I recently had a new front door and doorframe constructed an installed in my Victorian terraced house. The old frame and door were ripped out, and a new frame and door installed. On inspection, I think that some of the work is well below standard, but I wonder if this is considered normal?
Which of these things are considered normal practice, and which things am I reasonable to complain about?
The top of the frame was left looking like this. Shouldn't they have replaced the whole frame?

The new sealant around the inside seems to have been applied by a novice in an extreme hurry:

The bottom of the frame looks a mess:

There are no mitred corners in the frame:

Where the ironmongary is sunk into the frame, it's not very tidy:
Added: This job was done by a professional contractor, for a decent amount of money.
