After a brief visit to the Brooklyn Navy Yard, master carpenter Norm Abram helps local builder Michael Streaman reinstall old interior door trim in the new library area. In Bensonhurst, host Kevin O'Connor finds countertop fabricator Alex DeMeo unloading a container of marble just in from Italy and the slabs of manmade quartz and resin being made into countertops. Later, the countertops are installed at the project house with cutouts for the range and seams made on site. In the basement, plumbing and heating expert Richard Trethewey meets electrical contractor Vinny Verderosa to see how the new service is set up for the three-family house. Then Richard meets local plumbing and heating contractor Randy Gitli to look at the mechanical room that contains two complete systems—one for the ground floor apartment and another for the top three floors. Upstairs in the master bath, tile contractor Mauro Zanutto shows Kevin his unconventional method for grouting the floor tile.
