I have a 1966 rambler and the basement rec room has vinyl tiles. I had sump pumps put in. The company pointed out that the tiles and mastic might contain asbestos, assured me that they were experts in dealing with this, and then as far as I can tell took no special abatement steps at all. Instead, the company jackhammered up a broad band around the room, laid in the drainage pipe, and then cemented it over. They meticulously evened the cement to be even with the rest of the cement floor - which means that it is about 1/8 to 1/4 inch below the level of the top of the tiles. Putting aside for the moment the possible health risk to their workers and to us home residents, I now have an uneven floor with a lower band of cement around ancient vinyl tiles.
After thinking about various possible flooring surfaces, I thought a nice laminate might be a good idea. However, I am concerned that the uneveness will result in project failure (and possibly void the warranty). There are two possibilities that I see: removing the rest of the tile, or using a leveling compound around the perimeter of the room to get everything level to the top of the tiles before laying laminate. I read an interesting post by someone who popped off ancient vinyl tiles by putting blocks of dry ice on top of them. Others have said that leveling compound is difficult to work with and the job requires two people.
Which way would you go? Would you a) do it yourself, b) try to level or try to remove the tiles, c) give up laminate and do something else? Thanks.
