I just installed a replacement door. I leveled and plumbed the door, which brought it even with the exterior sheathing. However, the interior is a different story. the top of the jamb is even with the drywall. As I follow the jamb down, the jamb recesses about three eighths of an inch below the level of the drywall.
The question I have is what to line the moulding to. The drywall, which leaves the three eighths gap between it and the jamb, to be caulked. Or cut the drywall out, letting the moulding lay flat against the jamb.
Cutting the back end of the trim piece is not an option. If I cut only the part of the trim necessary to clear the drywall, I’d be left with less than an eigth of an inch (thickness) of trim.
