Window Sash Repairs
Make sure to check the sashes of your windows regularly for any damage, mildew and mold. You can avoid the cost of repairs in the future by catching problems in the early stages before they get out of hand.
The sash is an interior framing that moves vertically upwards or downwards in windows that are open. This article will teach you how to do simple sash repairs.
Weather Stripping
Wooden window sashes can add a classic look to your home. They are also durable and last for a long time when they are maintained properly. However, they can be damaged or degraded in time because of exposure to the elements and wear and wear and tear. Fortunately, sash repair specialists can restore your windows back to their original condition and keep them looking fantastic for a longer period of time than replacement windows.
Weather stripping is the most important aspect to consider when you are repairing windows that have sash. It is located on both the frame and the sash. If it's worn or loose, out, it could cause drafts and other issues. Start by identifying the brand of window and the glass manufacturer's date (etched on the glass's corners or the aluminum spacers between panes). Then, remove the sash and mark its width and height, so you can find new weather stripping that matches.
Then, you can remove the sash from its holder, and place it on a flat surface to allow you to access all four sides. If your sash has a double-hung, you'll need to remove the weights and the ropes that go with them, which should have fallen into the pocket of the jamb liner. Once you've removed the sash using a utility knife, you can use it to cut away the weather stripping from the corners, and then take it off by hand or with a putty knife.
After the sash is cleared, you can install the stoppers that separate the two sashes. They are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you can also use scrap wood.
After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, and let it dry at least one day. Once it's fully cured, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that supports window sashes prone to wearing out from the wear and tear of use and the result could be a window or door that can't be opened or closed easily. It's good to know that replacing or fixing this hardware is usually simple and inexpensive. If a sash isn't easy to operate you can try spraying some grease into the jamb channel then slide it open to see if that resolves the issue. If not, the problem is likely with the sash balance, and you'll need to remove the sash to access this hardware.
Ideally, window sashes should swing open and closed with very little effort, but this can be difficult if the weights become worn or if the sash's meeting rail isn't properly glazed. This issue can be caused by a number of factors, including lack of maintenance or by a mismatched weight rating for the specific window sash.
If the hinges on a window begin to sag this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To remedy window repairs ensure that the sash is aligned in the frame opening and then remove it. If the sash is screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).
Windows that are old, especially in older homes, may be difficult to close and open because of sagging hinges and an overall lack of energy efficiency. In most cases, a few simple repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy bills.
To complete these repairs to the sash it is important to have all of the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will assist you in getting the channel back into place correctly when you're finished. Then, remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with a shield to block the nozzle. Take off the old sash and put it in a labeled bag.
Sash Weights
Sash weights can be replaced to improve the performance of your window sash and reduce the cost of energy. Sash weights are heavy, lead or iron cylinders enclosed in a concealed cavity and linked to the moveable window sash using rope. These weights act as counterbalances, which allows you to open and shut the window without requiring mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and then turned into scrap when they fail. Consequently, you may need to search for replacements.
A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a new one that is suitable for the. You will also require a new piece of string, a length of sash cord and some sash pulleys to connect the new sash weights onto the sash cord.
Older windows made of wood are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the parts together. The majority of these pegs have a large diameter on one side and a smaller one on the other side, so it is essential to remove the smaller-diameter ones first. Sashes that were made later in the century utilized 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 section loose using a mallet.
Once the sash has been released, you can remove the sash stops and access the weight pockets. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with an access panel of wood that can be cut off to allow you to see the inner workings of the frame.
After the sash has been stopped and the access panel removed, you will be able to take off the old sash weight and replace it with new. Be sure to weigh the sash first, as the weights you have might not be the correct size. Once the new weight is in place, tie a string to it and then thread it through the pulley of the sash. Then, you can nail the string to the boxed frame, but only leave a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
The majority of double-hung windows with a history include a chain or cord connected to the weights that supports and keeps the sashes in balance within the jamb. Over time, these cords can get 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.
To replace sash cords the first step is to remove the access panels from the jambs. They are typically screwed or nailed into and must be removed. You could use a hammer or chisel to remove them but it's best to lay down dust sheets prior to commencing any work.
After you have removed the access panel, you can begin to work on the sash. Utilize a flat bar or chisel, to pry the tiny parting beads out of their grooves. They are typically wedged into or nailed but can be removed, so it's worth taking your time. If the sash remains in place, break the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then unhook the wood pegs attached to each component. The sash should be able to move around freely now, however it may require some lubrication in order to feel less stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to reach from the pulley in the top of the jamb to the sash slot at the bottom. Cut the chain or cord, and then attach it as described in Step 6 above. You can either use a hammer and screws or nails, however nails are less likely to cause damage.
It's best to leave the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance that was previously installed. They are not expensive and simple to install if you purchase them from architectural salvage stores. Based on the dimensions and shape of your window you may require one or two sashweights in order to keep it open.
