After transforming the exterior of the Minnehaha House, Nicole Curtis turns her attention to the interior where massive plumbing and electrical problems lurk behind the walls. Construction cannot start until the 100-year-old wiring and piping are up to code, and that means the little Sheetrock that is up must come down. At the same time, anxious to get started on cosmetic work, Nicole restores antique exterior sconces, and works with restoration experts to repair the glass window for the grand front door. When the lights finally go on and the water flows, the walls go up throughout the house and Nicole completes her entryway restoration.
