How to Replace a Window Sash Stop Molding389

A window sash stop molding is a thin strip of wood or metal that holds the window pane in place. Over time, these moldings can become damaged or worn, allowing drafts to enter the home and making the window less energy-efficient. Replacing a window sash stop molding is a relatively simple task that can be completed in a few hours.

Materials Needed* New window sash stop molding
* Measuring tape
* Miter saw
* Hammer or nail gun
* Nails or staples

Step-by-Step Instructions1. Remove the old window sash stop molding. To do this, use a putty knife to carefully pry the molding away from the window frame. Be careful not to damage the window frame or the glass.
2. Measure the length of the window frame. Use a measuring tape to measure the length of the window frame where the new molding will be installed.
3. Cut the new window sash stop molding to size. Use a miter saw to cut the new molding to the length of the window frame. Be sure to cut the molding at a 45-degree angle at each end.
4. Install the new window sash stop molding. Place the new molding in the window frame and nail or staple it into place. Be sure to countersink the nails or staples so that they are flush with the surface of the molding.
5. Test the window. Open and close the window to make sure that the new molding is installed correctly. The window should open and close smoothly without any drafts.

Tips* If you are replacing a metal window sash stop molding, you may need to use a drill to create pilot holes for the nails or staples.
* If you are not comfortable cutting the molding yourself, you can have it cut to size at a home improvement store.
* Be sure to caulk around the new molding to seal any gaps and prevent drafts.
