Tom makes a house call to Atlanta, Georgia to show homeowner Terry Andrews how to use masonry fasteners to install window boxes on his brick townhouse. Then Tom, Richard, Roger and Kevin ask, "What Is It?" Then, back in the loft, Richard shows Kevin several different ways to make copper pipe connections, including a new solderless system. Then, Roger helps homeowner Alan Lear of Carlisle, Massachusetts install a perimeter drain to catch rainwater running off of his roof.
