Window Sash Repairs
Check the windows sashes regularly for signs of damage, mildew and mold. You can save future repair costs by catching these issues in the early stages, before they become too much.
The sash is an inside frame that moves vertically up and down in windows that are open. This article will show you how to perform easy repairs to your sash.
Weather Stripping
Wood window sashes add a classic aesthetic to your home. When properly maintained, they can last for a long time. However, they can become damaged or deteriorate as time passes because of exposure to the elements and wear and wear and tear. Sash repair specialists can restore windows to their original state and maintain their beauty longer than replacement windows.
Weather stripping is the first issue to take care of when fixing windows with sash. It is located on both the frame and the sash. It can cause drafts if worn or loose. Start by identifying the window's brand and the date of manufacture for the glass (etched on the corner of the glass or the aluminum spacers between panes). Take the sash off and mark its size and width so that you can find a new weather stripping that is compatible with the original.
Then, remove the sash from the holder and place it on flat surfaces to allow you to see all four sides. If your sash is double-hung, you'll need to remove the weights and their ropes, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash with the utility knife, remove the old weather stripping by hand or with the putty blade.
Once the sash is clear and clean, you can put in the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also substitute with a scrap piece of wood.
After removing the stoppers for parting and trimming 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, then let it dry for at least a few days. When window repairs 's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that supports the window sashes can wear out over time and with use. This could lead to the window or door 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 isn't easy to operate try spraying lubrication into the jamb channel then open it to see if this resolves the issue. If the problem persists it's most likely that the sash balance is off. It is necessary to remove the window sash to reach this hardware.
Ideally, window sashes should swing open and closed with very little effort, however, this can be difficult when the weights are worn or if the sash's meeting rail isn't properly glazed. This issue can be caused by a number of factors, including the lack of maintenance or an incorrect weight rating for a particular sash.
If the hinge arms of a window begin to sag, this can cause the sash to slide and eventually land on the frame in the corner opposite the hinge arm (Photo 1). To address 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 has been attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old particularly those in older houses, could be difficult to open and close. In most instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner money on 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) with pencil. This will help you get the channel back in place correctly when you're finished. Take the sash off, and remove all the hardware, including the beads for parting, cords, and chains that keep the sash in place. A hot gun with nozzle shield and medium setting will soften any putty that has been hardened. Take off the old sash and put it in a bag that is labeled.
Sash Weights
Sash weights can be changed 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 hidden cavity and attached to the movable the sash with rope. These weights act as counterbalances, allowing you to open and close the window without having to use mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they fail; therefore, you may need to find replacements.
It is difficult to recover an sash-weight which has fallen from the cavity, so you'll need to find one that fits properly. You will also require a new piece string, a length sashcord and a few sashpulleys to secure the weights you are replacing to the cord.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to remove the wood pegs holding the components 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. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line with the help of a knife, and then tapping the mortised section loose with mallets.
Once the sash is freed, you can remove the stopper on the sash and get access to the weight pocket. Usually it is done by drilling an opening in the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the inside workings.
When the sash has been shut off and the access panel has been removed, you can remove the old weight and replace it. Be sure to weigh the sash prior to you do this, since the old weights may be a different size than what is needed. Once the new weight is in place, 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 adjustments.
Sash Cords
In the majority of old double-hung windows the chain or cord is affixed to the weights. This keeps the sashes within the jamb level. Over time these cords can break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash, and keep it in position when opened.
The first step to replace sash cords is to locate and remove the access panels in the jambs. They are usually screwed or nailed into and must be removed. You may be able to use a hammer or chisel for removing them but it's best to lay down dust sheets before beginning any work.
After you have removed the access panel, you are able to begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with flat bar or chisel. It is essential to take your time because they are usually wedged or nailed in place. If the sash remains in place, pry the mortise-and-tenon joints out using a hammer or screwdriver and then remove each wood peg. It should now be possible to move the sash back and forth freely, though it will probably need some lubrication if it feels stiff.
With the sash open, measure enough sash cord/chain to reach from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then secure it in the step 6 above. You can either use a hammer and nail or screws, but nails are less likely to cause damage.
If you haven't purchased an item that replaces the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. They're not expensive and are easy to install if purchased them at architectural salvage stores. Based on the size and shape of your window, you might need to install one or two sashweights in order to keep it open.
