No, that's not quite it.
I wasn't aware of the damage until it was very very serious, because it was only visible under my floor and above my suspended ceiling, and I wasn't lifting my floor tiles or taking down the ceiling every so often to check that nothing was happening. I became aware of the problem when water was dripping through the suspended ceiling. Me and a friendly contractor went upstairs to the flat above to find out what was going on and discovered that a junction between his bathroom sink waste pipe and his kitchen sink waste pipe wasn't connected - the pipes were at least 1" apart. The connection was sorted the next day.
Then there was a couple of months of crap from Zurich saying I should have been aware of the damage and they weren't going to pay because it was long term damage, even though it was invisible without taking down the ceiling/lifting the floor tiles, then they said ok they'd pay, then they said my estimates were extortionate, then their loss adjuster couldn't do an inspection in time so they used their approved contractor who they would have used to do the work and based my pay out on their approved contractor's estimate. Dodgy dodgy dodgy.
So eventually they paid up and I moved out and the work was done and I paid my guys and then put in a claim for my uninsured losses through Zurich's legal team, Beachcroft. Then Beachcroft said oh, but Zurich also insure the bloke upstairs so they'll just deal with it in-house. And now they're saying it's possible for the pipes to have somehow unscrewed themselves so the owner of upstairs isn't negligent so they're not paying and I should go back to their legal team to recover my losses from him direct.
Of course, what it actually comes down to is they were happy to pay out until they realised that a) it was expensive and b) they also insure upstairs so they have no chance of getting any of their money back, so they've made things as difficult as possible every step of the way. Because they are the excrement of fetid fleas on plague-infested rats.
