To fix it, begin by determining your window's 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, remove the sash and place it on a work surface to allow access to all four sides. If your sash has been double-hung, remove the weights with their ropes that should be buried within the jamb lining. After you have removed the sash using the utility knife, you can remove the weather stripping from the old sash by hand or with the putty blade.

After the sash is cleared, you can install the parting stops. They are long pieces of wood that divide the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trimming from the lumberyard. But, you can also substitute a scrap piece of wood.

After removing the stoppers for parting and trimming them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash.

Sash Hardware

If a sash becomes difficult to operate, try spraying some lubrication into the jamb channel then open it to see if this resolves the issue. If not, the issue is most likely due to the sash balance, and you'll have to take off the sash in order to access this hardware.

Window sashes need to open and close without much effort. However, this could be difficult if the weights are worn out or the sash-to-rail connecting rail isn't properly covered with. This issue could be caused by a number of factors, including the lack of maintenance or an incorrect weight rating for a particular sash.

If the hinge arms on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To address this problem, first ensure that the sash fits squarely in the frame's opening and then remove it from the window. If the sash was attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).

Old windows, especially those in older homes, can be difficult to close and open because of sagging hinges and an overall inefficiency. In most cases, a few simple repairs can transform these windows into smooth operation for the first time and save the homeowner money on energy costs.

Sash Weights

Whether your window sash repairs are to replace a broken cord or to ensure that the windows are functional by replacing worn out weights for sash will improve its operation and cut down on energy costs.

When they fail, sashweights are often left unnoticed or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve It is therefore important to locate a new one that fits properly. You will also require an additional piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights to the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of these pegs have a large diameter on one side and a smaller one on the other, which is why it is essential to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife and mallets.

After the sash is removed then you can take out the sash stop and access the weight pocket. This is usually done via a small hole at the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the inner workings.

Be sure to weigh the sash before you begin, as the weights that were previously used may be a different size than the one you need.

Leave a few inches protruding at the head of the string to allow future adjustments.

Sash Cords

Over time these cords can break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in position when it is opened.

If the sash is still in place, pry the mortise-and tenon joints with a screwdriver or hammer and then take out each wood peg. The sash should move around freely now, however it may require some lubrication to make it feel less stiff.
