The sash is an interior framing that can be moved vertically up or down in windows that are open. This article will show you how to do easy repairs to your sash.

Weather Stripping

Wooden window sashes are a great way to add an elegant look to your home. They are also durable and last for a long time when they are maintained properly. They can, however, become damaged or degraded with time, due to exposure and normal wear and tear. Thankfully, sash repair experts can restore your windows back to their original condition and keep them looking great for much longer than newer replacement windows.

The first step for repair sash window damage is to fix weather stripping, which is found on both the sash and frame. If it's loose or worn out, it can lead to drafts and other issues. Begin by identifying the brand of window and the date of manufacture for the glass (etched on the glass's corners or the aluminum spacers between panes). Take the sash off, and mark its width and height so you can get replacement weather stripping that matches.

Then, you can remove the sash from its holder and place it on a flat surface to allow you to see all four sides. If your sash is double-hung, you'll have to remove the weights as well as their ropes, which should have fallen into the pocket of the jamb liner. Once you've taken the sash off and the weights, use a utility knife to remove the weather stripping from the corners. Then, remove it manually or using a putty blade.

After the sash is cleared, you can replace the stoppers that separate the two sashes. These are long pieces that split 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 trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. Once the putty has fully dried it is possible to apply a topcoat of acrylic. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes can wear out over time and use. This could lead to windows or doors that is difficult to open or close. The good news is that fixing and replacing this hardware is typically quite simple and inexpensive. If a sash isn't easy to operate, try spraying some grease into the jamb channel, and then open it to see if this resolves the issue. If not, the issue is most likely due to the sash balance, and you'll need to remove the sash to access the hardware.

Ideally, window sashes must move open and shut with very little effort, but this can be an issue when the weights wear out or if the sash meeting rail isn't properly coated. This problem could be caused by various reasons such as an absence of maintenance or a mismatched weight rating.


If the hinge arms of a window begin to slide, this could cause the sash to drag and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To resolve 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 is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Next, 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 general inefficiency. In many instances, a few easy repairs can turn these windows into smooth operation and save homeowners money on energy costs.

To complete these sash repairs it is essential to have all the necessary tools lined up before you begin. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will make it easier to place the channel in the right location after you've completed. Then, remove the sash and remove the hardware including the parting beads (Photo 2) and the cords or chains that secure it. The nozzle shield of the heat gun and a medium setting will soften any hardened glue. Remove the old sash and keep it in a bag with a label.

Sash Weights

Sash weights can be changed to improve the performance of your window sash and decrease the cost of energy. Sash weights are made of iron or lead cylinders that are encased in a concealed cavity and are connected via ropes to the movable window sash. These weights function as counterbalances, allowing you to open and shut the window without having to use mechanical or electrical devices. If they fail, sashweights tend to be ignored or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve It is therefore important to locate a new one that is suitable for the. You will also need a new piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights the sash cord.

Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the parts together. The majority of these pegs have a large diameter on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be cut with a knife and mallets.

Once the sash has been removed, you can take off the sash stops and access the pockets for weights. Usually it is done 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 let you see the inner workings of the frame.

After the sash has been stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with the new. Weigh the sash first because the weights you have might not be the correct size. Once the new weight is installed, tie a string to it and thread it through the pulley for the sash. Then nail the string to the frame, but only leave a few inches of string protruding from the head for future adjustments.

Sash Cords

Most double-hung windows of the past come with a chain or cord attached to the weights which supports and keeps the sashes level within the jamb. As time passes, these cords can become damaged and render it impossible to raise windows. A new sash cord will restore the ability to move the sash up and down and keep it in place when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and will require to be removed or relocated. You may be able to use a hammer or chisel to remove them, but it's always better to lay down dust sheets prior to starting any work.

Once the access panel is removed, you can start working on the sash. Utilize a flat bar or chisel to pry the narrow partsing beads out of their grooves. It's important to take your time because they are usually placed in a wedge or nail. If the sash remains in place, break the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. It should now be possible to move the sash back and forth freely, though it might require lubrication if it feels stiff.

Measure the length of sash cord/chain required to reach the sash slot at the bottom from the pulley at the top of the jamb. Cut the cord/chain and fix it using the previous step. You can use a hammer, nails, or screws. However nails are less likely than screws to cause damage.

If you don't have an upgrade kit to replace the old counterbalance system, it's recommended to keep the original weights for balancing in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you have the sash open. Based on window repair and shape of your window you may need to use one or two sashweights to keep the sash open.
