I had a French drain & sump pump installed in June 2013. The pump has a battery back-up so I don't have to worry if the power is out for a few hours. My basement has remained dry and odorless since the installation. Prior to the system being installed, I could never store anything in the basement due to the moisture and musty odor. I have been able to store items there with no worry about them absorbing any odor. I was happy with the crew who did the work and the office staff who, if I called with questions, answered them quickly and friendly. I am a HAPPY & SATISFIED Keystone customer.
