Window Sash Repairs

Check the windows sashes regularly for damage, mildew, and mold. By catching these problems early you will save money on future repairs.

The sash is an internal frame that can move upwards and downwards in windows that are open. This article will teach you how to do simple repairs to sash.

Weather Stripping

Wood window sashes add a classic aesthetic to your home. When properly maintained, they will last for a long time. They can, however, be damaged or degraded over time due to exposure or normal wear. Sash repair experts can restore windows to their original condition and maintain their appearance longer than replacement windows.

The first step in repair sash windows is to address weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it can lead to drafts and other issues. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, and mark its size and width so that you can find a replacement weather stripping that matches.

Then, take it off and set it on a work surface so that you can reach all four sides. If the sash is double-hung, you'll need to take off the weights and their ropes, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash with the utility knife, take off the weather stripping from the old sash by hand or with the putty blade.

Once the sash has been cleaned, you can replace parting stops. These are long pieces that separate the sashes. Pam prefers the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also substitute for a scrap piece of lumber.

After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a day. After it has fully dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that holds the window sashes may wear out over time and with use. This can result in windows or doors that is difficult to open or close. It's good to know that replacing or repairing this hardware is often simple and inexpensive. If you're having trouble opening the sash, spray some oil into the jamb channel. Then, you can slide the sash up and open to see if that fixes the problem. If not, the problem is most likely due to the sash balance, and you'll need to take out the sash to gain access to this hardware.

Ideally, window sashes must swing open and closed without effort, but this is a difficult task if the weights become worn or if the sash meeting rail isn't properly coated. This can be due to various reasons that include an absence of maintenance or a mismatched weight rating.

If the hinge arms on windows begin to slide, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To fix the problem, make sure that the sash is aligned in the frame opening, and then take it off. If the sash is screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Old windows, particularly those in older homes, may be difficult to open and close due to hinges that are sagging and a general inefficiency. In many instances, a few minor repairs can turn these windows into smooth operators and save homeowners money on energy costs.

To make these sash repairs, it's important to have all of the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will assist you in getting the channel back on the correct position after you've finished. Remove the sash and remove the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. A hot gun with nozzle shield and a medium setting will soften any hardened glue. Remove the old sash, and put it in a bag that is labeled.

Sash Weights

Sash weights can be changed to improve the operation of your window sash and reduce the cost of energy. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and connected to the movable window sash using rope. They provide counterbalance, allowing the window to be shut and opened without using 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 get back, so you will want to locate a new one that is suitable for the. 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 older wood windows. Pin punch and hammer can be used to remove the wood pegs that hold the parts together. The majority of them are large on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting the glue line with an instrument, and then tapping the mortised part loose with a mallet.

Once window repairs has been removed, you can take off the sash stops and gain access to the weight pockets. 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 which can be removed to let you observe the inner workings of the frame.


Once 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 begin, as the weights that were previously used may be different sizes than the one you need. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then, you can nail the string to the boxed frame, but only leave a few inches of string sticking out from the head for future adjustment.

Sash Cords

In the majority of double-hung windows the chain or cord is attached to the weights. This supports and keeps the sashes in the jamb level. As time passes, these cords may break, making it difficult to raise the window. A new sash cord will give you the ability to move the sash up and down and will keep it in its place when opened.

The first step in replacing cords for sash is to locate and remove the access panels in the jambs. They are typically screwed or nailed in and require removal. You may be able to use a hammer and chisel to remove them however, it is always best to lay down dust sheets prior to commencing any work.

After you have removed the access panel, you can begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It is essential to be patient, as these are often stuck or nailed to the floor. If the sash is still in place, pull the mortise-and tenon joints using a hammer or screwdriver and then take out each wood peg. It should now be possible to move the sash around freely, though it will probably need some lubrication if it feels stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley on the top of the jamb to the sash slot in the bottom. Cut the chain or cord and fix it as described in Step 6 above. You can use nail, hammer or screws. However nails are less likely to cause damage.

It is recommended to keep the original weights if you've purchased a kit to replace the counterbalance that was previously installed. It's cheap to purchase these from salvage shops for architectural purposes and they'll be simple to install once you've got the sash opened. Based on the size of your window two or three sash weights could be needed to keep it open.
