General contractor Tom Silva helps Chicago-area homeowners Daryl and Catherine Katauskas repair their exterior door jamb by installing a dutchman. Back in the loft, Tom, plumbing and heating expert Richard Trethewey, landscape contractor Roger Cook, and host Steve Thomas examine two unfamiliar objects and try to guess how they're used. Then Richard prevents a basement from flooding by installing a leak sensor and automatic water shutoff valve on a water heater.
