Homeowners John and Molly plan to put the history back into their 1890s shingle-style home. They’ll remove ‘70s carpet, repair cracking balusters and transform the front entry, restoring the home’s original beauty and updating it for modern living. Jenn travels to Washington D.C. to see the Cherry Blossom Festival and then helps a homeowner select and plant a cherry tree for his own house; Mark learns about how Mount Rushmore was built and demonstrates various techniques for cutting stone; Nathan visits Abraham Lincoln’s house in Springfield, IL. Then, he helps a homeowner to replace his traditional mortise hardware with hardware that locks.
