Why call DrainFix HK for Sha Tin outdoor / light-well drain

- 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.
