Why call DrainFix HK for Causeway Bay outdoor / light-well drain
- Causeway Bay-specific knowledge. Causeway Bay residential stock is dominated by 1960s-1980s towers — typical 30-50 m² flats. Times Square / Hennessy Centre area + Tin Hau MTR catchment are most frequent. CWB lifts (1.4×1.2m typical) make commercial-grade equipment delivery awkward.
- Service-specific method. HK outdoor / light-well / balcony drains block from leaves, mud, dust + AC condensate residue. Critical to clear before rainy season — backflow during heavy rain damages walls + electricals. 1-2 hour job depending on access.
- Fixed price quoted on phone. No 'we'll see when we get there' surprises. From HKD 600.
- 7-day re-block guarantee. Same drain re-blocks within 7 days, we return free.
