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.

Leak Detection in Mermaid Waters
5.0 from 200+ Google reviewsMermaid Waters has one of the highest concentrations of in-ground pools on the Gold Coast, and a lot of the canal-front blocks here also carry established paving, pool decking and mature gardens that make a rising water bill genuinely hard to diagnose by eye. We don't guess. We test the meter, rule out the pool and irrigation, then narrow the leak down with pressure testing and acoustic listening equipment before anyone puts a shovel or a jackhammer near your paving.

Why this happens in Mermaid Waters
Mermaid Waters was developed substantially through the 1970s to 90s as one of the original Gold Coast canal estates, and a lot of the plumbing installed then is now well past the point where quiet, slow leaks start turning up. Being this close to Lake Hugh Muntz and the surrounding canal network also means salt-laden air, which corrodes older copper fittings and joints faster than you'd see a few kilometres inland - that's a common cause of leaks that show up as damp patches or a creeping water bill with no obvious source.
Then there's the pools. With so many established in-ground pools on canal-front blocks, a leak can be sitting in the pool shell, the pool's own pipework, or the equipment pad rather than the household plumbing at all - and telling the difference matters, because you don't want to start pulling up pool coping to chase a leak that's actually in the house line, or vice versa.

What we fix in Mermaid Waters
What actually happens on the job
Meter test
We shut off every water source in the house and watch the meter. If it's still moving, there's a leak somewhere in the system.
Rule out the pool and irrigation
On a property like this, the pool and any garden irrigation are the first things we isolate and test, since they're common culprits on canal-front blocks.
Pressure test the sections
We isolate individual lines to narrow the leak down to a specific run of pipe, rather than the whole property.
Acoustic and thermal detection
Once we know roughly where the leak is, acoustic listening equipment and thermal imaging pinpoint the exact spot - through concrete, through paving, under pool decking - without digging test holes.
What it costs
Leak detection is from $299 - acoustic leak detection from $299 - with $0 call-out fee, whether that means testing an open lawn line or isolating the pool, irrigation and a driveway run as separate systems. The repair, if one's needed, gets quoted separately once we know exactly what we're dealing with.
Questions we get asked
What is the average cost of leak detection?
Leak detection is from $299, with $0 call-out fee, whether it's a leak near an open lawn or one under pool decking or a driveway. If a repair is then needed once the leak's found, that's quoted separately and agreed with you before that work goes ahead.
What are the signs of a hidden water leak?
An unexplained rise in your water bill, a damp or unusually green patch of lawn or garden bed, a hissing sound near pipework, or a water meter that keeps ticking over when every tap and appliance is off. In a pool, the classic sign is water loss that's clearly more than evaporation - worth checking against a simple bucket test before assuming it's the pool shell rather than the plumbing.
How do you tell if a leak is in the pool or the house plumbing?
We isolate the pool and its equipment from the household water supply and test each separately. That tells us whether the water loss is coming from the pool shell, the pool's own pipework, or a completely separate leak in the house lines - which matters, because the fix is different for each.
Do you dig up the garden or pool area to find a leak?
Not to locate it. Acoustic and thermal equipment lets us pinpoint the leak without test-hole digging. Once we know exactly where it is, we'll talk you through what the repair itself involves - which in a lot of cases is relining or a targeted repair rather than a full excavation.

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.
