Why call DrainFix HK for Kwun Tong outdoor / light-well drain
- Kwun Tong-specific knowledge. Kwun Tong industrial-converted-residential buildings have unusual drain configurations — original commercial-spec pipes never designed for residential volume. We see weekly calls for blocks in converted 1970s industrial-now-residential buildings around Hung To Road / How Ming Street.
- 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.

- 7-day re-block guarantee. Same drain re-blocks within 7 days, we return free.
