I run into that a lot, too. Customer had some big outfit built or remodel a home. Then they found problems with the workmanship but are so mad at the builder that they do not want to call them. So I get to fix it.
Sometimes I wonder why I do not get away with mistakes if I make any. I always get to fix them myself( at no charge of course). Better do it right the first time around the next time.

Brett,

call the framer and for back up have another framer or engineer on side, also.
