This motion is facilitated by lead or iron weights concealed within a hollow "box" frame, connected to the sashes by durable cords running over wheels.

Specialists frequently use advanced products like Accoya ® wood, a chemically customized wood that is virtually rot-proof and offers incredible dimensional stability.

The Restoration Process

The systematic technique taken by experts typically follows these stages:

1. Assessment: An extensive study to recognize rot, structural damage, and hardware functionality.
2. Taking apart: Careful removal of staff beads, parting beads, and the sashes themselves.
3. Paint Removal and Repair: Stripping layers of old lead-based paint and using epoxy resins or "splice" repairs for damaged wood.
4. Balancing: Re-weighing the sashes and changing the internal weights to make sure the window "drifts" easily.
5. Draught-Proofing: Installing discreet brush strips into the beads and meeting rails to remove rattles and cold air.
