Hey, I got the same concern with you as well. I recently bought a 2nd-hand house near to my parents house. We have been living there nearly 30 years and now only I realize the ceiling is asbestos ceiling. Can I know what option you took in the end? My parents claimed all the houses built in that era uses this kind of ceiling. And if it is hazardous, many people will kene already. Hopefully that's only I am too worried about this...
