I removed carpeting and found old tiles in my 1950s home on slab. I removed all the floor molding and some of the tiles chipped away. I now suspect that the tiles contain asbestos and that I should not remove but just cover them. How do you suggest covering the existing tiles and repairing the space between the wall where the molding was and the space where the tiles chipped away before putting down my new wood floor. Thank you for your help.
