If you’ve just searched “how to secure sash windows” you might be questioning their overall security all together or perhaps you simply want to ensure your sash windows are as secure as they can be to keep your loved ones and your belongings safe.
Sash windows feature two sashes that slide up and down inside a frame and are the most popular types of window in the United Kingdom. These windows can provide as much security as other types of windows. It will always depend on how well-maintained they are and if they are properly locked. However, there are a few other ways to increase their security, keep on reading to find out more.
- Keep your sash windows well-maintained
Keeping your sash windows in a good condition is a given. Any entry point to your home which has clear signs of wear and tear will be more subject to damage and will offer reduced security. When you notice that your sash windows are not working properly or are showing their age, maybe it’s time to replace them.
- Sash window fasteners
There are available a few options of sash window fasteners to safely secure your sash windows, including standard sash fasteners, Fitch fasteners and Brighton fasteners.
Standard sash fasteners, such as From the Anvil black standard sash fasteners, are installed on the mid-point of your sash windows and hook the top and bottom sashes together.
Fitch fasteners are also a traditional style of sash fasteners which feature a simple rotating action for easy opening and closing. These are available as non-locking versions, including the polished brass fitch sash fasteners and locking versions, such as the polished chrome locking fitch sash fasteners.

Brighton fasteners, such as our polished chrome brighton sash window fasteners, are used to both fasten and lock sash windows. They are designed to fit the centre of sash windows and feature a screw tight function to either fully lock the window when closed or to fasten the lower sash window when it is a little bit open to allow for ventilation.
- Sash window stops

Sash window stops, such as our 19mm roller sash stops, can also be referred to as security restrictors. These are installed in pairs to the stiles of the top sash in order to prevent the two sashes from sliding past each other. Thus, they prevent anyone from opening the sash window enough to be able to climb through.
- Window restrictors

Window restrictors are an important element to further improve your sash window security. Jackloc sash window restrictors are perfect for any type of window and are designed to also reduce the risk of falls from windows by limiting the distance your sash windows are able to open.
- Close your curtains
Closing your curtains at night or while you are away on holiday is quite a helpful crime prevention method as it stops people from looking into your home and seeing any valuables you might have. Also, always remember to fully close and lock the windows when you go out, whether you are going on a short walk to the grocery store or for a week-long holiday in Spain.
