After pulling up the linoleum to put down a tile floor a couple of years ago, I noticed a very small crack that runs all the way from the front to the back of this room (about 20 feet). More recently I noticed that the cieling sheetrock is developing a similar type crack in the exact same area. The floor crack is covered and the cieling crack is easily repaired with compound and some paint, but I'm wondering if this means that I may have a foundation problem? If so, what can be done? Thanks.
