Steps On How To Replace A Sash Cord On Double Hung Windows Easily
In order to know how to replace a sash cord you need to understand the basics of a double hung window. A double hung window has two sashes one on top and one on bottom. A sash is the framework that holds the glass. The sashes slide up and down within a window frame. The side frames are the jambs. Heavy metal sash weights connect to sashes with a rope-and-pulley system hidden behind the jambs. The weights provide a counterbalance that makes the sash easy to open.
A series of stops are attached to the jambs to provide grooves in which the sashes can slide. The stops that keep the frames separated and the inside stops can be pried off to remove a sash.
To begin this project, gather the materials and tools you will need to replace a broken sash cord. This includes new sash cord, a putty knife, a utility knife, finishing nails, a hammer, putty, paintbrushes and paint for possible touch-ups.
To gain access to the cord you need to remove the inside window stop from the sides of the frame. Position the putty knife at each nail holding the stop in place and slowly move it back and forth until you are able to pry the stop off. Be careful not to split the wood.
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.
Reinstall the frame, with the finishing nails secure the stops. You may need to fill in any gaps with putty and touch up any paint that chipped in the removal process. The project is now complete and you should have a window that once again opens easily. How to replace a sash cord is not as difficult as it may sound.
