I've got a lot of windows that won't close all the way, and that have broken locks. Not sure if they're crappy windows or not -- the previous owner cheaped-out a lot of things.
Anyway, how can I fix this? It seems like it should be easy to replace the locks, but a lot of the windows won't close enough for the locks to work, and I think that's why they broke.
Another question: what do I even call this problem? Not sure what to google. Are these "sagging"?
