• The Sashes: The movable panels (generally top and bottom) that hold the glass.
• Package Frame: The hollow frame that houses the weights.
• Weights and Pulleys: Lead or iron weights linked by sash cables over a pulley wheel, enabling the window to remain open at any height.
• Personnel and Parting Beads: Strips of wood that hold the sashes in place and permit them to slide without rattling.
• The Sill: The bottom-most horizontal part of the frame, a lot of prone to rot.

Wood is an eco-friendly resource. Bring back an existing window avoids the carbon footprint associated with production and transferring brand-new units. Additionally, high-quality Victorian timber (slow-grown softwood or durable hardwood) is often of much greater quality than the timber available in hardware shops today.

• Timber Rot: Moisture typically gathers on the sill or the bottom rail, resulting in fungal decay.
• Rattling and Draughts: Gaps between the sashes and the beads frequently lead to heat loss and sound.
• Snapped Cords: If the cable breaks, the weight is up to the bottom of package, and the window will no longer remain open.

The Restoration Process Explained

An expert repair is an organized process developed to return the window to its initial splendor while boosting its efficiency.
