How we find the real source.
We don't guess. We diagnose the source, then fix it — so it stays fixed. Most leaks that "come back" were never properly traced in the first place.
Moisture mapping
Calibrated meters trace the wet path from the stain back to the true entry point.
Thermal imaging
Infrared cameras reveal hidden damp behind walls, ceilings and slabs.
Water ponding test
Controlled ponding on floors and terraces confirms exactly where water enters.
Dye & pressure tests
Coloured dye and pipe pressure tests isolate plumbing vs waterproofing failures.
"Why do leaks come back? Because the surface got patched, but the source was never found. We reverse that order."
Leak from the unit above? Or into the one below?
Inter-floor leaks are one of the most common — and most stressful — situations in Singapore. Who's responsible? Who pays? Where's it actually coming from?
We identify the true source, document it properly with reports and photos, handle the repair, and give you clear guidance on the HDB, town council or MCST process.
- → Independent leak-source diagnosis report
- → Neighbour & town council communication support
- → Repair with written warranty
Two situations. One clear process.
We handle the whole messy process — inspection, source report, repair, and the paperwork for HDB, town council, MCST or your neighbour. You just need to make one call.
Water dripping into your ceiling?
- 1. Free inspection at your unit. We assess the stain pattern and rule out plumbing above your ceiling first.
- 2. Independent source report. Documented findings pointing to the responsible party — usable with HDB / town council / MCST.
- 3. Neighbour coordination. We can meet the upstairs owner with you and explain the fix professionally.
- 4. Repair once source is fixed. We restore your ceiling and issue a written warranty.
Neighbour says it's coming from you?
- 1. Diagnose before you accept liability. Not every downstairs leak is your fault — we prove where it actually originates.
- 2. Test bathroom, balcony, pipes. Ponding, moisture and pressure tests isolate the true source in your unit.
- 3. Fix the cause, not the ceiling below. Proper membrane, joint or plumbing repair at source — one job, one warranty.
- 4. Documentation for the neighbour. Photos, scope and warranty certificate — so the case closes cleanly.
