We have painted wood doors on the second floor of our house. Several of them cracked within the panels, which the manufacturer suggested was very unusual, but blamed it on the fluctuations in humidity. I don't buy that since, once we had the doors delivered, our house was a good constant. I am wondering whether we should have them repaired or replaced. Additionally, some of the subs have accidentally damaged a few of them. Supposedly our painter can fix them, but I wonder how they will look brand new. Is this kind of damage common during a build? Should we demand they be replaced, withhold money and buy new ones ourselves, or let them fix them? The photos are of our upstairs doors' damage:
