Drywall extends past door jamb.
I have a homeowner who has window and exterior door jambs that extend past the drywall by about 1 1 2 inches.
Measure at several spots on the doorjamb and use the largest dimension.
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.
It is an old house 1920 s 2 story that had 2 layers of lathe and plaster on it.
So the outside edge of the trim would be on intact dw but under the bulk of the trim the dw was smashed down.
Tools used on this job.
As an amazon associate i make.
The ripped out the plaster and put in drywall and now all of the jambs protrude past the drywall.
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.
