This case involves a construction company that purchased a partially built house. The president of the construction company personally installed the water line to the house and then sold the home as complete to a homeowner, assuring him that the home was essentially airtight and waterproof. The sale contract included a 1-year express warranty against defects in materials and workmanship. When the homeowner received a much higher than average water bill, he initially thought this was due to lawn care in the springtime months. The homeowner’s next water bill even higher and he looked for evidence of a leak above the ground. When he did not find a leak, he contacted the construction company. The construction company dug up the water line and discovered that the main water line had separated from a coupling due to corrosion, creating a gap through which water was escaping. The water went underneath the foundation slab of the house and caused heaving, which resulted in cracks in the walls and uneven doors. The homeowner sued the president of the construction company for negligence claiming that he had negligently installed the plumbing.
