Leak Detection in the Hills District
In the Hills District, most concealed leaks hide under something expensive. Homes in Castle Hill, Kellyville, Bella Vista and Glenhaven sit on large blocks with long private water mains running beneath driveways, paved entertaining areas, pools and established landscaping, so an underground leak can waste water for months without ever surfacing. Slab-on-ground construction across the newer estates means hot water lines run inside the slab, where a pinhole shows up as a warm patch of floor or an unexplained bill rather than a visible drip. Out at Dural and the semi-rural fringe, leaks on tank and pump systems drain storage the household depends on. We test, listen and thermally image before opening anything, so the driveway stays intact.

How we handle leak detection in the Hills District
1. Isolate and pressure test
We shut off sections of the system and watch the meter and gauge. That confirms there really is a leak, tells us whether it is on the hot or cold side, and narrows it to a section of the property before anything is opened up.
2. Acoustic and thermal location
Acoustic equipment listens for the sound of water escaping under slabs and paving, while thermal imaging shows temperature patterns through floors and walls. Together they pinpoint the leak rather than leaving us to guess a metre either way.
3. Non-destructive access
Once the leak is marked, we open the smallest area that lets us reach it, whether that means a single tile, a small slab core or a neat wall access panel, instead of demolishing a bathroom to find one pipe.
4. Repair and verify
We repair the failed section, re-pressurise the system and re-check the meter with everything closed. You get a report showing where the leak was, what caused it and confirmation the system now holds pressure.
Every job is quoted on site and agreed in writing before work starts, so there are no surprises.

Recent leak detection jobs in The Hills District
Driveway main leak, Castle Hill
A meter turning with all taps off pointed to the private main. Acoustic tracing located the split beneath a paved driveway. We lifted three pavers, repaired the pipe and relaid them rather than cutting the drive.
Slab leak, Kellyville
A warm patch on a tiled hallway floor turned out to be a failed in-slab hot water line. Thermal imaging pinpointed it, and we cored a single small access, repaired it and reinstated the tile.
Tank supply loss, Dural
A rural property lost tank water overnight with no visible cause. Pressure testing isolated a split in the buried line to the house, which we located, exposed at one point and repaired.
