As you said he should have built up under the bullnose to get the joint between the floor boards and the edge of the bullnose at the same height. Are the ends of the floor boards that abut the bullnose in a straight line? What is the height difference the surface of the bullnose and the floor boards? Which got installed first the floor boards or the bullnose?
I'm not sure which was installed first. Which way SHOULD they have gone?
The ends of the floorboards are mostly straight, but they're certainly not flush. I feel like that part is OK, albeit not stellar. Here's a pic I took earlier.
I guess I keep looking at it, thinking to myself "it looks like *I* did it, not like a wood flooring expert did them." I hired it out so that it wouldn't look that way!
The installer is going to pull up the bullnose and try again. Hope it comes out better next time!
