Hey everyone, first post - registered to ask a question to the community. I recently purchased a fiberglass pre-hung exterior door to replace the dented steel one that came with our house. The first install was a disaster - hung off-level/plumb, about 1/2" above the frame/sub-sill - so we had a second contractor come out and redo the install. Well, the second contractor shimmed the door on the bottom as well as the side/tops, about 1/4-1/3" higher than the old steel door was. I've attached some images - first image is the original gap, second is the first (botched) install, third is the newest install. Any insights from the experts would be appreciated.
