Our host visits a landfill engineered to accept hazardous waste, such as the asbestos off the side of the Gallants' house. Back at the house, Richard Trethewey helps Dean fix a leaky sink in the upstairs library, in preparation for setting up a temporary kitchen in the space while the old kitchen is demolished and rebuilt. Our master carpenter gives Dean and Lauren some help in removing the cabinets from the old kitchen, and they continue the job by pulling down plaster, lathe and blown-in insulation.
