Hi Guys, I got three windows side by side by side, one window is 47" wide and the next two are 60" wide. The gaps between the windows are different also, they are 3-3/4, 6-1/2 and 2-3/4. My problem with these windows is that there is a 1/4" space between the window and the rough opening on the sides and tops of each window, right to the outside. These windows were installed by the previous owner, they are replacement windows only held in by one screw on each side, they are loose and feel as if they are going to fall out. I will provide some pictures later today but my question is what is the best way to fix them? I have done a bunch of research on the internet and this is what i found to do, I have listed those steps below. If anyone has any advise, tips or tricks I would greatly appreciate it! Steps: Remove windows, properly flash the rough opening and verify its level. Install exterior window trim that shrinks the rough opening by 1/2" all around the window Push window up against the new trim, center the window with shims and use two exterior screws on each side of the window to secure it. Use window and door foam to seal window from inside along with caulking on the seam of the window and wood on the outside. Thanks!
