New series. Documentary following the work of extreme cleaners. In London, sisters Yvonne and Angela tackle the dirtiest flat they have ever encountered in nearly 20 years on the job, while Maxine and her daughter Jasmine deal with a hoarder who has 20 years' worth of possessions cluttering his home. In Somerset, Shaun and his team specialise in full house clearances and hey are sorting out a flat for a landlord, but the resident appears not to have thrown anything away in years and rotting household rubbish almost fills the rooms.
