We just did a basement dig out and installed a new (thick) foundation -- I need to find a fiberglass exterior door that fits a 12.5" jamb (twice as thick as normal jambs). The door swings in, so I'm told simply putting in a jamb extension isn't a great option in terms of maximizing door integrity and weatherproofing. I also need a threshold that spans this depth.

Various door companies are telling me that it is impossible to find a door that has that thickness and my contractor is saying that he isn't able to make a threshold that deep since he doesn't deal with metal work. To possibly further complicate issues I am also looking to get all hardware/metal to be in antique bronze (not silver).

Does anyone have any suggestions?? I doubt I am the first person who has run into this issue of extra deep jambs for interior swinging doors and would be grateful for any advice. Thanks in advance!
