Remove the sash, and mark its size and width so that you can purchase 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 reach all four sides. If your sash has a double-hung, you'll need to remove the weights and their accompanying ropes, which should have fallen into the pocket that was intended to be in the jamb liner. Once you've taken the sash off and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners, then take it off by hand or using a putty blade.Once the sash has been cleared, you can install the parting stops. These are long pieces of wood that are used to separate the two sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trim from the lumberyard. However, you can also substitute for a scrap piece of lumber.After removing the stoppers for parting 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 knife, and let it dry at least one day. Once the putty has fully dried, you can apply a topcoat of acrylic latex. This will help protect the putty, and give your sash an updated look.Sash HardwareThe hardware that supports the window sashes can wear out over time and use. This could lead to the window or door that is difficult to open or close. It's good to know that replacing or repair of this hardware is typically simple and inexpensive. If you are having trouble opening a sash spray some lubricant into the jamb channel. Then slide the sash up and open to see if that fixes the issue. If not, the problem is likely with the balance of the sash and you'll need to take out the sash in order to access this hardware.Sashes for windows should be able to be able to open and close with minimal effort. However, this could be difficult if the weights are worn out or the sash meeting rail is not properly coated. This issue could be caused by a number of things, such as lack of maintenance or by an incorrect weight rating for a particular sash.If the hinges on a window begin to sag this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash was screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).Windows that are old, especially in older houses, can be difficult to open and close due to hinges that are sagging and a general lack of energy efficiency. In many instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner money on energy bills.To complete these repairs to the sash it is important to have all of the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will help you to position the channel in the right place when you are finished. Remove the sash, and remove all the hardware, including the beads for parting, cords, and chains that help to hold the sash.

Sash weights are heavy, lead or iron cylinders, which are enclosed in a hidden cavity and attached to the movable sash by a rope. They function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners, and are turned into scrap when they fail; therefore you may have to locate replacements.It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits correctly. You will also require a new piece string, a length sashcord and a few sashpulleys to secure the weights you are replacing to the cord.Older wood windows are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed with the use of a pin punch and hammer. The majority of these pegs have a large diameter on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting the glue line using a knife, then tapping the mortised area loose with mallets.Once the sash is freed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually it is done by drilling an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inner workings.After the sash has been stopped and the access panel has been removed, you are able to remove the weight you used and replace it. Make sure you weigh the sash prior to you begin, as the old weights may be a different size than what you require. After the new weight is installed, you can thread the string through the sash pulling mechanism. Then nail the string to the boxed frame, leaving a few inches of string sticking out from the head for future adjustments.Sash CordsIn most old double-hung window, a chain or cord is connected to the weights. This helps keep the sashes within the jamb level. Over time these cords can break, making it difficult to raise the window. A new sash cable will give you the ability to raise and lower the sash, and ensure it stays 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 screwed or nailed in and require removal. You may be able to use a hammer and chisel for removing them however, it is always best to lay down dust sheets before beginning any work.After the access panel has been removed, you can start working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with flat bar or chisel. They are typically wedged into or nailed in, but they can be snipped out which is why it's worth your time here. If the sash remains in place, pull the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. You should now be able to move the sash back and forth freely, though it might require oil if it feels stiff.Take a measurement of the length of sash chain/sash cord required to reach the sash slot on the bottom, and the pulley located at the top of the jamb. Cut the cord or chain and then secure it in the previous step. You can use either nail, hammer or screws. However nails are less likely to cause damage.It is best to keep the original weights if you've purchased a kit that will replace the old counterbalance. It's not too expensive to purchase them from a salvage store and they'll be simple to install once you've got the sash open. Depending on the dimensions and shape of your window, you might need to install one or two sashweights to keep the sash open.
