Matt came to our home was a delight to work with. Excellent workmanship and very courteous. Went above and beyond to assist. He provided us with quotes for various plumbing items, he quickly provided a detailed quote, explained options. He was excellent at commencing work in one area, and double checked water pressure in our area, hot water system and the plumbing items I had purchased. A great tradesman. Thoroughly recommend. Thankyou Matt.

Hot Water Systems in Coomera
5.0 from 200+ Google reviewsMost hot water systems in Coomera are only a handful of years old, so the calls we get here look different to an older suburb. It's less "the tank has finally rusted through" and more a builder-grade unit reaching the end of its cheapest components, a warranty question after a move-in inspection, or a system that was never quite sized right for the household using it.

Why this happens in Coomera
Coomera's housing stock is overwhelmingly new - most of it built in the last five to fifteen years as the suburb grew into one of the busiest corridors on the northern Gold Coast around the train station and business precinct. New-build hot water systems are usually the standard spec the builder included, sized to a minimum rather than to how the household actually uses hot water. That's fine for the first year or two, but it's often the reason we get called when a family has grown into the house and the system hasn't kept up.
The other pattern is warranty timing. A lot of these systems are still inside, or only just outside, their manufacturer's warranty window, and getting a straight answer on what's covered and what isn't can be harder than the repair itself. We'll tell you plainly whether something's worth claiming under warranty, worth a straightforward repair, or worth replacing properly - rather than just replacing on the first callout.
It's also worth saying plainly: a new system isn't a guarantee against early failure. A manufacturing defect or a bad original install can take down a two or three-year-old tank just as easily as a ten-year-old one, so even in a suburb this new, it's worth having a system checked properly rather than assuming age alone rules a fault out. Standard electric storage tanks generally run somewhere around 8 to 12 years in normal conditions - most Coomera systems are nowhere near that yet, which is exactly why an early fault here usually points to something specific rather than simple wear.

What we fix in Coomera
What actually happens on the job
Diagnose first
We check the tank, thermostat, elements and relief valve to find out exactly what's failed and why - not just what's dripping.
Honest advice
If it's a component fault on a system with plenty of life left, we'll repair it. If the tank itself is compromised or the unit's genuinely undersized, we'll say so.
Same-day where possible
Most replacements can be sorted same-day, so a young family isn't stuck without hot water any longer than necessary.
Correct sizing
If we're replacing, we size the new system to how the household actually uses hot water - not just to match what was there.
What it costs
Pricing for a hot water repair or replacement depends on the system type, its size, how it's accessed, and whether it's a straightforward like-for-like swap or a resizing job. We agree the price with you before any work starts, so there's no surprise once the job's done, and there's no call-out fee for us to come and take a look. A new system install also comes with $250 cash back on eligible replacements, paid once the job's finished.
Questions we get asked
How much does a hot water system cost to replace?
It depends on the type and size of system, where it's installed, and whether it's a direct swap or needs upsizing for the household. We give you an exact price on site before any work begins, based on what your home actually needs.
Is my hot water system still under warranty?
It depends on the manufacturer, the install date and what's failed. If your system was fitted during the original build, we can check the warranty status and let you know honestly whether the fault is a warranty claim or a straightforward repair.
My hot water runs out fast - is that a fault or is the system just too small?
Often it's sizing, not a fault. Builder-installed systems are commonly sized to a minimum, and a household that's grown since move-in can outpace a unit that was working fine a couple of years ago. We can tell you which it is and what a properly sized replacement looks like.
Do you work on continuous flow systems as well as storage tanks?
Yes, we handle both electric storage tanks and continuous flow units, which is what most Coomera builds have installed.

Had an issue with our 16 year old toilet leaking from underneath the pan somewhere. Called Blake & he sent Lachlan out the following morning to diagnose & quote. Lachlan gave us 3 options, which was great. We chose the middle one, which included replacing all the internals, so hopefully we should be OK for another 16 years! Both Blake & Lachlan were great to deal with & Lachlan did a great job - definitely better than the original installation, which looked a bit dodgy! Happy to recommend.
fantastic plumbing experience GENIES Plumbing installed a new shower for me. Sensational job done. THEY WERE FRIENDLY, DILIGENT, answered all questions, cleaned up, Very happy with the finished product. Thank you GENIES plumbing!
This is the type of plumbing service that everybody wants. They quote before they do the job. They turn up when they say they will. And they're very good at what they do. Good Service - Fair Price - not something you normally say about Plumbers these days. Keep up the great work Blake, Lachie and Raif.
Amazing service. Highly recommend Lachlan and Genies Plumbing. Thank you for taking time out of your Saturday to put in my new hot water system. Truly a work of art!
Absolutely amazing service from the moment I got in touch with them, and in particular Blake. I explained to him my issue and he took the time and effort (completely unprompted) in providing steps of how he would tackle the problem. When it came time to actually have the issue physically looked at, Lachie gave me a call and let me know how far away he was; he arrived promptly and on-time, and was able to very quickly diagnose and provide a solution. I was quoted on the spot and not pressured whatsoever to have more things looked at than I needed to, which I very much appreciated. While I've got my fingers crossed to not have any further short-term issues with my property's plumbing, I'd wholeheartedly recommend these guys and gals to anyone willing to listen. I'm sure there are many other great plumbing businesses around the Gold Coast, but for my money I'd much rather support a local family-owned business providing a very honest and transparent service, who also aren't looking to bleed your wallet dry.
Very happy with the service from Genies Plumbing. We had a leaking kitchen tap and Blake was out in a couple of hours. He sourced a new one, came back later in the day and fitted it. He advised his arrival times very efficiently and was friendly and polite. Would certainly recommend him and call on him again when necessary.
Matty was honest, genuine, and professional from start to finish. It’s not always easy to find a plumber you can trust, but Matty was upfront, reliable, and took the time to explain everything clearly. A great company with fantastic service. I highly recommend to anyone looking for a trustworthy plumber. I wish them every bit of success in the future - they truly deserve it!
Genie plumbing was magic !! Locky was here on time and knew his trade !! We are doing a renovation in the bathroom and he was great! He is coming back today to install the hot n cold pipes, then the fit out next. The drainage was installed first trip. Nothing was a problem for Lochy ! Good pricing and would definitely recommend Genie Plumbing ✓ Worth 6 stars ★★★★★★ Geoff Tamplin
I live in a unit complex and had to get my hot water system replaced as it was old and also to meet the current standards and regulations. I contacted the boys at Genies Plumbing. To say I was happy with their service is an understatement. I would not hesitate to recommend them to anyone. They were prompt professional and very neat and tidy and took the time to show me how everything worked and answer all my questions. Thanks Blake and Lachlan for a great job.
Really Impressed !!! Blake and Genies Plumbing did an amazing job and a great price. They listened to what I needed and made it work. They were available really quickly to do the job and I’m really happy with the result.... Already got a couple more jobs for them to do...Well Done Genies Plumbing
Lachlan from Genies Plumbing arrived on time and thoroughly looked over the job before providing us with a quote which he fully explained. He then cracked on with the work and did an amazing job! He was super easy to deal with and had our bathroom fitted off and functioning within a couple of hours. Very pleased we used Genies Plumbing and would recommend them.
Genies Plumbing team was very friendly and explained the different options we could choose from. They were able to do the job the next day! Would recommend and will be having them again for any plumbing needs.
I had a blocked kitchen sink and was quite concerned about the potential for damage and inconvenience. I called Genies Plumbing and once again received outstanding service from Blake. He was prompt, professional, and explained everything clearly. This isn’t the first time I’ve called on Blake, and every time he delivers reliable, high-quality work with genuine care. I really appreciate his consistency, attention to detail, and friendly approach. Highly recommend Genies Plumbing — especially Blake — for exceptional service you can trust!
Blake and Lachlan assisted us with a very complex realignment. They were brilliant. They took the time to explain everything, kept me updated with any issues that arose, kept on time and impressively on budget. They could not have worked harder to resolve our issues. I was so worried that we would need to crack our slab and have to retile the majority of our house. These boys made a plan and stuck to it. Fabulous outcome!!
Great service, friendly, reliable and professional. Thanks to Blake and Lachy, we had a water main leak detected and repaired in no time. They went above and beyond to make sure we had rectified the issue quickly. Highly recommended and will be using Genies for all of our plumbing needs in the future
Blake and Lachlan from Genies Plumbing were really helpful when installing a new hot water heater in my home. It was a quick process with excellent workmanship and very reasonable cost. They were both lovely to deal with and communicated with me at all times. I am so glad Genies Plumbing was recommended to me by my electrician. Will definitely call on them again. Trish
From the moment we made the call with our list of to do's - to the moment the boys came and left after the job completion- the entire help was incredible, and the workmanship was thorough and detailed and reasonable". This workmanship advise is Beyond MOST service and help we have experienced over the last few years. Thank you boys! This type of experience is often not the most favourite one for many people, but in this case, what a great time to get everything sorted with an ease of mind and honesty personified. 2 showers 1 bath 1 laundry 1 bathroom sink Thanks again team - we'll see you again. You'll be our first point of call . A++++
I called Blake to help locate a tricky water leak on our acreage property, he quickly identified multiple leaks on both the council and our side of the line and got them all fixed. He kept us informed every step of the way, and was incredibly responsive and professional, and a genuinely nice person. He's also helping put together a storm water system to help manage the water drainage away from the house during storms. I wouldn’t hesitate recommending Blake for any plumbing job, big or small.
Had some plumbing work done by Blake from Genies Plumbing — removal of an old water meter and repair/replacement of some leaking pipework. Communication was great from start to finish, he was prompt, friendly, well priced, and made sure everything was cleaned up afterwards. Really happy with the work. Would definitely recommend and use again.
