Leak Detection in Johannesburg & Midrand
A hidden leak can waste thousands of litres a month, lift your municipal water bill and quietly undermine your foundations. We locate leaks accurately before anyone picks up a hammer — then repair them properly.
Find the leak. Fix the cause. Stop the bill.
Johannesburg's water infrastructure is under pressure, and municipal charges for leaked water are unforgiving. A 2mm crack in a buried pipe can waste tens of thousands of litres in a billing cycle while the surface above it stays dry. Chasing that leak with a pickaxe damages paving, walls and gardens — which is why detection comes first.
We start with the evidence: your meter readings, your water bill, damp patches, warm floors, the sound of running water when everything is off. Then we test the system in sections, listen for the leak acoustically and check for moisture and pressure loss until we can point to a specific spot. Only then do we open the smallest possible area and repair it. You get a clear explanation of what failed and what we did about it.
What is included

- Acoustic listening and moisture readings at suspect points
- Leak location marked and explained before opening anything

- Photographs and a written summary of what was found
- Site cleaned up and made good
What we do for Johannesburg homes and businesses
Hidden leak detection
Pinpointing leaks behind walls, under floors and above ceilings using acoustic listening, moisture readings and sectional isolation.
Slab and under-floor leaks
Locating leaks beneath tiled or concreted floors without demolishing the room, then rerouting or repairing the line.
Underground and garden leaks
Tracing buried water lines across lawns, driveways and paving to find the failure point accurately.
Pool leak detection
Distinguishing between evaporation, splash loss and a genuine pool shell, fitting or pipe leak, and recommending the right repair.
Municipal meter and supply leaks
Checking the meter-to-house line, isolating irrigation and outbuildings, and confirming whether the loss is on your side of the meter.
Roof, ceiling and damp diagnosis
Tracing water ingress back to its true source, whether that is a geyser, a failed waterproofing membrane, a balcony drain or a leaking shower.

How to tell you have a hidden leak
One sign on its own can be coincidence. Two or more together almost always means water is escaping somewhere it should not be.
Your water bill jumped
A sudden increase with no change in usage is the most common first sign of a hidden leak.
The meter keeps turning
With every tap closed and no appliances running, a moving meter means water is escaping somewhere.
Damp patches or bubbling paint
Walls and ceilings that stay damp, blister or show tide marks usually have water travelling behind them.
Warm patches on the floor
A warm spot on a tiled or concrete floor often points to a leaking hot water pipe beneath it.
The sound of running water
Hissing or trickling when everything is off is a strong indicator of a pressurised leak.
Sinking paving or soft grass
Ground that has settled, or a permanently soggy patch of lawn, is classic evidence of an underground burst.
Musty smells or mould
Persistent damp smells in a room with no obvious source deserve investigation before mould spreads.
Unexplained low pressure
A leak on your supply line can drop pressure at the taps furthest from the meter.
