Start by identifying the window brand and the glass manufacturer's date (etched on the glass's corner or on the aluminum spacers between panes). Remove the sash, and mark its width and height so that you can find a new weather stripping that is compatible with the original.
Then, remove the sash from its holder and place it on an even surface that allows you to reach all four sides. If your sash was double-hung, remove the ropes and weights that should be buried inside the jamb lining. After upvc window repairs 've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners, and then take it off by hand or using a putty blade.
When the sash is clean it is time to replace the parting stops. These are long pieces of wood that are used to separate the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you can also use for a scrap piece of lumber.

Sash Hardware
The hardware that supports window sashes is susceptible to wear and tear from time and usage, and the result can be a window or door that isn't able to open or close easily. The good thing is that fixing and replacing this hardware is typically very simple and cost-effective. If you're having difficulty opening the sash, spray some lubricant into the jamb channel. Then, slide the sash out to see if this resolves the problem. If not, the issue is likely with the sash balance and you'll need to take out the sash to access this hardware.
Ideally, window sashes must be able to open and close with minimal effort but this can be an issue when the weights wear out or if the sash's meeting rail isn't properly coated. This issue could be caused by a number of things, such as lack of maintenance or by a mismatched weight rating for the particular sash.
If the hinge arms on windows begin to slide, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To address this issue, first make sure the sash fits squarely in the opening of the frame and then take it out of the window. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older homes, may be difficult to open or close. In many cases just a few easy fixes can allow these windows to operate smoothly and help homeowners save money on energy bills.
It is essential to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will allow you to put the channel in the correct place when you are finished.

The nozzle shield of the heat gun and medium setting will soften any putty that has been hardened. Remove the old sash, and store it in an bag that is labeled.
Sash Weights
Sash weights can be replaced to improve the performance of your window sash and reduce the energy cost. Sash weights are composed of iron or lead cylinders that are encased in a concealed cavity and are connected via ropes to the moveable window sash. They provide counterbalance that allows the window to be closed and opened 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. Consequently you might need to find replacements.
A weight from a sash that fell out of the cavity is difficult to retrieve, so you will want to locate a new one that fits correctly. You will also need an additional piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights to the sash cord.
Older windows made of wood are joined using mortise and tenon joints. The wood pegs that hold the parts together can be removed by the use of a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller diameter on the other, 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 through the glue line with an instrument, and then tapping the mortised section loose using a mallet.
After the sash has been removed and removed, you can take off the sash stop and access the weight pocket. This is usually done via an opening in the bottom of each jamb. The hole is then covered with an unfinished 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 remove the weight of the old sash and replace it with the new. Be sure to weigh the sash before you begin, as the old weights may be different in size from the one you need. Once the new weight is installed, thread a string through the sash pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches protruding at the head of the string to allow for future adjustments.
Sash Cords
Most double-hung windows of the past have a cord or chain attached to the weights which supports and keeps the sashes balanced in the jamb. Over time these cords can break, making it impossible to raise the window. A new sash cord will restore the ability to move the sash up and down and hold it in place 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 installed by screws or nails and must be removed or relocated. It may be possible to remove them using an axe or hammer, but it is always better to lay out dust sheets prior to starting any work.
After removing the access panel, you are able to begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. It is essential to take your time as they're often wedged or nailed in place. If the sash remains in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs attached to the components. The sash should move around freely now, however it may require some lubrication to make it feel less stiff.
With the sash in an open position Take a measurement of the sash chain to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord/chain, and then attach it as described in the previous step. You can use either a hammer, nails or screws. However, nails are less likely than screws to cause damage.
It is best to keep the weights that came with the original counterbalance unless you've purchased a kit that will replace the counterbalance.
