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.

For a year and half, Nicole Curtis has been painstakingly restoring a 1916 mansion. Her plan is to build out the dark, dingy, old cellar, creating new living space that adds nearly 1,000 square feet to the home. A guest bedroom, full bathroom, laundry room and recreation area will be a major addition and a major selling point. Nicole goes for classic details like ceramic subway tile in the bathroom and hexagon floor tiles in the laundry room, but adds a fully plumbed wet bar in the recreation area. The end is in sight, but when Nicole discovers water pooling in the basement, she fears the worst. A costly problem at this point in the project could mean major delays that she just can't afford.
