Master carpenter Norm Abram takes host Kevin O'Connor on a ferry ride across the Mississippi River to Algiers Point, to see how the first This Old House New Orleans project, completed in 1990, held up during Hurricane Katrina. Back in Holy Cross, plumbing and heating expert Richard Trethewey shows Norm the plumbing layout and how HVAC contractor Raul Mena plans to heat and cool the house. Across town in Broadmoor, Norm and Kevin help install windows with the non-profit group Rebuilding Together. The group is renovating a house for wheelchair-bound homeowner Sonia St. Cyr at no cost to her. At Musicians? Village, founder Branford Marsalis shows Kevin around and introduces him to the youngest resident in the village, saxophonist Calvin Johnson, who joins Branford in a duet of ?When The Saints Go Marching In.? Despite debris at the jobsite, landscape architect Brian Sublette starts working with homeowner Rashida Ferdinand to draw up a plan for her yard and gardens.
