How to secure sliding doors and patio doors against burglars

Sliding doors and patio doors are popular features in many Camberley homes. They bring in natural light, open up living spaces, and provide easy access to gardens. But while they’re stylish and practical, they can also be a weak point in your home security if they’re not properly protected.

At Rocks Locks, we regularly help homeowners reinforce sliding and patio doors to keep intruders out.

Here’s what you need to know to secure yours.

Why sliding and patio doors are attractive to burglars

• Unlike traditional front doors, sliding and patio doors often:
• Sit at the back of the house, away from street view, giving burglars more cover.
• Have large glass panels, which can be smashed to gain entry.
• Use simple latches, which are easier to force open compared to high-security locks.
• If not upgraded, these doors can provide burglars with one of the easiest ways into your home.

Top ways to secure sliding and patio doors

1. Upgrade the locks
   Most standard patio doors come with basic latches that aren’t burglar-resistant. Replacing these with high-security locks or multipoint locking systems makes it much harder for intruders to force entry.
2. Add a security bar or rod
   A simple yet effective measure is placing a security bar or metal rod in the track. This prevents the door from being forced open, even if the lock is compromised.
3. Install anti-lift devices
   Burglars may try to lift a sliding door off its track. Anti-lift blocks or pins make this impossible, securing the door firmly in place.
4. Reinforce the glass
   Large panes of glass are tempting targets. Options include:
   Laminated or toughened glass that resists breaking.
   Security film that holds the glass together even if smashed.
5. Use door sensors and alarms
   Adding a door sensor connected to your alarm system ensures you’ll be alerted immediately if someone tampers with the door.
6. Improve outdoor security
   Burglars don’t like being seen. Simple steps such as motion-activated lighting and trimming back hedges around the patio area can reduce risk significantly.
