If it's worn or loose, out, it can lead to drafts, as well as other issues. Begin by identifying the brand of window and the manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Take the sash off and mark its width and height so that you can find a replacement weather stripping that matches.
Then, take it off and set it on a table so you can access all four sides. If your sash is double-hung, you'll also need to remove the weights as well as the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. After you've removed the sash, use a utility knife to remove the weather stripping that was formerly in place at the corners, and then remove it by hand or using a putty blade.
When the sash is clean, you can replace the parting stops. These are long pieces that divide the sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you could also use a piece of scrap wood.
After removing the parting stops and cutting them to the desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty knife, and let it dry at least one day. When the putty is fully cured it is possible to apply an acrylic latex topcoat. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes is prone to wearing out from age and use, and the result can be a window or door that can't be opened or closed easily. The good news is that fixing and replacing this hardware is generally quite simple and inexpensive. If you're having difficulty opening a sash spray some grease into the jamb channel. Then, you can slide the sash up and open to see if that fixes the problem. If the problem persists it's most likely that the sash balance is off.

Window sashes should open and close without much effort. However, this can be a challenge if the weights have been worn out or the sash connecting rail isn't coated. This issue could be caused by a number of things, such as the lack of maintenance or the wrong weight rating for the specific sash.
If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to drag and eventually land on the frame in the corner that's in the opposite direction of 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 is screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows especially in older houses, could be difficult to open and close. In many cases just a few easy fixes can allow these windows to operate smoothly and save homeowners money on energy costs.
It is essential to have the tools you need before you start. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1).

Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or just to keep the windows functional by replacing worn out sash weights will improve sash operation and help reduce energy consumption. Sash weights are composed of iron or lead cylinders that are encased in a hidden cavity and connected by ropes to the movable window sash. They provide counterbalance that allows the window to be closed and opened without the use of electrical or mechanical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to recover, so you will want to find a new one that fits correctly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord.
Older wood windows are joined with 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 them have a large diameter on one side and a smaller diameter on the other, which is why it is essential to remove the small-diameter sides first. Later sashes utilized glue instead of pins. They can be cut by using a knife or mallets.
Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the interior workings.
After you have the sash stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with the new. Weigh the sash first to ensure that the weights you've got may not be the right size. After the new weight is in place you can tie a string around it and thread it through the sash pulley. Then, you can nail the string to the frame, but only leave a few inches of string sticking out from the head for future adjustments.
Sash Cords
Most old double-hung windows come with a chain or cord attached to the weights that helps keep the sashes in balance in the jamb. Over time, these cords may become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash, and keep it in position when it is opened.
To replace sash cords, the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and will need to be removed or relocated. It is possible to take them out using a hammer or chisel, but it is always better to lay out dust sheets before starting any work.
After removing the access panel, you can begin working on the sash. Use a flat bar or chisel to pry the tiny parting beads from their grooves. It is important to be patient, as these are often stuck or nailed to the floor. If the sash is still in place, pry the mortise and tenon joints free with a hammer or screwdriver and then take out each wood peg. You should be able to move the sash back and forth without difficulty, though it may require oiling if it seems stiff.
Determine the length of sash chain/sash cord needed to reach the sash slot at the bottom of the pulley at the top of the jamb. Cut the chain or cord and fix it as described in the previous step. You can do this with nail, hammer or screws. However, nails are less likely than screws to cause damage.
It's best to leave the original weights if you've purchased a kit to replace the counterbalance that was previously installed. They're not expensive and are easy to install if you purchase them from salvage shops for architectural use. Based on the size of your window, one or two sashweights could be needed to keep it in an open position.
