Take the nail off using needle-nose pliers, then insert it back into the side channel. The knot of the cord should be tucked into the hole, and secure it using a nail set.

Re-install the sash and then install the beads for staff. Be sure to leave plenty of for the cords to ensure proper operation. Reinstall the counterweights and balances. To minimize draughts small amount of decorators caulk could be applied between the staff bead and the box.

Replacing the sash cords is a simple home fix that will solve these issues in a matter of less than an hour.

Remove the staff bead which is what separates the upper and lower sashes. You can remove the bead using needle-nose pliers.

If the sash is still too high to move, you can use your sharp side cutters to cut and remove the old cords. Once the sash has been removed you'll need to take off the access panel inside the sliding sash windows channel to expose the sash weight pockets, the counterweights, as well as the pulley system. If the window is painted you might need to score the seams using a hammer and chisel to remove the access panel without damaging the paint.

After you've removed the access panel, you'll be able to see the two sash weights made of cast iron inside each pocket.

If the sash is still stuck, use a utility knife to cut through any paint layers and remove it. A new set of tilt pins can improve the window's performance.

A sash window functions by compensating the weight of the glass by using weights passed over a pulley system. These weights are usually cast iron and can be accessed from an access panel or pocket cover located within the lining of the box of the window frame. A dividing strip is put inside the window frame to prevent the weights from colliding.

It isn't easy to access these weights, as the upper sash can be sealed with paint and then put in place. However, if you are patient and careful you can take off the sash with a pair of bar clamps that are reversed and break apart, allowing it out of its groove in the rail that connects it.
