Weather Stripping
Wooden window sashes can give an elegant appearance to your home. They are also sturdy and last for a long time provided they are properly maintained. However, they can become damaged or degrade in time because of exposure to the elements and normal wear and tear. Fortunately, sash

Weather stripping is the primary aspect to consider when you are repairing windows with sash. It's located on both the frame and sash. If it's loose or worn out, it could cause drafts and other problems. Begin by identifying the brand of window and the glass manufacturer's date (etched on the corner of the glass or the aluminum spacers between panes). Remove the sash, and mark its width and height so you can find a replacement weather stripping that matches.
Then, remove the sash from the holder and place it on a flat surface to allow you to see all four sides. If your sash has a double-hung, you'll have to remove the weights as well as their accompanying ropes which should have slipped into the intended pocket in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to remove the weather stripping from the corners. Then, remove it manually or using a putty knife.
After the sash has been cleaned, you can replace the parting stops. They are long pieces of wood that divide the two sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you could also use scrap wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and let it dry for at least a day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This coating 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 the wear and tear of use, and the result can be a door or
window repair that can't be opened or closed easily. The good news is that
Repairing Glass and replacing this hardware is usually quite simple and inexpensive. If a sash becomes difficult to operate try spraying oil into the jamb channel and then open it to see if this solves the issue. If not, the problem is most likely due to the balance of the sash and you'll need to remove the sash to gain access to this hardware.
Ideally, window sashes should move open and shut with minimal effort but this can be a difficult task when the weights are worn or if the sash that joins rail isn't properly glazed. This problem can be caused by a number of factors, including lack of maintenance or by a mismatched weight rating for the specific window sash.
If the hinge arms on windows begin to slide, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is aligned 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).
Due to sagging hinges, and a general lack in energy efficiency, older windows especially in older homes, can be difficult to open and close. In many cases just a few easy fixes can help these windows function smoothly once more and help homeowners save money on energy bills.
It is important to have the tools you require before you start. Mark the hinge channel location on the frame (Photo 1) using pencil. This will allow you to place the channel in the proper location after you've completed. Then, remove the sash and take off the hardware including the parting beads (Photo 2) and the chains or cords that hold it in place. The nozzle shield of the heat gun and a medium setting will soften any putty that has been hardened. Remove the old sash, and put it in a labelled bag.
Sash Weights
Whether your window sash
doors repairs are to replace a damaged cord or simply to keep the windows functional, replacing worn out weights for sash will improve its operation and help reduce the energy cost. Sash weights are made of heavy iron or lead cylinders that are enclosed in a hidden cavity and attached by a rope to the movable window sash. These weights provide counterbalance, allowing the window to be opened and closed without the use of electrical or mechanical devices. If they fail, sashweights are often neglected or not used by homeowners.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll need to find one that fits correctly. You will also require a new piece of string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.
Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of these pegs are big on one side, but smaller on the other. It is crucial to first remove the smaller diameter sides. Later sashes used glue instead of pins. They can be cut with a knife and mallets.
After the sash is removed then you can take out the sash stop and gain access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. This hole is covered by an access panel made of wood that can be ripped off so that you can observe the inner workings of the frame.
Once the sash is stopped and the access panel is removed, you are able to remove the old weight and replace it. Be sure to weigh the sash before you do this, since the old weights may be different in size from the one you need. Once the new weight has been installed, run the string through the sash pulling mechanism. Then, attach the string to your boxed frame. Leave a few inches of space at the head of the string to allow future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This supports and keeps the sashes within the jamb balanced. As time passes, these cords may break, making it impossible to raise the window. A new sash cable will restore the ability to move and lower the sash, and ensure it stays in place when opened.
To replace sash cords, the first step is to remove the access panels from the jambs. These are usually screwed or nailed in and need to be removed. It may be possible to take them out using an axe or hammer, however, it is best to lay out dust sheets before starting any work.
After removing the access panel, you are able to begin working on the sash. Use a flat bar or chisel to pry the small partsing beads out of their grooves. It is important to take your time because they are usually stuck or nailed to the floor. If the sash is still in place, break the mortise and the tenon joints by using pin punch and hammer or screwdriver, and then take out the wood pegs on each component. The sash should be able move freely now, but it might require some lubrication to make it feel less stiff.
Determine the length of sash chain/sash cord needed to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the cord or chain and attach it in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.
It's best to leave the original weights in place unless you've purchased a kit to replace the counterbalance. They are not expensive and simple to install if you purchase them from salvage shops for architectural use. Based on the size and shape of your window, you may need to use one or two sashweights to keep it open.
