Window Sash Repairs Regularly inspect the window sashes for damage, mildew, and mold. By catching these problems early, you can save money on repairs in the future. The sash is an internal frame that can move up and down vertically in windows that are open. This article will teach you how to make several easy repairs to your sash. Weather Stripping Wooden window sashes are a great way to add an elegant appearance to your home. They are also sturdy and will last for many years when they are maintained properly. However, they can be damaged or degraded over time due to exposure or normal wear and tear. Sash repair specialists can restore windows back to their original condition and keep them looking great longer than replacement windows. The first step for repair sash window damage is to fix weather stripping, which is found on both the sash and frame. If it's worn or loose, out, it can cause drafts and other issues. To fix it, start by finding your window brand 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 width and height so that you can get replacement weather stripping that matches. Then, you can remove the sash from the holder and place it on a flat surface to allow you to reach all four sides. If the sash is double-hung, you must remove the weights using their ropes that should be buried in the jamb lining. Once you've removed the sash and the weights, use a utility knife to cut away the weather stripping that was formerly in place at the corners. Then, remove it by hand or using a putty knife. When the sash is clean, you can replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard ½-inch-by ¾-inch window trim from the lumberyard, but you can also replace them with a piece of scrap wood. After removing the stopper for the parting and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound using your putty knife, and allow it to dry for at least a day. Once the putty has fully dried it is possible to apply a topcoat of acrylic. This will protect the putty and give your sash an updated look. Sash Hardware The hardware that supports window sashes prone to wearing out from time and usage and the result could be a door or window that won't open or close easily. It's good to know that replacing and fixing this hardware is usually easy and affordable. If you're having difficulty opening a sash spray some grease into the jamb channel. Then slide the sash up and open to see if it resolves the problem. If not, the problem is likely with the sash balance and you'll need to take out the sash in order to access this hardware. Sashes for windows should be able to be able to open and close with minimal effort. However, this can be a challenge if the weights have been worn out or the sash-to rail meeting rail is not properly covered with. This can be due to a variety of factors such as a lack of maintenance and a mismatched weight rating. If the hinge arms of a window are beginning to slide, this could cause the sash's to drag and eventually strike the frame in the corner directly opposite the hinge arm (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 secured to the hinge arm, you'll have to unscrew 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 houses, could be difficult to open and close. In most instances, a few minor repairs can turn 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 location of the hinge channel on the frame (Photo 1) with pencil. This will allow you to get the channel back on the correct position after you've finished. Take the sash off and then remove all hardware including the parting beads, cords, and chains that keep the sash in place. Soften any putty that has been hardened with a heat gun set to medium and fitted with a shield to block the nozzle. Take off the old sash and keep it in a labeled bag. double glazing Welwyn Garden City Whether your window sash repairs are to replace a broken cord or simply to keep the windows functional, replacing worn out weights on sash can improve sash operation and help reduce energy consumption. Sash weights are composed of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and are connected via ropes to the moveable window sash. They function as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners. A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a replacement that fits properly. You will also require an additional piece of string, a length sash cord and some sash pulleys that will tie the new sash weights onto the sash cord. Mortise and Tenon joints can be used to join old wood windows. The wood pegs holding the parts together can be removed with a pin punch and hammer. The majority of them are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated by using a knife or mallet. Once the sash is freed, you can remove the sash stop and gain access to the weight pocket. This is usually done via a small hole at the bottom of each jamb. This hole is then covered by a wooden access panel that can be ripped off to allow you to see the inner workings of the frame. After the sash has been stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with new. Be sure to weigh the sash first, as the weights you've got may not be the correct size. After the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then attach the string to the boxed frame, but leave a few inches of string sticking out from the head to allow for future adjustments. Sash Cords In the majority of old double-hung windows, a chain or cord is affixed to the weights. This supports and keeps the sashes of the jamb balanced. Over time these cords can break, making it impossible to raise the window. A new sash cable will restore the ability to raise and lower the sash, and ensure it stays in place when opened. The first step in replacing cords for sash is to locate and remove the access panels in the jambs. They are usually screwed or nailed in and must be removed. You may be able to employ a hammer and chisel to remove 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. Use a flat bar or chisel to pry the small parting beads from their grooves. It is essential to be patient, as these are often placed in a wedge or nail. If the sash is still in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, and then take out the wood pegs attached to the components. The sash should be able move freely, however it may need some lubrication to make it feel less stiff. With the sash open, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it as in Step 6 above. You can either employ a hammer, nail or screws, but nails are less likely to cause damage. Unless you've bought a kit that replaces the old counterbalance system, it's recommended to keep the original weights for balancing in place. They are not expensive and simple to install if purchased them from salvage shops for architectural use. Based on the dimensions and shape of your window you might need to install one or two sashweights in order to keep the sash open.
