Sarah Beeny continues to investigate properties with extreme cases of problems like subsidence, damp, and dry rot. In this programme it's tree roots, which can pose a real threat to houses. Dave and Sharon thought they were stepping up in the world when they bought their handsome five bedroom Victorian property in Hull's Garden Village. They spent six months decorating it to the highest standard, but no sooner was the job done than massive cracks started ripping through their lovely new walls, and their windows started popping out. The family have been forced to move out in fear of the house collapsing on top of them. Sarah's convinced trees are the problem, but the local council doesn't want the trees to be cut down. Let battle commence.
