Common questions
Can you replace my hot water system today?
In most cases, yes. Same-day replacement is available for most systems. Call early and tell us what you have, and we’ll confirm.
How fast can you get to me?
Same-day service is available. Tell us your suburb when you call and we’ll give you an honest arrival time. If your system is leaking badly or has burst, call us any time, 24/7.
How much will it cost?
We quote upfront before any work starts, so you know the price before we begin. No hidden costs. If it turns out to be a bigger job, we explain why and give you the options first.
Should I repair or replace?
We’ll check the system and tell you honestly. If a repair will get you good years out of it, we’ll fix it. If replacement makes more sense, we’ll put a plan together with you before doing anything.
Which systems do you work on?
Gas and electric storage, continuous flow, heat pump and solar. Hayden is a licensed gasfitter, so gas systems are covered.
