Vulcan Basement Waterproofing was great. They did a gravity drain for the length of my basement, and pulled that trench into a sump pump. As of yet, I have not had any water issues in the basement. So far, it's been really excellent.

They called just recently and came and did a regular check-up too. I was worried because I never heard the sump pump come on, but they confirmed that it was working. I thought that followup was excellent.
