Our host meets landscape contractor Roger Cook as he and his crew install a plastic drywell in the cramped space next to the garage. Homeowner Dean Gallant insulates beneath the kitchen floor, using breathable poly-wrapped insulation, which is easier to handle than the unwrapped product. In the kitchen, the crew has insulated both the exterior walls and some interior partitions (for sound transmission reduction) and put up a tough, cross-laminated vapor barrier that won't rip during the rough and tumble of drywall installation. At the rear of the kitchen, our master carpenter puts in the new back door. We meet historic interiors expert Susan Hollis, who is advising Lauren Gallant as to the proper Arts and Crafts-style wallpapers and lighting fixtures to use. Finally, our host visits the stained-glass workshop of Peter Mattison and Charles Billings, who are repairing the damaged windows from the Gallants' house.
