I had a wall put up where a closet used to be and want to put in baseboard at the bottom. I have found that the floor is actually uneven and tapers at the end. So if I push the baseboard in for the green wall to make level, there's a gap towards the corner. It also looks higher than the baseboard on the white wall because the floor is lower for that baseboard.
I'm not sure what the best approach for this would be. I've thought about placing the baseboard where it is in the picture and scribing it, from where the gap is but I'm not sure if that would solve the varying height issue? I also thought of putting a corner block but I also don't think that would solve it. I'm very new to home reno stuff so any help would be much appreciated!
