31x10 - This Old House

To replace the stairway he removed from the old kitchen, general contractor Tom Silva builds a brand new stairway to the basement. Then, plumbing and heating expert Richard Trethewey shows host Kevin O'Connor how to select a good quality faucet—discussing function, finish, construction and valves. Inspired by an existing arched door opening, Tom shows Kevin how he's making a vaulted ceiling in the hallway that connects the front of the house to the new addition out back. At the end of the day, insulation contractor Tony Trigler arrives to install spray foam insulation in the new addition.
