The first step to sash

To fix it, start by determining the brand of your window and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off, and mark its width and height so that you can purchase new weather stripping that is compatible with the original.
Next, remove the sash and place it on a work surface so that you can reach all four sides. If your sash has a
double glazed window repairs-hung, you'll have to remove the weights and their accompanying ropes that should have fallen into the intended pocket in the jamb liner. Once you've taken the sash off, use a utility knife to cut away the weather stripping from the corners, then remove it manually or with a putty knife.
After the sash has been cleared it is time to replace the parting stops. These are long pieces wood that divide the two sashes. Pam prefers 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 stopper for the parting and trimming it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a day. After it has fully dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that holds window sashes is susceptible to wear and tear due to the wear and tear of use and the result could be a

If a sash is difficult to operate try spraying grease into the jamb channel then open it to see if that solves the issue. If the problem persists, it is most likely the sash balance. You will need to take off the window sash in order to access the hardware.
Ideally,
upvc window repair sashes must move open and shut with minimal effort however, this can be a difficult task when the weights are worn or if the sash that joins rail isn't properly glazed. This can be due to various reasons such as an absence of maintenance or an unmatched weight rating.
If the hinges on the window begin to move, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is centered in the frame opening, and then remove it. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Because of sagging hinges and a general deficiency in energy efficiency, windows that are old particularly those in older homes, may be difficult to open or close. In many instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.
To complete these repairs to the sash it is essential to have all of the necessary tools lined up before you begin. Mark the hinge channel location on the frame (Photo 1) with pencil. This will make it easier to place the channel in the right place when you are finished. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords which hold it in place. The nozzle shield of the heat gun and medium setting will soften any hardened glue. Take off the old sash and store it in an bag with a label.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or simply to ensure that the windows are functional by replacing worn out weights on sash can improve sash operation and cut down on energy costs. Sash weights consist of heavy lead or iron cylinders that are enclosed in a concealed cavity and are connected via a rope to the movable window sash. These weights function as counterbalances, allowing you to open and close the window without having to use mechanical or electrical devices. When they fail, sashweights are usually ignored or disabled by homeowners.
A weight from a sash that fell out of the cavity is difficult to recover, so you will want to find a replacement that fits properly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the new weights to the cord.
Mortise and Tenon joints are used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs holding the components together. The majority of them have an enormous diameter on one side and a smaller size on the other, so it is crucial to take out the small-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallets.
Once the sash has been released, you can remove the stops on the sash and get access to the weight pockets. This is usually done through an opening in the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the interior workings.
Once 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 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
Most double-hung windows of the past have a cord or chain connected to the weights that helps keep the sashes in balance in the jamb. Over time, these cords could break, making it difficult to raise the window. A new sash cord will give you the ability to move the sash up and down and keep it in position when it is opened.
The first step in replacing cords for sash is to locate and remove the access panels in the jambs. These are usually nailed or screwed in and must be removed or moved. You might be able to use a hammer or chisel for removing them but it's best to lay down dust sheets prior to commencing any work.
After you have removed the access panel, you can begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using flat bar or chisel. These are often wedged in or nailed in, but they can be prised free and it's worth your time here. If the sash remains in place, pry the mortise and tenon joints free using a hammer or screwdriver and then take out each wood peg. You should now be able to move the sash back and forth freely, although it might require lubrication if it feels stiff.
With the sash in an open position, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord or chain and secure it as in the previous step. You can employ a hammer and screws or nails, but nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system, it is recommended to keep the original balancing weights in place. They are not expensive and easy to install if you purchase them from salvage shops for architectural use. Depending on the size and shape of your window you might need to install one or two sashweights in order to keep the sash open.
