Why Choa Chu Kang sees this kind of mould
Choa Chu Kang is a western mature town with 1990s HDB blocks and newer BTOs at Keat Hong and Brickland. Its proximity to the Western Catchment, Bukit Batok Town Park and nature reserves exposes blocks to elevated forest-edge humidity, while the older housing stock carries original bathroom waterproofing and concealed aircon trunking prone to condensation.
