Worn sash windows can be one of the easiest ways for a burglar to enter your home. By identifying the worn parts of your sash windows, you can get them repaired as quickly as possible.
Replace the Sash Fastener First
The broken or missing sash fastener will have caused the meeting rail to have had no clamping force at all. In most cases these types of fasteners can be opened with a thin blade (such as a screwdriver) within seconds. Therefore it is best to supply and fit the Locking Fastener with a Key Barrel.
Retension or Replace Sash Cords
A slack or snapped sash cord enables the bottom sash to fall back and sit loose in the window frame. This creates a gap at the top of the sash that can be pushed open from outside. New sash cords are drawn up to clamp the sashes together.
Repair Rotten Stiles and Meeting Rails
Cutting out the soft or shrunk timber and splicing in the correct sized timbers to form a solid stile or meeting rail enables the window to regain the structural resistance required to prevent break-in by jemmy.

Add Staff Bead Stops or Brighton Fasteners
Add Staff Bead Stops or Brighton Fasteners to Sash Windows. A Brighton fastener is screwed into the meeting rails of sash windows. This can act as a secondary locking point for sash windows, and is used by Sash Window Repair London. Staff bead stops are used to stop the lower sash being lifted out of the window frame.
Restore the Parting Bead and Fit Draught Seals
Soft or shrunk timber in the stiles or meeting rails of a sash window will also be vulnerable to jemmies. As stated above, cutting out the worst of the decay and ‘plumbing’ in replacement timbers can solve these problems too. Again, this is fundamental to any serious Sash Window Repair London work.
In summary, by addressing each of the points above in turn, a sash window becomes difficult to force.
