Weather Stripping
Wood window sashes provide the classic look to your home. When properly maintained, can last for a long time. However, they can get damaged or deteriorated over time, due to exposure and normal wear and tear.

Weather stripping is the first aspect to consider when you are repairing windows that have sash. It is located on both the frame and sash. If it's damaged or worn out, it can cause drafts, as well as other issues. To fix it, begin by finding your window brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width, so you can find the appropriate weather stripping replacement to match.
Then, take it off and place it on a table so that you can reach all four sides. If the sash is double-hung, you'll have to remove the weights as well as their accompanying ropes, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, you can remove the weather stripping that was left 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 replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you could also use a piece of scrap wood.
After removing the stopper 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 then let it dry for at least a few days. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that holds window sashes is prone to wearing out from age and use and the result could be a door or window that can't be opened or closed easily. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If a sash isn't easy to operate, try spraying some oil into the jamb channel and then open it to see if this resolves the issue. If the issue persists it's most likely that the sash balance is off. You'll need to remove the window sash in order to get access to this part of the hardware.
The ideal situation is for window sashes to be able to open and close with minimal effort however, this can be difficult when the weights wear out or if the sash that joins rail isn't properly coated. This issue can be caused by a variety of things, such as lack of maintenance or by a mismatched weight rating for a particular sash.
If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to slide and eventually land on the frame in the corner directly opposite the hinge arm (Photo 1). To fix the problem ensure that the sash is in the proper position within the frame's opening and take it off. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In most cases, a few simple repairs can turn these windows into smooth operators again and save the homeowner money on energy bills.
It is important to have the tools needed before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will allow you to get the channel back in the correct position after you've finished. Remove the sash and then remove all hardware, including the parting beads cords, chains, and cords that help to hold the sash. Heat gun with nozzle shield and a medium setting will soften any putty that has been hardened. Remove the old sash and store it in an labelled bag.
Sash Weights
Sash weights can be changed to improve the performance of your window sash and decrease energy costs. Sash weights are made of heavy iron or lead cylindricals that are contained in a hidden cavity and attached by ropes to the movable window sash. These weights act as counterbalances, which allows you to open and shut the window without the need for mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and turned into scrap when they break; therefore you may have to locate replacements.
A sash weight that has fallen out of the cavity is difficult to recover and you'll need to find a new one that is suitable for the. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord.
Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that hold the components together can be removed using the use of a pin punch and hammer. Most of them have a large diameter on one side and a smaller one on the other side, so it is essential to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be cut by using a knife or mallet.
Once the sash has been released, you can remove sash stops and access the weight pockets. Usually it is done by drilling a hole near the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inside workings.
After 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. First, weigh the sash, as the weights you've got may not be the correct size. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then, you can nail the string to the boxed frame, but leave a few inches of string protruding from the head for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord connected to the weights that helps keep the sashes balanced in the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in position when it is opened.
The first step to replace sash cords is to locate and take out the access panels located in the jambs. They are usually fixed or screwed in and must be removed or relocated. It may be possible to take them out using a hammer or chisel, but it is always better to lay out dust sheets before starting any work.
After you have removed the access panel, you are able to begin to work on the sash. Use double glazed window repairs or chisel to pull the tiny parting beads from their grooves. They are usually wedged in or nailed, but they can be snipped out and it's worth your time. If the sash remains in place, pry out the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs on each component. You should be able to move the sash around freely, though it might require oiling if it seems stiff.
With the sash open With the sash in an open position, measure the sash chain or cord to reach from the pulley in the top of the jamb to the sash slot at the bottom. Cut the cord or chain and then attach it as described in Step 6 above. You can either use a hammer and screws or nails, but nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system it's recommended to keep the original balancing weights in place. They're not costly and simple to install if purchased them from architectural salvage stores. Based on the size and shape of your window you may require one or two sashweights to keep it open.
