Should you Tile over Tile that has Mold Growing Underneath it?

By Mark J. Donovan

Question: My basement got water in it and I know I have mold growing underneath it. I am in the process of putting new tile over the old tile and am wondering if this is the right thing to do. I am wondering now if I should remove the old tile before installing the new tile. Any help would be appreciated.

Answer: Mold can cause negative health effects to your family. Mold spores could cause respiratory problems, particular for those who are prone to allergies or who have asthma.

If you know you have mold growing underneath your tiled floor I would first remove the old tile, perform a little mold abatement, permanently eliminate the source of water/moisture in the basement, and then re-tile the basement floor.
