What would you think if: the house is two years old, level lot, fair drainage, sandy soil, dry crawl space, no current signs of moisture infiltation. We have about 2 1/2 courses of cinder block foundation showing. the face of which is parged. 13 out of 15 standard metal foundation vents show a single vertical hairline crack in the block course immediately below the vent, at the vertical mortar joint joining the two blocks below. These same cinder blocks do show a crack on the inside face of the same block. Only one other foundation block crack is apparent, and that is located at a corner. Got any ideas as to what may have helped allow this to happen ?? Thanks, John
