Aluminum Door Threshold on Concrete Slab
Installing a steel door with an aluminum threshold onto a flat/level concrete pad for a garage entrance. Some installers like to “glue” down the threshold onto the floor but if it needs to be replaced/moved later on, it makes for a PIA to remove.
Since the door unit is a pre-hung door and the threshold is already attached to the door framing. Can’t the door frame just be screwed to the rough opening wood and the threshold installed “dry”?
