Start by identifying the window's brand and the glass manufacturer's date (etched on the glass's corners, or the aluminum spacers between panes). Take the sash off, and mark its size and width so that you can get replacement weather stripping that matches.
Then, take it off and place it on a surface to allow access to all four sides. If your sash has been double-hung, remove the ropes and weights that should fall into the pocket in the jamb lining. Once you've taken the sash off, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it manually or using a putty knife.
After the sash is cleared, you can install parting stops. These are long pieces wood that separate the two sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use a piece of scrap wood.
After removing the parting stop and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and let it dry at least a day. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new appearance.

The good news is that fixing and replacing this hardware is generally quite simple and inexpensive. If a sash is difficult to operate try spraying lubrication into the jamb channel then open it to see if that resolves the issue. If the issue persists it's likely to be due to the sash's balance. You'll need remove the window sash to get access to this part of the hardware.
Ideally, window sashes must be able to open and close with very little effort, but this can be difficult when the weights wear out or if the sash meeting rail isn't properly glazed. This problem could be caused by many factors, including an absence of maintenance or a mismatched weight rating.
If the hinge arms of a window are starting to sag, this can cause the sash window repair glass, http://Acuityplatform.com/, to slide and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To remedy the issue, make sure that the sash is aligned in the frame opening and then remove it. If the sash is secured to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Old windows, especially those in older homes, can be difficult to open and close because of sagging hinges and an overall lack of energy efficiency. Many times, a few simple fixes can allow these windows to operate smoothly once more and help homeowners save money on their energy bills.
In order to make these repairs to sash it is essential to have all of the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1). This will make it easier to put the channel in the proper position after you've finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains which hold it in place.

Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out sash weights will improve sash operation and reduce energy costs. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and attached to the movable sash by a rope. These weights function as counterbalances and allow you to open and close the window without the need for mechanical or electrical devices. The sash weights are usually disregarded or disabled by homeowners and then turned into scrap when they break; therefore you might need to find replacements.
A weight in a sash that has fallen out of the cavity is difficult to retrieve, so you will want to locate a new one that fits properly. You will also need an additional piece of string, a length the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.
Older windows made of wood are joined with mortise and tenon joints. The wood pegs that hold the parts together can be removed using pin punches and hammers. The majority of them have large diameters on one side and a smaller size on the other, which is why it is essential to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be cut with a knife and mallet.
After the sash windows repair is removed, you can take off the stops on the sash and get access to the weight pockets. This is usually done through a small hole at the bottom of each jamb. This hole is then covered by an access panel made of wood that can be ripped off so that you can see the inner workings of the frame.
Once you have the sash stopped and the access panel removed, you'll be able to take off the weight of the old sash and replace it with new. First, weigh the sash to ensure that the weights you have may not be the correct size. Once the new weight is installed, tie a string to it and thread it through the sash pulley. Then, attach the string to the boxed frame. Leave a few inches of space at the end of the string to allow for future adjustments.
Sash Cords
In the majority of double-hung windows the chain or cord is affixed to the weights. This keeps the sashes in the jamb in a balanced manner. As time passes, these cords can become damaged and make it difficult to raise the windows. A new sash cable can restore the ability to raise and lower the sash and keep it in position when it is opened.
The first step in replacing sash cords is to locate and remove the access panels within the jambs. These are usually screwed or nailed into 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 beginning any work.
After you have removed the access panel, you are able to begin to work on the sash. Take the narrow beads (also called "tie rails") out of their grooves using a chisel or flat bar. These are often wedged in or nailed but can be snipped out, so it's worth taking your time here. If the sash is still in place, break the mortise and tenon joints free with a screwdriver or hammer, then remove each wood peg. You should be able to move the sash around freely, though it may require lubrication if it feels stiff.
Take a measurement of the length of sash cord/chain required to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the cord or chain and secure it as in Step 6 above. You can use a hammer, nails, or screws. However, nails are less likely to cause damage.
Unless you've bought an item that replaces the old counterbalance system it is recommended to keep the original balancing weights in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they'll be easy to install once you have the sash open. Based on the size of your window, two or three sash weights may be needed to keep it in an open position.
