Common in Mong Kok
high-density older flats with shared exterior condensate drip-lines — drips on lower-floor neighbours when clogged.
Pre-call checks
1. Turn off AC immediately if you see ceiling stain spreading — stops further damage.
2. Photograph the stain pattern + timestamp — useful for diagnosis + insurance.
3. Check if downstairs neighbour also reports drips — if yes, building-side manifold issue (different scope).
What we do on a Mong Kok call
Source-locate first
We identify whether the blockage is in your in-flat drip line, the wall-cavity routing, or the shared manifold. Different fixes. Different costs. Diagnosis prevents charging for the wrong work.
