I find this all very strange. Even if the house owner has been offered a 'cash' closure on the matter there still remains the need to get walls and floors dried out, so someone must be getting the work through this route.
Got to say that even though I have a dedicated flood website (basic but it's out there) there's been no work coming from it. The last 2 'wet' jobs I have done have been thanks to a builder removing slates of a roof just as the week of rain started, and this job took only an hour as it had been a constant drip for 8 hours onto one patch of landing carpet, and the other was because of a dodgy connector on a water pipe between upstairs bathroom and down stairs living room, which eventually over the weekend brought the ceiling down.
So absolutely zero that relates to water rushing in through the front door!
