Water & Flood Damage Restoration in Mei Foo Sun Chuen

Category 1 is clean water from a supply line; Category 2 (grey water) contains contaminants like from a washing machine or dishwasher; Category 3 (black water) is sewage or flood water and is a health hazard. The higher the category, the more removal, disinfection and cost involved.

Immediately. Mould can begin within 24-48 hours and standing water keeps wicking into walls and floors. Professional restorers extract, then run air movers and dehumidifiers for days — the faster drying starts, the less material has to be replaced.

Sudden, accidental damage (a burst pipe) is usually covered; gradual leaks, neglect and in many policies flooding from outside are not. Document everything, mitigate promptly (insurers expect it), and confirm whether flood cover is a separate policy.

Surface water is the visible part; moisture wicks into drywall, subfloor, insulation and framing where you can't see it. Professionals use moisture meters to confirm materials are dry to spec — skipping structural drying is how you get mould and warped floors weeks later.

Ask whether they follow the IICRC S500 standard, whether they do 24/7 emergency response, how they document moisture readings, whether they bill your insurer directly, and what happens if hidden damage is found mid-job.

Mitigation (extraction and drying) and reconstruction (replacing drywall, flooring, painting) are usually separate phases and sometimes separate contracts. Clarify up front whether your quote covers the rebuild or just the dry-out.

In Mei Foo Sun Chuen, prioritise firms with 24/7 emergency response, recognised certification, insurance-billing experience and documented moisture logs. In a flood event demand surges, so a company that answers fast and scopes properly is worth more than the cheapest quote.

Single-room dry-outs typically run HKD 3,000-16,000, multi-room jobs HKD 16,000-70,000, and major water events HKD 70,000-280,000 with reinstatement.
