Slide in a doorstop.If you like to keep the windows open but hate the slams of interior doors, simply wedge a doorstop underneath the offending door. It’s a low-tech, logical solution that you can play up, using a decorative doorstop that adds a little zing to the room.
Check the hinges. Worn or improperly installed door hinges can lead to a slight imbalance, which in turn can lead a door to slam on its own. Open your door to a 90-degree angle and then set a level against the latch to see if the door is out of plumb. Tightening the hinge screws might correct the problem, but if the hinges themselves are worn, you’ll need to replace them.
