Licensed & Insured Plumbers
Every leak detection job is carried out by fully licensed, insured plumbing professionals you can rely on.
For two decades, The Gap Plumbing & Drains has helped homeowners and business owners across The Gap track down hidden water leaks before they turn into costly damage. Our technicians combine acoustic listening devices, thermal cameras and moisture meters to pinpoint leaks under slabs, behind walls and beneath timber floors without unnecessary demolition. We understand the ageing galvanised, copper and poly pipework common throughout The Gap and greater Brisbane, so we know exactly where pinhole leaks, cracked joints and worn isolation valves are most likely to hide. Locals trust us because we explain what we find, hand over a written report and only open up the section of pipe that genuinely needs repair.

The Gap Plumbing & Drains offers dedicated leak detection across The Gap and throughout Brisbane, using non-invasive technology to locate the exact source of a leak before any digging or demolition begins. Whether you've noticed a spinning water meter, an unexplained spike in your water bill, or a damp patch appearing on your lawn or driveway, our team can trace the problem back to its source. We service homes and businesses throughout Brisbane, from older character homes with ageing copper and galvanised pipework to newer builds running on poly and PEX plumbing.
If you're dealing with a persistently high water bill, a musty smell under the floor, or water pooling where it shouldn't be, don't wait for the problem to get worse. Give our friendly team a call on {{phone_number}} and we'll arrange for one of our leak detection specialists to visit your The Gap property. Catching a leak early means less disruption, lower repair costs and far less water wasted while the problem goes unnoticed.
A hidden water leak rarely announces itself outright. Instead, you might notice a warm patch on your tiled floor, a section of lawn that stays soggy even in dry weather, or a water bill that has crept up with no obvious explanation. These are often the first signs of an underground water leak, a slab leak, or a pinhole forming in old copper pipework.
Left undetected, a leaking pipe can undermine a slab, rot timber framing, encourage mould growth and waste a considerable amount of water. Leaks behind walls or under a shower can travel a surprising distance before showing up as a stain on the ceiling below, which is why an upstairs leak doesn't always mean the problem is upstairs at all.
It isn't always easy to tell whether you're dealing with a genuine plumbing leak, a sewer leak, stormwater seepage or simple condensation. That's where proper leak detection equipment, rather than guesswork, makes all the difference in getting the right fix the first time.
The Gap Plumbing & Drains combines several proven leak detection methods to find the precise source of a leak, rather than relying on guesswork or unnecessary excavation. Our approach is tailored to your property, whether that's a slab leak under a brick home in The Gap or a leaking riser inside a strata unit.
We also check common trouble spots such as leaking stop cocks, ageing water heaters and failed shower waterproofing, since these are frequently mistaken for a hidden slab or wall leak. Once the leak is marked, we'll walk you through our findings and provide a written report, then carry out the repair, whether that's a patch, a section replacement or a broader repipe, so you're only paying to open up the part of the pipe that's actually failed.
Leak detection often goes hand in hand with a handful of other plumbing services. Here's how we can help once the source of your leak has been found.
We've refined our leak detection process over many years in the plumbing trade to be as accurate and non-invasive as possible. Rather than jumping straight to excavation, we start by listening, testing and mapping to narrow down exactly where a leak is hiding. This structured approach saves The Gap homeowners time, money and unnecessary damage to their property, and we'll talk you through your options before any work begins.
We assess your water meter, plumbing history and any visible signs to narrow down where the leak may be located.
Using acoustic, thermal or tracer gas equipment, we pinpoint the exact spot the leak is coming from.
We provide a written report of our findings, then repair the leak or advise on the best long-term fix.
