Leak Detection in Northern Sydney
Northern Sydney's older housing makes concealed leaks unusually common. Federation and interwar homes in Lane Cove, Hunters Hill, Wahroonga and Gladesville still carry sections of galvanised steel and early copper that corrode from the inside, so leaks begin as pinholes deep inside wall cavities or under suspended timber floors. Sloping bushland blocks add a complication: escaping water follows the fall and appears in a subfloor or garage well downhill of where the pipe actually failed, which is why guessing from the wet patch so often leads to unnecessary demolition. In Chatswood, North Sydney and Epping apartments, a leak from one unit shows in the ceiling of another and needs proving before strata will act. We locate accurately first.

How we handle leak detection in Northern Sydney
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 Northern Sydney
Cavity leak, Lane Cove
A stain spread across a hallway ceiling with no fixture above it. Thermal imaging traced the water uphill to a pinholed steel pipe in a wall cavity. We opened one access panel and replaced the corroded run.
Downhill subfloor water, Hornsby
Water pooled in a subfloor on a sloping block. Pressure testing showed the loss was on the cold line near the front of the house, not where the water sat. One targeted repair fixed it.
Unit ceiling leak, Chatswood
A lower apartment had recurring ceiling damage. We isolated units above and pressure tested until the failing shower waste was identified, then gave strata a written report for the repair approval.
