It seems that on the last several projects I've done the trim work on, the GC or owner calls me back about 1 or 2 doors rubbing out of about 20-25 doors. In each case, they were installed totally square and were not rubbing when I left the project and I left sufficient space for paint. They have all recently been pre-hung masonite hollow core doors with pine jambs. For most of them, I can just put in a full length screw in one of the hinge holes that goes all the way into the framing. I can't do this right when the are hung because most painters in the area remove the hinges and the doors to paint. Most of the hinges are really cheap hinges with screws that really aren't meant to be installed more than once and I find this may be most of the issue. Anybody else dealt with or dealing with this? I've noticed it more in the last year than in years previous and I've found the doors have not been built as well either (jambs too tight or too loose, etc). Thoughts on this? It is always the top corner of the door rubbing when it is closed so I generally put a screw into the top screw hole of the top hinge and it solves the issue or so it seems.
