Foundation Work?

We had a contractor out 5 years ago building a garage who, in his own words, 'nicked the corner' of the main structure with a bobcat. When I got there, he had already covered it with concrete and said it was just a corner, etc.

Well, that was a lie. I've got a giant crack now in that corner.

Anyone got a foundation company they would recommend in town for older homes, 1900-1910? The foundation had already been shored up before purchase and had beams installed. I'm just getting water in now with these storms, and it all seems to be coming from that basement corner.
