Refurbishing timber sliding sash and case windows in Scotland is a meticulous process that preserves the architectural heritage of historic tenements and townhouses. The following paragraphs outline the typical stages of this specialised restoration work.
A vital part of any refurbishment is the mechanical overhaul, ensuring the sashes slide effortlessly once again. This involves removing the internal baton rods and parting beads to access the weight boxes via pocket pieces.
Old, frayed cotton cords are replaced with high-quality waxed sash ropes, and the original cast-iron or lead weights are re-balanced to match the weight of the glass precisely.
Pulleys are cleaned, lubricated, and sometimes replaced if the wheels have seized. This restorative work eliminates the common “stuck window” problem, allowing the heavy timber sashes to be operated with minimal effort.
