Kate and Greg hired a contractor to install a French drain and bathroom with a bathtub in their basement. When they came home to see their walls were sliced along the bottom and the contractor duct taped them back together, they quickly kicked him off the job. Now they are left with no place to bathe their son who is getting too big for the kitchen sink, and a hazardous situation with exposed wiring and insulation right at their child's eye line. JD comes to their rescue and discovers the situation is much worse than Kate and Greg thought. Not only is everything the contractor did wrong, but he also missed a glaring mistake - damaged asbestos tiles right on the laundry room floor. JD and his team leap into action and give Kate and Greg the basement of their dreams.
