A Comprehensive Guide to Sliding Door Security

Importance of Sliding Door Security

The importance of sliding door security cannot be overstated. Sliding doors, particularly those made of glass, are common in many homes and businesses due to their aesthetic appeal and functionality. However, their popularity also makes them attractive to potential intruders. Therefore, it’s crucial to ensure they are as secure as possible to protect your property and loved ones.

Many people underestimate the significance of sliding door security. They believe that because these doors are often located at the rear of a property, they are less likely to be targeted by burglars. This is a dangerous misconception. In fact, the very features that make sliding doors attractive – their large size and glass composition – can also make them vulnerable to break-ins.

Remember, a secure home isn’t just about having a high-tech alarm system or sturdy front door. It’s about taking a holistic approach to security, which includes securing all potential entry points, including sliding doors. Ensuring proper sliding door security is a crucial step towards achieving a secure home or business.


Why do burglars like sliding doors?

Oh, the fascination of burglars with sliding doors! It’s like a thrilling subplot in a gripping crime novel. What’s so special about sliding doors, you ask? Well, let’s dive into the intriguing world of burglaries and their strange preference for these particular types of doors.

Sliding doors, you see, are like an inviting gateway for burglars. They might as well have a welcome sign saying “easy access here!” Why is that, you wonder? Well, it’s mainly due to their design. Sliding doors are typically made of glass, which not only provides a clear view of the home’s interior but also makes it easier to break into. A simple smash and voila! They’ve gained entry.

And there’s more! You won’t believe how easy it is for burglars to lift these doors off their tracks. It’s like child’s play to them! In most cases, all they need is a little bit of force and the right angle, and they’re in. And believe it or not, many homeowners unknowingly make the job even easier by failing to install proper locks on these doors, making them a burglar’s dream come true. But get this! Even with a lock installed, most sliding doors can be jimmied open with simple tools or bypassed entirely by removing the door from its track. Yes, you heard it right! It’s like giving burglars an open invitation!

So, it’s no surprise that sliding doors are cherished by burglars. They offer an irresistible combination of easy access and low risk, making them a top choice for break-ins. It’s like they’ve hit the jackpot in the burglary world. So next time you’re considering installing sliding doors, remember to take necessary security measures to keep your home safe and deter those ever-excited burglars.

Understanding Sliding Glass Door Vulnerabilities

Before we can effectively secure our sliding doors, we must first understand their vulnerabilities. Sliding glass doors are often seen as weak points in a home’s security due to several reasons.

Firstly, sliding glass doors are typically located at the back of a house, hidden from street view. This provides potential burglars with the privacy they need to attempt a break-in. Secondly, the large panes of glass in these doors can be easily shattered. While this requires a certain level of audacity, it is unfortunately not unheard of.

Thirdly, the latches on sliding doors are often not as robust as those found on standard doors. They can be easily jimmied open with basic tools, or even by an experienced hand. Lastly, sliding doors can be lifted right out of their tracks from the outside if not properly secured. This is a surprising vulnerability that many homeowners are unaware of.

Guide to Secure Sliding Glass Doors

Having identified the vulnerabilities of sliding glass doors, let’s now explore some effective ways to secure them. There are several methods available to improve sliding door security, and it’s often best to use a combination of these for maximum protection.

The first step is to reinforce the glass. You can do this by applying a security film on the inside of the door. This film holds the glass together even when shattered, making it difficult for a burglar to gain entry. Alternatively, you can install laminated or tempered glass, which is much stronger and harder to break than regular glass.

Next, consider improving the locks. Many sliding doors come with simple latches that can be easily forced open. Consider installing a double bolt lock, which requires a key to open from both inside and outside. This significantly improves your sliding door security.

Lastly, ensure your door cannot be lifted off its tracks. You can do this by installing anti-lift devices such as top and bottom track screws. These secure the door to the track and prevent it from being lifted off.

The Role of a Security Bar in Sliding Door Security

One of the most effective ways to secure a sliding door is to use a security bar. A security bar for a sliding door is a bar or rod that is placed in the track of the door. When the bar is in place, the door cannot be slid open, even if the latch is unlocked.

A security bar adds an extra layer of security to your sliding door. It is a simple yet effective device that can withstand substantial force, making it difficult for intruders to force their way in. The bar can be easily engaged and disengaged by the homeowner, providing convenient security.

Furthermore, a security bar acts as a visual deterrent. When a potential burglar sees the bar, they know that breaking in won’t be easy. This can discourage them from even attempting to break in.

How to Choose the Right Sliding Door Security Bar

When it comes to choosing a sliding door security bar, there are several factors to consider. Firstly, the bar needs to be strong enough to withstand force. A bar made from steel or aluminium is usually a reliable choice.

The length of the bar is also critical. It needs to fit snugly in the track of your sliding door. Some bars are adjustable, which is a good option if you’re unsure of the exact size you need.

The bar should also be easy to install and use. If it’s too complicated, you might not use it consistently, which could leave your home vulnerable. Look for bars that can be easily placed and removed without requiring any tools.

Lastly, consider the aesthetics of the bar. While security is the primary concern, you don’t want the bar to be an eyesore. Choose a bar that matches the style and colour of your door.

Tips for Enhancing Sliding Glass Door Security

Beyond installing a security bar, there are additional steps you can take to enhance your sliding glass door security. One simple but effective measure is to use window coverings. Blinds or curtains can prevent potential burglars from seeing inside your home or office, reducing the likelihood of a break-in.

Another tip is to install a security alarm system and ensure it includes your sliding doors. If an intruder tries to force open the door, the alarm will sound, alerting you and potentially scaring off the burglar.

Don’t forget about the importance of regular maintenance. Keep the tracks of your sliding door clean and well-lubricated to ensure it operates smoothly. A poorly maintained door is easier to force open.

Additional Measures to Boost Sliding Door Security

To truly boost your sliding door security, consider implementing additional measures. One such measure is installing security cameras. Cameras act as a powerful deterrent to potential burglars. Even if a break-in occurs, the footage can provide valuable information to law enforcement.

You can also install motion sensor lights near your sliding doors. These lights turn on when movement is detected, potentially startling an intruder and causing them to abandon their plans.

Finally, remember that security isn’t all about hardware and technology. Never leave your sliding doors unlocked when you’re away from home, and always ensure they are completely closed. It’s easy to become complacent, but remember, the best security measures are only effective if used consistently.

Professional Services for Sliding Door Security

While there are many measures you can take yourself to improve sliding door security, it’s also worth considering professional services. A professional can assess your current security measures and identify any potential vulnerabilities. They can also recommend the best security solutions for your specific needs and install them correctly.

Professional services can also offer maintenance and repair for your sliding doors. This ensures they remain in good working order, which is essential for maintaining security.

While professional services may involve an upfront cost, the peace of mind they offer can be priceless. Remember, the cost of a break-in can be far greater than the cost of preventing one.


Securing your sliding doors is a critical component of home or business security. By understanding the vulnerabilities of your sliding doors and taking proactive measures to enhance their security, you can significantly reduce the risk of a break-in. Whether you choose to install a security bar, reinforce the glass, or employ professional services, every step you take towards improving your sliding door security is a step towards a safer home or business. Remember, security isn’t a one-time task, but an ongoing commitment. Stay vigilant, stay safe. For more info you can read here and here.
