The twisted beams are common and normally do not cause any problems. The leveling of the upper floor may be caused from the screw jacks not being let down if there are any.

It depends on how wide the gap is. If it is 3/4” or greater you should use Perma Chink. If it is smaller use Energy Seal. Call Dave at Timeless Wood Care Products at 800-564-2987 for help and the correct material.
