The sash is an inside frame that can move up and down vertically in windows that are open. This article will teach you how to make several simple repairs to sash.
Weather Stripping
Wooden window sashes are a great way to add a classic look to your home. They are also sturdy and last for a long time when they are maintained properly. They may, however, get damaged or deteriorated over time due to exposure or normal wear and tear. Thankfully, sash repair experts can restore your windows to their original condition and keep them looking fantastic for a longer period of time than replacement windows.
Weather stripping is the primary aspect to consider when you are repairing sash windows. It's on both the frame and sash. If it's damaged or worn out, it can lead to drafts and other problems. To fix it, start by finding your window brand 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 to find replacement weather stripping to match.
Then, take it off and set it on a table so that you can reach all four sides. If your sash has a double-hung, you'll also need to take off the weights and their ropes that should have fallen into the pocket of the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut off the old weather stripping at the corners, then remove it by hand or with a putty knife.
After the sash is cleared, you can install the stoppers that separate the two sashes. These are long pieces that split the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also use with a scrap piece of wood.
After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool and let it dry at least one day. When the putty is fully cured it is possible to apply an acrylic latex topcoat. This coating will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports the windows sashes can become worn out over time and use. This could result in a door or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is typically very simple and cost-effective. If a sash isn't easy to operate, try spraying some grease into the jamb channel and then slide it open to see if this solves the issue. If the issue continues it's most likely the sash balance. You will need to take off the window sash in order to reach this hardware.
Window sashes need to be able to open and close with minimal effort. However, this may be difficult if the weights are worn out or the sash connecting rail isn't covered with. This issue could be caused by a number of reasons, such as insufficient maintenance or a mismatched weight rating for the particular sash.
If the hinge arms on a window begin to sag this can cause the sash drag, and then eventually to hit the frame in the opposite corner (Photo 1). To remedy the issue, make sure that the sash is in the proper position within the frame's opening and remove it. If the sash has been screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, windows that are old especially in older houses, could be difficult to open or close. In most instances, a few easy repairs can turn these windows into smooth operators again and save the homeowner money on energy costs.
To complete these repairs to sash, it's important to have all of the necessary tools in place before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back into the correct position after you've finished. Remove the sash and take out all the hardware, including the parting beads, cords, and chains that keep the sash in place. Soften any hardened putty using a heat gun set to medium and equipped with a shield to block the nozzle. Remove the old sash and keep it in a labeled bag.
Sash Weights
Sash weights are able to be replaced to improve the performance of your window sash and decrease the energy cost. Sash weights consist of heavy lead or iron cylinders that are enclosed inside a concealed cavity, and are connected via a rope to the movable window sash. These weights provide counterbalance that allows the window to be closed and opened without using mechanical or electrical devices. If they fail, sashweights are often ignored or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to get back and you'll need to find a replacement that fits correctly. You will also require a new piece string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.
Older windows made of wood are joined by mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the components together. The majority of them are large on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting the glue line using the help of a knife, and then tapping the mortised part loose with mallets.
After the sash has been removed then you can take out the sash stop and gain access to the weight pocket. Usually this is accomplished 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 inner workings.
After the sash has been stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with new. First, weigh the sash to ensure that the weights you've got may not be of the right size. After the new weight has been installed, thread a string through the sash pulling mechanism. Then nail the string to the frame, leaving a few inches of string protruding from the head for future adjustments.
Sash Cords
Most double-hung windows of the past come with a chain or cord connected to the weights that supports and keeps the sashes level in the jamb. Over time these cords can break, making it impossible to raise the window. A new sash cable can restore the ability to raise and lower the sash, and keep it in place when opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually screwed or nailed in and require removal. You might be able to employ a hammer and chisel to remove them, but it's always better to lay down dust sheets before beginning any work.
After you have removed the access panel, you are able to begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with flat bar or chisel. They are usually wedged in or nailed but can be prised free which is why it's worth your time. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer and then remove each wood peg. The sash should be able to move freely, however it might require some lubrication to make it feel less stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley on the top of the jamb to the sash slot in the bottom. Cut the chain or cord and attach it in Step 6 above. You can 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're not costly and easy to install if you buy them at architectural salvage stores. Based on window repairs and shape of your window, you may need to use one or two sashweights in order to keep the sash open.
