Teacher Andrew Hartley from Kent has a small problem with mould behind his washing machine. His brother recommends a tradesman to fix it, but it is Roger who makes the house call. Using smelly cheese and a bottle of water, Roger tries to con Andrew into a damp-proofing job he does not need. Will he pay up?
Plus Andy from Surrey is set up by his wife, who creates a puddle of water and blames it on the washing machine. Roger has various tricks ready to con the consumer, but could Andy turn out to be his toughest challenge yet?
Also, victims of rogue tradesmen in Nottinghamshire discuss how they were taken in by unnecessary roofing and damp-proofing work. The gang responsible pocketed almost 1.5 million pounds from 200 consumers, and were cornered after a mammoth five-year investigation by Trading Standards.
