 then you absolutely would need a structural engineer to determine what the extent of the problem is and how to repair it. I don't know how old your house is, but in Delaware, builders are required to place a 10-year structural warranty on homes. So if that's the case, then you definitely need to give notice to the warranty company as well as the builder, not just the builder, but both the warranty company and the builder, so that there's a record of you making this claim inside that 10-year window. So I hope that that gives you some direction.
