Window Sash Repairs

Regularly inspect the window sashes for signs of damage, mildew and mold. If you catch these issues early you will save money on repairs in the future.

The sash is the internal frame that is vertically moved upwards or downwards in windows that are open. This article will teach you how to do easy repairs to your sash.

Weather Stripping

Wooden window sashes are a great way to add an elegant appearance to your home. They are also durable and will last for many years when they are maintained properly. However, they may become damaged or degrade as time passes due to exposure to elements and wear and tear. However, sash repair experts can bring your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.

The first step in repair sash window damage is to fix weather stripping, which is found on both the sash and frame. If it's worn or loose, out, it can lead to drafts and other problems. To fix it, start by determining your window's brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width, so you can find the appropriate weather stripping replacement to match.


Then, remove the sash from the 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 the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. Once you've removed the sash using a utility knife, you can use it to cut off the weather stripping from the corners. Then, take it off by hand or using a putty blade.

After window repairs has been cleared, you can replace the parting stops. These are long pieces of wood that separate the two sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you could also use a piece of scrap wood.

After removing the stoppers for parting and trimming them to your desired length, 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 a day. When the putty is fully dried, you can apply an acrylic latex topcoat. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes can wear out over time and use. This could lead to the window or door that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically easy and affordable. If you are having trouble opening a sash spray some oil into the jamb channel. Then, slide the sash out to see if it resolves the problem. If not, the problem is likely with the sash balance, and you'll need to remove the sash to access this hardware.

The ideal situation is for window sashes to swing open and closed with minimal effort but this is an issue when the weights are worn or if the sash's meeting rail isn't properly coated. This issue could be caused by many factors, including an absence of maintenance or a mismatched weight rating.

If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually strike the frame in the corner that's opposite the hinge arm (Photo 1). To fix this issue, first make sure the sash fits squarely in the opening of the frame and then remove it from the window. If the sash has been screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close due to hinges that are sagging and a general lack of energy efficiency. Sometimes it is a matter of making a few minor adjustments that can make these windows operate smoothly again and save homeowners money on their energy bills.

It is important to have the tools you need before you begin. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will assist you in getting the channel back in place correctly when you're finished. Remove the sash and remove the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. Soften any hardened putty with a heat gun set to medium and fitted with a nozzle shield. Remove the old sash and keep it in a bag with a label.

Sash Weights

Sash weights are able to be replaced to improve the performance of your window sash and decrease energy costs. Sash weights consist of heavy lead or iron cylinders that are encased inside a concealed cavity, and attached by ropes to the moveable window sash. These weights provide counterbalance which allows the window to be opened and closed without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners, and are turned into scrap when they fail. Consequently you may have to search for replacements.

A sash weight that has fallen out of the cavity is difficult to get back and you'll need to locate a new one that fits correctly. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights the sash cord.

Mortise and Tenon joints are used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of them are large on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated by using a knife and mallets.

Once the sash has been removed, you can take off the sash stops and access the weight pockets. This is usually done through tiny holes at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the interior workings.

After the sash has been stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with the new. Make sure you weigh the sash prior to you begin, as the old weights could be a different size than what is needed. Once the new weight is installed, tie a string to it and then thread it through the sash pulley. Then, you can attach the string to the boxed frame. Leave a few inches protruding at the head of the string to allow for future adjustments.

Sash Cords

In the majority of old double-hung windows, a cord or chain is affixed to the weights. This helps keep the sashes of the jamb in a balanced manner. Over time, these cords can become damaged and make it impossible to raise the windows. A new sash cord will restore the ability to move the sash up and down and keep it in place when opened.

The first step to replace cords for sash is to locate and remove the access panels within the jambs. These are usually screwed or nailed into and need to be removed. It is possible to remove them using the hammer or chisel but it is always better to lay out dust sheets prior to beginning any work.

After removing the access panel, you are able to begin to work on the sash. Utilize a flat bar, or chisel to pry the small parting beads from their grooves. It's important to take your time as they're often wedged or nailed in place. If the sash remains in place, pull the mortise-and tenon joints with a hammer or screwdriver and then take out each wood peg. The sash should move around freely now, however it might require some lubrication to feel less stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then fix it as described in the previous step. You can use either nail, hammer or screws. However, nails are less likely than screws to cause damage.

If you haven't purchased an upgrade kit to replace the old counterbalance system it is recommended to keep the original weights for balancing in place. They are not expensive and are easy to install if you purchase them from salvage shops for architectural use. Based on the size of your window, one or two sash weights may be needed to keep it in an open position.
