Help! My House is Falling Down

Can Sarah help save a 14th-century Essex farmhouse from utter ruin? Andy and Andrea Green are at the end of their tether with their home's leaking roof, the cracking render, rotting beams, and a dangerously decayed bathroom floor. The 500-year-old house has been in Andy's family since 1908. Can Sarah can offer a solution? With timber specialists, roofing experts and plumbers on site, the results show terrifying problems: a deathwatch beetle infestation and impending structural failure in the cellar beams.
