Why leaks are hard to find in Hornsby
Hornsby is the main centre of Hornsby Shire, about 23 km north-west of the Sydney CBD. About 22,500 people live here (2021 Census). It is known for Hornsby station, where the North Shore and Northern lines meet, Westfield Hornsby, the Hornsby Water Clock and Hornsby Aquatic Centre.
Almost six in ten homes are apartments, many in medium and high-rise blocks near the station, where risers, balconies and shower membranes are shared and a leak can travel into the unit below or the car park. Federation and older houses on the surrounding streets have ageing pipes under timber floors, and sloping blocks let an underground leak drain away. The first sign is often a stained ceiling, water in a car park, damp walls or a higher water bill. We find the exact source, so only a small area needs to be opened for the repair.

High Sydney Water bill?
Sydney Water supplies Hornsby and is responsible for pipes up to your meter. Leaks on your side of the meter are the owner's responsibility. If a hidden leak has pushed up your bill, Sydney Water's hidden leak allowance can credit 50% of the water usage charge for the most affected quarter, once every five years per property. Our report shows where the leak was and what caused it, which supports your application. Download our free leak credit claim checklist.

Hornsby leak detection FAQs
How much does leak detection cost in Hornsby?
It starts from $398 inc. GST for the first hour on site, including thermal imaging, acoustic and tracer gas equipment and an insurance-ready PDF report. Extra time, if needed, is $168 per hour. Most single leaks are found within the first hour, and we give you a free phone quote before we book.
How do I know if I have a hidden water leak?
Turn off every tap and water-using appliance, then check your water meter. If the dial is still moving, water is escaping somewhere. Other signs include a higher Sydney Water bill, damp walls or skirting boards, a musty smell, mould or warm spots on a tiled floor.
Do you offer emergency leak detection in Hornsby?
Yes. Our emergency line runs 24/7 on 1300 346 353. Same-day appointments are often available across Hornsby, Waitara, Asquith and Hornsby Shire.
Water is coming through my apartment ceiling. Who pays to find it?
It depends on where the leak starts. We test the apartment above, its shower, bath waste, balcony and the building's riser pipes, and our report shows the exact source. The owners corporation and owners use it to work out who is responsible and to support any insurance claim.
Can you work in a high-rise with the building manager?
Yes. We arrange access with the building manager and nearby unit owners, test showers, bath wastes, riser pipes and balconies, and send a clear report on the source to the owner, manager or body corporate.
Will my report help with an insurance claim or a high water bill?
Yes. Every job includes a PDF report with photos, readings and the cause of the leak. Insurers use it to assess resultant damage claims, and it supports an application to Sydney Water for help with a bill caused by a hidden leak.
