The show begins at Nantucket's Old North Wharf, much of which dates from the early 18th century and site of several small cottages available for rent. At the site, homeowner Kathy McGrew Bentley shows us the window sash color approved by the Historic District Commission, as well as the outside placement of the chimney, which had previously been slated for inside the building. Contractor Bruce Killen describes the cost of the extra framing work so far: $30,000. Outside, mason Dan Kissell shows us how to parge the new concrete block foundation so that it matches the old foundation, while cedar roofer John Rex reveals the secret of the roof's decorative diamond detail. Out at Bruce Killen's workshop, Bruce helps refrubish the building's old fornt doors, using custom knives to replicate the moldings and a large belt sander to remove the paint from the frames. Finally, lighting designer Melissa Guenet and electrician Sally Kay Bates shows us the plans for the second floor.
