Window Crime Prevention Advice


A third of burglars get in through a window. If you are replacing windows, take the opportunity to install new ones that use laminated glass, particularly in accessible windows and ground-floors as this is much harder to break. Install windows that have locks that can easily be seen from the outside which will put thieves off. They don’t want to have to break the glass to get to the lock and risk attracting attention. Even if they break the break they would still not want to risk cutting themselves climbing through broken glass.
Fit window locks with keys to all downstairs windows and those that are easily reached, for example, windows above a flat rook or near a drainpipe. Home security and DIY shops sell inexpensive, key-operated locks to fit most kinds of windows. You may need more than one window lock, depending on the size of the opening you need to secure.
Don’t leave out small windows such as bathroom fanlights or skylights as a thief can get through any gap that is just larger than a human head. Louvre windows are especially vulnerable as thieves can easily take the slats out of the frame. Glue the slats into place, and fit a special louvre lock, or better still, replace them with fixed glass.
Remember to remove the keys for the windows and keep them out of sight in a safe place. And remember to keep windows locked when you are not in your house.
Consider fitting security grilles or security bars to vulnerable windows - but only if these windows are not escape routes in case of fire. Many DIY shops now sell decorative wrought-iron grilles. Consider casement locks as these make it harder to open windows without the correct key.
Although fanlight locks have a metal bolt to secure the metal arm used to open and close the window, you should not rely on these locks and consider fitting a casement lock too.
