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. We carry out sash cord and weight replacement across Edinburgh — quickly, affordably and with a full guarantee.

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.

We use high-quality waxed cotton sash cord — the traditional material that lasts decades with normal use. Our service includes:

• Careful removal of the sash from the frame
• Access panel removal to reach the weights
• Replacement of all cords (top and bottom sash where required)
• Inspection and replacement of damaged pulleys
• Weight check and rebalancing if needed
