If you need a contractor to fix a foundation wall, the question is why? If you want names and numbers of contractors, I have plenty as well, but my bigger question is what caused the need for repair? What is the cause of this problem with the foundation wall? Do you need information from a structural engineer as to the cause and repair required?
You can get someone to slap some filler in the cement but is that the solution? I would hire someone specifically skilled in the solution to the CAUSE of the problem.
Hope that helps and let me know if you need some names, depending on what the 'fix' needs to be.
