In fighting some recent leaking issues, I've discovered that my window well are not attached to the foundation. It's a steel window well. It's fairly snug against the house, but I can wiggle it fairly easily and I can tell the top few bolts are missing.
1) Do I need to attach this to my house, or can I leave as is? Could it be contributing to filling my window wells when it rains?
2) How do I attach to my foundation? Are there large lag screws? Do I need to put anything between the cover and the foundation?
