Leak Detection Services in Fourways
— Find Hidden Leaks Without Breaking Walls
Unexplained high water bills or damp patches in Fourways? Our specialist leak detection team uses acoustic listening equipment and thermal imaging to pinpoint hidden leaks under floors, behind walls and underground — accurately and non-invasively, before a drop of plaster is touched.
Professional Leak Detection in Fourways
Hidden water leaks are deceptively costly. A small pipe leak under a tiled floor or behind a wall can waste thousands of litres of water per month, dramatically inflate your municipal water bill, and silently cause structural damage, rot and mould over months or years. Many homeowners in Fourways only discover a leak when they receive a massive water bill or notice damp appearing on walls or ceilings.
Our leak detection specialists use professional-grade acoustic listening equipment that amplifies the specific frequency of water escaping under pressure, allowing us to pinpoint the exact location of a leak without cutting into floors or walls. We also use thermal imaging cameras to identify temperature differentials caused by wet areas hidden behind surfaces. This combination of technologies allows us to locate leaks in concealed pipes, under concrete slabs, underground water mains, and swimming pool plumbing across Fourways and surrounding areas.
Once the leak is located, we provide a detailed written report including the exact location, suspected cause, and our recommended repair method. In most cases we can then carry out the repair on the same visit, minimising total disruption to your property. Our non-invasive approach means we only open up your walls or floors where the leak actually is — not guessing along an entire pipe run.

How Our Leak Detection Process Works
-
Initial Assessment & Pressure Testing
We begin with a full assessment of your plumbing system — checking water meter readings to confirm water is being lost, isolating zones to narrow down which section is affected, and performing a pressure test to confirm a leak is present in the concealed pipework. This prevents unnecessary detection work on systems that may have a simple visible leak elsewhere.
-
Precision Detection Sweep
Using acoustic listening equipment along the pipe route, our technician systematically narrows down the leak location by comparing sound levels at multiple points. Thermal imaging is applied to walls and floors in the suspect zone to visually confirm the presence of moisture. Together, these technologies allow us to mark the exact leak position on your floor or wall, accurate to within a few centimetres.
-
Report, Repair & Confirm
We provide a written report documenting the leak location, estimated cause, and recommended repair. With your approval, we carry out a targeted repair — opening only the minimal area needed to access the leak, fixing the pipe, and confirming the repair holds with a follow-up pressure test. We leave your property as tidy as possible and provide repair documentation for your insurer.
Leak Detection FAQ
My water bill is very high but I can't see any obvious leak. What should I do?
A sudden or gradual increase in your water bill is one of the most common signs of a hidden leak. Start by doing a simple check: turn off all taps and water-using appliances in your home, then look at your water meter. If the dial is still moving, water is escaping somewhere in your system. Also check your toilet cisterns — a constantly running toilet can waste up to 400 litres per day without making any obvious noise. If the meter confirms a leak but you can't find it, call us for a professional leak detection assessment in Fourways.
How accurate is acoustic leak detection?
In ideal conditions — a straight pipe run under a hard floor with good pipe-to-surface contact — modern acoustic leak detection is accurate to within 5–10 cm. Accuracy can be affected by factors like pipe material (plastic transmits sound less well than copper), soil type, depth, and background noise. In difficult cases, we combine acoustic detection with thermal imaging and tracer gas methods to achieve greater precision. In the vast majority of jobs in Fourways, we locate the leak before any surfaces are opened.
Can you detect leaks under a concrete floor or paving?
Yes — under-slab leak detection is one of our most common requests in Fourways, where many properties have pipes running under concrete screeds or tiles. Our acoustic equipment is specifically designed for this type of detection. In most cases we can locate the leak accurately without breaking up any concrete. Once found, we open only a small, targeted access point directly over the leak rather than trenching along the entire pipe run — saving significant time and reinstatement costs.
What are the signs I might have a hidden leak in my Fourways home?
Common signs of hidden leaks include: unexpectedly high water bills with no change in usage; damp or discoloured patches on walls, ceilings or floors; the sound of running water when all taps are closed; reduced water pressure at taps or showers; cracks in walls that are expanding over time; musty or mouldy smells in rooms; warm spots on cold floors (which can indicate a hot water pipe leak); and constantly wet soil in one area of your garden with no irrigation explanation. If you notice any of these, call us for an assessment.
