After getting a couple of estimates, we are using Champion. They got us in the soonest and had a good price. Information-gathering, I learned that people sometimes put in french drains when they aren't needed. (If anyone wants to be bored by a description of why our house does need them, backchannel.) Recommended companies (besides Champion): Mariani and Richards Sisko Waterproofing (412-901-3091 <(412)%20901-3091>) - not used, but interviewed and liked Fountain Home Improvements - ditto
