Hidden water leaks can cause thousands of dollars of damage before they're found. Mr. Clog uses acoustic leak detection and thermal imaging technology to locate leaks inside walls, under slabs, and underground — with minimal disruption to your property.

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 and thermal cameras 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

Signs include unexplained water bill increases, damp patches on walls or ceilings, the sound of running water when taps are off, and mould growth.

We try to avoid it. Our detection technology locates the leak precisely so any access is minimal and targeted.

Yes — this is one of our specialities. Slab leaks are detected acoustically and confirmed with pressure testing.

We provide one transparent quote covering detection and repair. No hidden fees.
