How to secure French doors from burglars

Grey coloured timber french doors
French doors are highly sought after by homeowners who love their elegant styling, large portions of glazing and ability to ventilate homes. Sadly however, they’ve found themselves targeted by burglars from time to time. But don’t threat just yet, because there are ways you can secure them, which we’ve looked into for this blog.

Using a reputable installer

This should be your first point of call for ensuring security. A poor installation is likely to result in French doors which are inadequate in a number of areas, security being one of them.


The glass area on French doors is a large security risk. Usually, burglars tend to break one of the glass panels, creating enough space for them to put their hand inside and unlock the doors. Making sure toughened glass is fitted will make breaking any glass panels significantly more difficult. Lifestyle Windows fits toughened glass in our French doors as standard.

Cylinder locks

A common method of entry is via a technique known as lock snapping. This is where the cylinder is broken before the lock is manipulated to open. This problem is quite common with doors that have been fitted with inadequate euro cylinder locks. Ensuring anti-snap lock cylinders have been fitted is a way of preventing yourself from falling victim to this method of entry.


Hinges which are not properly secured to the frame are able to be removed. However, if security hinges are fitted, removing them will be far more difficult. If they haven’t been fitted, you can fit your hinges with screws which are at least 3 inches long.

Multi-point locking system

Making sure multi-point locks have been fitted is an important method for increasing security. Without them, the doors aren’t secured at multiple points around the frame and can easily be manipulated open with enough force. We ensure to fit multi-point locking systems on all of our French doors, so they’re not susceptible to this issue.
