Overview: Facing major structural and water issues at the river house, Mike and MJ decide to take the whole house down so they can build it back up right. This is a major setback, and their profit will take a big hit unless they identify some areas to save. At the country house, they continue to solve the water issues but notice more water on the basement floor during a mechanical walk-through. MJ transforms the two-car garage into a functional and appealing workshop and living space.
