When you pick Otto Wilkens for a contractor you shouldn't do it because you're looking for a deal. It's unlikely he's going to be the cheapest, but you're going to get value, honesty, integrity, and something I appreciate throughout any home reno process - good communication.
Otto took care of a piece of concrete in the front of our house, and we're very happy with how it looks and how the whole process turned out. Definitely keep Wilkens in mind if you're doing concrete or masonry work done.
