Austin green remodel project (Part 4 of 8)

Host Kevin O'Connor welcomes plumbing and heating expert Richard Trethewey to the "Live Music Capital of the World" with a visit to the legendary Continental Club - home of live rockabilly, swing and country music since 1957. The next morning, builder Bill Moore shows Kevin the progress and how sons Sam and David are helping out with demo in the first floor bath. Up on the roof, Richard finds solar contractor Andrew McCalla and his crew beginning to mount the modules that will make up a 2.45kW solar array providing 40 percent of the power needed for the new house. To keep the old house charm, Norm visits Brad Kittel at the largest salvage yard in Texas to find interior doors and glass knobs for the addition that will match what's already on the first floor. Plumber John Podolak connects the circulator pump for the tankless hot water heater, while out front, Bill shows Norm the problem with the sagging front porch pad. Concrete lifting contractor Ken Mongold provides a fix by injecting polyurethane foam under the slab to slowly lift it back into place. (Part 4 of 8)
