Frank asks Tommy for help with the leaky parapet at the front of the house. They find the parapet is filled with dirt. After removing it all, they use a rubber roofing material to properly seal the roof and prevent further leaks. Kevin heads to nearby Dearborn to tour the sprawling estate of a famous automaker. After decades of wear and tear by various owners, the mansion is finally getting a much deserved makeover, using preservation techniques to preserve the history throughout the home. Back at the house, Kevin and Tommy work with Frank and his friends to demo the kitchen walls and investigate whether a beam is needed to open up the room. At the Grandmont Rosedale project, a large tree looms over the house, with a root system that threatens to compromise the foundation. Kevin speaks with removal contractor Rick, who explains the process of taking it down.
