        "text": "No, you should never install new tile directly over an existing subfloor without checking its structural condition and installing a proper underlayment. Laying tile directly on standard plywood or OSB subfloors leads to cracked tiles and crumbling grout lines because wood expands and contracts with moisture. Proper installation requires a clean, level surface covered with a cement backer board or an uncoupling waterproof membrane. If our crew finds rot, moisture damage, or deflection around the toilet flange during tear-out, those structural repairs must happen before any thin-set mortar is applied.",

        "description": "No. Tile requires a rigid, stable underlayment like cement board or an uncoupling membrane over the subfloor to prevent seasonal movement from cracking the tile and grout."
