I wouldn’t be overly concerned that the concrete cracked…it does that sometimes. Be concerned if you have heaving/unevenness in the support of your home. As others have said - contact a professional. I would suggest an engineer, not a foundation repair salesman…you get where I’m going with that - the foundation company will always suggest large-scale repairs. An engineer that has no financial dog in the fight will cost a bit but will give an hones opinion.
