My only negative is that they did not have an adequate dropcloth to protect our floors from the mud and gravel on their boots.
They did a pretty good job cleaning up the sump pit area. I still had to vacuum up some grit and clay.
I have a friend (Paul Reiden) who had this exact system put into his Neenah, WI home 3 years ago. He was happy with it and shared info on the system. I thought the info was first rate.
Great to work with. The crew that came to our house were great. Everything went just as planned...
