A window that won’t lock properly is a genuine security gap, not just an inconvenience. It’s one of the more commonly overlooked entry points when people think about home security, with far more attention usually paid to doors.
Emergency Locks Ltd repairs window locking mechanisms, handles, and hinges on uPVC windows across London.
Handles that won’t turn, or turn without the lock actually engaging, are among the most frequent faults we’re called out for, often caused by a worn internal mechanism.
Locking points that don’t fully engage with their keeps in the frame can leave a window that looks closed but isn’t really secure.
Hinges that have dropped, causing the window to sag or catch on the frame, affect both ease of use and, over time, the ability of the lock to engage properly. This is the same kind of issue we often find when repairing uPVC doors, since the two share a lot of the same hardware.
Mechanisms that have fully seized, sometimes from years without lubrication, can leave a window stuck fully open or fully closed.
Doors get used daily, so a fault becomes obvious fast. Windows, especially on upper floors or rooms that aren’t opened often, can sit with a failed lock for months without anyone noticing, which makes them a quiet target for opportunistic break ins.
If it’s been a while since you checked, it’s worth testing that every window in the house actually locks, not just closes.
For older or outdated hardware specifically, it’s also worth considering a lock replacement rather than just a repair, particularly on ground floor windows.
Every window repair is carried out with security as the priority, not just smooth operation.
We check that the window locks fully once the repair is done, since a window that opens and closes nicely but doesn’t actually lock hasn’t really been fixed.
Where the existing hardware is a known weak point, we can also talk you through high security locking options for ground floor or easily accessible windows, the same standard we’d recommend for a front door facing the street.
