Leak Detection

A hidden leak rarely announces itself with a puddle. It shows up as a water bill that doesn't make sense, a damp patch that won't dry, or a lawn that's greener than it should be. We use acoustic listening equipment and thermal imaging to trace the exact source before any wall, floor, or slab gets opened — so you pay for a repair, not a demolition.

How to tell

Signs you might need this

Your water bill has jumped 20–50% or more with no change in usage
A patch of lawn or paving stays damp when the rest of the yard is dry
You can hear running water when every tap in the house is off
Damp patches, bubbling paint, or a musty smell on an internal wall
Your water meter is still ticking over with every tap closed and no appliances running

How it works

Our process

01

Isolate

We shut off zones one at a time to narrow down which line the leak is on.

02

Trace

Acoustic and thermal equipment pinpoints the leak's exact location, usually within centimetres.

03

Confirm & quote

We mark the spot, explain what we found, and quote the repair before opening anything.

What's included

  • Full-property water audit if the source isn't obvious
  • Acoustic leak detection equipment
  • Thermal imaging for leaks under slabs or behind tiling
  • A written report of what we found, useful for insurance claims

What it costs

As a guide, non-invasive leak detection in Cape Town typically runs R1,200–R4,500 depending on how complex the trace is — a straightforward exposed-pipe leak is at the low end, a slab leak needing thermal imaging is at the higher end. We confirm the exact price before any work starts, and it's credited toward the repair if we do that too.

Questions about this service

Will you need to break tiles or walls to find the leak?

Not to find it — our equipment locates the leak without opening anything. Repairing it may need limited, targeted access, which we'll always quote and explain first.

My water bill went up but I can't see any damage — could it still be a leak?

Yes, this is the most common way a hidden leak shows up. A slab or underground leak can run for weeks without a visible sign beyond the bill.

Can this help with an insurance claim?

Yes — we provide a written report of the leak's location and likely cause, which most insurers accept as supporting documentation.
