Help, I need to know my rights here.
we’ve just had an extension built and knocked through. The plasterers have been in today and the existing floor is absolutely caked in plaster dust and dried on globs of plaster, plus there’s plaster dust all throughout the ground floor of the house. No attempt at all has been made to protect the floor, not a dust sheet in sight.
Reading online it sounds like it’s pretty impossible to get the dust out of wood floors although I’ll be over the moon if someone tells me otherwise.
We had planned to just extend the existing floor into the extension and I bought the new flooring for the new bit at the weekend. If I have to replace the whole area it’s going to cost £7k+ 
Where do I stand legally here? If it doesn’t clean up are the company liable?
