The sash is an internal frame that can move upwards and downwards in windows that open. This article will demonstrate how to do a variety of simple sash repair.

Weather Stripping

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

The first step to repair sash windows is to address weather stripping, which can be found on both the sash as well as the frame. If it's damaged or worn out, it can lead to drafts and other issues. Begin by identifying the window brand and the manufacturer's date (etched on the corner of the glass or on the aluminum spacers between panes). Remove the sash, and mark its size and width so that you can get replacement weather stripping that matches.

Then, remove the sash and set it on a work surface so you can access all four sides. If your sash is double-hung, you'll also need to remove the weights and their accompanying ropes that should have fallen into the pocket of the jamb liner. After you've removed the sash and the weights, use a utility knife to cut away the weather stripping from the corners. Then, take it off by hand or with a putty knife.

When the sash is clean, you can replace the parting stops. These are long pieces wood that separate the two sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you could also substitute a scrap piece of wood.

After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using a putty tool and let it dry for at least a day. Once the putty has fully dried, you can apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds window sashes is prone to wearing out from time and usage and the result could be a window or door that can't be opened or closed easily. It's good to know that replacing and repair of this hardware is typically straightforward and cost-effective. If you're having trouble opening a sash, spray some lubricant into the jamb channel. Then, you can slide the sash open to see if it resolves the problem. If the issue continues it's likely the sash balance. It is necessary to take off the window sash to access the hardware.

Ideally, window sashes should move open and shut with minimal effort but this can be difficult when the weights wear out or if the sash's meeting rail isn't properly coated. This problem can be caused by a number of reasons, such as the lack of maintenance or the wrong weight rating for the particular window sash.

If the hinges on the window begin to move, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To correct the issue ensure that the sash is aligned in the frame opening and then take it off. If the sash is secured to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows, especially those in older homes, can be difficult to open and close. Many times just a few easy fixes can allow these windows to operate smoothly and save homeowners money on their energy bills.

It is important to have the tools you need before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to place the channel in the proper position after you've finished. Take the sash off and then remove all hardware including the parting beads cords, chains, and cords that hold the sash in place. Soften any hardened putty with an electric heat gun set to medium and equipped with an nozzle shield. Remove the old sash, and place it in a bag with a label.

Sash Weights

If your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional, replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are heavy lead or iron cylinders, which are enclosed inside a hidden compartment and attached to the movable window sash using rope. They are counterbalancers which allows the window to be closed and opened without the need for mechanical or electrical devices. When they fail, sashweights are usually ignored or disabled by homeowners.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits correctly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights to the sash cord.

Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to take out the wood pegs that hold the components together. The majority of these pegs have an enormous diameter on one side and a smaller one on the other, which is why it is essential to remove the smaller-diameter sides first. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using a knife, then tapping the mortised section loose using mallets.

After the sash is removed, you can take off the sash stops and gain access to the weight pockets. This is usually done via a small hole at the bottom of every jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.

When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Be sure to weigh the sash first, as the weights you have might not be of the right size. After the new weight is installed you can tie a string around it and thread it through the sash pulley. Then, attach the string to your boxed frame. Leave a few inches of space at the head of the string to allow for future adjustments.

Sash Cords

In most old double-hung window the chain or cord is connected to the weights. This keeps the sashes within the jamb balanced. As time passes, these cords may break, making it impossible to raise the window. A new sash cable can restore the ability to move and lower the sash, and keep it in position when 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 need to be removed. You could use a hammer and chisel to prise them off, but it's always better to lay down dust sheets before starting any work.

After you have removed the access panel, you are able to begin working on the sash. Utilize a flat bar, or chisel to pry the small parting beads from their grooves. It's important to be patient, as these are often placed in a wedge or nail. If the sash is still in place, pull the mortise-and tenon joints with a hammer or screwdriver and then remove each wood peg. The sash should be able move freely now, but it might require some lubrication in order to feel less stiff.

Measure the length of sash cord/chain needed to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the chain or cord, and then fix it using the step 6 above. You can either employ a hammer, screws or nails, but 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. It's not too expensive to purchase them from architectural salvage stores and they'll be easy to install once you have the sash window repair opened. Depending on the dimensions and shape of your window you may require one or two sashweights to keep it open.
