The show begins with a visit to the Wharf Rat Club, a collection of old-timers who gather to chat each morning in a former quahog-sorting shack on Old North Wharf. Then we check out the progress at the house: a Victorian-detailed chimney is complete,... (more) as is the custom bulkhead door. Inside, general contractor Bruce Killen goes over the features of the newly arrived windows - wood construction, factory-applied two-color paint scheme and exterior trim, interior energy panels, vinyl sash guides, tilt-in cleaning, excellent weatherstripping - and we see one go in. Then we meet energy conservation specialist David Weitz, whose company is using a three-part system - foam, high-density fiberglass batts and extra-tough vapor barrier - to bring This Old House up to the highest of insulation standards set for new housing. At the workshop, our master carpenter finishes off the exterior brackets by making intricate decorative in-fill on the bandsaw.
