I inspected this house this morning that had a slab front porch and a brick foundation. The brick foundation had a horizontal crack that extended all the way across. This foundation does bare the weight of the front roof that sits on a long header supported by 4 - 8"columns. The columns only appear to have a couple inches of the diameter holding up the header. The rest of the top of the column diameter is sitting exposed on the inside the porch and supporting nothing. I’m wondering if this whole installation of columns could be the culprit for the way the brick foundation has cracked horizontally all the way across the front. Any thoughts would be greatly appreciated.
