If your home has tiles that were installed between 1920 and 1980, there’s a good chance they contain asbestos. Unfortunately, asbestos tiles look like ordinary tile, so there’s no way to tell them apart by sight alone. However, if the tiles have started to come loose and you see thick black adhesive underneath, that’s a good indicator that the tiles may contain asbestos. If that is the case, get in touch with a professional immediately – do not attempt to remove the tiles yourself!
