To fix it, begin by finding your window brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width, so you can find replacement weather stripping to match.
Next, remove the sash and set it on a surface to allow access to all four sides. If your sash was double-hung, you must remove the ropes and weights that should have fallen into the pocket in the jamb lining. After you've removed the sash, use a utility knife to cut off the weather stripping that was formerly in place at the corners, then take it off by hand or with a putty knife.
After the sash has been cleared, you can replace the parting stops. These are long pieces that divide the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you can substitute for a scrap piece of lumber.
After removing the parting stops and trimming them to the desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a modern look.
Sash Hardware

To fix the problem, make sure that the sash is centered in the frame opening and then remove it. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).
Windows that are old, especially in older houses, can be difficult to open and close because of sagging hinges and general inefficiency. Many times just a few easy fixes can allow these windows to operate smoothly again and save homeowners money on their energy bills.

Sash Weights

Sash weights are made of heavy iron or lead cylindricals that are contained inside a concealed cavity, and attached by a rope to the movable window sash. They are counterbalancers which allows the window to be shut and opened without the use of electrical or mechanical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they fail; therefore, you may need to find replacements.
A weight from a sash that fell out of the cavity is difficult to recover, so you will want to find a new one that fits properly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.
Older wood windows are joined using mortise and tenon joints. Pin punch and hammer can be used to cut off the wood pegs that hold the parts together. The majority of these pegs are large on one side and smaller on the other. It is crucial to first remove the smaller diameter sides. Sashes that were made later in the century made use of 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.
After the sash is released, you can remove the stops on the sash and get access to the weight pockets. This is usually done via a small hole at the bottom of every jamb. This hole is covered by an access panel made of wood which can be removed to allow you to see the inner workings of the frame.
After the sash has been stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Be sure to weigh the sash before you do this, since the old weights could be different sizes than the one you need.

Leave a few inches of space at the top of the string to allow for future adjustments.
Sash Cords

It is important to be patient because they are usually placed in a wedge or nail. If the sash remains in place, remove the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then remove the wood pegs that are on each piece.
