How to Make It Harder for Thieves During the Holidays

But still easy for Santa!

Locks, locks, locks! Locks are your first line of defence! But what about your window locks, and sliding door locks?!

In most homes, windows are potentially the weakest security link. Thieves after an easy target, notably take full advantage of this knowledge with most premises being accessed more often through windows rather than doors.

While people pay a lot of attention to door locks, carefully choosing deadlocks and other security systems such as security doors, they quite often miss the importance of window locks. Most house windows these days are constructed in aluminium and incorporate either a horizontal or vertical sliding function.

The choice of type of sliding window lock for your house can be just as paramount to the security of the premises as choosing the right type of lock for your door. Different window locks have different strength ratings, which is an important factor in choosing the most effective locks for your premises.

As well don’t forget your sliding doors. Sliding door locks are used to secure sliding doors such as patio and screen doors. Sliding windows also have the advantage that they can be ‘locked in an open position’ to still allow fresh air to come into the room. Sliding doors have a bonus that with the right locks, they can also be left in a ‘locked open position’, at just the right size for your cat to come back in out of the heat, while keeping unwanted humans out!

Patio doors and sliding windows are also relatively easy to lift out of their frames. A thief can do it by just lifting them up out of the frame. If secured by an effective sliding window or door lock, it becomes virtually impossible to remove the door or window from the frame. As well, when securing non-sliding windows and patio doors, attention should be paid to the hinges as well as the locks, making sure extra long and strong screws are used to secure the hinge plate to the frame.

  • For Sliding windows and doors, keyed push-lock or keyed security bolts are most effective.
  • For Sash windows, keyed sash locks or keyed window bolts are effective.
  • And for Awning and Casement windows, lockable fastener, lockable winder or keyed security bolts are the best line of defence.

Ultimately, a good security strategy for windows and sliding doors is to install strong, visible locks, suitable for your premises. Make your home or premises unattractive and too much work for would be thieves - don’t overlook your windows and sliding door security! Window locks can be a simple, affordable yet highly effective deterrent for potential thieves
