Window Mechanisms

Broken window mechanism?


We can fix your broken uPVC window mechanisms for a fraction of the cost of buying new windows.

Selkent Glazing & Locks offer a full repair and replacement service on window mechanisms and we replace only the broken parts, saving you the expense of fitting new windows. We supply and fit window mechanisms in Swanley, Orpington, Dartford and the surrounding areas.

At some point, windows which have been in use for a long period of time will start to show signs of wear and tear. Window mechanisms can fail for a wide variety of reasons. Age can wear down the mechanism or in some cases an attempted break-in can lead to damage requiring complete replacement, or simply the mechanism has never been lubricated.

A upvc window mechanism is the gearing part inside a window frame that’s driven by a handle and secures the window shut. Commonly called upvc mechanisms but also known as espagnolette (espag) window locks, these mechanisms are one of the most common parts to break in a uPVC window. A common indicator that the window mechanism needs replacing is that it will start to become more difficult to open and close before it breaks.


When a window mechanism is broken it will leave you with two situations:

  • The window is closed and you’re unable to open it, or

  • The window is left open and you’re unable to lock it.

In either situation we are on hand to help. We carry a wide range of window mechanisms and can supply and fit them in most cases the same day.
