Because of my cats, the carpet of my dining room is really in horrible shape. I live in a townhome. I replaced carpet on the second floor with bamboo flooring without too much mess since the underlayment there was only stapled to the subfloor. It seems that that in the dining room, it is glued down. I don't mind a little bit of work. But since my family has no other place to stay, I don't want to use anything toxic to get the underlayment off. Can I just use a scraper to get the glue off? My home was built in 1980. I don't know when the carpet was installed. Will asbestos be a concern when I remove the carpet and glue?
