I noticed my front porch is starting to crack and seperate from the front of my home. Is this a sign that my house has a foundation issue ? Can this be repaired, or do I have to have a new concrete block porch installed. There are three pillars that run from my roof to the porch, but I am not sure if they are anchored beneath the concrete block or on top of it, causing it to be pushed down farther. . I attatched some pics for your viewing.
