Landscape contractor Roger Cook shows a homeowner how to protect his ornamental shrubs from the ravages of hungry deer. Back in the loft, plumbing and heating expert Richard Trethewey answers a viewer's question about PVC pipe connections. Then Roger, Richard, general contractor Tom Silva, and host Kevin O'Connor try to identify unfamiliar objects in the "What is it?" segment. Afterwards, Tom heads out to help the Ryan family fix a shower door that won't close properly.
