Water & Flood Damage Restoration in Hang Hau

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 Hang Hau, 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.

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.

It scales with the water category and the area affected. A single-room clean-water dry-out is a low four-figure job; grey-water across multiple rooms costs several times that; a sewage (black-water) or major flood restoration runs well into five figures. The clean-up is often only stage one before repairs.

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.
