Take the sash off, and mark its size and width so that you can get new weather stripping that is compatible with the original.
Then, remove the sash and place it on a surface so that you can reach all four sides. If your sash is double-hung, you’ll also need to take off the weights and their ropes, which should have fallen into the pocket of the jamb liner. After you’ve removed the sash using a utility knife, you can use it to remove the weather stripping that was formerly in place at the corners. Then, remove it manually or using a putty blade.
After the sash has been cleared, you can install the stoppers that separate the two sashes. 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. However, you can also use scrap wood.
After removing the stopper and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty knife, and let it dry for at least one 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 holds window sashes is susceptible to wear and tear from age and window repairs use and the result could be a window or door that isn’t able to open or close easily. The good news is that repairing and replacing this hardware is usually relatively easy and affordable. If you’re having trouble opening a sash, spray some oil into the jamb channel. Then, slide the sash up and open to see if this resolves the issue. If not, the problem is likely with the sash balance and you’ll need to remove the sash to gain access to this hardware.
Ideally, window sashes should move open and shut 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 problem can be caused by a variety of reasons, such as lack of maintenance or by the wrong weight rating for the specific sash.
If the hinge arms of a window begin 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 correct the issue ensure that the sash is in the proper position within the frame opening and then take it off. If the sash is secured to the hinge arm, you’ll need to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Because of sagging hinges and a general deficiency in energy efficiency, older windows especially in older houses, could be difficult to open and close. Many times, a few simple fixes can help these windows function smoothly once more and save homeowners money on energy costs.
To make 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 with pencil (Photo 1). This will help you get the channel back on the correct position after you’ve finished. Then, remove the sash and remove the hardware including the parting beads (Photo 2) and the cords or chains which hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash, and put it in a bag with a label.
Sash Weights
Sash weights are able to be replaced to improve the performance of your window sash and reduce energy costs. Sash weights are hefty lead or iron cylinders, which are enclosed in a hidden cavity and connected to the movable the sash with rope. They are counterbalancers which allows the window to be shut and opened without using mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they fail. Consequently you may have to locate replacements.
It’s difficult to retrieve an sash-weight which has fallen from the cavity, so you’ll need to find one that is suitable for the. You will also require a fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Mortise and Tenon joints are used to join older wood windows. Pin punch and hammer can be used to take out the wood pegs that hold the components together. Most of them have large diameters on one side and a smaller diameter on the other side, so it is essential to remove the smaller-diameter ones first. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using a knife, then tapping the mortised area loose using mallets.
Once the sash is freed, you can remove the sash stop and gain access to the weight pocket. This is usually done via an opening at the bottom of every jamb. This hole is then covered by an access panel of wood which can be removed to allow you to observe the inner workings of the frame.
When the sash has been shut off and the access panel is removed, you are able to remove the weight that was previously installed and replace it. Weigh the sash first because the weights you have may not be of the right size. Once the new weight is installed, tie a string to it and thread it through the pulley of the sash. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the top of the string to allow future adjustments.
Sash Cords
In most old double-hung window the chain or cord is attached to the weights. This helps keep the sashes of the jamb level. Over time, these chains can get damaged and make it difficult to raise the windows. A new sash cable will give you the ability to move and lower the sash and keep it in place when opened.
The first step to replace cords for sash is to locate and remove the access panels within the jambs. These are usually screwed or nailed into and must be removed. It is possible to take them out using a hammer or chisel, however, it is best to lay out dust sheets before beginning any work.
Once the access panel is removed, you can start working on the sash. Make the small parting beads (also called «tie rails») out of their grooves with the chisel or flat bar. They are typically wedged into or nailed in, but they can be prised free which is why it’s worth your time. If the sash is still in place, pry the mortise and tenon joints free using a hammer or screwdriver and then remove each wood peg. The sash should be able to move freely, however it may need some lubrication to make it feel less stiff.
With the sash open With the sash in an open position, measure the sash chain or cord to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and then secure it in the step 6 above. You can do this with a hammer, nails or screws. However nails are less likely to cause damage.
If you haven’t purchased a kit that replaces the old counterbalance system it’s recommended to keep the original balancing weights in place. They are not expensive and simple to install if purchased them at architectural salvage stores. Based on the size and shape of your window, you may require one or two sashweights in order to keep the sash open.
