HDB-licensed window contractors

Windows in a high-rise flat are a safety matter, because a window that falls can kill. HDB keeps its own list of contractors approved to install and replace windows in its flats, separate from its renovation directory, and every firm on this page comes from that list. Each row shows the licence number that backs it, so you can match it against the name on your quotation.

Many renovation contractors subcontract windows, so the firm on your quotation may not be the firm that installs them. That is normal, but ask which listed window contractor will do the work and find that name here. A firm on this page but not on HDB’s renovation directory is licensed for windows only; for anything else in an HDB flat, you also need a firm from the renovation list.

Ask about the frame and the fixings, not just the glass. Rivets, brackets and the aluminium frame are where windows fail, and as the owner you are responsible for maintaining them once they are in, so check them every year. The table is sorted by registered name. Use the filter to show only firms that are also on HDB’s renovation directory.
