"We were losing nearly an inch a day and had no idea why. They traced it to a cracked return line under the paving without digging up the whole patio. Fixed it the same week and the level has held perfectly since."

Pool Leak Detection in Johannesburg, Find & Fix Pool Leaks
If your pool keeps dropping and you're forever topping it up, we'll find out exactly where the water is going, and fix it. Non-destructive leak detection across Sandton, Randburg, Midrand, Roodepoort and greater Johannesburg.
Stop the water loss
Find the leak before it costs you more
A leaking pool wastes water, runs up your municipal bill and can quietly undermine the paving and structure around it. The tricky part is that most leaks hide underground or inside the plumbing, where you'll never spot them by eye. Our pool leak detection service pinpoints the exact source so nothing gets dug up on a guess.
Using pressure testing, dye testing and electronic listening gear, we trace the leak to the centimetre, whether it's a cracked shell, a failed fitting or a split pipe under the deck. Looking for trustworthy swimming pool leak detection near me in Gauteng? We find it, then we fix it. We cover homes right across the region, from Sandton through to Midrand.
- No-dig location, we find the leak before any digging starts.
- Structural & plumbing leaks, shell cracks, fittings and underground pipes.
- Detect and repair, one team finds the leak and fixes it properly.
- Clear inspection fee, you know the cost before we book the visit.
Plumbing leak or structural leak?
The fix is very different depending on where the water escapes. Plumbing leaks happen in the suction and return lines buried under the paving, often where pipes join the skimmer, pump or returns. Structural leaks come from cracks in the shell, splits at the steps or worn light and inlet fittings inside the pool.
We confirm which type you're dealing with before quoting any work, so you're not paying to chase the wrong thing. Once located, we handle the fix, and for bigger structural work we can roll it into our wider pool repairs service. If the trouble turns out to be a failing pump or pipework at the equipment pad rather than the shell, our pump and equipment repair team sorts it out on the same visit.
Topping up every couple of days? That's not normal evaporation. Catching a leak early limits the water you waste and stops the surrounding paving from sinking, book an inspection before it spreads.
The warning signs to watch for
- Rapid water loss, the level drops a centimetre or more a day, faster than normal.
- Constant topping up, you're refilling the pool every few days to keep it swimmable.
- Damp or sinking paving, soggy patches, lifting tiles or paving settling near the pool.
- Air in the returns, bubbles spitting from the jets point to a leak on the suction side.
- Climbing water bills, an unexplained jump in municipal water charges.
- Cracks or wet walls, visible cracks in the shell or persistent damp in nearby walls.

How we track down your leak
Confirm it's a leak
We run a bucket test and rule out evaporation, so we only investigate genuine water loss.
Isolate the source
Pressure testing the lines and dye testing the shell separates plumbing leaks from structural ones.
Pinpoint the spot
Electronic listening equipment locates the exact point the water is escaping underground.
Repair and verify
We fix the leak, then retest the pool to confirm the water level is holding before we leave.
Pool leak questions, answered
How do I tell if my pool is leaking?
The clearest signs are a water level dropping faster than usual, topping up far more often, damp or sinking paving, cracks in the surround, air bubbling from the return jets and a climbing water bill. If you're refilling every few days, it's worth a leak inspection.
How much water loss is normal versus a leak?
In the Gauteng summer, evaporation can take a few millimetres a day off an exposed pool, which is normal. Losing a centimetre or more per day, or much more than nearby pools, usually points to a leak. A simple bucket test separates evaporation from a real leak, and we can confirm it for you.
How does pool leak detection work?
We combine several methods. Pressure testing isolates and pressurises the plumbing lines to find breaks, dye testing reveals draw at cracks and fittings in the shell, and electronic listening equipment pinpoints the exact spot where water is escaping underground. Together they locate the leak precisely before any repair.
Can you find a leak without breaking up the paving?
Yes. Our approach is non-destructive, no-dig location. We pinpoint the leak first using pressure, dye and electronic equipment, so any excavation or repair is limited to the exact spot rather than tearing up your whole pool surround on a guess.
How much does pool leak detection cost in Johannesburg?
Leak detection is charged as a set inspection fee that covers locating the leak. The repair is quoted separately once we know whether it's a plumbing line, a fitting or a crack in the structure. We give you the full picture and cost before any repair work begins.
Which areas do you cover for leak detection?
We carry out pool leak detection and repair across Johannesburg, Sandton, Randburg, Midrand and Roodepoort, plus surrounding suburbs and the greater Gauteng region. See all service areas.
