Demolition Services in Kowloon

For any building built before asbestos bans (broadly pre-2000), yes — a survey and, if found, licensed removal must happen before demolition. Disturbing asbestos is a serious health hazard and is tightly regulated; a contractor who ignores this is a major red flag.

Gas, electricity and water must be professionally disconnected (capped) by the utility or a licensed trade before demolition begins — not just switched off. This is a safety-critical step; a reputable demolition contractor coordinates it and won't start until it's confirmed.

A room strip-out is often a day or two; a full house gut a few days to a week; a full structural demolition one to two weeks including site clearance. Asbestos removal, permits and utility disconnections add lead time before work can even start.

It scales with what's being removed: an interior strip-out of a single room is the cheap end; a full internal gut of a home is mid-range; a complete structural demolition of a building is the big job. Debris volume, disposal fees, access for machinery, and any hazardous materials drive the price more than floor area alone.

For anything structural — removing walls, demolishing a building or a large extension — yes, almost always (see country notes). Interior soft-strip of non-structural elements often doesn't, but check locally. Utilities must be safely disconnected first, and neighbours may need notifying.

A room strip runs about HK$5,000-28,000; a full flat strip HK$20,000-100,000; larger commercial jobs much more. High-rise debris removal, lift access limits and noise-hour restrictions add to the cost.
