We are remodelling a bathroom that has small 1/2 inch tiles on the floor. They appear to be laid on top of what looks like concrete. Some of them around the edges are coming off easily (we just got done removing the walls). Do you think it's okay to just take a cold chisel or something like that and go ahead and chink them all off and then retile? Do we have to worry about asbestos? Or should we leave the tiles on and tile over them? (We're having someone come in to remove the toilet, sink and tub.)

Any comments or suggestions would be much appreciated.

You didn't mention whether the house was pier and beam or concrete slab. If only a few tiles have come up on the floor, you can reset them. If it is amajor problem or if you just want a new floor, remove the tiles with a cold chisel. Most tilework done in the mid-fifties and before was on a full mortar bed (1.5 " or more thick). You can thinset new tiles on an old mortar bed if it is sound. After removing the 1/2" tiles check the mortar bed for cracks or loose pieces. If sound, install new thinset tile, if not, remove the old mortar bed. You can install a new 1.5"+ mortar bed or build up the floor with premanufactured 5/8" cement backer board and then install the new thinset tile.

There should be no asbestos in the mortar or tile.
