Windows and Doors in an HDB Flat

Window replacement is a separately regulated trade

Installing or replacing HDB windows must be carried out by a window contractor approved for that work, which is a separate approval from general renovation contractor registration (HDB). A renovation quotation that includes windows should name who is doing that portion. TO FILL: window replacement by opening size and type

Main door, fire rating and the frame

Replacing a main door usually means dealing with the existing frame, and in HDB flats the door assembly is bound by requirements the leaf alone does not satisfy. The frame condition determines whether this is a leaf swap or a frame-and-leaf job.

Sliding doors inside the flat

Internal sliding and folding doors buy floor area back from door swings, at the cost of acoustic separation and, for top-hung tracks, a structural fixing that must be planned with the ceiling.

Grilles and safety

Window grilles and their fixing are a safety item rather than a decorative one, and the fixing substrate matters more than the pattern.
