My husband and I are trying to install a new door between our kitchen and garage. We purchased a prehung steel door with an insulated core. Because the door came with no instructions, we made the mistake of taking the shipping braces off and allowing the door to open before we installed it. Now I think it is just not square. We hung it once, but it was hard to open and close. The top half of the door's edge was hitting the frame as well as a little bit at the very bottom. We took the door out again and stood it on its side to try and make sure the door frame was square and place the braces that hold the door closed back in place. The door frame is now level (after being shimmed on one side), but the door still sticks when we try to open it. The door itself is very close to level, but not quite (when open).
Also, our home had some minor foundation problems three years ago near where this door is located. (I have a call in to the foundation company to come and check it again.) When we removed the trim from both sides of the old door, there was a larger gap on the left than the right when facing the door and looking between the top of the door and the drywall. The new door is like that too. I thought it could just be that the hole in the drywall is cut crooked.
The door is better than the first time but is still hard to open and close. Can we just and down the door's edge so that it will shut properly, or do we need to completely remove it and start again? Any suggestions will be greatly appreciated!
