Why Secure French Doors


When first considering a French door for your home, you may only think about its appealing look and the amazing amount of light it lets into your room. Sadly, most burglars also find these features tempting.

As there is a lot of glass on a French door, people can do a smash-and-grab to get some quick money. Double French doors always include a middle seam that can be opened easily as well. That is why you need to secure this type of door.

The good news is you can install this beautiful door for your house and still have enough safety. In our opinion, there is no better option than securing the French door, especially with its flimsy door frame and many windows around this glass entry.

Be aware that even inexperienced burglars like to target such doors. Most people think that a French door is often on the side or back of their home, so it is not necessary to have much protection.

Little do you know, burglars will aim for these spots when considering forced entry if they know your house has French doors.

In the spot where the double doors meet, you will find very little support. Thus, even a simple center kick can make this French door pushed open, not to mention all the fragile glass panes.

What You Will Need to Follow This Tutorial


Now that you have been fully aware of how risky an original French door can be for your home, this is a quick overview of things you can improve to protect your property from unwanted thieves targeting this type of standard door.

How to Secure Your French Doors

The first thing you need to remember when installing a French door is definitely ensuring safety and protection for the indoors. The following French door security devices will make your beautiful entry as impenetrable as possible.

Glass Panes


Since most French doors include a large number of glass panels, it causes this entry to become more vulnerable. But it is almost impossible for a burglar to squeeze himself through a broken glass pane’s tiny gap.

In most cases, burglars will crack a single glass pane, reach inside using their hands to open the French door, and get in the house. You need to strengthen its main weakness, specifically how it divides two doors.

Tips: Hurricane-rated glass, impact resistant glass, or laminated glass would be the perfect option to equip your new French door due to its incredible toughness that is hard to break. You should consider this material for your new doors if you live in hurricane prone areas.

In addition, a plain glass French door has another issue of exposing your indoors. That way, burglars can easily check out whether anyone is home. Other front door types are often colored, distorted, or frosted to prevent this problem. For privacy when using French doors, you can use curtains or blinds.

Lock and Hinges


Although it seems obvious, a lot of people do not replace the unreliable and insufficient set of door locks and hinges that comes readily with a French door. (Find out more top-rated locks for french doors here)

In terms of the hinge screws on a French door, make sure they have a minimum length of 3 inches. Also, the deadbolts should have at least a 1-inch throw.

Note: Often, mortise locks are more powerful than non-mortise locks.

For your information, a locking system with 3 points will be the finest security for a French door. If your door comes in a pair, it is ideal to secure one of them for good since burglars will have a harder time forcing this passive door open.

Security Bar


This measure of installing French door security bars is simple but optimal. It helps prevent any potential burglar from attempting to kick your door and get inside. Moreover, there are even security bar options with alarms for better security.

Door Materials

As mentioned earlier, there is some helpful advice about the door material in case you have not bought a new French door yet. Thick doors made from wood are the best. The thicker doors will definitely be better at adding protection.

Of course, you should not miss out on hurricane-rated glass when it comes to door thickness. Getting a sturdy steel frame would also be an excellent security layer to reinforce your French door to reach a higher, safer protection level.
