Host Kevin O'Connor and master carpenter Norm Abram open the show at the most visited destination in the Nation's capital—DC's newly restored Union Station. Back at the project house, restoration contractor Danny Palousek has begun work on the exterior brick, while inside, general contractor Mahyar Mahvi shows Kevin the progress—the building has been insulated with expanding foam insulation, wallboard is going up, the stairs are under construction, and the new windows are going in. Norm meets millwork specialist David Baldwin at his shop in Millersville, Maryland to see how they are replicating new wood casings from originals found in the house. In the basement, HVAC contractor Michael Bonsby finishes installing the new high-efficiency, two-stage gas furnace. Although over budget due to items like the curved staircase and the additional powder room, project director Elin Zurbrigg feels she's still on track due to the 10 percent she set aside for overages.
