After removing the parting stops and trimming them to the desired length and thickness, apply a thin layer of double glazing repairers compound on the bottom of the sash. Smooth the compound using a putty tool, and let it dry for at least a day. Once it's fully cured, apply a top coat of acrylic latex paint.

Then, you can install the new sash (Photo 3).

Sash Weights

Whether your window sash repairs are to replace a broken cord or simply to keep the windows functional and functional, replacing worn-out weights for sash will improve its operation and reduce energy consumption. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and connected by ropes to the movable window sash. These weights function as counterbalances, allowing you to open and shut the window without having to use mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they fail. Consequently you may have to find replacements.

A weight in a sash that has fallen out of the cavity is difficult to get back, so you will want to find a new one that fits properly. You will also need a new piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that keep the components together can be removed by the use of a pin punch and hammer. The majority of these pegs have a large diameter on one side and a smaller diameter on the other side, so it is important to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be separated by using a knife or mallets.

After the sash has been removed and removed, you can take off the sash stop and access the weight pocket. This is usually done via a small hole at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inside workings.
