Is this your problem?
- Pressure dropping with no visible leak
- Stain on the ceiling below a bathroom
- Tile-buried socket weeping
- Crack found only after opening the wall
Concealed work is a different trade from open-pipe repair. Sockets buried in tile or concrete decay unseen; by the time pressure drops or the neighbour's ceiling stains, the joint inside the wall is already cracked. We open at the marked point — or at the most probable point when tracing can't resolve it — repair the failed section, test the line under pressure, and close the access.
What makes this rate 6,500 and not 3,500: tile-safe cutting, working blind in a wet cavity, matching old thick-wall pipe and fittings that aren't in catalogues anymore, and finishing the opening cleanly. In Colombo 07-style homes where the whole system runs under tile or in walls and nobody holds a plan, diagnosis time is part of the job — we price that in instead of surprising you with it after.
"You have to break the whole wall to find a leak."
Modern tracing tools mark the point within centimetres — one small opening, not a demolition.
A concealed leak in a wall cavity can rot timber framing for months before the paint bubbles — early tracing saves the structure.
Cause
Hidden leaks live inside walls and under slabs, causing damage you can't see until it's catastrophic.
How We Fix It
Thermal/acoustic trace, mark the point, minimal access cut, repair, pressure test, patch.
If you hear water running when everything is off, you likely have a concealed leak. Call us before the damage spreads.
A concealed leak destroys walls, floors, and foundations from the inside. The longer you wait, the more it costs.
A concealed leak runs downhill of the pipe, so the damp patch is never directly under the break — we work back up the fall of the line, not down to the stain.
What to Do Before We Arrive
- Note exactly where you hear running water or feel damp — even at night — the sound guides our first probe.
- With every tap closed, watch the water meter — a moving dial confirms a hidden leak before we open anything.
- Move furniture away from the suspect wall — we work with listening gear and small, planned openings.
- Do not seal or paint over the damp — surface fixes hide the evidence we need to find the source.
