Builder Andy Tiplady uses a less-expensive Brazilian hardwood called garapa for the new deck, and installs it with a hidden fastening system. Carpenter Chris Aguiar uses a jig to cut straight red cedar shingles into a wave pattern designed by the architect, then passes them up to George Duarte for installation at the top of the side gable. Inside, Andy shows master carpenter Norm Abram the progress on the flooring, which is four-inch strip red oak, and the simple details on the interior trim that will let the water views take center stage. Host Kevin O'Connor heads to Providence to meet designer Lisa Newman Paratore at her design shop to see her sense of style and what she is pulling together for the project. Back in Barrington, Norm meets architectural millwork specialist Mark White to see the decorative polyurethane brackets he's brought for use on the exterior, and he explains why polyurethane is a better choice than PVC stock for this application. In the second half of the hour, on ASK THIS OLD HOUSE, contractor Angelo McRae helps a homeowner tile his bathroom floor. Then, general contractor Tom Silva heads to Washington, DC, to help a help a homeowner weatherstrip her front door.
