Handling storm-water runoff; refinishing hardwood floors.

Landscape contractor Roger Cook travels to Portland, Oregon, to show a homeowner an innovative way to handle storm-water runoff from her roof. In the ASK THIS OLD HOUSE loft, Roger is joined by host Kevin O'Connor, general contractor Tom Silva, and plumbing and heating expert Richard Trethewey to answer the question, "What is it?" Tom makes a HOUSE call to show a homeowner how to refinish her hardwood floors using a floor sander and water-based finish. (ATOH #610, 12/8/07, 1400-1430)
