Avg. rating of 7 reviewsFor two decades, Dulong Plumbing & Drains has helped homeowners and business owners across Dulong and the wider Sunshine Coast region pinpoint hidden water leaks before they turn into costly repairs. Our licensed plumbers use acoustic listening equipment, thermal imaging and non-invasive tracer gas methods to locate leaking pipes under slabs, in walls and beneath timber floors without unnecessary digging or demolition. We've worked on everything from a single spinning water meter at a Dulong acreage property to full strata leak detection reports for local commercial buildings. That depth of hands-on experience means we find the source of a leak quickly, explain it clearly, and repair it properly the first time.
Every leak detection job is carried out by fully licensed, insured plumbing professionals.
We use acoustic, thermal and tracer gas equipment to find leaks without guesswork.
You'll know the cost of your leak detection before any work begins, with no hidden extras.
Two decades spent finding and fixing hidden leaks across Dulong and the Sunshine Coast.
Dulong Plumbing & Drains provides professional leak detection across Dulong and the wider Sunshine Coast area, using non-invasive technology to locate hidden water leaks in slabs, walls, ceilings and underground mains. Whether you've noticed a spinning water meter, an unusually high water bill, or a damp patch appearing in the yard or under the house, our team can trace the problem back to its source without unnecessary digging or demolition. We service homes tucked into the hinterland around Dulong as well as commercial and strata properties throughout the region.
If you suspect a hidden leak, don't wait for it to worsen. Untreated leaks can undermine slabs, rot timber framing and inflate your water bill month after month. Give our team a call and we'll arrange a time to inspect your property, run isolation tests where needed, and locate the exact position of the leak using acoustic and thermal equipment. Once we've marked the leak, we'll talk you through the repair options and provide a fixed price before any work starts, so you always know where you stand.
A hidden water leak rarely announces itself straight away. It might show up as a slab that's warm underfoot in one spot, a section of lawn that stays soggy no matter the weather, or a water meter that keeps ticking over even when every tap in the house is off. Older homes around Dulong with ageing copper hot water lines are particularly prone to pinhole leaks caused by pitting, while newer builds can develop leaking shower waterproofing or cavity pipe leaks behind tiled walls.
Left undetected, these leaks can quietly cause serious damage. Timber floors can swell and warp, plasterboard ceilings can stain and sag, and concrete slabs can crack under sustained moisture. An unexplained spike in your water bill is often the first real clue that something's wrong underground or within your wall cavities, and because many Dulong properties sit on sloped or acreage blocks, distinguishing a genuine mains water leak from stormwater runoff or sewer seepage takes an experienced eye.
Whether it's a suspected slab leak under a concrete floor, a leaking isolation valve in the meter box, or water pooling near a driveway, getting an accurate diagnosis early prevents small problems from turning into major structural repairs.
At Dulong Plumbing & Drains, we combine proven acoustic listening equipment, thermal cameras and tracer gas technology to locate leaks accurately before we lift a single tile or open a wall. This non-invasive, no-smash approach means less mess, less cost and a faster path to repair for Dulong homeowners and business owners.
Once we've marked the exact location of the leak, our licensed plumbers can carry out the repair on the spot, whether that's a patch repair, a section of pipe relining, or a full copper repipe where pitting has become widespread. You'll receive a clear, fixed-price quote before any repair work begins.
Leak detection is often just the first step. If we uncover a blocked drain, a failing sewer line or ageing pipework while tracing your leak, our team can handle the full repair on the same visit.
We've refined our leak detection process over 20 years to be thorough, minimally invasive and easy to understand from start to finish. Each step is explained clearly so you know exactly what we're checking and why, and you'll never be left guessing about cost or next steps. From the first phone call to the final repair, our Dulong-based plumbers keep communication straightforward and honest.
We start with a full inspection and isolation test to confirm where water is escaping and rule out fixtures like toilets or irrigation.
Using ground microphones, correlators and thermal cameras, we trace the leak to its exact position under the slab, in the wall or underground.
Once marked, we repair the leak or recommend the best long-term fix, backing it with a written report if needed for insurance.
