I have a interior door that if you open it just a little it will swing all the way open on its own. How do I fix it so it will stay at the position I want it to be open.
Two ways. You can go through all the steps to make the door as plumb and perfect as possible, OR, remove one or both of the hinge pins from the hinges and slightly bend them, creating friction that will hold the door in whatever position you set it. We can elaborate more for the method you choose. :)
