Listen
Acoustic microphone walks the suspected wall and floor. Quietest house on the block for ninety seconds.
What a typical trace looks like
You see a damp patch, hear a faint drip behind a wall, or notice your water bill climbing. We arrive with three tools — an acoustic ground microphone, an infrared camera, and a low-pressure nitrogen test rig — and isolate the leak before deciding where to cut.
- Acoustic listening through tiles, walls and slabs
- Thermal imaging to find hot-water line escapes
- Pressure-decay nitrogen testing on isolated circuits
- Borescope inspection inside cavity walls before we cut
What we repair
From hairline copper pinholes to cracked PE-X manifolds.
Most of KL's older condos use copper for hot water and PVC for cold. Newer builds increasingly run PE-X composite. We carry consumables for all three.
- Copper pinhole repair & section replacement
- PVC cold-water line patching
- PE-X push-fit and crimp joint redos
- Brass compression fitting replacement
- Inlet stop-tap and angle-valve renewal
- Galvanised steel section cut-out & couple
- Shower mixer cartridge replacement
- Sink and basin trap reseat
How a leak job runs
Four hours on a small one. Half a day on a stubborn one.
If we cannot find it inside the scoping visit, we say so plainly and bring the heavier kit back on a return run.
Look
Thermal camera over warm-water runs, borescope into wall cavities, tile pattern survey.
Test
Nitrogen pressure decay on isolated branches confirms the section.
Repair
Smallest possible opening, like-for-like material, tested twice before we close it back up.
Common questions
Most-asked, for this service.
Will I need to retile the whole bathroom?
Almost never. We aim for a single tile lift, sometimes two, mapped using acoustic and thermal cues. Where retiling is genuinely needed we discuss it before we drill.
How long does a typical leak detection visit take?
Plan on 90 minutes for the scoping visit. Some leaks reveal themselves in twenty; the ones hiding behind cavity walls take longer.
Do you do landlord reports for insurance claims?
Yes — photos, thermal images, pressure-test logs, and a one-page summary on letterhead are included as standard for insurer-claimable jobs.
What if the leak is in the slab between floors?
We can usually isolate the run and reroute via the ceiling void of the unit below, with the neighbour's consent. Pulling up tiled flooring is the absolute last option.
Suspect a slow leak? Don't wait for the ceiling stain to spread.
WhatsApp us a photo of the wet patch and the suspected room — we'll tell you whether to call us, an electrician, or your building manager first.
