Host Kevin O'Connor drives up to the house to find general contractor Tom Silva helping load up a truck for the "Building Materials Resource Center," a local non-profit that will be selling the project's surplus materials to needy homeowners at discounted prices. Inside the house, Tom shows Kevin the progress on the porch, kitchen, and master bath, where his crew is installing several new windows. In the basement, plumbing and heating expert Richard Trethewey gives an update on the mechanical systems. To learn more about the home's Milford Pink granite foundation being a sign of wealth at the time the house was built, architect Treff LaFleche takes Kevin to see how the same stone was used on the Boston Public Library, and also how the granite is quarried and split to best match the home's existing stone. Back on site, Roger installs the new Milford Pink granite, and also matches the old mortar.
