Are the floors sinking in our house?
Our circa 1890 house is completely updated. We've only been here a year, and I've noticed that some of the tiles are cracking in the living room. Also, a wooden beam set in the middle of the floor seems to have shifted up (or the tiles around it down) about 1/8." Is this normal seasonal shifting (contraction/expansion with weather changes) or should I call a contractor? Thanks in advance for any knowledge you can share! (Additionally, I recently purchased a front loading washer and dryer set. Could the vibration -it's on the same floor- be causing this?)
