The thing is, you can smell damp when you walk into somewhere, no matter how much air freshener someone’s used. Where I live, there are thousands of Victorian/Edwardian terraced houses and it’s well known that they weren’t built to the highest standards and they tend to suffer from damp. We looked round a few when we were buying and there were some where you knew there was a bigger problem the moment you walked through the door, because they smelt so fusty (or they’d reek of damp overlaid with Febreeze/Glade Plug-ins because they were trying to cover it up). I really don’t think this was all hidden and I just think they wanted the house and got caught in a bidding war. Anna has said it’s their forever home so maybe they’re just thinking that anything they spend, they‘ll get back eventually. I do think that ‘Super Project Man’ maybe hasn’t done his homework though and it’s a bigger job than they thought.
