Quick answer

Wet-area leak detection in Sydney typically starts at a fixed first-hour rate — ours is $299 inc GST — confirmed before any work begins. Beyond the first hour, the cost depends on where the leak is, how hard the area is to access, how hidden the source is, and whether you need a documented report.

What you’re actually paying for

A leak detection fee isn’t just someone looking at a stain. You’re paying for a specialist who does wet-area detection every day, professional equipment (thermal imaging and calibrated moisture meters), and — most importantly — a pinpointed source and a clear answer, usually with no demolition. Done well, that saves you from paying to repair the wrong thing.

What moves the price

Beyond the first hour on site, a few things affect the total:

Where the leak is — a shower recess, a balcony membrane and a pool shell are very different jobs.
Access — tiles, render, slabs and tight cavities take longer to read than an open surface.
How hidden the source is — a visible drip is quick; a concealed leak needs more tracing.
A documented report for strata or insurance adds time over a verbal result.
After-hours or weekend call-outs for an active leak carry a set surcharge.

Why it usually saves money

The most expensive leak is the one that gets ‘fixed’ in the wrong place. Re-tiling a shower, re-rendering a wall or digging up a pool surround on a guess can cost thousands — and if the real source is somewhere else, you pay again. Finding the actual source first is what makes the repair stick. See our full leak detection cost breakdown for how pricing works on a job.

Why do prices vary between companies?
