The sash is the internal frame that is vertically moved upwards or downwards in windows that are open. This article will teach you how to carry out a few simple repairs to the sash. Weather Stripping Wood window sashes give the classic look to your home and, when properly maintained, they can last for years. However, they can become damaged or degrade as time passes because of exposure to the elements and normal wear and wear and tear. Sash repair experts can restore windows to their original condition and keep them looking great longer than replacement windows. The first step to repair sash windows is to address weather stripping, which can be found on both the sash and frame. If it's damaged or worn out, it could cause drafts, as well as other issues. Begin by identifying the window brand and the manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Then, take the sash off and mark its width and height to find the appropriate weather stripping replacement to match. Then, remove the sash from its holder, and place it on a flat surface to allow you to see all four sides. If your sash was double-hung, take out the weights with their ropes that should fall into the pocket in the jamb lining. After removing the sash using the utility knife, take off the old weather stripping by hand or using the putty blade. After the sash has been cleaned, you can replace the parting stops. These are long pieces of wood that divide the two sashes. Pam prefers 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 and then apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife, and then let it dry for at least a few days. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh look. window repair near me that holds window sashes is susceptible to wear and tear from the wear and tear of use and the result could be a window or door that won't open or close easily. The good thing is that fixing and replacing this hardware is usually quite simple and inexpensive. If a sash becomes difficult to operate try spraying lubrication into the jamb channel and then open it to see if it resolves the issue. If the problem persists it's likely the sash balance. You'll need to take off the window sash to reach this hardware. Ideally, window sashes must be able to open and close with very little effort, but this can be difficult when the weights are worn or if the sash meeting rail isn't properly glazed. This problem can be caused by a number of factors, including the lack of maintenance or the wrong weight rating for the particular window sash. If the hinges on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix this issue, first make sure the sash fits squarely in the opening of the frame and then take it out of the window. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3). Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old, especially those in older homes, can be difficult to open or close. Sometimes it is a matter of making a few minor adjustments that can make these windows operate smoothly once more and save homeowners money on energy costs. To make these sash repairs it is important to have all the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will help you to position the channel in the right position after you've finished. Remove the sash and take out all the hardware including the parting beads, cords, and chains that hold the sash in place. Soften any putty that has been hardened with a heat gun set to medium and equipped with a shield for the nozzle. Remove the old sash and store it in an bag that is labeled. Sash Weights No matter if your window sash repair needs are to replace a damaged cord or just to keep the windows functional by replacing worn out sash weights will improve sash operation and reduce the energy cost. Sash weights consist of iron or lead cylindricals that are contained in a concealed cavity and are connected via a rope to the movable window sash. They provide counterbalance which allows the window to be closed and opened without using mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled by homeowners. A sash weight that has fallen out of the cavity is difficult to retrieve and you'll need to find a replacement that fits properly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys to secure the new weights to the cord. Older wood windows are joined using mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the components together. The majority of these pegs are large on one side and smaller on the other. It is important to first remove the smaller diameter sides. 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 the help of a knife, and then tapping the mortised area loose with mallets. Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. This is typically done by drilling a small hole at the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings. After the sash has been stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be different in size from what you require. Once the new weight is in place, tie a string to it and thread it through the sash pulley. Then, nail the string to your boxed frame. Leave a few inches of space at the top of the string for future adjustments. Sash Cords Most old double-hung windows include a chain or cord attached to the weights that supports and keeps the sashes level 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 up and down and will keep it in its place when it is opened. The first step to replace cords for sash is to locate and remove the access panels within the jambs. These are usually attached by nails or screws and need to be removed. It is possible to remove them with the hammer or chisel but it is always better to lay out dust sheets prior to starting any work. Once the access panel is removed, you can start working on the sash. Use a flat bar or chisel to pry the tiny parting beads from their grooves. It is essential to be patient, as these are often stuck or nailed to the floor. If the sash is still in place, remove the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then unhook the wood pegs that are on each piece. The sash should be able to move around freely now, however it may require some lubrication in order 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 on the bottom. Cut the cord/chain, and then fix it using the previous step. You can use either a hammer, nails or screws. However nails are less likely to cause damage. If you don't have a kit that replaces the old counterbalance system it's best to keep the original weights for balancing in place. They're not expensive and are easy to install if you purchase them from architectural salvage stores. Based on the size and shape of your window, you may need to use one or two sashweights in order to keep it open.
