Leak detection

Leak Detection Perth

Find the leak before it finds your floor. Acoustic and thermal detection across pipes, slabs and concealed walls.

Leak detection in Perth by Dawson's Plumbing

What we do

We find leaks without tearing your house apart. Acoustic listening picks up the pressurised hiss of a water leak through tile, slab or wall. Thermal imaging picks up the temperature signature of a hot water leak before it surfaces. Combined with pressure testing on the main, we usually pinpoint a leak within a tile or two before any cutting starts.

How we work

A typical detection call:

  • Isolate the system. Confirm there's actually a leak and where in the system.
  • Acoustic survey. Walk the suspected zone with listening gear.
  • Thermal imaging where applicable.
  • Mark the spot and discuss repair options.
  • Quote the repair. You decide whether we proceed today.

Pricing, what to expect

Detection itself is a fixed call-out price for a standard residential job. Repair is quoted separately once we've found the leak, so you can decide on the spot. If we can't find the leak, we tell you straight, no charge for time wasted.

Areas we serve

All Perth metro. Slab leaks are particularly common through Cockburn, Baldivis, Joondalup and Kalamunda where slab-on-ground construction is the norm.

Common questions

Can you find a slab leak without breaking the floor?
Most of the time, yes. Acoustic and thermal usually narrows it down to a tile or two. Then a small, targeted cut rather than ripping up the whole floor.
How do I know if I've actually got a leak?
Common signs are a creeping water bill, warm patches on a floor, damp patches on walls, or the meter ticking over with everything turned off. Any of those, ring us.
Do you fix the leak the same day?
Usually, yes, if parts are common. If it's an unusual fitting we'll source it and book a return visit.
