Donna and Toni live a few houses down from Toni's childhood home. They love the family-friendly neighborhood, but need more space for their three-year old twins. The solution: a second story dormer addition that will accommodate three new bedrooms and a master bath. Once they demo the walls of the existing structure, their contractor will complete the exterior shell. Then, they will frame the upstairs bedrooms, tile and install bathroom fixtures, and lay new hardwood floors. But an unforeseen complication threatens to delay their project and inflate the budget. Will this family save 10 grand or have to put the power tools back in their contractor's hand?
