We just purchased a home and now that the snow level is not 4 feet high ( we live in central NY ) we see that the concrete patio/foundation has horizontal cracks, and crumbling along the side, corner and front wall of the sunroom that is visible. The other 2 walls are attached to the house. The back wall leading into the house is the original home exterior, the other side of the porch is also an exterior wall of the house. On this side of the front wall we can actually put our hand into the porch, the concrete floor and sunroom wall are not together anymore. I can not find any information online of others having this issue, is this something a contractor could fix or does it need to be torn down.
