Pull the sash to the right and take it off the frame. Pull the cord from the bottom of the sash, then cut it and remove any nails that are protruding from the end. Remove the nail using needle-nose pliers and then reinsert it into the side channel. Insert the knot of the cord into the hole and secure it using an nail set.

Re-install the sash and install the beads for staff. Make sure you leave enough slack in the cords to ensure optimal operation. Reinstall the balances and counterweights. To minimize draughts small amount of decorators caulk can be placed between the bead of the staff and the box.

Mix with enough chalk to make the putty pliable and not stick to your fingers. Allow the putty to dry completely before installing the sash again and painting the frame.

Broken sash cords

To balance and support the sashes of old double-hung windows (two sashes) cotton cords or chains are attached to the counterweights. As time passes, the cords could break, which stops the sashes from opening and closing and makes it difficult to raise or lower the window.

When you're done, ensure that the new cord matches with the groove in the sash windows upvc and that it's tied to the frame of the sash by knotting it.

If the sash is still too high to move, you can use your sharp side cutters to cut and remove the old cords.

A new set of tilt pins could also enhance the window's performance.

Weights are passed over a pulley system to balance the weight of a sash window. These weights, which are usually constructed of cast iron, can be accessed through an access panel or pocket located within the lining of the box. A dividing strip is placed inside the window frame to stop the weights from colliding.

Accessing these weights can be difficult as the upper sash has been painted shut and can be nailed in the correct position. If you are cautious and patient, you can take the sash off with a pair of bar clamps that are spread apart. It might take a some jiggling and tapping to get it out but once you've got it removed, make sure to inspect the sash cord and replace it with new rope (not cotton) if necessary.
