Sliding patio doors are undoubtedly a wonderful aesthetic touch to any home. They provide lots of natural light in the house while providing a great view of the outdoors. But the aesthetic perks come with one major setback – home security. Sliding doors are a prime access point for burglars. Tossing a brick right through the glass, lifting the sliding door off its track, and bypassing the latch, most factory-installed patio doors are a break-in incident waiting to happen.
How to Secure Sliding Doors: 5 Expert Tips
Most sliding glass doors have three exploitable weaknesses: the lock, the track, and the glass. The standard factory latch can often be jiggled open in seconds. The door can be physically lifted off its track with basic tools. And the glass, while tempered, can be smashed quickly. The good news is that each of these vulnerabilities has a straightforward fix, and as a homeowner, it’s worth taking the necessary steps to secure sliding patio doors from intruders. Here are some expert tips on securing patio doors without sacrificing aesthetics:
Apply Shatterproof Glass Film
Smashing a glass door is as easy as hurling a brick at it. A shatterproof window film solves this weakness by preventing the patio door from completely falling apart. It may not wholly deter unwelcome visitors, but it slows them down. Window films have privacy properties (they’re only transparent one way) and UV ray protection. For maximum glass protection, consider upgrading to impact-resistant or laminated glass, which is far harder to breach than standard tempered glass.
Blocking Tracks With Bar for Patio Doors
Factory-installed patio glass doors typically have a latch as the only form of security. While this works in keeping the door closed and in place, it does little to protect the home from invaders.
One of the simplest and most effective things you can do is place a security bar or wooden dowel in the bottom track of the door. This prevents the door from being slid open even if the latch is bypassed. Cut a piece of wood or metal pipe to fit the width of the track and lay it in place when the door is closed. Commercial blocking bars are also available and some include anti-lift features. Some people may prefer a Charlie bar installed at waist level, which swings in and out of place as needed, without needing to bend down.
Upgrade to a Deadbolt Lock
The latch on a sliding glass door is not very secure. To reinforce it, get a deadbolt lock that provides a higher level of security. There are tons of options in the market, so it’s best to hire a quality door contractor who can recommend the most secure option and ensure proper installation.
Add a Home Security System and Motion-Sensor Lighting
It’s advisable to get a home security system installed and monitored by a qualified professional. This system may include glass break sensors (entry sensors), an alarm, and a security camera. Glass break detectors in particular are highly effective. Seeing a glass break sensor is enough to make intruders move on to an easier target. The idea is to deter burglars (Intruders don’t want to be caught) and help homeowners respond swiftly by alerting the authorities.
Stop the Door From Being Lifted
Burglars can lift a sliding door off its track using a crowbar, reversing the same process used to install it. To prevent this, insert screws into the upper track above the sliding panel. Leave just enough clearance for the door to slide freely but not enough gap for it to be lifted out. This is one of the most overlooked fixes and one of the most effective.
