The true cost of an undetected commercial leak

On a commercial site a slow leak often hides behind sealed walls, under screed or in an underground supply line for months. By the time it shows, you may be paying for thousands of wasted litres every month and facing damage to floors, foundations or stock. Because commercial plumbing runs at higher volumes and pressures than a home, the losses add up faster — which is exactly why pinpointing the source early is worth doing properly.

How we detect commercial leaks — without the disruption

We combine several non-invasive technologies so we can find the leak without excavating your whole site or shutting you down for days:

• Acoustic testing to hear water escaping under pressure through floors and walls.
• Thermal imaging to reveal temperature differences where water is tracking.
• Tracer-gas testing to pinpoint the exact escape point in pressurised lines.
• Pressure and moisture testing to confirm the source and rule out red herrings.

Every investigation is a process of elimination. Once we’ve isolated the leak we mark it precisely, so any repair is targeted — not a guessing game that turns into an open trench across your parking area.

Commercial and industrial properties we service

We work across offices, retail centres, complexes and body corporates, warehouses, factories, schools and guesthouses throughout Pretoria East, Centurion and serviced Johannesburg suburbs. If you manage a building and your water account has jumped without explanation, that’s usually the first sign worth investigating.

Detection first, then a costed repair

Leak detection is a paid diagnostic callout, not a free quote. Once payment is received we carry out the full test and, within up to two business days, send you a photographic report on our findings together with a repair quote. If we locate the leak, our team can carry out the repair — quoted separately — so you have one accountable specialist from diagnosis to fix.
