Steve and Tom commute to the Charlestown job site in style - about Tom's boat. They arrive on site to find landscape contractor Roger Cook and his crew removing the massive granite curbing along the back patio and the old concrete steps at the rear entrance. In the process they unearth an old gravestone. Chimney specialist Mark Shaub gives a report on state of the home's four fireplaces and the staggering costs involved in getting them all to work. Steve helps Tom put in new floor joists, before taking viewers to visit one of the Charlestown's oldest residents, the Navy Yard.
