Working on one right now but pier and beam so it's a pretty easy fix.

You can pour new temporary footings next to the existing ones in order to jack the beams up to where they need to be, then replace the existing posts with longer ones.

The blanket technique doesn't really work but if you use the vacant house list and absentee list and probate etc.. you can laser target your campaign. 

Sometimes you just can't get the beams and HVAC out of the way.

In addition, I only have a black/white laser printer so the blue and red lines would not show up.

If this is a pier and beam home I would consider installing a plastic liner in crawl space.

@Carson Sweezy I would say that you need to be laser focused on your "audience".

There's a ton to learn in this aspect though and you can't lose a lot of money quick if you're not careful but if you have your campaigns structured well, you can get in at a low overall monthly cost with laser like inbound filtering.Definitely worth the research.
