If your sash has been double-hung, remove the ropes and weights that should fall into the pocket inside the jamb lining. After removing the sash with the utility knife, remove the old weather stripping by hand or with a putty knife. After the sash has been cleared, you can replace the 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. But, you can also use a scrap piece of wood. After removing the stoppers for parting and trimming them to your desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least a day. After the putty has completely cure and dried, you can apply an acrylic latex topcoat.

Ideally, window sashes must be able to open and close with minimal effort but this is an issue if the weights become worn or if the sash's meeting rail isn't properly glazed. This issue could be caused by a variety of factors, including the lack of maintenance or an unmatched weight rating. If window repair of a window are beginning to sag, this can cause the sash to drag and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To remedy the issue make sure the sash is centered in the frame opening and then remove it. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3). Because of sagging hinges and a general lack of energy efficiency, windows that are old especially in older homes, may be difficult to open and close. Sometimes, a few simple fixes can allow these windows to operate smoothly and save homeowners money on energy bills. In order to make these repairs to sash it is essential 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.

Sash Weights No matter if your window sash repair needs are to replace a damaged cord or simply to keep the windows functional by replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are heavy lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable the sash with rope. These weights function as counterbalances, allowing you to open and shut the window without having to use mechanical or electrical devices. If they fail, sashweights tend to be ignored or disabled by homeowners. It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also require a new piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord. Mortise and Tenon joints can be used to join windows made of older wood. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. Most of them have a large diameter on one side and a smaller diameter on the other side, so it is essential to remove the small-diameter sides first. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using an instrument, and then tapping the mortised area loose using mallets. Once the sash has been removed, you can take off the sash stops and gain access to the pockets for weights. This is typically done by drilling a small hole in the bottom of each jamb. This hole is then covered by a wooden access panel that can be ripped off to let you view the inside of the frame. Once the sash is stopped and the access panel is removed, you are able to remove the old weight and replace it. Weigh the sash first to ensure that the weights you have might not be the right size. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then attach the string to the frame, but only leave a few inches of string hanging from the head for future adjustment. Sash Cords The majority of double-hung windows with a history include a chain or cord attached to the weights which helps keep the sashes level in the jamb. Over time, these cords may become damaged and make it impossible to raise the windows. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its position when it is opened. The first step to replace sash cords is to find and remove the access panels in the jambs. They are usually screwed or nailed into and must be removed. You may be able to employ a hammer and chisel for removing them but it's best 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 pry the tiny partsing beads out of their grooves. It is important to be patient because they are usually placed in a wedge or nail. If the sash is in place, remove the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs that are on each piece. You should be able to move the sash back and forth freely, although it might require oiling if it seems stiff. Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom from the pulley at the top of the jamb. Cut the chain or cord, and then secure it in Step 6 above. You can employ a hammer and screws or nails, however nails are less likely to cause damage. Unless you've bought a kit that replaces the counterbalance system that was in place before, it's recommended to keep the original balancing weights in place. It's not too expensive to purchase them from a salvage store and they'll be simple to install once you've got the sash opened. Based on the size and shape of your window, you may need to use one or two sashweights to keep it open.
