Understanding Sash Windows

Before we dive into the process of replacing sash cords, it's essential to understand the different parts of a sash window.

Sash

A sash is the part of the window that moves and slides up and down. Most sashes are divided into two or more sections, which are held together by a vertical bar called a muntin.

Cord

A sash cord is a rope that runs over a pulley at the top of the side jamb and anchors to a cast iron weight. It controls the movement of the sash, allowing it to move up and down.

Weight

The weight is a cast iron object that is attached to the sash cord. It counterbalances the weight of the sash so that it can be moved up and down.

Bead

The bead is the strip of wood that runs around the edge of the sash. It holds the sash in place inside the frame.

Staff Bead

The staff bead is the strip of wood that runs along the inside of the window frame. It holds the sash in place and covers the cavity where the weights are located.

Frame

The frame is the structure surrounding the sash window. It keeps the window in place and supports the weight of the window.

How To Replace Sash Cords

Now that you understand the different parts of a sash window, let's take a look at the steps involved in replacing the sash cords.

Step 1 Remove the Sash

The first step in replacing the sash cords is to remove the sash from the frame. To do this, you'll need to remove the bead that is holding the sash in place. Use a flat pry bar or chisel to carefully pry the bead away from the frame. Once the bead is removed, you can gently lift the sash out of the frame.

Step 2 Remove the Old Cord

With the sash removed, you can now access the old cord. Locate the cord at the side of the sash and gently pull it out of the pulley. If the cord is old and worn, it may snap, so be prepared to have a replacement cord ready. Once the cord is removed, you will need to detach the weight from the cord by removing the knot.

Step 3 Replace the Cord

With the old cord removed, it's time to replace it with a new one. Cut a length of new cord that matches the length of the old cord. Tie a knot in one end of the new cord and attach it to the weight that you removed in the previous step. Thread the cord over the pulley and through the hole on the side of the sash. Tie a knot in the other end of the new cord.

Step 4 Replace the Bead

Once you have replaced the sash cord, it's time to replace the bead that holds the sash in place. Carefully position the sash back into the frame, making sure that the cord is threaded through the pulley and tied securely to the weight. Gently tap the bead back into place using a hammer and chisel.

Step 5 Replace the Parting Bead

The next step is to replace the parting bead, which is the strip of wood that separates the two sashes. Use a pry bar or chisel to carefully remove the old parting bead. Cut a new piece of bead to match the length of the old one and gently tap it into place using a hammer and chisel.

Step 6 Replace the Lower Sash

Once the parting bead is replaced, it's time to replace the lower sash. Repeat the process of removing the bead, replacing the sash cord and weight, and replacing the bead. With both sashes replaced, your window should be fully functional.
