Ask This Old House

Landscaping contractor Roger Cook shows host Kevin O'Connor a few ways to deal with rainwater from gutters and downspouts. Then, up in the workshop, plumbing and heating expert Richard Trethewey talks "All About" pliers. Then Roger, Kevin, Richard, and general contractor Tom Silva ask, "What is it?" Afterward, Tom and Kevin insulate an attic floor using fiberglass batts and blown-in insulation.
