Start by identifying the window's brand and the 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 that you can locate new weather stripping that matches.
Then, you can remove the sash from its holder and place it on flat surfaces to allow you to access all four sides. If your sash has a 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 you've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners, then remove it manually or with a putty knife.
After the sash has been cleared, you can install the stoppers that separate the two sashes. These are long pieces of wood that are used to separate the two sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also use for a scrap piece of lumber.
After removing the parting stops and trimming them to your desired length then apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. When the putty is fully dried and dried, you can apply an acrylic latex topcoat. This coating will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes prone to wearing out from age and use, and the result can be a window or door that can't be opened or closed easily. The good thing is that fixing and replacing this hardware is generally very simple and cost-effective. If a sash is difficult to operate try spraying grease into the jamb channel, and then slide it open to see if this resolves the issue. If the problem persists, it is most likely to be due to the sash's balance. You will need to remove the window repair sash in order to reach this hardware.
Ideally, window sashes should swing open and closed without effort, however, this can be difficult when the weights are worn or if the sash that joins rail isn't properly glazed. This issue can be due to a variety of factors, including an absence of maintenance or an unmatched weight rating.
If the hinge arms of a window repair are starting to sag, this can cause the sash's to drag and eventually hit the frame in the corner directly opposite the hinge arm (Photo 1). To address this problem, first ensure that the sash fits squarely in the opening of the frame and then remove it from the window. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Because of sagging hinges and a general lack of energy efficiency, old windows particularly those in older houses, could be difficult to open or close. In many cases just a few easy fixes can help these windows function smoothly once more and help homeowners save money on energy bills.
It is essential to have the tools you require before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will help you to place the channel in the correct position after you've finished. Take the sash off and take out all the hardware, including the beads for parting, cords, and chains that keep the sash in place. Heat gun with nozzle shield and a medium setting will soften any hardened putty. Remove the old sash, window repair and put it in a labeled bag.
Sash Weights
If your window sash repairs are to replace a damaged cord or simply to ensure that the windows are functional by replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed in a concealed cavity and linked to the moveable the sash with rope. They function as counterbalances, allowing you to open and shut the window without having to use mechanical or electrical devices. The sash weights are usually disregarded or disabled by homeowners, and are turned into scrap when they fail; therefore you might need to search for replacements.
It's difficult to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Older wood windows are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed using pin punches and hammers. Most of these pegs have large diameters on one side and a smaller size on the other, which is why it is essential to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be separated by using a knife or a mallet.
Once the sash has been removed, you can take off the stops on the sash and get access to the pockets for weights. Usually it is done by drilling an opening in the bottom of each jamb. This hole is covered with a 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 take off the weight of the old sash and replace it with the new. Be sure to weigh the sash first, as the weights you've got may not be the right size. After the new weight is installed, tie a string to it and thread it through the pulley of the sash. Then, attach the string to the boxed frame. Leave a few inches protruding at the head of the string to allow future adjustments.
Sash Cords
In the majority of double-hung windows, a cord or chain is connected to the weights. This helps keep the sashes within the jamb in a balanced manner. Over time, these cords could break, making it difficult to raise the window. A new sash cord will 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 usually screwed or nailed in and require removal. You could employ a hammer and chisel to prise them off but it's best to lay down dust sheets before commencing any work.
Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using a chisel or flat bar. They are usually wedged in or nailed, but they can be snipped out and it's worth your time. If the sash is still in place, break the mortise-and tenon joints with a screwdriver or hammer and then remove each wood peg. You should now be able to move the sash around without difficulty, though it will probably need some oiling if it seems stiff.
Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom from the pulley at the top of the jamb. Cut the cord/chain and then fix it as described in Step 6 above. You can use either nail, hammer or screws. However, nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system, it's recommended to keep the original weights for balancing in place. It's not expensive to buy them from architectural salvage stores and they'll be easy to install once you have the sash unlocked. Depending on the dimensions and shape of your window you might need to install one or two sashweights to keep the sash open.
