I had my front door replaced (wooden)recently because the old door seemed to be unlevel and it was the original door. 1951. I bought a new wooden door and casing.
It took 2 carpenters 11 hours to replace this door. They insist that it is level but the door doesn't sit in the frame correctly.
There is a large gap at the top and top left and it narrows at the bottom. Can this be corrected?
