Vulnerable Windows & Doors

Door security

If your front and back doors are not secure, neither is your home. Two thirds of burglars gain entry through a door. Remember, quality locks and bolts are only as strong as the door and the frame to which they are fitted. Glass panels on or around doors are especially vulnerable, so it’s worth replacing them with laminated glass. Adding the Home Secure Sash Jammer, can really help prevent a break in. This is the most sold sash jammer in the UK today.

Door viewer

If you don’t have a window in the door or some other way of checking who is calling, fit a door viewer. Look through this to identify callers before you open the door. The Home Secure viewer, is available in a chrome finish, or a brass finish.

Door chains

These allow the door to be opened a short distance to allow checking of identification. They can stop callers pushing their way in, but must be securely fixed to avoid screws being pulled out. They do not contribute to the security of a locked door against burglary. This can be an added safety aspect to any property; it will deter an intruder if they notice the ‘victim’ is using a door chain.


Never hang a spare key inside the letterbox. This is an obvious place that a thief will check. Letterboxes should be at least 400mm (16 inches) from any locks. Consider fitting a letterbox cage or other restrictor, which prevents thieves from putting their hands or gadgets through the letterbox and trying the latches from the inside.

Multi-point locking

Multi-point locking involves several hooks or bolts holding the door into the frame. The lock cylinders should be tested to BS EN 1303 Grade 3 and can be replaced. If your door is BS: PAS24 and it requires replacement locks ensure they are changed like for like to continue the level of security.

Window Security

Windows are a popular point of entry for burglars through breaking glass or just being left open.

If you are replacing windows, take the opportunity to install windows certified to British Standard BS7950 ‘Windows of Enhanced Security’ and consider using laminated glass in ground-floor and accessible windows such as those above a flat roof.

Ground floor opening windows and easy to reach windows, such as above a flat roof or near a drainpipe, should have locks unless used as a fire escape in which case laminated glass still provides security. Even small windows such as skylights or bathroom fanlights need locks. If a thief can get their head through, with a bit of effort the body can follow.


In the hot weather, it is important to add ventilation to a home, but not reduce the level of safety or security. Adding the some of the Home Secure window restrictors can act as a deterrent and add piece of mind, if the home is occupied by children.

Downstairs windows can be left open whilst the occupier is upstairs, safe in the knowledge that the home is safe.
