Why customers use Armalock Locksmiths for window locks
Secure closure restored
We focus on reliable locking as well as getting the window moving again.
Alignment checked too
A repaired mechanism should not be left working against avoidable frame strain.
Useful everyday ventilation
The goal is normal opening and closing, not just a window that is less awkward.
Getting a stuck or insecure window working properly again
A window that will not open, will not lock or feels wrong in the handle can affect security, ventilation and daily use all at once. We deal with uPVC window faults by looking at the handle, spindle, locking mechanism, keeps and sash alignment rather than assuming the first obvious part is the only problem. With Armalock Locksmiths, the aim is to restore controlled opening and secure closure so the window works as it should, without leaving you to put up with a jammed sash or a catch you no longer trust.
Repair choices shaped by wear and alignment
Some windows need a straightforward adjustment. Others need the failed locking part repaired or replaced. Correct alignment matters because a mechanism under strain can quickly start showing the same symptoms again after a basic fix. We check how the sash meets the frame and how the locking points engage before final testing. Armalock Locksmiths keeps the advice practical, so you know whether the issue is mainly in the hardware, in the fit of the window, or in a mix of both.
Frequently asked questions
Can you help if my uPVC window is jammed shut?
Yes. A jammed window can be caused by the handle, spindle, internal mechanism or by the sash meeting the frame badly. We assess the way the window is sitting and how the hardware is behaving so the fault can be traced before repair or replacement is chosen.
Why does my window handle feel stiff or loose?
That can point to wear in the handle itself, a problem with the spindle or resistance elsewhere in the locking setup. If the sash is out of line, the handle may be working harder than it should. We check those connected parts rather than treating the feel of the handle in isolation.
Will a repaired window lock still open smoothly afterwards?
That is the aim. We want the window to open in a controlled way, close properly and lock without excess force. Final checks matter because a lock that technically works but still strains against the frame is more likely to cause trouble again later.
