Riddled with rats, ants, termites, a possum and asbestos, Michelle and Steve's 1950's weatherboard house is a ticking time bomb. Building supervisor Chester shuts down the hazardous site and teams are evacuated as the asbestos is removed. Taking an entire day out of their schedule for the asbestos removal, the teams are way behind. Finally able to get back on site, contestants are faced with yet another problem: with all the walls stripped bare of the asbestos, the house has massive structural damage. The renovation has never been this challenging or teams this far behind. The teams are in big trouble.
