Suggestions On How To Replace A Sash Cord On Double Hung Windows Without Too Much Difficulty

How to replace a sash cord is a lot easier when you understand the mechanics of a double hung window. Every double hung window has two sashes, the top and the bottom. The frame that secures the glass is a sash. The sides of that frame are the jambs. Sash weights sit in back of the jambs. They are connected to a cord pulley system. The weights keep the windows balanced and easy to open.

There are a series of moldings along the jambs creating channels for the sashes to slide. The piece of wood that separates the upper and lower sashes and the one that holds the bottom sash in place can be easily loosened and removed. They need to come out to remove the sash.

Before you start this project, make sure you have the correct tools and material readily available. You will need new sash cord, a putty knife, a hammer, a utility knife, putty, finishing nails, paintbrushes and in case you chip away the paint, enough paint to touch it up.

Take the stops on each side of the lower sash off. Using your putty knife, place it close to each nail that is securing the stops and pry it gently away from the frame. The wood splits easily so take extra care to work patiently.

With the stops removed, the frame should come out easily. Remove the damaged sash cord from its slot. Most sash windows have an access panel to get to the weight. The access panel will need to be removed; if there no access panel then the side window casing has to be taken out to get to the weight.

Painted over access panels will mean chipping the paint to determine where the screws are that hold the panel in place. You may need to score painted edges with the utility knife in order to lift the panel out. Once the panel is removed, any remaining cord should be cut off. Thread the new sash cord over the pulley until it appears in the access panel. Tie the new cord to the weight making sure the knot is sturdy but not bulky as it can get stuck in the window frame. Place the weight back into the cavity. Tie a knot to the other end of the cord to make the weight suspend three inches above the bottom of the sill when the sash is in an open position.

Replace the framework and insert the moldings using finishing nails to secure them. Fill any gaps in the moldings with the putty. Paint any chips in the wood. The project is complete and your double hung window should work like new.
