    Draughty windows are a common occurrence in many home. The main cause of draughty windows is faulty hinges; the rubber seal can also perish and allow draughts to get in.

    Window hinges are a very important part of your window hardware. Well fitted hinge are designed to run smoothly along the track to open out and ventilate room and close to seal the window against the frame. To get the best from your hinges special care must be given to cleaning and lubrication. When your window hinges have failed or are strained you will notice an increase in noise from out side, draughts, and dirt around the frame and on blinds. In winter the effect is more obvious the cold air from outside mixes with the warm air inside and causes moisture on window and window frame. When this happens with older aluminium window frames mould can form where frame meet wall, this is particularly common in bedrooms.

    The end cap of the hinge can stretch and doesn’t close in tight and the resistance block can break causing the hinge to kick out at the bottom are the main areas where the hinge breaks down. The hinges are not guiding the window along the track to give a tight seal all around the frame. A coin could easily fit between hinge and seal at this stage hinges will need to be replaced.
