We had closets built out by contractors, bifold doors on one and bypass on the other. They didn't finish the corners on the outside or inside of the closet with the corner beads. they are ridged and uneven. they’re claiming that it's because we wanted the closets trimmed. They insist that if corners will be trimmed they don't get finished neatly. sure, but I expected the inside trims finished and not trims. They are saying that trimmed closets means they're trimmed on the inside too. I've NEVER seen a closet trimmed on the inside, aside from a swing door walk in closet. Is this normal? This pic is from inside of the closet.
