I had a plasterer in to take down the old ceiling above my stairs and replace with new. Whilst he said there would be a lot of mess and that my carpets would be ruined, I assumed there would be dustsheets down & was prepared for a lot of dust but thought carpets should be largely protected so we were talking dust. Came home to find new fresh plaster all over the carpets. Wondered if anyone could offer opinion on photos as to whether carpet damage in photos should have been expected by me / would be possible if protected (as I am now told they were) or this is poor practice. Many thanks!
