I am planning on hanging a pre hung exterior door that goes from the house into the garage. The pre hung door has the threshold attached to the door frame.
Tile was installed on top of a concrete floor with the tile butted up against the old threshold, but the new threshold that comes with the door is slightly wider.
So, the new threshold goes over the tile a little, leaving a 1/4 void underneath. The tile is approx. 1/4 inch high.
Should I install the pre hung door on the tile and fill the void underneath the new threshold with quick setting cement or should I cut away the tile a bit and have it butt up against the new threshold?
