Water Leak Detection – Certified Leak Detectors
Leak detection across Johannesburg & Pretoria – every drop of water counts

Clear, upfront pricing: a single flat rate for homes, tailored quotes for complexes.
Signs You May Have a Hidden Leak
Hidden leaks leave warning signs. Be on the lookout for:
Sudden spikes in your water bill
Damp spots, bubbling paint or discolouration
Musty smells or mould growth
Reduced water pressure
Running water sounds when all the taps are closed
Don’t let doubt become damage. A small leak today can be tomorrow’s costly disaster.

Helpful Tips for Property Owners
Acting early protects your home, saves money, and conserves water.
Spotting Early Warning Signs
Check your meter
With all taps closed, watch your water meter. If it still moves, you likely have a hidden leak
Monitor your water bill
A sudden unexplained spike often signals wasted water long before damage appears
Trust your senses
Musty smells or damp patches usually mean water is present where it shouldn’t be
Professional vs DIY
Even a small drip can spread moisture through walls and floors, raising repair costs and creating mould risks.
In case of a sudden burst, turning off the main supply limits damage until help arrives.
DIY shortcuts often cost more in the long run. Professional detection protects your property, lowers repair costs and prevents insurance disputes.
Preventing Costly Damage
Certified leak detectors use advanced tools – acoustic devices, tracer gas, thermal imaging and moisture meters – to pinpoint leaks without unnecessary digging.
Painting over damp patches or sealing cracks only hides the symptoms. The leak will keep spreading until it’s properly fixed.
DIY shortcuts often cost more in the long run. Professional detection protects your property, lowers repair costs and prevents insurance disputes.
