These are long pieces that divide the sashes. Pam likes to replace these with standard ½-inch by ¾-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.

Sash Hardware The hardware that supports window sashes is susceptible to wear and tear due to the wear and tear of use, and the result can be a door or window that won't open or close easily. It's good to know that replacing or repair of this hardware is typically straightforward and cost-effective. If you're having trouble opening a sash, spray some grease into the jamb channel. Then, slide the sash out to see if this resolves the issue. If the issue persists it's most likely that the sash balance is off. You will need to take off the window sash in order to get access to this part of the hardware. The ideal situation is for window sashes to swing open and closed without effort, but this is a difficult task if the weights become worn or if the sash's meeting rail isn't properly coated. This issue could be caused by many factors such as the lack of maintenance or an unmatched weight rating. If the hinge arms of a window are starting to slide, this could cause the sash to drag and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To fix the problem, make sure that the sash is centered in the frame's opening and remove it. If the sash is fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3). Due to hinges that are sagging, and a general lack of energy efficiency, older windows especially in older houses, could be difficult to open or close.

Sash weights are heavy lead or iron cylinders that are enclosed in a concealed cavity and attached to the movable the sash with rope. These weights function as counterbalances, which allows you to open and close the window without requiring mechanical or electrical devices. When they fail, sashweights are usually left unnoticed or disabled by homeowners. A weight from a sash that fell out of the cavity is difficult to get back It is therefore important to find a new one that fits properly. You will also require a new piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights the sash cord. Mortise and Tenon joints can be used to join old wood windows. Pin punch and hammer can be used to take out the wood pegs that hold the components together. Most of these pegs have an enormous diameter on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter sides first. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised part loose using a mallet. Once the sash is freed, you can remove the stopper on the sash and get access to the weight pocket. This is usually done via tiny holes in the bottom of each jamb. The hole is then covered with 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 has been removed, you can take off the old weight and replace it. First, weigh the sash, as the weights you have may not be of the right size. Once the new weight is in place, tie a string to it and then thread it through the pulley for the sash. Then, you can nail the string to the frame, leaving a few inches of string protruding from the head for future adjustment. Sash Cords In most old double-hung window, a chain or cord is affixed to the weights. This helps keep the sashes within the jamb level. As time passes, these cords can become damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash up and down and keep it in place when it is opened. To replace sash cords the first step is to remove the access panels from the jambs. They are typically attached by nails or screws and must be removed. It is possible to take them out using an axe or hammer, but it is always better to lay out dust sheets prior to starting any work. After the access panel has been removed, you can start working on the sash. Utilize a flat bar, or chisel to pull the tiny parting beads from their grooves.
