My shower has been leaking so a plumber came and cut the board between the shower and the boiler pipe to check what cause it. We just moved in 2 weeks ago. My head was all about unpacking the boxes and the leaking shower. When the plumber was cutting the board I was right next to him and helped him to clean up after the the wall was opened and never thought there would be an asbestos. I am so worry now. The plumber is very young. He probably didn't thought about asbestos at all at that time too.
