It's a long story, but we've just bought a house from people who, it's become clear in the last stretch, are pretty dodgy (not criminal, just wide-os who have done some dubious DIY and tried to scam us on extras). I don't trust them and I'm trying to get everything checked over before the seven-day period is up and it's too late to raise any claims against them. I've had gas engineers in (boiler needs replaced, they have deliberately loosened a pipe to make it work which has leaked everywhere) and electrician. Is there anything else I should get a professional to look at in the next four days? There was a survey done so I'm assuming things like the roof and communal areas are covered? What faults or problems have you discovered that you didn't know about when you bought a house?
