If the hinge arms of a window begin to lose their elasticity, this could cause the sash to slide and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To remedy the issue ensure that the sash is centered in the frame opening, and then take it off. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2).

Sash Weights
Sash weights can be replaced to improve the operation of your upvc window repairs sash, and also reduce energy costs. Sash weights consist of heavy lead or iron cylindricals that are contained in a hidden cavity and attached by a rope to the movable window sash. They provide counterbalance, allowing the window to be shut and opened without the use of electrical or mechanical devices. The sash weights are usually neglected or ignored by homeowners, and are turned into scrap when they break; therefore you might need to find replacements.
A weight from a sash that fell out of the cavity is difficult to recover It is therefore important to find a replacement that fits correctly. You will also require a new piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights onto the sash cord.
Mortise and Tenon joints are used to join windows made of older wood. Hammers and pins can be used to take out the wood pegs that hold the components together. The majority of these pegs are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised area loose with mallets.
After the sash has been removed then you can take out the sash stop and access the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. This hole is covered by an access panel made of wood which can be removed so that you can see the inner workings of the frame.

It is possible to remove them with the hammer or chisel but it is always better to lay out dust sheets before beginning any work.
After removing the access panel, you can begin to work on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is important to take your time because they are usually wedged or nailed in place. If the sash remains in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, then unhook the wood pegs attached to each piece.

Take a measurement of the length of the sash chain or sash cord needed to reach the sash slot on the bottom from the pulley at the top of the jamb. Cut the cord or chain and secure it as in Step 6 above. You can employ a hammer, nail or screws, but nails are less likely to cause damage.
