Chimney specialist Mark Schaub meets up with host Steve Thomas in the Winchester living room and shows him why the chimney is smoking, with the help of a diagnostic ""fluecam."" In the kitchen, general contractor Tom Silva shows master carpenter Norm... (more) Abram and Steve how he reinforced the framing of the kitchen addition with engineered lumber and steel. Recalling the issue of the cantilevered second floor, Steve takes a look at a major renovation of perhaps the most famous cantilever in the country, that of Frank Lloyd Wright's Fallingwater. Back at the project house, Steve lends Tom and Norm a hand on the deck structure for the new sun porch.
