Crawl Space Encapsulation - Covered up the exposed areas.

We then protective-wrapped the crawl space piers with 12-mil thick "pinkie" rolls, and installed a heavy-duty tear-resistant 20-mil CleanSpace vinyl liner. We also installed durable plastic Everlast vent door covers over the crawl space access. These doors completely seal the crawl space openings, but are still easy to open with a few twist knobs.
