The sash is an interior framing that can be moved vertically upwards or downwards in windows that open. This article will teach you how to perform 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 provided they are properly maintained. However, they may become damaged or deteriorate in time because of exposure to the elements and wear and tear. Sash repair specialists can restore windows to their original condition and maintain their appearance much longer than replacement windows.

The first step for repair sash window damage is to fix weather stripping, which is found on both the sash and frame. It could cause drafts if worn or loose. Begin by identifying the window brand and the glass manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Then, take the sash off and mark its width and height so that you can locate replacement weather stripping to match.

Then, take the sash from its holder, and place it on flat surfaces to allow you to access all four sides. If your sash was double-hung, remove the weights with their ropes that should have fallen into the pocket in the jamb lining. Once you've taken the sash off and the weights, use a utility knife to cut away the weather stripping from the corners, and then remove it manually or using a putty knife.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the 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 scrap wood.

After removing the parting stop and trimming it to length after which, 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 day. After the putty has completely cure and dried, you can apply a topcoat of acrylic latex. This will help protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from age and use, and the result can be a window or door that won't open or close easily. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If you're having trouble opening a sash, spray some grease into the jamb channel. Then slide window repair service out to see if that fixes the issue. If not, the problem is most likely due to the balance of the sash and you'll need to take out the sash to gain access to the hardware.

Window sashes need to open and close without much effort. However, this could be difficult if the weights are worn out or the sash-to rail meeting rail is not properly coated. This problem can be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for a particular window sash.


If the hinges on the window begin to move, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash is fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Because of sagging hinges and a general deficiency in energy efficiency, older windows, especially those in older houses, could be difficult to open and close. In most cases, a few simple repairs can turn these windows into smooth operation again and save the homeowner money on energy costs.

To make these repairs to sash it is essential to have all the necessary tools in place before you begin. Mark the location of the hinge channel on the frame (Photo 1) with a pencil. This will allow you to get the channel back into position correctly after you've completed. Then, remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. Soften any hardened putty with an electric heat gun set to medium and equipped with a shield to block the nozzle. Take off the old sash and store it in an labelled bag.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and decrease energy costs. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable window sash using rope. These weights act as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.

It is difficult to recover an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also require a new piece string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that keep the components together can be removed using pin punches and hammers. Most of them have large diameters on one side and a smaller size on the other, so it is crucial to take out the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be separated with a knife and mallet.

After the sash is released, you can remove the sash stops and gain access to the weight pockets. This is usually done through a small hole at the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inner workings.

After you have the sash stopped and the access panel removed, you will be able to take off the old sash weight and replace it with the new. Be sure to weigh the sash prior to you do this, as the old weights could be different in size from what is needed. Once the new weight is installed, you can thread a string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches of space at the top of the string to allow future adjustments.

Sash Cords

The majority of double-hung windows with a history come with a chain or cord connected to the weights that supports and keeps the sashes in balance within the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash up and down and will keep it in its position when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically screwed or nailed in and must be removed. It is possible to take them out using the hammer or chisel however, it is best to lay out dust sheets prior to beginning any work.

After you have removed the access panel, you can begin to work on the sash. Utilize a flat bar or chisel, to pry the small partsing beads out of their grooves. It is important to take your time as they're often stuck or nailed to the floor. If the sash is still in place, pull the mortise-and tenon joints with a hammer or screwdriver and then take out each wood peg. You should now be able to move the sash around without difficulty, though it might require oil if it feels stiff.

Take a measurement of the length of sash cord/chain needed to reach the sash slot at the bottom, and the pulley on the top of the jamb. Cut the chain or cord and then fix it using the previous step. You can either employ a hammer and screws or nails, but nails are less likely to cause damage.

If you don't have a kit that replaces the counterbalance system that was in place before, it's best to keep the original weights for balancing in place. They're not costly and are easy to install if you buy them from salvage shops for architectural use. Depending on the size of your window, two or three sash weights could be needed to keep the sash in an open position.
