I have a couple of doors in my house that drive me crazy. They both slowly close on there on volition. Can this be attributed to a common problem such as hinge alignment or jamb being out of plumb? Any help on correcting this problem will be appreciated.

 

Welcome to the forums! Several things can cause a door to open or close on their own. You hit on a couple, hinge placement and jamb attitude. Prior to making any adjustments, take a good level and see if the hinge side jamb is plumb in both directions, flat and on it's side. Open the door and take a plumb reading on the hinge side of the door with it open and half open. Now, if any of these readings give you the hint of being out of whack, removing the case molding on one side and tapping the door frame in the correct direction and renailing it could help.
Another thing to consider is the floor settling. Is the gap the same across the entire door at the top? If the gap converges in one direction or the other, then you have had settling and if feasible, a correction in the floor may be necessary.
Back to the top. If all your jambs are plumb in both directions, then the hinges may be misaligned. Determine which direction you want to move the door (usually out at the bottom if the door auto closes), unscrew the hinge from the jamb, insert a golf tee with glue on it into each of the screw holes in the jamb, driving them slightly with a hammer and cutting them flush. Now, you have a new jamb to drill and reset the hinge. Move it out slightly and drill one hole only. Trial and error may reap its benefits.
Post back if any of this didn't make sense or if you need further help.

 

Thanks Larry. I will do what you suggest and let you know how I make out.

 

If you have no success with adjustments, there are some lovely door stops available.

 

Hey, I'm a nail driver, and my bathroom door does this, and I use one of those capture type door keepers against the wall. Guess I should practice what I preach, huh?
