It's a little late to ask, since they are here installing the floor now, but
there is a question on which way the floor should be laid in relation to the
floor joist. The joist run perpendicular on the new addition to those in
the old area, and we'd really like to keep the floor running the same
direction throughout. the new area is a family room that opens off the new
kitchen that is in the old area. There really isn't a good place to
'transition' from one direction to the other.

The installers say it isn't an issue, just run it all the one way (which is
perpendicular to the new joist). The general contractor says we should
transition. I've opted for the flooring guy's opinion, and the builder has
pretty much given in, but says if there are problems it will be the flooring
guys responsibility to fix it.

Should I sleep well tonight with the floor looking the way I would like it
to look, or should I toss and turn knowing I'll have flooring problems down
the road?

It sounds like you're saying the new flooring is perpendicular to the
new joists and the old is parallel? I'm surprised the contractor
wouldn't be pleased if that is the case as that is the normal. Whether
I'd be concerned at all depends on what the underlayment is and what the
flooring actually is--I'm assuming you're talking strip wood but don't
say whether it's one of the prefinished products or traditional.
