A door was replaced (due to break in). The contractor insisted to go to a bigger size door. So we went from 32 to 36 inch (which is more widely available). Now I see a gap of near 1 inch between door frame and what appears to be the stud near the key hole. The door is screwed with some long screws into the frame.
Is this OK?
What do I do with the gap?
1- Fill with foam
2- Try to fit in with wood. What wood type will not cause expansion and deformation of frame of door?
Also, near the door step I see newly exposed vinyl flooring in bad shape (something was covering this portion up before). What do I use to cover it up?
