Remove the sash, and mark its size and width so that you can find a new weather stripping that is compatible with the original.
Then, take the sash from its holder and place it on a flat surface to allow you to see all four sides. If the sash is double-hung, you'll have to remove the weights as well as their accompanying ropes, which should have fallen into the intended pocket in the jamb liner.

Sash Hardware
The hardware that holds the window sashes may wear out over time and with use. This could lead to the window or door that is difficult to open or close. It's important to know that replacing and repair of this hardware is typically simple and inexpensive. If you are having trouble opening a sash, spray some grease into the jamb channel. Then, you can slide the sash out to see if that fixes the problem. If not, the problem is likely to be with the balance of the sash and you'll need to remove the sash to gain access to the hardware.
Ideally, window sashes should be able to open and close with very little effort, but this is an issue when the weights are worn or if the sash that joins rail isn't properly glazed. This problem can be caused by a variety of reasons, such as insufficient maintenance or a mismatched weight rating for the specific window sash.
If the hinge arms on the window begin to move, this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is in the proper position within the frame opening, and then remove it. If the sash has been screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older houses, can be difficult to open and close, due to hinges that are sagging and a general lack of energy efficiency. Many times, a few simple fixes can help these windows function smoothly again and help homeowners save money on energy costs.

Sash Weights
Sash weights can be replaced to enhance the efficiency of your window sash and reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed in a hidden cavity and linked to the moveable the sash with a rope. These weights function as counterbalances and allow you to open and close the window without requiring mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and then turned into scrap when they fail. Consequently, you may need to search for replacements.
A weight from a sash that fell out of the cavity is difficult to retrieve It is therefore important to find a new one that fits properly. You will also require a new piece of string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the parts together. Most of these pegs have a large diameter on one side and a smaller one on the other, which is why it is essential to remove the small-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised part loose with a mallet.
After the sash is removed and removed, you can take off the sash stop and access the weight pocket. This is typically done by drilling tiny holes at the bottom of every jamb. This hole is covered with the wooden panel which can be removed to reveal the interior workings.

Make sure you weigh the sash before you do this, as the weights that were previously used may be different sizes than what you require. After the new weight has been installed, thread a string through the sash pulling mechanism. Then nail the string to the boxed frame, but leave a few inches of string hanging from the head for future adjustment.
Sash Cords

As time passes, these cords may break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its place when opened.
To replace sash cords, the first step is to remove the access panels from the jambs. These are usually installed by screws or nails and will need to be removed or moved. You may be able to use a hammer and chisel to prise them off however, it is always best to lay down dust sheets before starting any work.
