I have recently added 6 new windows to my house (new holes in the walls). I have also purchased 13 additional new construction windows to replace the old wooden ones. I know the process of replacing them; however, up to this point I have always had an extra set of hands with me. I will have a large chunk of time this weekend to install at least a few windows, but the guys are all unavailable (coincidence?). I would like to at least take a shot at doing the smaller ground level windows.
Question: Are there any techniques or processes that could help me in my endeavor to install these new construction windows by myself? My main thoughts are around centering and maintaining appropriate gaps (specifically top and bottom) without having someone on the inside.
I know, silly question, but hoping someone has a tip or two.
