Leak Detection on the Northern Beaches
Salt corrosion makes the Northern Beaches a leak detection hot spot. Copper pipe in Manly, Dee Why, Collaroy and Avalon pits from the outside in coastal air, and the resulting pinhole leaks are small, slow and completely hidden until a ceiling stains or a bill spikes. Sandy ground around Narrabeen and Warriewood swallows escaping water without any surface sign, so underground main leaks can run for months, and a high water table makes it hard to tell plumbing water from groundwater without proper testing. Steep peninsula blocks send leaks travelling well away from the source, and holiday homes left empty give small leaks weeks to do serious damage. We confirm the loss at the meter, then locate acoustically and thermally.

How we handle leak detection on the Northern Beaches
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 Beaches
Pinhole leak, Collaroy
A ceiling stain grew slowly with no fixture above. Thermal imaging found a salt-pitted hot water line in the wall behind. We opened a small access, replaced the corroded run and protected the new pipework.
Buried main leak, Narrabeen
A bill tripled with nothing visible in sandy ground. Meter testing confirmed constant loss and acoustic tracing located the split under a garden bed, which we exposed at one point and repaired.
Empty holiday home, Avalon
An agent reported an unexplained meter reading at a vacant house. We attended with authority, isolated and pressure tested the system, found a failed in-wall connection and repaired it before the damage spread.
