Weather Stripping
Wood window sashes provide a classic aesthetic to your home. If properly maintained, they will last for many years.

Sash repair specialists can restore windows back to their original condition and maintain their appearance much longer than replacement windows.
The first step to sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's loose or worn out, it can cause drafts and other issues. Begin by identifying the brand of window and the glass manufacturer's date (etched on the glass's corners or the aluminum spacers between panes). Then, take the sash off and mark its width and height so that you can locate the appropriate weather stripping replacement to match.
Next, remove the sash and set it on a surface so you can access all four sides. If your sash has a double-hung, you'll need to take off the weights and their ropes which should have slipped into the intended pocket in the jamb liner. After removing the sash using the utility knife, remove the weather stripping that was left by hand or with a putty knife.
After the sash has been cleaned, you can replace parting stops. They are long pieces of wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you can also use a piece of scrap wood.
After removing the stoppers for parting and trimming them to the desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using your putty tool, and allow it to dry for at least one day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash a new 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 window or door that isn't able to open or close easily. It's good to know that replacing or repair of this hardware is typically straightforward and cost-effective. If you're having trouble opening a sash, spray some lubricant into the jamb channel. Then, you can slide the sash open to see if it resolves the issue. If not, the issue is most likely due to the sash balance, and you'll need to remove the sash in order to access the hardware.
Sashes for windows should be able to open and close without much effort. However, this could be a challenge if the weights have been worn out or the sash-to rail connecting rail isn't glazed. This problem can be due to various reasons such as an absence of maintenance or an unmatched weight rating.
If the hinges on the window begin to move, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is in the proper position within the frame's opening and take it off. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).
Due to sagging hinges, and a general lack in energy efficiency, old windows, especially those in older homes, may be difficult to open and close. Many times just a few easy fixes can make these windows operate smoothly and help homeowners save money on their energy bills.
To make these repairs to sash it is essential to have all of the tools needed before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to position the channel in the correct place when you are finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the chains or cords that hold it in place. Soften any hardened putty using the help of a heat gun set at medium and equipped with an shield to block the nozzle. Remove the old sash and store it in an labelled bag.
Sash Weights
Sash weights can be replaced to enhance the efficiency of your window sash and decrease the energy cost. Sash weights consist of heavy iron or lead cylindricals that are contained in a concealed cavity and are connected via ropes to the movable window sash. They function as counterbalances, which allows you to open and close the window without requiring mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled 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 is suitable for the. You will also need an additional piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights onto the sash cord.
Older windows made of wood are joined by mortise and tenon joints. The wood pegs holding the components together can be removed by a pin punch and hammer. The majority of them are large on one side, and smaller on the other. It is important to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated by using a knife and mallets.
After the sash is removed, you can remove the sash stop and gain access to the weight pocket. Usually it is done by drilling an opening at the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the inside workings.
After the sash has been stopped and the access panel is removed, you can remove the old weight and replace it. Make sure you weigh the sash prior to you do this, since the old weights may be different sizes than what is needed. Once the new weight is in place, tie a string to it and then thread it through the pulley of the sash. Then nail the string to the boxed frame, but only leave a few inches of string protruding from the head for future adjustment.
Sash Cords
In most old double-hung window the chain or cord is connected to the weights. This supports and keeps the sashes within the jamb level. As time passes, these cords may break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in position when it is opened.
The first step to replace sash cords is to locate and remove the access panels within the jambs. They are typically nailed or screwed in and will require to be removed or moved. It is possible to remove them with an axe or hammer, but it is always better to lay out dust sheets before starting any work.
Once the access panel is removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is important to be patient, as these are often wedged or nailed in place. If the sash remains in place, pry the mortise-and tenon joints with a hammer or screwdriver and then take out each wood peg. It should now be possible to move the sash around without difficulty, though it might require oil if it feels stiff.
With the sash open, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then secure it as in the previous step. You can do this with nail, hammer or screws. However, nails are less likely than screws to cause damage.
It's best to leave the original weights in place unless you've purchased a kit to replace the old counterbalance. It's not too expensive to purchase them from a salvage store and they will be easy to install once you have the sash unlocked. Depending on the dimensions and shape of your window you may require one or two sashweights in order to keep the sash open.
