Hidden Shower Leak in Kepong: Tracing and Fixing a Concealed Pipe

A homeowner in Kepong called us about a damp patch that kept coming back on the shower wall. The tiles looked fine, but the wall stayed wet and the water bill had crept up — the classic sign of a concealed pipe leak hidden inside the wall.

A leak you cannot see is still a leak

Concealed pipes run inside walls and floor slabs. When one starts weeping at a joint, the water has nowhere to go but into the plaster, the tile bed, and eventually the next room. By the time you see a stain, the leak has usually been running for weeks.

We started with concealed leak detection (RM200–600) — isolating the line, pressure-testing, and pinpointing exactly where the pipe had failed, so we only had to open the wall in one place.

Replace the pipe, not just patch the joint

Once the bad section was exposed, we cut out the failed pipe and ran a new line in modern PPR piping — heat-fused joints that do not corrode the way the old fittings did. We pressure-tested again before closing anything up, so we knew the wall was going back over a dry, sound pipe.

Then it was re-tiling, re-grouting, and reinstalling the shower mixer and rail set.

What this kind of job costs

• Call-out & inspection: RM100–150
• Concealed leak detection (wall/slab): RM200–600
• Exposed pipe leak repair: RM100–380
• Re-tiling and finishing depend on the area opened up — we quote it before starting

Catching it early matters: a concealed leak left alone soaks into the slab and can reach your downstairs ceiling or your neighbour's unit, turning a one-wall repair into a much bigger bill.

Damp wall that will not dry out?

If you have a stain that keeps coming back, a spike in your water bill, or the sound of running water with every tap closed, send us a photo on WhatsApp. We will tell you whether it is a simple surface fix or a concealed leak — and what it should cost in Kepong before we come out.
