Hi, don't know if I am in the right spot but here goes....I live in Cincinnati and weather now is about high 50's to low 70's. All of a sudden three of my interior doors don't want to close, like they have suddenly expanded and are too big for frame - frustrating because it is door out to garage which is letting cold air in and a bathroom door downstairs and a bathroom door upstairs so privacy is tough these days. Why is this happening? Is it weather or humidity related and what can I do?? Dont want to lose all my heat to garage and want to potty in private!! Please HELP!!! thanks!!!!
