How to Reinforce Sliding Doors: Tips for Better Security

Sliding doors are popular for many homeowners because of their aesthetic appeal and functionality. However, they can also be a potential weak point in home security. Burglars often target sliding doors because they can be easily forced open or lifted off their tracks. Fortunately, there are several ways to reinforce sliding doors and make them more secure. In this blog, we will explore some tips for strengthening sliding doors and improving your home security.

Install a Secondary Locking Mechanism

Installing a secondary locking mechanism is one of the simplest ways to reinforce a sliding door. This can be in the form of a bolt lock or a keyed lock separate from the original lock on the door. A bolt lock can be installed inside the door frame and can be easily engaged when the door is closed. A keyed lock can provide additional security by requiring a key to open the door from the outside. These secondary locks can make it more difficult for burglars to enter your home.

Add a Security Bar

Another effective way to reinforce a sliding door is to add a security bar. A security bar is a metal bar placed across the door track to prevent the door from being forced open. These bars can be easily installed and removed and are an affordable way to increase the security of your sliding door. Security bars are available in various sizes and can be adjusted to fit your door track.

Upgrade to Impact-Resistant Glass

Consider upgrading to impact-resistant glass if you have a sliding door with a glass panel. Impact-resistant glass is designed to withstand high-velocity impacts and can make it more difficult for burglars to break the glass and gain entry to your home. This type of glass is also more durable and can provide additional protection against natural disasters such as hurricanes and tornadoes.

Install a Door Sensor Alarm

A door sensor alarm can effectively deter burglars and alert you to any attempted break-ins. A door sensor alarm is a small device installed on the door frame and detects when the door is opened. When the door is opened, the device emits a loud alarm to alert you and your neighbors to a potential break-in. Door sensor alarms are available at various prices and can be easily installed by the homeowner.

Replace Old or Damaged Rollers

Old or damaged rollers can make sliding doors easier to lift off their tracks. If your sliding door is not sliding smoothly or seems loose, it may be time to replace the rollers. New rollers can be easily installed, making it more difficult for burglars to lift the door off its tracks. In addition, replacing old or damaged rollers can improve your sliding door’s overall performance and lifespan.

Reinforcing sliding doors is an essential step in improving the security of your home. Adding a secondary locking mechanism, a security bar, upgrading to impact-resistant glass, installing a door sensor alarm, and replacing old or damaged rollers are all effective ways to make your sliding door more secure. By taking these steps, you can deter burglars and protect your home and your family from potential break-ins. Remember that a bit of investment in reinforcing your sliding doors can go a long way in improving your home’s overall safety and security.


It’s important to note that reinforcing your sliding doors should not be the only security measure you take. It’s also a good idea to install security cameras and an alarm system, and to practice good home security habits such as locking your doors and windows when you leave the house. By taking a multi-layered approach to home security, you can significantly reduce the risk of a break-in and enjoy greater peace of mind knowing that your home and family are safe and secure.
