 Trustindex verifies that the original source of the review is Google. 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

 Trustindex verifies that the original source of the review is Google. We experienced a leak in our pool and were unsure of its source. After reaching out to Core Leak Detection, they utilized their impressive tools to identify two specific areas where the leaks were happening. A different team came a few days later to repair the identified problem areas. They not only addressed the leaks but also inspected for any similar or additional leaks. I wholeheartedly recommend this company for their thorough approach to detecting and repairing pool leaks.

Methods that we use to detect a leak

Tracer Gas

Tracer gas gets inserted into supply lines and will escape through any outlet on a pipe. We can then use a sniffing device to detect where the gas is coming from.

Acoustic

An electronic listening device is used to detect leaks by characterizing and differentiating leak sounds from normal pressurized pipes.

Thermal Imaging

Thermal imaging is used to take images of hot water pipes that are leaking as well as detecting moisture in walls, floors and ceilings.

Moisture Meter

Moisture meters play an important part if a leak cannot be traced. Ideal to determine any waterproofing failures on balconies and soffits.

“At Core Leak Detection, we believe that our clients should get their money’s worth. That is why we will always confirm a leak using at least two of our methods, unlike many leak detection companies that only use a single method. This is simply one of our ways of ensuring that you always receive the best service and great results.”
