The sash is an interior framing that can be moved vertically either up or down in windows that open. This article will teach you how to carry out a few simple sash repair.

Weather Stripping

Wood window sashes give a classic aesthetic to your home and, when properly maintained, they will last for many years. However, they may become damaged or degrade as time passes because of exposure to the elements and wear and wear and tear. Sash repair experts can restore windows to their original state and maintain their appearance longer than replacement windows.

The first step for repair sash window damage is to fix weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it can cause drafts, as well as other issues. To fix it, begin by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or Window Sash Repairs on the aluminum spacer between panes). Then, take the sash off and mark its width and height so that you can locate new weather stripping that matches.

Next, remove the sash and set it on a table to allow access to all four sides. If the sash is double-hung, you'll have to remove the weights as well as their ropes which should have slipped into the intended pocket in the jamb liner. After removing the sash with the utility knife, take off the old weather stripping by hand or with the putty blade.

When the sash is clean, you can replace the parting stops. These are long pieces that split the sashes. Pam likes 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 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 with your putty knife, then let it dry for at least a day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear due to age and use and the result could be a door or window that can't be opened or closed easily. It's a good idea to know that replacing and repairing this hardware is often easy and affordable. If you are having trouble opening the sash, spray some lubricant into the jamb channel. Then, you can slide the sash out to see if that fixes the problem. If not, the issue is likely to be with the balance of the sash and you'll have to take off the sash to gain access to this hardware.

Ideally, window sashes should be able to open and close with very little effort, but this is an issue when the weights are worn or if the sash that joins rail isn't properly coated. This problem can be due to a variety of factors, including an absence of maintenance or a mismatched weight rating.

If the hinge arms of a window are beginning to sag, this can cause the sash's to drag and eventually land on the frame in the corner directly opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general deficiency in energy efficiency, windows that are old particularly those in older homes, may be difficult to open and close. In many cases, a few simple repairs can transform these windows into smooth operation for the first time and save the homeowner cash on energy costs.

It is important to have the tools you need before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will make it easier to position the channel in the right place when you are finished. Remove the sash and remove the hardware including the parting beads (Photo 2) and the chains or cords that secure it. Soften any hardened putty using the help of a heat gun set at medium and fitted with a shield for the nozzle. Remove the old sash, and put it in a bag labeled.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash, and also reduce the energy cost. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and connected to the movable window sash using a rope. These weights function as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they fail; therefore you may have to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to get back, so you will want to find a replacement that fits correctly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights onto the sash cord.

Older windows made of wood are joined using mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of these pegs are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line with an instrument, and then tapping the mortised part loose using a mallet.

Once the sash is freed and removed, you can take off the sash stop and access the weight pocket. This is usually done via tiny holes at the bottom of each jamb. This hole is covered by an access panel made of wood that can be ripped off so that you can see the inner workings of the frame.

When the sash has been shut off and the access panel has been removed, you can take off the weight that was previously installed and replace it. Be sure to weigh the sash before you do this, as the weights that were previously used may be different in size from the one you need. After the new weight is in place you can tie a string around it and then thread it through the pulley of the sash. Then attach the string to the frame, but only leave a few inches of string hanging from the head for future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain connected to the weights that helps keep the sashes in balance within the jamb. As time passes, these cords may break, making it impossible to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and keep it in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually screwed or nailed into and need to be removed. You may be able to use a hammer or chisel to prise them off, but it's always better to lay down dust sheets prior to beginning any work.

After the access panel has been removed, you can start working on the sash. Utilize a flat bar or chisel to pull the small parting beads out of their grooves. It is essential to be patient as they're often stuck or nailed to the floor. If the sash remains in place, break the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, and then take out the wood pegs on each piece. The sash should move freely now, but it may 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 at the bottom. Cut the chain or cord and fix it as described in the previous step. You can employ a hammer and nail or screws, but nails are less likely to cause damage.

It is recommended to keep the original weights in place unless you've purchased a kit to replace the counterbalance that was previously installed. It's not expensive to buy them from architectural salvage stores and they'll be easy to install once you've got the sash opened. Based on the size of your window one or two sash weights might be required to keep it open.
