how to replace sash cords in old windows
I own a house built in the 1930’s in Baltimore and need to replace the sashcords in some of the windows. Friends of mine have tried unsuccessfully to do this without removing the trim from the windows and they have really made a mess of their project. My brother who does construction is coming from out of town to do this for me. However, he has no experience fixing sashcords in windows (frames an excellent house, though so he is experienced at working on other aspects of construction).
My question is this: where can I go to learn how to fix the sashcords while doing the least damage to my house/ walls/ windows? There is no plate in the side of the window that gives me access to the point where the cord connects to the window.
