Okay so we bought this house about 1 1/2 months ago and all the windows have gaps or cracks between the window and the wall. On several of the windows, when I push out on the top corners the whole window moves, temporarily making the gap even bigger. It seems like if you push hard enough, the whole window is going to fall out of the hole in the wall it is mounted in. How do I fix this? Do I need whole new windows or can it be repaired? I called a couple window companies and was shocked when they all told me they wouldn't even come look at it because they only install new windows. I have no idea who to call to look at it. Thanks in advance.
