Leak detection in Sandton — what we actually find
In a Sandton apartment a hidden leak usually announces itself in the unit below rather than in yours, and by then the question is which line and whose responsibility. Detection matters here because opening a slab speculatively in sectional title is a permission problem as well as a cost. We locate first and report in writing, so the managing agent has something definite to work from.
Property stock in Sandton
Sandton splits into two very different jobs. The CBD and its surrounds are high-rise sectional title, where pressure is boosted, geysers are often in service ducts and anything invasive needs body-corporate sign-off. The older freehold edges toward Morningside and Sandhurst are 1970s and 1980s homes on original copper that is now well past the age where pinhole leaks start appearing.
Most CBD buildings need access arranged through the managing agent, and work in a duct or riser usually needs the trustees notified. We book those in rather than arriving and waiting at a gate.
Faults that cluster in Sandton
- Pinhole leaks in original 1970s and 1980s copper on the freehold side
- Pressure-control valves failing early on boosted high-rise supply
- Geysers in service ducts with drip trays draining into the slab rather than outside
- Earth bonding missing or broken after past renovations
How leak detection works
The meter test tells you whether you have a leak; detection tells you where it is. Close every tap, note the reading, wait two hours and read again — any movement means water is escaping between the meter and your fixtures. From there, acoustic correlation and thermal imaging locate it precisely enough to repair without opening tiles speculatively. That precision is the whole point, because the repair is usually small and the exploratory damage is what costs.
- Acoustic and thermal detection on supply lines, including under slabs and paving
- Toilet and cistern dye testing, which finds the most commonly missed silent leak
- Irrigation, pool and buried supply-line isolation testing
- Written reports with marked locations for insurance and municipal leak adjustments
- Repair of the located leak, or re-routing where the buried run is at end of life
Our process on a Sandton call-out
- 1Confirm an active leak with a meter isolation test before any equipment comes out
- 2Isolate zone by zone — toilets, irrigation, pool, house — to narrow the area
- 3Pinpoint with acoustic correlation and thermal imaging
- 4Mark the location and report it in writing with the position recorded
- 5Repair with a targeted break-out rather than exploratory demolition
