Back when i was a termite twchnician for cooks, i put alot of moisture barriers in and i inspected a few encapsulated crawlspaces. Suckers are nice hands down better than a traditional MB..but wayyyy more expensive. I heard of alabama fondation doin one about 4500sq ft an i think it was like 6 or 7 thousand dollars. Vs. A $300 MB. They nice tho its like a swimming pool liner under your house. So clean you can bout eat offem tho.
