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.
