7 Practical Ways to Improve Your Window Security
30 January 2026 · 5 min read
Most break-ins exploit easy, avoidable weaknesses. These seven straightforward upgrades make your windows a far less tempting target.
Start with the glass and the locks
Laminated security glass is one of the most effective upgrades — it holds together when struck, turning a quick smash-and-grab into a slow, noisy struggle. Pair it with key-locking window handles, which stop a window being opened even if the glass is reached.
On older windows, worn or broken handles and gearboxes are a common weak point. Replacing them is inexpensive and restores the lock's intended security.
Don't overlook maintenance
Draughty, dropped, or poorly closing windows often do not lock properly, leaving an easy entry point. Servicing the hinges, seals, and mechanisms keeps everything closing tightly and locking as designed.
Check that ground-floor and accessible windows in particular are in good working order, including any that are rarely opened.
Layer up your deterrents
Security works best in layers: good glass, good locks, and good habits. Keep keys out of sight and reach of windows, make sure nothing valuable is on display, and consider obscured or laminated glass for vulnerable ground-floor and bathroom windows.
If you are unsure where your weak points are, a glazier can assess your windows and recommend targeted upgrades rather than a costly overhaul.
