I have a single hung vinyl window that I can't get to close all the way. The the building was built in 2007 and I assume the window is that old. Nothing appears to be blocking the track. Can this be fixed or should I look into replacing the window.
The window had a broken channel balance. I was able to order parts and replace both channel balances. I replaced both since it seemed like I should but maybe I could have just replaced the broken one.
