compare options side by side.

* The $0 call-out fee applies when you go ahead with the quoted work. If you decide not to proceed after we have attended and quoted, a $49 dispatch fee applies. See all offers & our guarantee.

Frequently asked questions

Should I repair or replace my hot water system?

If the tank itself is leaking, replacement is usually the only fix. For other faults on a system that's otherwise in good shape, a repair is often the better value. We'll give you an honest recommendation.

Can you replace my system on the same day?

Often, yes — depending on the system you choose and what our suppliers have in stock. We'll confirm before booking.

Which type of system is cheapest to run?

It depends on your household size, available energy sources and space. Heat pumps and continuous-flow gas systems are popular options; we can talk you through the trade-offs.
