Then, remove the sash and mark its height and width, so you can find the appropriate weather stripping replacement to match.
Then, take it off and place it on a work surface so you can access all four sides. If your sash is double-hung, you'll also need to remove the weights as well as their ropes which should have slipped into the pocket of the jamb liner. After you've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners, then remove it by hand or using a putty blade.
After the sash has been cleaned, you can replace parting stops. These are long pieces that separate the sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.

If the issue persists it's most likely to be due to the sash's balance. You will need to remove the window sash to get access to this part of the hardware.
The ideal situation is for window sashes to be able to open and close with very little effort, but this is an issue when the weights wear out or if the sash that joins rail isn't properly glazed. This issue could be caused by a number of things, such as insufficient maintenance or the wrong weight rating for the particular sash.
If the hinge arms of a window begin to lose their elasticity, this could cause the sash to slide and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, put in 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. In most instances, a few easy repairs can turn these windows into smooth operators for the first time and save the homeowner money on energy bills.
To complete these repairs to sash it is important to have all the tools needed before you begin. Mark the hinge channel's location on the frame (Photo 1) using pencil.

Sash Weights
If your window sash repairs are to replace a broken cord or just to keep your windows functioning, replacing worn out weights on sash can improve sash operation and cut down on the energy cost. Sash weights are heavy lead or iron cylinders enclosed in a hidden cavity and connected to the movable the sash with a rope. They function as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights are usually ignored or disabled by homeowners.
It's not easy to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also need a new piece of string, a length of sash cord and some sash pulleys to tie the new sash weights onto the sash cord.
Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of them have an enormous diameter on one side and a smaller one on the other, which is why it is crucial to take out the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be cut by using a knife and a mallet.
After the sash is released, you can remove the stops on the sash and get access to the pockets for weights. Usually it is done by drilling an opening in the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inside workings.
Once you have the sash stopped and the access panel removed, you'll be able to remove the weight from the sash and replace it with the new. Weigh the sash first, as the weights you have might not be the correct size. After the new weight is in place, tie a string to it and then thread it through the pulley of the sash. Then, attach the string to the boxed frame. Leave a few inches protruding at the end of the string for future adjustments.
Sash Cords
In the majority of old double-hung windows, a chain or cord is attached to the weights. This supports and keeps the sashes within the jamb balanced. Over time these cords can break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash up and down and will keep it in its position when it is opened.
The first step to replace cords for sash is to locate and remove the access panels in the jambs. watch this video are typically screwed or nailed in and need to be removed. You could use a hammer and chisel to prise them off, but it's always better to lay down dust sheets before starting any work.
After you have removed the access panel, you can begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. These are often wedged in or nailed, but they can be prised free and it's worth your time. If the sash remains in place, pull the mortise-and tenon joints using a hammer or screwdriver and then remove each wood peg. The sash should be able to move around freely now, however it may require some lubrication to make it feel less stiff.
Determine the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord or chain and then attach it as described in the step 6 above. You can use either a hammer, nails or screws. However, nails are less likely to cause damage.
