Window sashes must be checked regularly for mold, mildew, and damage. You can avoid future repair costs by catching these issues in the early stages before they get out of hand.

Weather Stripping
Wooden window sashes can give a classic look to your home. They are also sturdy and can last many years provided they are properly maintained. However, they may become damaged or degraded as time passes due to exposure to elements and wear and tear. Sash repair specialists can restore windows back to their original condition and keep them looking great much longer than replacement windows.
The first step in repair sash windows is to address weather stripping, which is found on both the sash as well as the frame. It could cause drafts if damaged or is loose. To fix it, start by finding your window brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, and mark its width and height so you can find a new weather stripping that is compatible with the original.
Then, remove the sash from the holder and place it on an even surface that allows you to reach all four sides. If your sash was double-hung, you must remove the ropes and weights that should be buried within the jamb lining. After removing the sash using the utility knife, you can remove the old weather stripping by hand or using the putty blade.
Once the sash is clear it is time to replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also use for a scrap piece of lumber.
After removing the parting stops and trimming them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for at least a few days. Once the putty has fully cure, you can apply an acrylic latex topcoat. This will protect the putty, and give your sash an updated appearance.
Sash Hardware
The hardware that holds the windows sashes can become worn out over time and use. This could result in windows or doors that is difficult to open or close. The good thing is that fixing and replacing this hardware is generally relatively easy and affordable. 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 issue. If the issue persists, it is most likely that the sash balance is off. You'll need to remove the window sash to reach this hardware.
Ideally, window sashes should move open and shut with very little effort, however, this can be difficult when the weights wear out or if the sash's meeting rail isn't properly glazed. This problem can be due to a variety of factors such as the lack of maintenance or a mismatched weight rating.
If the hinges on the window begin to move, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To correct the issue ensure that the sash is in the proper position within the frame opening, and then take it off. If the sash has been fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Old windows, especially those in older homes, may be difficult to open and close due to hinges that are sagging and general inefficiency. Sometimes it is a matter of making a few minor adjustments that can help these windows function smoothly once more and save homeowners money on energy bills.
To make these repairs to sash it is essential to have all of the necessary tools lined up before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will allow you to get the channel back in place correctly when you're finished. Take the sash off and then remove all hardware including the parting beads, cords, and chains that keep the sash in place. Soften any putty that has been hardened with an electric heat gun set to medium and fitted with a nozzle shield. Remove the old sash and store it in an bag with a label.
Sash Weights
Sash weights can be replaced to improve the operation of your window sash, and also reduce the energy cost. Sash weights consist of iron or lead cylindricals that are contained in a hidden cavity and attached by ropes to the moveable window sash. These weights act as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights are usually left unnoticed or disabled by homeowners.
It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits properly. You will also need a new piece of string, a length of the sash cord, as well as some 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. upvc window repairs that keep the parts together can be removed with pin punches and hammers. The majority of these pegs are large on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Later sashes used glue instead of pins. They can be separated with a knife and a mallet.
Once the sash is freed and removed, you can take off the sash stop and access the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. This hole is then covered by an access panel made of wood that can be cut off to allow you to view the inside of the frame.
After the sash has been stopped and the access panel has been removed, you can remove the weight that was previously installed and replace it. Weigh the sash first to ensure that the weights you have 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 pulley for the sash. Then attach the string to the frame, but only leave a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In most old double-hung window the chain or cord is attached to the weights. This keeps the sashes in the jamb level. Over time, these cords can get damaged and render it impossible to raise windows. A new sash cord can restore the ability to move the sash up and down and will keep it in its place when opened.
The first step to replace cords for sash is to locate and remove the access panels within the jambs. These are usually screwed or nailed into and must be removed. You could employ a hammer and chisel for removing them however, it is always best to lay down dust sheets before starting any work.
After the access panel has been removed, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves using flat bar or chisel. It is essential to take your time because they are usually wedged or nailed in place. If the sash is in place, break the mortise and tenon joints using the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to each component. The sash should be able to move around freely now, however it may require some lubrication in order to feel less stiff.
Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the chain or cord and secure it in the previous step. You can do this with nail, hammer or screws. However nails are less likely than screws to cause damage.
If you haven't purchased an item that replaces the counterbalance system that was in place before, it's recommended to keep the original balancing weights in place. They're not costly and easy to install if purchased them from salvage shops for architectural use. Depending on the size of your window one or two sashweights could be needed to keep it open.
