So the outside edge of the trim would be on intact dw but under the bulk of the trim the dw was smashed down.
Drywall extends past door jamb.
For areas where the jam was slightly short he would take a razor blade and score the drywall about 1 4 in from the edge of where the trim would sit then take a hammer and punch down the dw even with the jam.
I have a homeowner who has window and exterior door jambs that extend past the drywall by about 1 1 2 inches.
Not everything is perfect.
Door frame extends past drywall my issue now is trying to trim around the doors.
Step 2 use a 1 by 4 and cut the jamb extension.
As an amazon associate i make.
Measure at several spots on the doorjamb and use the largest dimension.
It s important to know what to do in less than ideal situations.
The door frame now sticks out past the drywall about 1 4 due to the old plaster being about 3 4 thick and the now the drywall is only 1 2.
