How To Secure French Doors

How To Secure French Doors

When homeowners think of French doors, they first visualize them as a stunning and desirable addition to their homes. But can those beautiful french doors be a security concern as well?


Aside from looking nice and being a beautiful entry to a patio or deck area, they also let in lots of light. How pleasing to the eye does that sound, right? 

Unfortunately, intruders find them just as appealing. Why? Because French doors are one of most vulnerable door types to break-ins. Even inexperienced burglars know that a house with French doors is likely to allow them quick and easy access into the property.

What Makes French Doors Difficult to Secure?

French doors are also referred to as double doors. They’re doors that meet in the middle with one regarded as the passive door which is seldom used. The other door is referred to as the active door which is the door that opens and closes.


Several parts of a French door make it hard to ensure complete home security. Here are the aspects that make French doors weak security points:


  • The doors open outward which means the hinges are always on the outside of the door, exposed to the elements. Since the hinges are on the outside, a home intruder can easily remove the pin and take the door off the hinges.


  • Because French doors have large glass areas, they leave no place to put locks out of reach of mischievous hands. No matter where the lock is, a burglar can break or cut the glass and reach inside to unlock the door.


  • The glass panes are also weak spots in the door and are easy to remove or break.


  • Double French doors are vulnerable where the two doors come together in the middle. There is generally only an overlap of molding where the doors meet. If the doors open into the room, this weak spot makes them extremely easy to kick in.


  • The doors also don’t have a good place to put hardy locks. Since the windows can be broken and the doors can be broken in, it’s hard to find a place to lock the doors.


Luckily, you can still have these beautiful doors in your home and be secure. That’s why this article is dedicated to offering some help in securing your home if you’re considering installing French doors, or if you already have them so you can feel even safer.


Here are a few tips on how to secure a French door from burglars:

How To Secure French Doors: Keep Your French Doors Locked

Locking your French doors is such a simple, obvious step, and getting into the habit of always locking all your doors when leaving the house might make all the difference.


That may seem like a no-brainer, but that’s something that people may not think of doing when the doors are in the back of the house.


This may come as a surprise to some, but almost half of all home break-ins are not committed forcibly. This means that the thief was able to parade, undeterred, unto the property by simply opening the door.


By doing so when you leave your house, you may deter potential burglars because they may not be prepared to use force.

How To Secure French Doors: Apply Glass Film on Glass Panes

When you add a security film to your doors, this adds another layer between you and the outside world. French doors are made with lots of glass panes, which makes it easy for burglars to smash these if they want to get into your home. One way to secure these glass panels is to coat them with a security window film.


A glass security film is made of polyester materials. It works just like your car’s windshield glass - it holds glass together and keeps it from shattering upon impact. Not only will these films keep your place safe from bad people, but they also work fine for strong winds, too.

How To Secure French Doors: Invest in Impact-Resistant Glass

It is often the glass panels that concern homeowners most about their French doors. They’re so easy to break, right? Wrong. If you are considering French doors, it is good to think about investing in good hurricane-resistant impact doors that are layered with tough glass that has the power to take great impacts and kicks and still not break. 


This glass is not to be confused with tempered-glass windows and doors, as tempered glass is strong, yet still easy to shatter.

How To Secure French Doors: Bolt It

There are several factors to consider when choosing a lock for your French doors: it should be difficult to break, and it should strengthen that weak point between the two doors.


French doors have a particular vulnerability when it comes to home security, and this is because they are composed of two glass panels with a divide between them that creates a weak point. 


This susceptibility to being broken into is what makes criminals target this particular design of door more often, and this means you need to strengthen this particular area. 


You’re going to want to use a deadbolt and a device called a mortise lock. These mechanisms are embedded in the door itself and are stronger than the fastening that is attached near the doorknob. 


Your door should have a mortise lock at the bottom and the top of the door, bolstering its stability. Locking these at the same time creates a three-point locking system that is difficult to break into. You can also use double-cylinder deadbolts that run vertically and that lock the two doors together.

How To Secure French Doors: Equipping Your Door with an Alarm System

Fortifying your French doors is an important first step, but you will want to add other layers to your protection strategy, and that includes installing an alarm system. This will ensure that if someone goes prowling around your home, it will cause an ear-splitting beep to fill the air. 


This will prompt any sensible intruder to take flight in the other direction, and it’ll also massively increase your chances of securing a successful prosecution. You might consider advertising that the door is alarmed on the outside, this will decrease burglars' hope to enter your home.

How To Secure French Doors: Installation of Security Cameras

Adding CCTV cameras in the doorway is a must-have! Position your cameras in a spot near the French doors so you can see anyone outside. You can put one for your main entry door,  your patio door, and even for the doors leading to the back yard.


The good thing about CCTV cameras is they have night vision, so you can see anyone suspicious very clearly. 


As we are now living in a high-technology world, did you know that some security cameras already come with a motion-activated system? You’ve heard it right! And you can also link it to a mobile device, so you can view your property anytime, anywhere you are.

How To Secure French Doors: Invest in Thick Doors

Having a thicker door is always a benefit to any household. Usually, French doors are made with wood, so you can invest in a thicker wood, or you can even invest in a type of metal to help with the integrity of your door. You can also get the wooden door reinforced with a steel frame if that idea sounds better to you.


You can still enjoy the beauty of your French doors with the steel frame around the wood, while helping to further delay those burglars that are trying to get in.

How To Secure French Doors: Consider Adding Security Bars

We’ve talked about deadbolts, but now it’s time to talk about security bars. 


French doors are particularly vulnerable to being kicked-in. You can make this much more difficult for a would-be intruder by adding a security bar. This is one of the easiest and most effective methods to use. 


A security bar is propped at an angle between the door and the floor, preventing the door from opening. As an extra measure, some security bars also include an alarm, which has the effects of both warning you of the break-in attempt and frightening the potential burglar.

How To Secure French Doors: Invest in High-Security Locks and Hinges

Any door's security can be improved with better locks and hinges, including French doors. Invest in high-quality security hardware. It sounds obvious, and it should be, yet so many people don’t change the weak and inadequate locks and hinges that come with these doors. 


Another big problem is short hinge screws. The hinges on your doors should have screws that are at least three inches long, which will keep the doors more securely connected to the doorframe. 


You want to be sure that your French doors open outward, that way when you’re installing them, the hinges will be on the inside, which in turn will help keep the hinges from being tampered with.

How To Secure French Doors: Invest in High-Security Locks and Hinges

You can often get high enough security on a French door if you employ a three-point locking system. However, that’s sometimes not enough for homeowners on how to secure French doors, because if you don’t have the right lock, an intruder can break it, bypass it, or simply kick the door down. 


So if you want to install a high-security French door lock, we recommend that you go for it. After all, security for the people inside your home and peace of mind are two things that are always worth it.
