We moved into a Victorian house about 18 months ago. The (homebuyers) survey was excellent - no red or amber issues at all. Full of 'nothing negative to say about..' which surprised me in such an old house, but there was quite extensive rebuilding, re roofing etc in the late 90s.
The day we moved in I noticed the floor in the main bedroom undulates significantly. There are a couple of inches of drop towards the bay window of the living room below, and a large crack had been repaired under the window (covered by a long curtain when we looked around). We have just had an investigation by timber specialists and the main beam supporting the bay window and floor joists is rotten and needs replacing with a steel. We found some plans for restoration of the frontage drawn up by the previous owners' architect that states 'main beam very likely to need replacing with steel' so clearly this issue existed in 2012 when the got the plans drawn up. I have been advised the price will be some thousands and we will likely lose the beautiful original coving in the living room downstairs too :(
We are told we can't claim on insurance as a) it was like that before we moved in, as we saw the problem on the first day, and b) it counts as wear and tear/ failure to maintain.
Could we sue the surveyors though? Even though it was only a homebuyers survey surely they should have noticed a floor that was so significantly undulating?
