Shimming Interior Doors That Slowly Open/Close by Themselves

I have two wooden doors that won't stay where I put them. One of them slowly swings to full open, the other slowly swings to fully closed. Both doors appear to be square in their frames when I look at the top and side edges of them.

Where can I find information on what to do so the doors stay where I put them, or can somebody give me a clue how to fix them?

 

I had a door in my basement that did the same thing (would not stay open). What I did is remove all three screws on one of the hinges and drove a 3" screw through the center hole. Then replace the other two screws. This pulled the hinge towards the jamb just enough to fix my problem. Which hinge (top or bottom) you work on will depend. Try one first then the other. If this doesn't work, then you'll likely need to pull the casing off one side of the door and try adding a shim here and there until that fixes it. Is your wall level? If not, your doors are probably swinging open and closed because they are not level. You'll therefore need to reset the doors entirely (hopefully this isn't the case).

 

I agree with mossman, put your level on the side of the frame (not the molding) and see if it is plumb. Most likely is not. Resetting it plumb should bring it back to normal action. Of course plumbing the sides in the flat direction is important, too. That is where you will need the shims and longer hinge screws.
