Laying Sod In The Backyard/Installing A Wireless

Landscape contractor Roger Cook helps a homeowner lay sod in his backyard. Then, Roger, along with host Kevin O'Connor, plumbing and heating expert Richard Trethewey, and general contractor Tom Silva, asks, "What is it?" Afterward, Tom shares a tip about finding measurements without doing math. And Richard installs a wireless thermostat to control a heating system.
