How to level a pier and beam house

I forgot to mention in this video that winter is the best time of year to get under the house. Summer is as hot as hell!!! The amateurs who came before me did that with the beams, not me. The beams should be lapped.... I replaced the cinder blocks with solid cinder blocks. I like a firm platform for the beams to rest on. But, turning them on the sides does weaken them.
