Why call DrainFix HK for Sai Ying Pun kitchen drain unblocking
- Sai Ying Pun-specific knowledge. Sai Ying Pun mixes pre-war tong lau, post-war walk-ups, and modern HKU-area towers. Pre-war buildings have rare brick-mortar drain construction that needs careful clearing. We don't damage heritage features — chemical clearing where needed, mechanical only where safe.
- Service-specific method. HK kitchen blocks are 95% grease + food debris. Restaurant kitchens far worse than residential. We use hot-water + manual auger; commercial cases need grease trap pumping. Always test with running water after.
- Fixed price quoted on phone. No 'we'll see when we get there' surprises. From HKD 400 (basic) / HKD 500-650 (with grease trap).
- 7-day re-block guarantee. Same drain re-blocks within 7 days, we return free.
- Receipt + tax invoice always. For tenant-landlord reimbursement or building AP.
