My house settles in various ways depending on the time of year and the weather conditions. Right now, it's causing something it's never done before and I don't know what to do about it. My French doors are not catching when they're closed, and it's almost impossible to lock the deadbolt. Just FYI, the French doors are double, both sides are actual doors, but one side is always kept locked in place. I've been shoving some wadded up paper between the top of the door and the frame, and that's doing an okay job of pushing the door down slightly enough so that the doorknob catches. But it's a hassle!
My main concern is that the door will accidentally/unknowingly be left 'open' and my cats (strictly indoor) will get out. The door has to be opened many, many times a day because that's the only way for my dogs to go out into the backyard to potty!
Any ideas will be greatly appreciated.
