The sash is an inside frame that is able to move vertically up and down in windows that open. This article will teach you how to perform several simple repairs to sash.
Weather Stripping
Wooden window sashes can add an elegant look to your home. They are also sturdy and can last many years provided they are properly maintained. However, they can become damaged or deteriorate over time because of exposure to the elements and wear and wear and tear. However, sash repair experts can restore your windows to their original condition and keep them looking great for much longer than newer replacement windows.
The first step to sash window repair s is addressing weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it could cause drafts and other issues. Start by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corners or on the aluminum spacers between panes). Remove the sash, and mark its width and height so that you can purchase new weather stripping that is compatible with the original.
Then, remove the sash from its holder and place it on a flat surface to allow you to access all four sides. If your sash was double-hung, take out the ropes and weights that should be buried in the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the weather stripping that was formerly in place at the corners, and then take it off by hand or using a putty knife.
Once the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also replace them with scrap wood.
After removing the stopper for the parting and trimming it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a day. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports window sashes can wear out over time and use. This could lead to windows or doors that is difficult to open or close. The good news is that repairing and replacing this hardware is generally quite simple and inexpensive. If a sash is difficult to operate you can try spraying some grease into the jamb channel then open it to see if it solves the issue. If the problem persists it's most likely to be due to the sash's balance. It is necessary to remove the window sash to reach this hardware.
Ideally, window sashes should be able to open and close with very little effort, but this can be a difficult task when the weights are worn or if the sash's meeting rail isn't properly glazed. This problem can be caused by a number of reasons, such as the lack of maintenance or the wrong weight rating for a particular sash.
If the hinge arms 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 resolve this problem, first ensure that the sash fits squarely in the opening of the frame and then take it out of the window. If the sash was attached to the hinge arm, remove the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Old windows, especially those in older homes, may be difficult to close and open because of sagging hinges and a general lack of energy efficiency. In many cases, a few simple fixes can make these windows operate smoothly once more and help homeowners save money on their energy bills.
It is essential to have the tools you need before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will allow you to put the channel in the proper position after you've finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any hardened putty using the help of a heat gun set at medium and equipped with an shield to block the nozzle. Take off the old sash and keep it in a bag labeled.
Sash Weights
Whether your window sash repairs are to replace a broken cord or just to keep your windows functioning by replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are made of heavy iron or lead cylinders that are encased in a concealed cavity and are connected via ropes to the movable window sash. They provide counterbalance, allowing the window to be shut and opened without the use of electrical or mechanical devices. When they fail, sashweights are usually neglected or not used by homeowners.
It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights to the sash cord.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the components together. The majority of these pegs are big on one side, but smaller on the other. It is crucial to first remove the smaller diameter sides. Sashes made later in the century used glue instead of pegs. They can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised area loose using mallets.
After the sash is removed and removed, you can take off 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 covered with 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 will be able to take off the weight of the old sash and replace it with new. Make sure you weigh the sash before you begin, as the weights that were previously used may be different in size from what is needed. Once the new weight is installed, tie a string to it and then thread it through the pulley for the sash. Then nail the string to the frame, but only leave a few inches of string protruding from the head to allow for future adjustments.
Sash Cords
Most old double-hung windows come with a chain or cord attached to the weights that supports and keeps the sashes in balance in the jamb. Over time, these cords can get damaged and render it impossible to raise windows. A new sash cable will restore the ability to raise and lower the sash and ensure it stays in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and will need to be removed or repositioned. You may be able to employ a hammer and chisel for removing them but it's best to lay down dust sheets before commencing any work.
After the access panel has been removed, you can begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. It is essential to be patient because they are usually wedged or nailed in place. If the sash is in place, remove the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then remove the wood pegs that are on the components. The sash should be able move freely, however it might require some lubrication to feel less stiff.
Determine the length of sash cord/chain required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the chain or cord and then fix it using the previous step. You can either use a hammer and screws or nails, however nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you have purchased a kit that will replace the counterbalance. They are not expensive and simple to install if purchased them from salvage shops for architectural use. Depending on the size and shape of your window you may require one or two sashweights in order to keep the sash open.
