We had a company round to take artex samples to test for asbestos and the surveyor said that he had to keep his shoes on. I was a bit apprehensive and said is he sure they're clean and he said yes because whenever he actually deals with asbestos he is covered up in a suit and over boots etc. I wish I'd been a bit more insistent though - all our results came back clear but I feel so worried about the fact that he walked around DCs bedrooms with his boots on - what if they were contaminated even slightly? My children (as with most) play on the floor. He walked everywhere in the house
