Weather Stripping
Wooden window sashes can add an elegant appearance to your home. They are also durable and will last for many years when they are maintained properly.

Thankfully, sash repair experts can restore your windows to their original condition and keep them looking great for a longer period of time than replacement windows.
The first step in 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 could cause drafts, as well as other issues. To fix it, begin by determining the brand of your window 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 width and height so that you can locate the appropriate weather stripping replacement to match.
Then, take the sash from its holder and place it on an even surface that allows you to reach all four sides. If your sash is double-hung, you'll have to remove the weights as well as their accompanying ropes, which should have fallen into the pocket of the jamb liner. Once you've taken the sash off, use a utility knife to cut off the old weather stripping at the corners, and then remove it by hand or using a putty blade.
After the sash has been cleared it is time to replace the parting stops. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trim from the lumberyard. However, you can substitute a scrap piece of wood.
After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and let it dry at least a day. After it has fully dried, apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a modern 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 that isn't able to open or close easily. The good news is that repairing and replacing this hardware is typically very simple and cost-effective. If a sash becomes difficult to operate try spraying lubrication into the jamb channel then open it to see if this resolves the issue. If not, the problem is likely to be with the balance of the sash and you'll have to take off the sash to access this hardware.
Ideally, window sashes should be able to open and close with very little effort, but this is an issue if the weights become worn or if the sash's meeting rail isn't properly glazed. This could be caused by a variety of factors that include a lack of maintenance and a mismatched weight rating.
If the hinge arms of a window are beginning to sag, this can cause the sash to slide and eventually hit the frame in the corner that's opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash has been screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older homes, can be difficult to close and open due to hinges that are sagging and a general inefficiency. In many instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner money on energy costs.
It is crucial to have the tools you need before you start. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will help you get the channel back in the correct position after you've finished. Remove the sash and take off the hardware, including the parting beads (Photo 2) and the cords or chains which hold it in place.

Sash Weights
If your window sash repairs are to replace a broken cord or just to keep your windows functioning and functional, replacing worn-out weights for sash will improve its operation and cut down on energy costs. Sash weights are hefty lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable window sash using rope. These weights act as counterbalances and allow you to open and close the window without requiring 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.
It's difficult to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also need a new piece of string, a length the sash cord, as well as some sash pulleys to connect the new sash weights onto the sash cord.
Mortise and Tenon joints can be used to join older wood windows. The wood pegs that keep the components together can be removed with pin punches and hammers. The majority of them are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs. They can be separated by cutting the glue line using a knife, then tapping the mortised section loose with a mallet.
After the sash has been 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. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.

Once the new weight is installed, tie a string to it and then thread it through the sash pulley. Then nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustments.
Sash Cords
In the majority of old double-hung windows the chain or cord is affixed to the weights. This supports and keeps the sashes of the jamb in a balanced manner. Over time, these cords may become damaged and make it impossible to raise windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its place when opened.
The first step to replace sash cords is to find and remove the access panels within the jambs. They are usually screwed or nailed into and require removal. You might be able to use a hammer and chisel to remove them but it's best to lay down dust sheets prior to beginning any work.
Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with flat bar or chisel. It is essential to take your time, as these are often wedged or nailed in place. If the sash remains in place, break the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. The sash should be able to move around freely now, however it may require some lubrication to feel less stiff.
Measure the length of the sash chain or sash cord required to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the cord/chain and then attach it as described in Step 6 above. You can employ a hammer, screws or nails, however nails are less likely to cause damage.
