Then, take the sash from its holder and place it on a flat surface to allow you to reach all four sides.

To resolve 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 has been screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

The sash weights are usually disregarded or disabled by homeowners and turned into scrap when they fail; therefore, you may need to locate replacements.

Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to remove the wood pegs holding the components together. The majority of them have an enormous diameter on one side and a smaller size on the other, so it is important to remove the smaller-diameter sides first. Sashes that were made later in the century used glue instead of pegs. They can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised part loose using mallets.

After the sash is removed and removed, you can take off the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb.

Leave a few inches of space at the head of the string for future adjustments.
