Despite both of their kitchens being gutted, aunt Chris Flynn and her niece Liz Bagley are still bunking in together in the upstairs unit, getting by with just a refrigerator and a hot plate in the dining room. Kitchen designer Kathy Marshall shows Kevin and Liz two possible schemes for Liz's new kitchen in the first floor apartment. Master plumber Bill Kane shows plumbing and heating expert Richard Trethewey a new pipe relining system that will line the old cast iron sewer pipe lateral with a new, continuous pipe made out of resin to protect against future tree root infiltration. On the second floor, host Kevin O'Connor lends general contractor Tom Silva and master carpenter Norm Abram a hand hauling in and installing a new carrying beam that will allow for an open floor plan. Master electrician Allen Gallant shows Kevin how he's snaking new wires through the old walls using a fishing system and a flexible steel drill bit
