What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Hong Kong typically run above the national range; smaller towns below it.

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
How fast do I need to act after water damage?
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.
Does restoration include repairs or just drying?
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.
Will insurance cover water damage restoration?
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.
How much does water damage restoration cost?
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.
Is drying really necessary or can I just mop up?
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.
What are the three water damage categories?
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.
What questions should I ask a restoration company?
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.
What does water damage restoration cost in Hong Kong?
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.
