A few years ago I had two cracks in my basement foundation. I had several visits and quotes from contractors for repairs. I found that Martin was one of the most straight forward and reasonably priced contractor. They had to come back a few months after the initial repair as there was some water leaking through one of the cracks again. It was promptly fixed under warranty, but I am wary of the poly fill technique of sealing cracks as a result of the 2nd breach.
