Drain Unblocking Cost Reference
(Prices may be higher for premium-tier cases)

For sudden complete blockages, try a manual plunger first before calling a professional. Avoid heavy chemical drain cleaners — frequent use corrodes aging PVC pipes, potentially causing leaks that cost far more to fix.
Frequently Asked Questions
Kitchen drains are most commonly blocked by grease buildup; bathroom and toilet blockages typically involve hair, wet wipes, or foreign objects. Building main drain blockages may result from accumulated discharge from multiple units and require coordination with building management.
Maintain kitchen and bathroom drains every six months using drain cleaner or natural enzyme cleaners. Avoid flushing grease, food scraps, or wet wipes. Units with grease traps should clean them regularly to prevent grease accumulation in the main drain.
Common building drains are common areas — repair costs are borne by the Owners' Corporation and apportioned among owners. If a blockage clearly originates from a specific unit (e.g. large debris dumping), costs can be recovered from that owner. Branch drains within private units are the owner's responsibility.
Emergency or after-hours drain unblocking in Hong Kong (after 10pm or on holidays) typically carries a surcharge of HK$500–$1,500, depending on the contractor. Always confirm whether the quote includes any emergency surcharge.
