After the sash has been cleaned, you can replace parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you can substitute with a scrap piece of wood.
After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty knife, and allow it to dry for at least one day. When the putty is fully cure, you can apply an acrylic latex topcoat.

If the hinges on the window begin to move, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To fix this problem, first ensure that the sash fits squarely in the frame's opening and then remove it from the window. If the sash is secured to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Old windows, especially those in older homes, may be difficult to open and close due to sagging hinges and an overall inefficiency. In most instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner cash on energy costs.
It is important to have the tools you require before you start. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1).

Sash Weights

They provide counterbalance which allows the window to be closed and opened without the use of electrical or mechanical devices. If they fail, sashweights tend to be neglected or not used by homeowners.
A weight from a sash that fell out of the cavity is difficult to recover and you'll need to find a new one that fits correctly. You will also need an additional 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 can be used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of these pegs are big on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Sashes made later in the century used glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised area loose with mallets.
Once the sash has been released, you can remove the sash stops and gain access to the weight pockets. This is typically done by drilling a small hole at the bottom of each jamb. This hole is covered by an access panel made of wood that can be cut off so that you can observe the inner workings of the frame.
After you have the sash stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with the new. Be sure to weigh the sash prior to you do this, as the old weights could be different in size from what you require.

After the access panel has been removed, you can begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with a chisel or flat bar. It is essential to be patient as they're often stuck or nailed to the floor. If the sash remains in place, pull the mortise and tenon joints free using a hammer or screwdriver and then take out each wood peg. The sash should be able move freely, however it may require some lubrication to make it feel less stiff.
Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the chain or cord and fix it as described in the previous step. You can use a hammer, nails, or screws. However nails are less likely to cause damage.
