Burglary

Relying on standard window locks

Windows may be the weakest link in home security, especially if left open and unattended. Make sure all windows are closed and locked before you leave home, even for the shortest errand, and add window dressings and shades to discourage prying eyes.

Modern windows include sash locks, but you can improve security by drilling a hole from front to back where the top and bottom windows overlap and installing a long nail in the hole. If the integrated window lock breaks, the nail will stop the window from sliding open. Security bars on ground-level windows are also an option, but make sure they are fitted with quick-release mechanisms that allow them to be opened from the inside in an emergency.
