Then, remove the sash and mark its width and height, so you can find new weather stripping that matches.

Then, you can remove the sash from its holder, and place it on a flat surface to allow you to reach all four sides. If the sash is double-hung, you'll have to remove the weights as well as their ropes that should have fallen into the pocket of the jamb liner. After removing the sash using the utility knife, remove the old weather stripping by hand or with a putty knife.

Once the sash is clear it is time to replace the parting stops. These are long pieces that divide the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also substitute for a scrap piece of lumber.

After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty tool and allow it to dry for at least one day. Once the putty has fully cured it is possible to apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a new appearance.

To remedy the issue make sure the sash is aligned in the frame opening and then take it off. If the sash was screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2).

The sash weights are usually neglected or ignored by homeowners and then turned into scrap when they fail; therefore you might need to locate replacements.

A sash weight that has fallen out of the cavity is difficult to retrieve, so you will want to find a new one that fits correctly. You will also require a fresh piece of string, a length of sashcord and some sashpulleys to tie the new weights to the cord.

Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of these pegs have an enormous diameter on one side and a smaller diameter on the other side, so it is important to remove the smaller-diameter sides first. Later sashes used glue instead of pins. They can be cut with a knife and mallet.

Once the sash has been released, you can remove sash stops and access the weight pockets. This is usually done via a small hole at the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inside workings.

You might be able to use a hammer or chisel to prise them off, but it's always better to lay down dust sheets prior to commencing any work.

If the sash is still in place, pry out the mortise and the tenon joints by using pin punch and hammer or screwdriver, and then take out the wood pegs attached to the components. You should now be able to move the sash back and forth freely, although it will probably need some lubrication if it feels stiff.

Take a measurement of the length of sash cord/chain needed to reach the sash slot on the bottom, and the pulley on the top of the jamb. Cut the cord or chain, and then fix it using the previous step.
