After weeks of intense planning, Extreme Makeover: Home Edition kicked off on Wednesday at 8 am as Ty and the crew showed up to greet Andy and Heather Cowan, residents of Bunker Hill, Indiana, with the news that they were the recipients of the life-changing event.

The family’s home was contaminated with mold that caused problems for the children, especially Kori, who has a congenital blood disease. “I just hope that you understand that you guys have saved our family,” Heather said. “It’s not about the house, this is a lot bigger than the house.”

The Cowan-Brown’s will be travelling to Disneyland while the “Extreme Makeover: Home Edition” team rebuilds their house.
