Tilt-a-hallway
It doesn't take an expert to see the obvious slanting of this hallway. It does however take an expert to fix it. Do you want your house to look like a carnival ride? Didn't think so.

Smart Jack #1
A series of Smart Jacks were installed under the hallway along the main load beams. By re-supporting the load beams and, in fact, raising them back up to level, we have halted any further sagging of the floors or worsening dry wall cracks.
Smart Jack #2
Here is the second of a seven Smart Jack system along the main load beam. Notice the screw-like characteristics. These units are adjustable to increase or decrease the amount of upward force they exert.
