Synopsis

Landscaping contractor Roger Cook demonstrates to Kevin O'Connor several methods for managing rainwater runoff from gutters and downspouts. Later, in the workshop, plumbing and heating specialist Richard Trethewey offers an in-depth look at pliers. Joining them, Roger, Kevin, Richard, and general contractor Tom Silva ponder a practical question: "What is it?" Finally, Tom and Kevin proceed to insulate an attic floor with fiberglass batts and blown-in insulation.
