Leaks in the Parramatta CBD split the same way its buildings do. In the towers, water from one apartment reaches the floors below, and the first job is working out whether the source is private or common property. In the older streets around it, reactive clay moves the ground and stresses pipes over the years.

The same dye coming up through the floor outside the bath. Where it surfaces is where the water is escaping — no floor lifted to find it.

In a high-rise, a failed hose, shower or hot water unit upstairs shows in the ceiling below, and building management usually needs to be involved before anything is isolated. Finding the true source settles who repairs it.

Whether a leaking pipe belongs to one unit or to the building decides who pays for the repair and the damage. A written report with the located source gives strata something definite to act on.

Reactive clay through the surrounding streets swells and shrinks with the weather, which cracks pipes and separates joints over the years. A water bill that climbs, or a meter that moves with everything off, is the first sign.

How It Works

01

We discuss your symptoms — high water bills, damp patches, mould — to narrow the search area.

02

We use acoustic listening devices, thermal cameras, moisture readings and, where it suits, tracer dye to pinpoint the leak non-invasively.

03

We provide a clear report of the leak location and recommend the repair approach.

04

We carry out the repair — patching, pipe replacement, or relining as appropriate.

Common Questions

It depends where the leak is. If it is in a fixture or pipe that serves only your apartment it is generally yours; if it is in common pipework it is usually the owners corporation's. We locate it precisely so nobody is guessing.

Yes. We give a written report of what we tested, where the leak is and what it needs.

Usually. Pressure testing, acoustic listening, thermal imaging and dye testing narrow it down to a small area before anything is opened.

How we find hidden leaks, the signs to look for, and what it involves.
