Proper Maintenance Of Windows

The windows in your home can deteriorate over time due to wear and tear. If not maintained properly, they can fall off posing a serious hazard to persons below such buildings. It is therefore important that windows are checked regularly, and repaired where necessary, to ensure they remain safe and secure.

Under the law, there are certain liabilities imposed on property owners and Management Corporations to maintain their private or common property, including windows, so that they do not pose a danger to other users.


  • Check rivets and screws and if they are made of aluminium, they should be replaced with stainless steel ones.
  • Clean and remove dirt from the joints/moveable parts such as the hinges, sliding shoes, and track, at least twice a year.
  • Lubricate or grease these areas, as well as the pivoting points at least once every 6 months.
  • Check the action of the windows, clear the stiffness by applying light oil or spray lubricant to the joints/moveable parts and then open and close the windows several times.
  • Check the glass panes for cracks or loose panes.
  • If any part of the window (e.g. rivets, screws, safety catch, roller, rubber gasket that holds the glass pane) is loose/corroded/missing, you should engage an approved window contractor to repair the window. The repair work should ensure that:
    • The moveable parts are properly and securely attached to the fixed frame of the window.
    • All loose screws are tightened.
