Chip and Joanna don dust masks in preparation for demo day on one of their most ambitious Fixer Upper undertakings ever.

This 100-year-old colonial was beyond run-down. It was badly water damaged, critter infested, and would prove to be one of Chip and Joanna's most challenging renovations.

This 'before' shot of the kitchen conveys the basic idea behind nicknaming this house "The Beast" and is representative of the overall state of the property before the reno.

Joanna and Chip pose for a pic outside the front entrance of the home prior to the renovation. Aside from the heroic scope of the project, this renovation was particularly special for Chip and Joanna in that, in this case, their clients are also their friends and work associates, Clint and Kelly Harp.
