To fix it, start by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off and mark its width and height so that you can find a replacement weather stripping that matches.

Then, take the sash from the holder and place it on an even surface that allows you to see all four sides. If your sash was double-hung, take out the ropes and weights that should have fallen into the pocket in the jamb lining. After you've removed the sash and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners. Then, take it off by hand or using a putty knife.

When the sash is clean, you can replace the parting stops. They are long pieces of wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you can also use scrap wood.

After removing the parting stop and trimming it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife and let it dry for a minimum of a day. After the putty has completely cured it is possible to apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from time and usage and the result could be a window or door that won't open or close easily. It's good to know that replacing or repairing this hardware is often easy and affordable. If a sash isn't easy to operate you can try spraying some grease into the jamb channel then slide it open to see if this fixes the problem. If the issue persists it's likely that the sash balance is off. You will need to take off the window sash to access the hardware.

Ideally, window sashes must swing open and closed without effort, however, this can be difficult when the weights wear out or if the sash that joins rail isn't properly glazed. This issue can be caused by a number of factors, including insufficient maintenance or an incorrect weight rating for the specific window sash.

If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually strike the frame in the corner that's directly opposite the hinge arm (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash was fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, windows that are old especially in older homes, may be difficult to open or close. In most cases, a few simple repairs can transform these windows into smooth operation and save homeowners money on energy costs.

In order to make these repairs to the sash it is essential to have all the necessary tools lined up before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will assist you in getting the channel back into 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 that hold it in place. A hot gun with nozzle shield and a medium setting will soften any hardened putty. Remove the old sash and keep it in a bag with a label.

Sash Weights

Sash weights can be changed to enhance the efficiency of your window sash and reduce the cost of energy. Sash weights are heavy lead or iron cylinders that are enclosed in a hidden cavity and connected to the movable window sash using a rope. They function as counterbalances, which allows you to open and close the window without having to use mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.

It is difficult to recover the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a new piece of string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. The majority of these pegs have an enormous diameter on one side and a smaller one on the other, so it is crucial to take out the small-diameter sides first. Sashes made later in the century used glue instead of pegs. They can be separated by cutting the glue line using the help of a knife, and then tapping the mortised section loose with a mallet.

After the sash has been removed then you can take out the sash stop and access the weight pocket. Usually, this is done through a hole near the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inside workings.

After the sash has been stopped and the access panel removed, you will be able to take off the old sash weight and replace it with new. First, weigh the sash to ensure that the weights you have might not be the right size. After the new weight is installed, run the string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches protruding at the end of the string to allow for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord attached to the weights that helps keep the sashes in balance in the jamb. Over time, these chains can get damaged and make it impossible to raise the windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in place when opened.

The first step to replace cords for sash is to locate and take out the access panels located in the jambs. These are usually installed by screws or nails and must be removed or repositioned. You might be able to use a hammer and chisel to remove them, but it's always better to lay down dust sheets before starting any work.

Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with a chisel or flat bar. It's important to be patient as they're often placed in a wedge or nail. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer and then remove each wood peg. It should now be possible to move the sash around freely, though it will probably need some oiling if it seems stiff.

Take a measurement of the length of sash cord/chain needed to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the chain or cord, and then attach it as described in the previous step. You can use a hammer, nails or screws. However, nails are less likely to cause damage.

It is best to keep the original weights if you have purchased a kit that will replace the counterbalance that was previously installed. They are not expensive and easy to install if you purchase them at architectural salvage stores. Depending on the size and shape of your window you might need to install one or two sashweights in order to keep the sash open.
