My husband and I are first time homeowners and bought a house that was built in 1960 and not really updated since then. We pulled up carpeting downstairs to uncover a linoleum floor which I believe is on top of a concrete slab, as the room is adjacent to the garage. I suspect that there is asbestos under there so we don't want to pull it up but we figured we could install a floating floor over it. While I was cleaning and patching up parts of the wall, I discovered that one tile that is the last one next to the wall of the garage is slightly higher than the rest. I was wondering how this would affect the flooring, if at all. Is there a way we could level just this one part out before we begin? The rest of the floor is in good shape so it's really just this one tile that would be an issue. Since it's along a wall, there won't be much foot traffic on it, if any, and the room itself isn't in a high traffic area of the house.
Thanks for any and all advice on this!
