The floor tiles have been removed a month ago. The dehumidifiers are on for the last three weeks due to next door's burst pipe. Air test was done and visual inspection report after tiles removal shown satisfactory. But this morning whilst checking around the room I noticed there are quite a few broken pieces of tiles left underneath the skirting board, a plank of word and a big piece inside the radiator! I am so concerned, especially with the dehumidifiers on. Please I need someone to calm me down! What are the chances of releasing danger fibres into the air with broken tiles?
