The 35th celebration season of THIS OLD HOUSE begins in Boston's oldest neighborhood: Charlestown. The new project is part of a cluster of 1850s-era Greek Revival houses tucked into the backside of Bunker Hill. Homeowner Angela Daigle shows Kevin the outdated kitchen she'd like to improve. Upstairs, Tom shows Norm the spaces needing minimal work. The third floor will likely be a full gut to give Angela a better master suite with additional living space, assuming the city approves the plan to enlarge the existing dormers. Out back, Roger shows Kevin the crumbling retaining walls. In the second half of the hour, on ASK THIS OLD HOUSE, Richard showing Kevin some solutions for dealing with rust staining. Tom opens up a small home by installing a pass-through in a load-bearing wall. Roger replaces a poorly built fence gate with one that will last. And the guys play "What is it?" with special guest NASA astronaut Rick Mastracchio.
