The Copp family's small Waco apartment doesn't meet their two sons' special needs. That's where star footballer Tim Tebow comes in: He asked Chip and Jo to join him and his charitable foundation in creating a home that will truly welcome those little boys. The Gaineses have a property in mind, but it isn't ADA-compliant...yet. "I feel like if we put our heads together, we might be able to figure out how to make this house work for this family," Chip said. Teamwork like this requires a lot of players, and the Fixer Upper team—and the Copp family—are in for some surprises.
