Sash Window Cord & Weight Replacement Edinburgh

A broken sash cord is the most common problem with traditional sash and case windows in Edinburgh. If your window won’t stay open, keeps dropping, or slams shut unexpectedly, a broken or worn sash cord is almost certainly the cause. Cord and weight replacement enquiries are welcome from across Edinburgh. The scope, timing and price should be confirmed after the window has been assessed.

Signs Your Sash Cords Need Replacing

• The window won’t stay open and slides down on its own
• The window is very heavy or difficult to lift
• You can see a frayed or broken cord hanging inside the frame
• The window lists to one side when open
• You can hear the weights moving unevenly inside the frame

How Sash Cords Work

Traditional sash and case windows use a counterbalance system of lead or cast iron weights hidden inside the frame, connected to each sash by a cord running over a pulley. When cords are in good condition, the weights perfectly balance the sashes — making windows effortless to open and hold in any position. Over time (typically 20–50 years), cords stretch, fray and eventually break.
