Repairing the Sash

Old wooden windows, even when well maintained and repaired, may not be able to open or close as smoothly as they should.

Once the cord has been secured to the staff bead, you can temporarily pin or nail the weight to the staff bead, and leave the head protruding to keep the weight from slipping out of place in the process.

Sash windows also have an intricate arrangement of timber parts: sash horns that are profiled and sash guts around glazing mouldings made of scotia, precision-made parting beads and staff beads. All of these components must work together seamlessly, requiring millimetre-specific gap sizes and a hidden system of pulleys and weights.
