The sash is an interior frame that can move vertically up and down in windows that open. This article will show you how to carry out a few simple repairs to the sash. Weather Stripping Wooden window sashes can give a classic look to your home. They are also sturdy and will last for many years if they are properly maintained. However, they can be damaged or degrade in time due to exposure to the elements and wear and wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance much longer than replacement windows. The first step for repair sash window damage is to fix weather stripping. It's found on both the sash and frame. It can cause drafts if it's worn out or 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 get 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 is double-hung, you'll have to take off the weights and their ropes that should have fallen into the intended pocket in the jamb liner. After you've removed the sash, use a utility knife to cut away the old weather stripping at the corners, and then take it off by hand or using a putty knife. After the sash has been cleared it is time to replace the parting stops. These are long pieces that divide the sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also use scrap wood. After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and allow it to dry for at least one day. When the putty is fully cured and dried, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a new look. Sash Hardware The hardware that supports window sashes can wear out over time and use. This could result in the window or door that is difficult to open or close. The good thing is that fixing and replacing this hardware is generally relatively easy and affordable. If you're having difficulty opening a sash spray some grease into the jamb channel. Then, you can slide the sash out to see if this resolves the problem. If not, the issue is most likely due to the balance of the sash and you'll have to take off the sash in order to access this hardware. Window sashes need to open and close with little effort. However, this may be difficult if weights are worn out or the sash-to rail meeting rail is not properly covered with. This problem can be caused by a variety of reasons, such as the lack of maintenance or a mismatched weight rating for the particular window sash. If the hinge arms of a window are starting to slide, this could cause the sash's to drag and eventually land on the frame in the corner in the opposite direction of the hinge arm (Photo 1). To address this problem, first ensure that 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 need to loosen the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3). Because of sagging hinges and a general lack in energy efficiency, old windows particularly those in older homes, can be difficult to open or close. In many cases, a few simple fixes can help these windows function smoothly once more and save homeowners money on their energy bills. To complete these repairs to the sash, it's important to have all of the necessary tools lined up before you begin. Mark the location of the hinge channel on the frame (Photo 1) with a pencil. This will assist you in getting the channel back on position correctly after you've completed. Take the sash off, and remove all the hardware including the parting beads, cords, and chains that keep the sash in place. Soften any putty that has been hardened with the help of a heat gun set at medium and fitted with an nozzle shield. Take off the old sash and store it in a labeled bag. Sash Weights Sash weights are able to be replaced to improve the operation of your window sash, and also reduce the cost of energy. Sash weights are heavy lead or iron cylinders, which are enclosed in a hidden cavity and linked to the moveable the sash with rope. They are counterbalancers that allows the window to be opened and closed without using mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and then turned into scrap when they break; therefore you might need to find replacements. A weight in a sash that has fallen out of the cavity is difficult to get back, so you will want to locate a new one that fits correctly. You will also require a new piece of string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord. Mortise and Tenon joints can be used to join older wood windows. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of these pegs are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife and a mallet. After the sash is removed, you can remove the sash stop and gain access to the weight pocket. This is typically done by drilling tiny holes at the bottom of every jamb. This hole is then covered by a wooden access panel that can be cut off to allow you to observe the inner workings of the frame. After 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 new. Be sure to weigh the sash first to ensure that the weights you've got may not be the correct size. Once the new weight is installed, you can thread a string through the sash pulling mechanism. Then attach the string to the boxed frame, but leave a few inches of string hanging from the head to allow for future adjustments. Sash Cords In most old double-hung window the chain or cord is affixed to the weights. This keeps the sashes within the jamb in a balanced manner. Over time these cords can break, making it impossible to raise the window. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in place when it is opened. The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. These are usually screwed or nailed in and need to be removed. It may be possible to remove them with the hammer or chisel but it is always better to lay out dust sheets before beginning any work. After the access panel has been removed, you can start working on the sash. Prise the narrow parting beads (also known as tie rails) out of their grooves with a chisel or flat bar. window repairs is essential to take your time as they're often placed in a wedge or nail. If the sash remains in place, remove the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then remove the wood pegs that are on each piece. The sash should be able move freely, however it may need some lubrication to make it feel less stiff. Measure the length of sash chain/sash cord required to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut the cord or 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 an item that replaces the old counterbalance system, it's recommended to keep the original balancing weights in place. It's cheap to purchase them from architectural salvage stores and they'll be easy to install once you have the sash unlocked. Based on the size and shape of your window you may require one or two sashweights to keep the sash open.
