Water & Flood Damage Restoration in Wong Tai Sin

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.

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.

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.

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.

In Wong Tai Sin, small dry-outs sit at the low end of the national range while major flood restoration with structural drying and rebuild runs into five figures, driven by water category, area and how long the water sat.

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.
