I have a couple solid core doors in my house that won't stay open. I have tried a tip of pulling the hinge pins and hitting them with a hammer. Any other known quick fixes?
sounds like the doors were not install plumb. #1 you can rehang the doors. #2 try bending the hinge pin a little more. #3 you can install a magnetic door stop, it goes on the bottom of the door and there's a small door stop that attaches to the wall or floor and the magnetic can hold the door open. that's all i can think of at the moment, i'm sure you'll get some additional ideas here.
