We have asbestos tiles in our kitchen. We had an inspector come in to evaluate whether they were safe or not. They said we could put some type of sealant on the floor and cover them up or we could have them removed. They recommended removal but it's a very serious project and the room has to be completely sealed off while the men with white suits come in a remove everything. In our case they would remove everything down to sub-floor. 12 x 24 kitchen, $3500. Needless to say, we chose the short-term solution and covered it. Good luck.
