Host Kevin O'Connor visits Suffolk Downs ? the oldest horseracing track in Massachusetts. Landscape architect Stephanie Hubbard fills Kevin in on some changes to the landscape plan, as the decorative trellises go up against the neighbor's garage. General contractor Tom Silva replaces the old, ivy-stained aluminum trim with new material. Homeowner Chris Flynn lends painting contractor Buzz Zimmerman a hand painting the walls in her kitchen, as master carpenter Norm Abram builds her a custom banquette at the New Yankee Workshop. Plumbing and heating expert Richard Trethewey shows Kevin the new PEX water supply lines, the automatic water shutoff in the third-floor laundry, and the custom radiator covers going in on the first floor.
