Landscaping contractor Roger Cook helps a pair of homeowners improve the appearance of an unsightly concrete retaining wall with wooden lattice and climbing vines. Then Roger, along with plumbing and heating expert Richard Trethewey, general contractor Tom Silva, and host Kevin O'Connor ask, "What is it?"
