Most leaks we trace in Bondi are apartment leaks. Much of the suburb is Art Deco and post-war blocks, so a failed flexible hose, a leaking hot water unit or a shower that has lost its waterproofing shows up in the ceiling of the apartment below, often a long way from where it started. Salt air means fittings here give way earlier than owners expect.

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.

Water from a failed flexi hose under a vanity or sink, or from a shower upstairs, can travel along the slab before it shows. The stain is rarely directly under the leak. Finding the true source first stops two owners paying for the wrong repair.

Tapware, external pipework and hot water units corrode faster this close to the ocean. A slow weep at a corroded fitting can run for weeks inside a wall or cupboard before it is noticed.

In a block, whether a leaking pipe belongs to one owner or to the strata scheme decides who pays. A written report with the located source gives the owners and the committee the same facts.

Fixed price quoted before we start. $0 call-out fee.

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

Either owner or the strata manager can book us. We trace the leak to its source, often a failed flexible hose or a shower upstairs, and give everyone involved the same written findings so the right owner fixes it.

Usually. We pressure test the lines, listen for the leak acoustically, and use thermal imaging and dye testing to narrow it down before anything is opened up.

Yes. We provide written reports, and camera footage where drains are involved, so the committee has something definite to act on.

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