After the sash has been cleared, you can install parting stops. These are long pieces wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you can also replace them with scrap wood.

After removing the stopper and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash.

If the hinge arms of a window begin to slide, this could cause the sash to slide and eventually land on the frame in the corner opposite the hinge arm (Photo 1). To remedy the issue ensure that the sash is centered in the frame opening, and then take it off. If the sash is fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Sash Weights

Whether your window sash repairs are to replace a broken cord or just to keep the windows functional and functional, replacing worn-out sash weights will improve sash operation and help reduce the energy cost. Sash weights are hefty lead or iron cylinders, which are enclosed inside a hidden compartment and linked to the moveable the sash with rope. They function as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners, and are turned into scrap when they break; therefore you may have to search for replacements.

A sash weight that has fallen out of the cavity is difficult to get back, so you will want to find a replacement that fits properly. You will also require an additional piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.

Most of them have a large diameter on one side and a smaller size on the other, which is why it is crucial to take out the smaller-diameter ones first. Later sashes used glue instead of pins. They can be cut by using a knife or mallet.

After the sash is removed, you can remove the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inside workings.

Once the sash is stopped and the access panel has been removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash first because the weights you've got may not be the correct size. Once the new weight is installed you can tie a string around it and then thread it through the pulley of the sash.

These are often wedged in or nailed in, but they can be prised free, so it's worth taking your time. If the sash remains in place, pull the mortise and tenon joints free using a hammer or screwdriver, then remove each wood peg. It should now be possible to move the sash around freely, though it might require lubrication if it feels stiff.
