A water leak is confirmed at the meter and located with equipment. Those are two separate jobs, and most of what you pay for is the second one.
Detection is diagnostic. A specialist marks the spot, then repair is quoted separately. Full scope sits under Leak Detection Cape Town.
Send your meter reading with all taps closed, plus a photo of any damp patch.

Close every tap and outlet, then watch the meter for 15 minutes. If the dial still turns, water is escaping somewhere on your side of the connection. That single test tells a specialist whether to bring acoustic gear or start at the geyser.
How Leaks Are Found
- Acoustic correlation - pressurised pipes hiss at the break. Ground microphones locate it through paving and slab.
- Thermal imaging - hot water lines show as a heat signature through tiles and ceilings.
- Pressure testing - isolates a section and proves whether it holds.
- Tracer gas - hydrogen-nitrogen pushed through the empty line and picked up at the surface. Used when acoustics fail.

These are indicative market ranges, not a quotation. They are compiled from published South African leak detection and plumbing pricing to give you a starting point for budgeting. They are not the rate card of any company on this platform.
Detection is charged for the diagnosis, not the outcome. A specialist who spends two hours and proves the plumbing is sound has done the job you paid for.

Frequently Asked Questions
How do I know if I have a hidden water leak?
Close all taps and check the water meter. Movement with everything off means water is escaping on your side.
Warm patches on a floor, a jump in the municipal account with no change in usage, or damp that does not dry out are the other common signs.
Does leak detection involve breaking anything?
No. Detection is non-invasive. Acoustic, thermal and pressure equipment locates the leak through the surface so only the marked spot is opened for the repair.
How long does it take?
A straightforward domestic leak is usually located within one to two hours. Underground lines under paving or long garden runs take longer.
Is detection covered by insurance?
Many household policies cover detection and repair of a sudden burst, but not gradual wear. Check whether your policy requires the insurer to appoint the contractor before you book.
