Plumbing and heating expert Richard Trethewey helps a homeowner with a smelly dishwasher. Then Richard, along with landscape contractor Roger Cook, host Kevin O'Connor and general contractor Tom Silva ask, "What is it?" Roger heads to Iowa to help a homeowner transplant a rose bush. Afterward, up in the loft, Tom shows Kevin the proper way to change a circular saw blade.
