The sash is an interior frame that is able to move up and down vertically in windows that are open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wood window sashes give a classic aesthetic to your home. When properly maintained, they can last for many years. They can, however, get damaged or deteriorated over time due to exposure or normal wear. Thankfully, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for longer than replacement windows.

The first step to repair sash window damage is to fix weather stripping. It's found on both the sash and frame. If it's loose or worn out, it could cause drafts, as well as other issues. Start by identifying the brand of window and the manufacturer's date (etched on the glass's corners or on the aluminum spacers between panes). Take the sash off 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 surface so you can access all four sides. If the sash is double-hung, you must remove the ropes and weights that should have fallen into the pocket within the jamb lining. After you've removed the sash using a utility knife, you can use it to cut off the weather stripping that was formerly in place at the corners. Then, remove it manually or with a putty knife.

After the sash is cleared, you can replace parting stops. These are long pieces that split the 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 scrap wood.

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

Sash Hardware

The hardware that supports the window sashes can wear out over time and with use. This can result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is generally very simple and cost-effective. If a sash is difficult to operate you can try spraying some oil into the jamb channel and then open it to see if that resolves the issue. If not, the issue is likely with the balance of the sash and you'll need to remove the sash in order to access the hardware.

Ideally, window sashes should be able to open and close with very little effort, however, this can be difficult when the weights are worn or if the sash that joins rail isn't properly coated. This problem can be due to many factors such as the lack of maintenance or a mismatched weight rating.

If the hinge arms of a window begin to sag, this can cause the sash's to drag and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash is screwed to the hinge arm, you'll have to remove 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 especially in older homes, may be difficult to open or close. In most instances, a few minor repairs can turn these windows into smooth operators again and save the homeowner cash on energy costs.

It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will allow you to place the channel in the right location after you've completed. Then, 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 using the help of a heat gun set at medium and equipped with an shield to block the nozzle. Take off the old sash and put it in a bag labeled.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or just to keep the windows functional, replacing worn out sash weights will improve sash operation and help reduce the energy cost. Sash weights are composed of iron or lead cylinders that are enclosed in a concealed cavity and are connected via a rope to the movable window sash. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights are usually left unnoticed or disabled by homeowners.

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

Older wood windows are joined with mortise and tenon joints. 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, and smaller on the other. It is essential to first remove the smaller diameter sides. 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 pockets for weights. Usually, this is done through a hole near the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the interior workings.

Once you have the sash stopped and the access panel removed, you'll be able to take off the weight of the old sash and replace it with new. Make sure you weigh the sash prior to you begin, as the old weights may be a different size than what is needed. After the new weight is installed then tie a string to it and thread it through the pulley for the sash. Then, nail the string to your boxed frame. Leave a few inches of space at the end of the string for future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain attached 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 give you the ability to move the sash up and down and hold it in 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. You might be able to employ a hammer and chisel to prise them off, but it's always better to lay down dust sheets prior to beginning any work.

Once the access panel is removed, you can begin working on the sash. Utilize a flat bar, or chisel, to pry the narrow parting beads out of their grooves. It is important to be patient, as these are often wedged or nailed in place. If the sash is still in place, pull the mortise-and tenon joints using a hammer or Window Doctor screwdriver, then remove each wood peg. It should now be possible to move the sash around freely, although it may require lubrication if it feels stiff.

With the sash open Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord or chain and fix it as described in the previous step. You can do this with nail, hammer or screws. However nails are less likely to cause damage.

If you haven't purchased an upgrade kit to replace the counterbalance system that was in place before, it's best to keep the original balancing weights in place. It's cheap to purchase them from architectural salvage stores and they'll be simple to install once you have the sash unlocked. Based on the size of your Window Doctor two or three sash weights could be needed to keep it in an open position.
