Then, take the sash off and mark its height and width, so you can find the appropriate weather stripping replacement to match.
Then, remove the sash from its holder, and place it on an even surface that allows you to access all four sides. If your sash has been double-hung, remove the weights using their ropes that should have fallen into the pocket in the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the weather stripping that was formerly in place at the corners, then remove it manually or using a putty blade.
After the sash has been cleared, you can replace the stoppers that separate the two sashes. These are long pieces of wood that are used to separate the two sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.
After removing the stopper and cutting it to length, apply a thin coat of glazing compound over the bottom of the sash.

If the hinge arms of a window begin to sag, this can cause the sash to slide and eventually hit the frame in the corner opposite the hinge arm (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash has been 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).
Due to sagging hinges, and a general lack of energy efficiency, old windows particularly those in older houses, could be difficult to open or close. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly again and help homeowners save money on their energy bills.

Sash Weights
Sash weights can be changed to enhance the efficiency of your window sash and reduce the energy cost. Sash weights are heavy lead or iron cylinders enclosed in a hidden cavity and connected to the movable window sash using rope. They function as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled by homeowners.
It is difficult to recover the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys to secure the new weights to the cord.
Older windows made of wood are joined using mortise and tenon joints. The wood pegs that keep the parts together can be removed with the use of a pin punch and hammer. The majority of them have a large diameter on one side and a smaller diameter on the other, so it is crucial to take out the smaller-diameter ones first. Sashes that were made later in the century utilized glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised part loose using mallets.
After the sash is removed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inside workings.
After the sash has been stopped and the access panel is removed, you can take off the weight you used and replace it. Weigh the sash first because the weights you've got may not be of the right size. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches protruding at the end of the string to allow for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is attached to the weights. This supports and keeps the sashes in the jamb level. 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 upwards and downwards and will keep it in its place when opened.
The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. They are typically installed by screws or nails and will require to be removed or repositioned. You may be able to use a hammer or chisel to prise them off however, it is always best to lay down dust sheets prior to starting any work.
After removing the access panel, you are able to begin to work on the sash. Take the narrow beads (also called "tie rails") out of their grooves with flat bar or chisel. It's important to be patient, as these are often wedged or nailed in place. If the sash remains in place, pry out the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then remove the wood pegs on each component. The sash should be able to move freely, however it may require some lubrication to feel less stiff.
Determine the length of the sash chain or sash cord needed to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the cord or chain and fix it as described in Step 6 above. You can do this with nail, hammer or screws. However, nails are less likely to cause damage.
It's best to leave the original weights if you have purchased a kit to replace the counterbalance that was previously installed.
