Which leak you have
The kind of leak decides who you call and how the search is done. A few checks before the technician arrives help.
- Check the meter
- Turn off every tap and water point inside and outside the house, then look at the water meter: if the dial still moves, water is leaking somewhere.
- Stormwater leak
- A leak that shows only when it rains is most likely a stormwater leak.
- Sewer drain leak
- A leak with a foul smell usually points to a leaking sewer drain.
- Mains supply leak
- Water bubbling up from the ground is most likely a leak on the water supply pipe.
- Pool leak
- Topping up the pool often, wet or soggy ground around it, cracks in the shell, paving that lifts or sinks and air bubbles at the inlet are the signs of a pool leak.

First review: They were willing to help sooner when I had an emergency, and this really made all the difference to save costs and serious inconvenience for my tenant. Thank you to the team for being so accommodating. Second review (a year later) : We called them back a second time because there were new leaks that popped up after the first 2 leaks were fixed a year ago. Our pool water was literally disappearing! These were very bad leaks due to the inadequate pipe system that was put in by either the developer or the previous owner (not sure which). We decided to completely redo our entire piping system from the jets to the pump which also included 2 spa jets and from the skimmer box to the pump. After receiving 2 quotes, we went with Core Leak Detection because they provided us with a 3 year guarantee on the work and also they pressure test the system afterwards which is critical to see that everything is working properly. We are extremely glad we did because they definitely went out of their way to make sure this huge project was perfectly done and we would not have any more issues with the pipes and jet system. They also fixed our spa system and filter sand which was a mess. Our coping was beautifully preserved and they made sure they left it in the condition they found it. A special thanks goes to Wayden and George, who both patiently answered all our questions and were always professional, kind and friendly. Your assistance and advice went a long way to calm our fears with regards to this project. We also appreciate you accommodating us on short notice. Also Helicia in the office, your customer service is excellent and communication is really good all round. We always knew where the project was in the process. Been a pleasure working with you all :-) A final note: You cannot go wrong to leave things in this company's capable and reliable hands. We have no hesitation in recommending them for all leak detection, plumbing and swimming pool problems.

Excellent service received from Day 1 from Core Services. My initial telephone call was answered within seconds, which is very rare in today's service industry. The entire process—from booking, leak detection report (pool leak), quotation, repair, and invoicing—was seamless and faultless. The teams arrived on time as scheduled, worked efficiently and neatly, quickly identified the issue, and completed the repair. The entire process was completed within a week. A special thank you to Helicia, Johan, Jaydee, Wayden, and Lucas for their professionalism and excellent customer service. I would highly recommend CORE Plumbing Leak Detection as the go-to company for leak detection and repairs. My frustrations with trying to deal with the issue myself have disappeared along with the leak, and I can now look forward to enjoying my pool again. Best regards, Sean
