How we clear it
Why DrainFix HK for Tin Shui Wai outdoor drain clearing
- Tin Shui Wai-specific knowledge. Mix of large public-housing estates (Housing Authority responsibility for shared stacks) and Kingswood Villas private (Sun Hung Kai management); ground-floor units occasionally have flooding from podium drains during black rain.
- Service-specific method. We do not over-tool. Residential cases use residential equipment. Industrial high-pressure jet is reserved for genuinely necessary cases (severe scale, restaurant grease trap) and quoted separately on-site.
- Starting price quoted in writing on WhatsApp. No "we'll see when we arrive" surprises. From HKD 800. Complex cases (shared stack, restricted access, old cast iron) quoted on-site with your written approval before any work.
- On-site re-test before we leave. We run water / flush / spin cycle for 60 seconds to confirm clear flow. If it does not test clear, we keep working — no "looks fine, we're off" departures.
- Receipt + tax invoice always. For tenant-landlord reimbursement, OC reimbursement, or company expense claim. WhatsApp PDF on request.
