Traditionally, sliding sash windows were operated by cast iron weights housed in boxes at each side of the window and connected to the sash by cord running over a pulley.
In newer sliding sash windows this has largely been replaced by spiral balances. These use springs inside a PVC tube to counterbalance the sash.
If your window drops or will not stay up, it is probable that the spiral balances need replacing. Over the years they become weak and can eventually snap.
We can replace spiral balances and get your window back to being operational.
We replace worn, weak and broken spiral balances in modern and traditional-style sliding sash windows. Correctly matched balances help the sash move smoothly, stay open at the required height and close properly.
Our spiral balance replacement service is available across Hertfordshire, Bedfordshire and Cambridgeshire, alongside sash cord replacement, draught proofing, timber repairs and glazing.
