Captain, all the procedures I can find for exorcism or banishment work on a rather personal level.
They are all psychosomatic approaches. They assume that the problem is not in the edifice, or the soul, but in the eye of the beholder.In short, you must be crazy, captain, but a good priest can help you work through it.

There may be ore or two sources I haven't consulted yet.
I'm happy to hear that.
