I am in the process of my first ever DIY carpet installation, in a room that has bi-fold doors for the closet. During tear-out of the previous carpet, I wasn't observant enough to notice if the floor underneath the lower hinge brackets had carpet underlay installed, or not. While installing my new carpet underlay, I did add in some small pieces there... but now I'm worried that if I proceed this way, that once I have the carpet down over that pad, the lower hinge brackets won't line up with the original screw holes in the door jamb. (As it stands right now, if I test-fit the hinge brackets directly over the padding, I must press down on them a little to get the original holes to line up. But, my new pad is thicker than the previous one.)
Do the areas pictured usually have small wedges of carpet underlay pad placed in them, like I've done in the picture below?
