Window Sash Repairs Sashes for windows must be inspected regularly for signs of mold, mildew and damage. You can reduce future repair costs by catching problems early before they become out of control. The sash is an interior frame that is vertically moved upwards or downwards in windows that are open. This article will demonstrate how to perform several simple repairs to sash. Weather Stripping Wood window sashes give the classic look to your home. When properly maintained, they can last for years. However, they may become damaged or degrade in time because of exposure to the elements and wear and tear. Sash repair specialists can restore windows to their original condition and maintain their appearance much longer than replacement windows. The first step in repair sash windows is to address weather stripping, which can be found on both the sash as well as the frame. It could cause drafts if worn or loose. To fix it, begin by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height so that you can locate new weather stripping that matches. Then, remove the sash and place it on a table to allow access to all four sides. If your sash has been double-hung, you must remove the weights using their ropes that should fall into the pocket inside the jamb lining. Once you've taken the sash off using a utility knife, you can use it to cut away the old weather stripping at the corners, then remove it by hand or using a putty knife. Once the sash is clear, you can replace the parting stops. These are long pieces that separate the sashes. Pam likes to replace them with standard ½-inch by ¾-inch window trim from the lumberyard, but you can also use a piece of scrap wood. After removing the stopper for the parting and cutting it to length after which, 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 a minimum of a day. Once the putty has fully cure and dried, you can apply a topcoat of acrylic. This will protect the putty, and give your sash an updated appearance. Sash Hardware The hardware that holds the window sashes may wear out with time and use. This could result in a door or a window that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically simple and inexpensive. If you are having trouble opening the sash, spray some lubricant into the jamb channel. Then, slide the sash open to see if that fixes the problem. If not, the issue is likely to be with the sash balance, and you'll need to remove the sash to gain access to this hardware. Window sashes should open and close with little effort. However, double glazing Chiswick can be difficult if the weights are worn out or the sash connecting rail isn't coated. This problem can be caused by a variety of things, such as the lack of maintenance or the wrong weight rating for the specific sash. If the hinge arms of a window are starting to slide, this could cause the sash to slide and eventually hit the frame in the corner that's directly opposite the hinge arm (Photo 1). To resolve this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash is screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash (Photo 3). Old windows, particularly those in older homes, may be difficult to close and open due to hinges that are sagging and an overall lack of energy efficiency. In many cases just a few easy fixes can make these windows operate smoothly again and save homeowners money on energy costs. It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will assist you in getting the channel back in place correctly when you're finished. Take the sash off and then remove all hardware, including the beads for parting cords, chains, and cords that keep the sash in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash and put it in a bag labeled. Sash Weights No matter if your window sash repair needs are to replace a broken cord or to keep your windows functioning, replacing worn out sash weights will improve sash operation and reduce energy consumption. Sash weights are heavy, lead or iron cylinders enclosed in a concealed cavity and attached to the movable the sash with a rope. They are counterbalancers that allows the window to be closed and opened without using mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners, and are turned into scrap when they fail. Consequently, you may need to find replacements. It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also require a new piece string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord. Older windows made of wood are joined with mortise and tenon joints. The wood pegs that keep the parts together can be removed with the use of a pin punch and hammer. The majority of them have an enormous diameter on one side and a smaller size on the other, which is why it is important to remove the smaller-diameter ones first. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised part loose using a mallet. Once the sash has been removed, you can take off the sash stops and gain access to the weight pockets. Usually it is done by drilling a hole near the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inside workings. After the sash has been stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with the new. Be sure to weigh the sash before you begin, as the weights that were previously used may be different in size from the one you need. Once the new weight is installed then tie a string to it and thread it through the pulley for the sash. Then, you can nail the string to the boxed frame, but leave a few inches of string protruding from the head for future adjustment. Sash Cords In most old double-hung window, a cord or chain is affixed to the weights. This supports and keeps the sashes in the jamb level. Over time, these chains can become damaged and make it difficult to raise windows. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in position 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. They are usually screwed or nailed into and need to be removed. You could use a hammer and chisel to prise them off but it's best to lay down dust sheets prior to beginning any work. After removing the access panel, you are able to begin to work on the sash. Use a flat bar or chisel, to pry the narrow parting beads out of their grooves. It is important to be patient as they're often wedged or nailed in place. If the sash is still in place, remove the mortise and the tenon joints by using a hammer and pin punch or screwdriver, and then take out the wood pegs attached to the components. You should now be able to move the sash around freely, though 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 at the bottom from the pulley located at the top of the jamb. Cut the chain or cord and fix it as described in the previous step. You can use either nail, hammer or screws. However nails are less likely than screws 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. They're not expensive and are easy to install if purchased them from salvage shops for architectural use. Based on the size and shape of your window, you may require one or two sashweights to keep the sash open.
