Leak detection across Sydney
We cover metro Sydney from the Northern Beaches and North Shore to the Eastern Suburbs, the Inner West, the Hills and Western Sydney, plus Wollongong. Our Sydney technician is based in Seaforth, so the Northern Beaches and lower North Shore are often same-day.
Sydney leaks have their own patterns: shower and balcony leaks into the unit below in strata buildings, roof and parapet flashing leaks in older terraces, slab leaks in newer homes, and long underground supply lines on larger blocks. Most of Greater Sydney is supplied by Sydney Water, and our report can support a claim for its hidden leak allowance.

Leak detection Sydney FAQs
How much does leak detection cost in Sydney?
$398 inc. GST for the first hour on site, then $168 per hour if more time is needed. The written report is included. If we can't find the leak, you don't pay for the inspection.
How quickly can you come out in Sydney?
Same-day visits are often available, especially on the Northern Beaches and North Shore where our technician is based. The 24/7 line on 1300 346 353 is for burst pipes and gas leaks.
Can you find a leak without breaking tiles or digging up the yard?
Usually, yes. Pressure testing, acoustic listening, tracer gas, thermal imaging and moisture mapping pinpoint most leaks, so the repair is one small opening in the right place.
Do you work with strata managers and owners corporations?
Yes. We trace leaks between units and from balconies, roofs and common property, and send a written report the strata manager, owners corporation and insurer can act on.
Will my report help with a Sydney Water leak allowance?
It can. Sydney Water may credit part of a bill pushed up by a hidden leak once it's repaired. Our report records where the leak was and what caused it, which supports the application.
Do you repair the leak as well?
Yes, if you'd like us to. Our first visit is about finding the leak: we mark it, explain the cause and give you a report. Many plumbers, builders and property managers then do their own repairs. If you want us to fix it, we'll quote the repair and return at another time to complete it, often with trusted independent trades.
