Ways Of How To Replace A Sash Cord On Double Hung Windows Without Too Much Trouble
Thursday, May 27th, 2010How 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.
Stops or wood moldings attached to the jambs create grooves that a sash window uses to slide. In order to remove the frame you need to pry the parting stop and the inside stop from the jambs.
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.
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.
Sometimes these panels have layers of paint on them, you will need to chip the paint away to locate the screws that are keeping the panel secure. Once the panel is out, cut off any remaining cord. Feed the new sash cord over the pulley and down into the cavity that holds the weight until you can see it in the access panel. The new cord should be tied to the weight with a strong knot but not too bulky as it can bind in the window frame. Put the weight back in the cavity and put a knot in the other end of the cord allowing the weight to hang three inches above the windowsill when the window is in a fully raised 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.
