Weather Stripping

Wood window sashes provide a classic aesthetic to your home. When properly maintained, they will last for many years. They can, however, become damaged or degraded with time due to exposure or normal wear and tear. Sash repair experts can restore windows to their original condition and keep them looking great much longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if damaged or is loose. To fix it, begin by determining the brand of your window and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off and mark its size and width so that you can get new weather stripping that is compatible with the original.

Then, take it off and place it on a work surface so that you can reach all four sides. If your sash was double-hung, remove the weights using their ropes that should fall into the pocket in the jamb lining. After you have removed the sash using the utility knife, take off the weather stripping from the old sash by hand or using the putty blade.

When the sash is clean it is time to 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 scrap wood.

After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for at least a few days. When the putty is fully cure, you can apply an acrylic latex topcoat. This will help protect the putty and give your sash a modern appearance.

Sash Hardware

The hardware that supports the window sashes can wear out with time and use. This could lead to the window or door that is difficult to open or close. The good thing is that fixing and replacing this hardware is typically quite simple and inexpensive. If a sash isn't easy to operate try spraying grease into the jamb channel then slide it open to see if that fixes the problem. If not, the issue is likely to be with the sash balance and you'll have to take off the sash to gain access to the hardware.

Sashes for windows should be able to be able to open and close with minimal effort. However, this could be difficult if weights are worn out or the sash-to-rail meeting rail is not properly covered with. This problem can be due to a variety of factors, including the lack of maintenance or a mismatched weight rating.

If the hinge arms on windows begin to slide, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To resolve 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 screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).

Windows that are old, especially in older houses, can be difficult to close and open due to sagging hinges and an overall lack of energy efficiency. In many cases, a few simple repairs can transform these windows into smooth operation and save homeowners money on energy bills.

It is crucial to have the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will make it easier to put the channel in the right place when you are finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords that hold it in place. Soften any putty that has been hardened with a heat gun set to medium and fitted with a shield for the nozzle. Remove the old sash and store it in an bag that is labeled.

Sash Weights

Sash weights can be replaced to enhance the efficiency of your window sash and decrease the cost of energy. Sash weights are heavy lead or iron cylinders, which are enclosed in a hidden cavity and linked to the moveable window sash using rope. These weights provide counterbalance, allowing the window repair to be closed and opened without the need for mechanical or electrical devices. When they fail, sashweights are often left unnoticed or disabled by homeowners.

A weight from a sash that fell out of the cavity is difficult to recover and you'll need to locate a new one that is suitable for the. You will also require a new piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that keep the parts together can be removed using pin punches and hammers. 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 and can be separated by cutting the glue line using a knife, then tapping the mortised area loose with mallets.

Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.

After you have the sash stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with new. Be sure to weigh the sash before you do this, as the old weights could be a different size than what is needed. Once the new weight has been installed, you can thread the string through the sash pulling mechanism. Then nail the string to the frame, leaving a few inches of string hanging from the head to allow for future adjustments.

Sash Cords

In the majority of double-hung windows, a chain or cord is connected to the weights. This helps keep the sashes in the jamb balanced. Over time, these cords could 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 keep it in place when it is 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 must be removed. You might be able to use a hammer or chisel for removing them, but it's always better to lay down dust sheets before commencing any work.

After the access panel has been removed, you can start working on the sash. Utilize a flat bar or chisel to pry the tiny partsing beads out of their grooves. It is essential to be patient because they are usually stuck or nailed to the floor. If the sash is in place, pry out the mortise and tenon joints with pin punch and hammer or screwdriver, then remove the wood pegs on each component. It should now be possible to move the sash back and forth freely, though it might require oiling if it seems stiff.

Determine the length of the sash chain or sash cord needed to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut the chain or cord and secure it as in Step 6 above. You can do this with 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's best to keep the original balancing weights in place. It's not too expensive to purchase them from a salvage store and they will be easy to install once you've got the sash opened. Depending on the size of your window, two or three sash weights could be needed to keep it open.
