Don't let unseen leaks damage your property.
Water leaks are often invisible to the naked eye, hidden behind walls, under concrete slabs, or deep underground. By the time physical signs like damp spots or pooling water appear, significant structural damage may have already occurred.
At Flow Vision Projects, we utilize state-of-the-art non-destructive technology to accurately trace and pinpoint the exact location of leaks. This service saves you from the massive costs of "guesswork" digging and unnecessary property destruction.
Schedule a Detection ServiceSigns You Have a Hidden Water Leak
If you notice any of these symptoms, you likely have an undetected leak that is costing you money and causing structural damage right now.
Unexplained High Water Bills
A sudden spike in your municipal water account is the number one indicator of a hidden underground or in-wall water leak on your property.
Damp Spots on Walls or Floors
Unexplained moisture patches, bubbling paint, or warping skirting boards indicate water is migrating through your building structure from a hidden source.
Spinning Water Meter
If your water meter dial continues spinning when all taps and appliances are turned off, water is flowing somewhere it shouldn't be.
Hissing Sounds Behind Walls
A faint hissing or rushing sound inside walls or under floors when no water is running is a telltale sign of a pressurised pipe leak.
Advanced Leak Detection Technology
We don't guess and smash. Our specialist equipment locates leaks with pinpoint accuracy through concrete, tiles, and underground—without destroying your property.
Acoustic Listening Devices
Ground microphones and electronic amplifiers detect the exact sound frequency of pressurised water escaping from pipes under concrete slabs and underground.
Thermal Imaging
Infrared cameras reveal temperature differentials caused by water migration behind walls, under floors, and in ceiling voids—making invisible leaks visible.
Tracer Gas Detection
A safe, non-toxic gas is introduced into the pipe system. Sensitive detectors on the surface pinpoint exactly where the gas escapes—confirming the leak location.

Frequently Asked Questions About Water Leak Detection
Expert answers to urgent questions about hidden leaks, high water bills, and detection services in Gauteng.
A sudden spike in your municipal water bill almost always indicates a hidden water leak on your property. Underground leaks, burst geysers, or toilet cistern faults can waste thousands of litres unnoticed.
Professional leak detection pinpoints the exact source so it can be repaired immediately—stopping the financial bleed and preventing further structural damage to your home or building.
We use advanced acoustic listening devices, thermal imaging cameras, and tracer gas technology to detect leaks through solid surfaces non-destructively. These methods accurately locate the leak point so only a small, targeted repair is needed.
This saves your floors, walls, and landscaping from unnecessary destruction—unlike traditional "guess and smash" plumbing methods.
Many South African insurance policies cover leak detection as part of a valid water damage claim. Flow Vision provides detailed, industry-standard reports with photographic and video evidence that are accepted by all major insurers.
We recommend contacting your insurer first to confirm coverage, then booking our service. Our reports are formatted specifically to support successful claim submissions.
Pricing depends on property size, the number of suspected leak points, and access complexity. Flow Vision provides transparent quotes after a free initial assessment for all leak detection projects across Gauteng.
Our rates are competitive for both residential and commercial properties, and the cost of detection is a fraction of the damage caused by an undetected leak running for weeks or months.
We service Johannesburg, Pretoria, Centurion, Midrand, Sandton, Ekurhuleni, East Rand, West Rand, and all surrounding Gauteng regions. We also deploy nationally for commercial and industrial projects.
Our leak detection teams are on the road daily, so same-day and next-day bookings are frequently available for urgent cases.
Most residential leak detections are completed within 1–3 hours depending on property size. Commercial and industrial sites may take longer due to pipe network complexity.
We provide same-day reporting with HD video evidence on every job, so you can brief your plumber or insurer immediately after our visit.
