To fix it, begin by determining your window's brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). 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, you can remove the sash from its holder and place it on a flat surface to allow you to reach all four sides. If your sash has been double-hung, take out the ropes and weights that should fall into the pocket within the jamb lining. After you've removed the sash using a utility knife, you can use it to cut off the weather stripping from the corners, then take it off by hand or with a putty knife.
When the sash is clean, you can replace the parting stops. These are long pieces that divide 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 replace them with scrap wood.
After removing the stoppers for parting and cutting them to the desired length, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using a putty tool, and allow it to dry for at least one day. Once the putty has fully cure it is possible to apply a topcoat of acrylic. This coating will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that supports the window sashes may wear out over time and use. This could lead to windows or doors that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often easy and affordable. If you're having trouble opening the sash, spray some grease into the jamb channel. Then slide the sash open to see if it resolves the problem. If not, the problem is likely to be with the sash balance, and you'll need to remove the sash to gain access to the hardware.
Window sashes should open and close without much effort. However, this may be difficult if weights are worn out or the sash meeting rail is not properly covered with. This can be due to a variety of factors such as an absence of maintenance or an unmatched weight rating.
If the hinge arms on a window begin to sag this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To resolve this problem, first ensure that the sash fits squarely in the opening of the frame and then take it out of the window. If the sash was fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Old windows, particularly those in older houses, can be difficult to open and close due to sagging hinges and a general inefficiency. Sometimes, a few simple fixes can help these windows function smoothly once more and save homeowners money on their energy bills.
To make these repairs to the sash it is essential to have all of the tools needed before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will help you to position the channel in the proper location after you've completed. Remove the sash and then remove all hardware, including the parting beads, cords, and chains that hold the sash in place. The nozzle shield of the heat gun and a medium setting will soften any hardened glue. Take off the old sash and put it in a bag with a label.
Sash Weights
Sash weights can be replaced to improve the performance of your window sash and reduce the energy cost. Sash weights consist of iron or lead cylinders that are enclosed in a concealed cavity and connected by ropes to the movable window sash. These weights function as counterbalances and allow you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights are usually neglected or not used by homeowners.
A weight from a sash that fell out of the cavity is difficult to get back, so you will want to find a new one that fits properly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord.
Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that keep the parts together can be removed using the use of a pin punch and hammer. The majority of them have large diameters on one side and a smaller size on the other, so it is crucial to take out the smaller-diameter ones first. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting the glue line using a knife, then tapping the mortised section loose using mallets.
After the sash has been removed, you can remove the sash stop and access the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with a wooden access panel that can be cut off so that you can 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 you used and replace it. Make sure you weigh the sash prior to you do this, since the old weights may be different sizes than the one you need. After the new weight is installed then tie a string to it and then thread it through the sash pulley. Then, you can nail the string to the frame, leaving a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This supports and keeps the sashes within the jamb balanced. As time passes, these cords can become damaged and render it impossible to raise 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. They are typically fixed or screwed in and will require to be removed or relocated. You might be able to use a hammer and chisel for removing them however, it is always best to lay down dust sheets before beginning any work.
After removing 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 the chisel or flat bar. It is important to take your time because they are usually placed in a wedge or nail. If the sash is still in place, pry the mortise and tenon joints free with a screwdriver or hammer and then take out each wood peg. The sash should move around freely now, however it might require some lubrication to feel less stiff.
With the sash in an open position, measure enough sash cord/chain to extend from the pulley in the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then secure it in the step 6 above. You can do this with a hammer, nails or screws. However, nails are less likely than screws 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. They're not expensive and easy to install if purchased them from architectural salvage stores. Depending on the size of your window one or two sashweights could be needed to keep the sash in an open position.
