The perennially pregnant Sarah Beeny continues to rescue families from the most 'horrific problem properties ever imagined.' This week, Paul and Clare bought their house in Essex as the perfect home for their four children, but peeling back the wallpaper revealed a terrifying crack along the back of the property. It turns out their dream home is sitting on six metres of sludge and it is tearing the structure apart. If that's not enough, there's a rat infestation, sewage seeping into the ground floor, and black mould that is making the kiddies ill. Can Sarah turn this disaster around and help this family get a safe and beautiful home at last?
