Host Kevin O'Connor arrives to find landscape contractor Roger Cook on site with the landscape apprentices from YouthBuild Boston. The group is helping to spread new soil in the front yard and also to plant low-maintenance ground cover and an ornamental dogwood tree. General contractor David Lopes shows master carpenter Norm Abram the progress at the front entry and in the kitchen of the second unit. Next door, countertop fabricator Danny Puccio shows homeowner Lanita Tolentino how to clean and remove stains from her new marble countertops. Finally, Richard and David Lopes install a new tankless hot water heater in the basement of Lanita's unit.
