Please can someone advise? Our house sale is about to fall through today because our buyers got a survey done which showed that’s there was tree root damage to the drains outside under the drive way. Now they can’t get insurance on our house to exchange today because of the tree roots.
We’ve never had a problem with the drains and I suspect every house on our (tree-lined 1930s) road must have the same issue.
Has anyone ever had this? I’m just staggered that this issue is going to collapse the whole chain 
Apparently the buyer works in insurance industry and has disclosed the survey to everyone she has sought quotes from. Hence no one wants to take it on. Surely there’s a way to build in an exemption clause or something??
Ps. We’ve already discounted the sale price by the amount of the quote to get the drains fixed.
