The basement guys were skilled at their jobs. In that sense, the experience exceeded our expectations from salesman Kevin. They were able to install drainage tile beneath the floor clear back behind the toilet, water heater and furnace and into the next room. Outside, they were able to tunnel beneath the central A/C unit. These are all areas Kevin said they would probably just go around. Considering the area behind the toilet was one of the biggest problem areas, we were very happy to see that had been done so well, both inside and out. The guys were very skilled at what they did.
