I have a steel door to my balcony with an aluminum door sill plate that slopes inward. I can't tell if the house has settled oddly or if it was installed badly in the first place (the latter I think -- looks like the mason may have set the brick too high for the rough opening because the plastic weather stripping piece at the bottom of the door fits to the sill perfectly).
I wanted to try and reposition the sill plate, but I can't figure out how it's attached to the door frame. When I pry up the front and back it feels like it is attached about 1/3 from the front/outer edge.
Picture here:
Thanks.
