Window Sash Repairs Check the windows sashes regularly for damage, mildew, and mold. If you catch these issues early, you can save money on future repairs. The sash is an interior frame that can move vertically up and down in windows that open. This article will teach you how to perform easy repairs to your sash. Weather Stripping Wooden window sashes can add an elegant look to your home. They are also sturdy and last for a long time if they are properly maintained. However, they can be damaged or deteriorate in time due to exposure to elements and normal wear and wear and tear. Sash repair experts can restore windows to their original condition and maintain their beauty longer than replacement windows. Weather stripping is the most important thing to address when repairing windows that have sash. It's located on both the frame and sash. It can cause drafts if damaged or is loose. To fix it, begin by finding your window brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off and mark its width and height so that you can purchase replacement weather stripping that matches. Then, remove the sash and place it on a work surface so you can access all four sides. If your sash has a double-hung, you'll have to remove the weights and their ropes that should have fallen into the intended pocket in the jamb liner. After you have removed the sash using the utility knife, take off the old weather stripping by hand or using the putty blade. After the sash has been cleared, you can replace the parting stops. These are long pieces wood that are used to separate the two sashes. Pam prefers standard ½-inch by ¾-inch window trimming from the lumberyard. However, you could also substitute a scrap piece of wood. After removing the parting stop and trimming it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least one day. After the putty has completely dried it is possible to apply a topcoat of acrylic. This will protect the putty, and give your sash a modern appearance. Sash Hardware The hardware that supports window sashes may wear out with time and use. This can result in windows or doors that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often easy and affordable. If a sash becomes difficult to operate try spraying lubrication into the jamb channel and then slide it open to see if this fixes the problem. If not, the problem is most likely due to the balance of the sash and you'll need to remove the sash in order to access the hardware. Window sashes need to open and close with little effort. However, this could be a challenge if the weights have been worn out or the sash-to rail connecting rail isn't coated. This issue can be due to many factors, including a lack of maintenance and a mismatched weight rating. If the hinge arms of a window are beginning to sag, this can cause the sash to drag and eventually strike the frame in the corner in the opposite direction of the hinge arm (Photo 1). To fix 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 has been screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash (Photo 3). Old windows, particularly those in older houses, can be difficult to open and close due to hinges that are sagging and general inefficiency. Many times just a few easy fixes can make these windows operate smoothly once more and save homeowners money on energy bills. It is essential to have the tools you need before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will allow you to position the channel in the correct position after you've finished. Then, remove the sash and take off the hardware including the beads that separate (Photo 2) and the chains or cords which hold it in place. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with an shield to block the nozzle. Remove the old sash and keep it in a bag labeled. Sash Weights Sash weights are able to 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 the sash with rope. They function as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners. A weight from a sash that fell out of the cavity is difficult to get back, so you will want to find a replacement that fits correctly. You will also need a new piece of string, a length of sash cord, and a few 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 hold the parts together can be removed by pin punches and hammers. The majority of these pegs are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallet. Once the sash has been released, you can remove sash stops and access the pockets for weights. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings. Once you have the sash stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with the new. Weigh the sash first, as the weights you've got may not be of the right size. After the new weight is installed you can tie a string around it and thread it through the pulley for the sash. Then nail the string to the boxed frame, but only leave a few inches of string hanging from the head to allow for future adjustments. Bromley double glazing of double-hung windows with a history include a chain or cord attached to the weights which keeps the sashes balanced in the jamb. Over time, these chains may become damaged and make it difficult to raise windows. A new sash cable will restore the ability to move and lower the sash, and keep 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 require removal. It may be possible to remove them with a hammer or chisel, but it is always better to lay out dust sheets prior to beginning any work. Once the access panel is removed, you can start working on the sash. Make the small parting beads (also called “tie rails”) out of their grooves with a chisel or flat bar. They are usually wedged in or nailed, but they can be snipped out which is why it's worth your time here. If the sash is still in place, break the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs attached to each piece. It should now be possible to move the sash back and forth without difficulty, though it will probably need some oil if it feels stiff. With the sash in an open position Take a measurement of the sash chain to reach from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain, and then secure it in the previous step. You can use a hammer and screws or nails, but nails are less likely to cause damage. If you haven't purchased an item that replaces the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. They're not costly and simple to install if you buy them from salvage shops for architectural use. Depending on the size and shape of your window you might need to install one or two sashweights in order to keep the sash open.
