I had an undersized adjustable Lally column replaced. When the "contractor" installed the new one, he cranked it up too high and as a result, the beam is not level at all. This has caused a lot of my tiles on the first floor to crack, nail pops on the 2nd floor and Very creaky wood floors. I want to crank it down so that the beam is level, but can't get it to move. Any hints?
