Question: are all 8x8 tiles asbestos?
Answer: If floor tiles were installed between 1920 and 1960, there's a good chance they contain asbestos because most flooring tiles manufactured during this period did. If the tiles were installed between 1960 and 1980, there's a slight chance they contain asbestos. The flooring tiles are 9-inch, 12-inch, or 18-inch squares.
