This might be a bit long so apologies in advance.
About 18 months ago we had a fire at our house - it was not caused by us but by a workman. Our insurer arranged a builder to put right the damage, which was substantial and involved replacing the whole roof of the property plus a load of other things internally. The costs of this were eventually met by the workman's insurer as he admitted liability.
We live on a terraced street and our neighbour on one side is now claiming that in the process of the builder replacing the roof, part of his property has been damaged which he now wants to be put right. We have told him to address this to the builder directly but the neighbour is adamant that the responsibility for putting the damage right lies with us and he is now threatening us with small claims court.
IMO he does not have a case. Firstly he would have to prove when and how the damage was caused which I think he will find impossible to do (it could have been caused by the fire, by the builder or by the scaffolder, or indeed it could have been there before the fire happened). Secondarily, if he can establish how and when the damage was caused (eg: that it was definitely the builder that caused it) then he would surely need to go after the builder directly rather than us.
Does anyone have any knowledge of this area of the law who could advise me whether we need to be worried about being summoned to small claims? I am 95% confident we are in the clear but it would be good to know for sure!
