The Process Of How To Replace A Sash Cord On Double Hung Windows Without Too Many Problems
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.
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.
Remove the molding on both sides of the bottom sash. Place your putty knife near each nail that is holding the wood in place and gently pry them loose. Practice patience as the wood can split easily if you try to rush.
Once the inside stop is removed the window can be easily pulled out. With the framework out, remove the broken cord from its fastened slot. Remove the access panel if there is one. Removing the access panel allows accessibility to the weight. If there is no access panel, removing the window casing on the sides will be the only way to get to the weight.
There are usually many coats of paint on these windows after years of use. Remove the paint to find any screws that are securing the access panel in place. Remove the panel and cut off any cord that is connected to the pulley. Feed the new sash cord on top off the pulley and into the crevice that holds the weight. Tie the new cord to the weight. Replace the weight and tie a knot on the end of the cord. Allow the weight to dangle three inches from the windowsill when the sash is open all the way.
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.
