The asbestos report on our house indicates traces of asbestos in the vinyl floor tiles used in the lounge. I suspect these were laid in the 70s but they are, apart from being a little grubby with old varnish, in good sound condition. I am reluctant to disturb them by lifting them and wondered if anybody knew if it was possible/safe to ceramic floor tile over them? Having said that the report also indicated 'traces' of woodworm in the grenier and when I went up there my foot went straight through the oak floorboards. We were able to negotiate a E2000 reduction in the asking price and it cost me E4000 to have the entire place treated. C'est la vie.
