Memorial Day weekend in Northeast Arkansas means one thing: summer humidity is about to hit hard. If your crawl space doesn't have proper vapor barrier protection, you're setting yourself up for problems.
Here's what happens without a vapor barrier: ground moisture rises through your concrete slab or dirt floor, meets cool air from your AC ducts, and creates the perfect breeding ground for mold and rot. Arkansas clay soil holds moisture like a sponge, especially after our spring rains.
A 6-mil polyethylene vapor barrier costs around $0.50 per square foot installed, but saves you thousands in structural damage and energy waste. We're seeing 15-20% higher cooling bills in homes with unprotected crawl spaces because that humidity makes your AC work overtime.
The key details: overlap seams by 6 inches, seal with tape, and run the barrier 6 inches up foundation walls. For extra protection, we recommend encapsulation with closed-cell spray foam on rim joists — adds R-6 insulation while blocking air infiltration completely.
Best time to install? Right now, before July temperatures hit the 90s and make crawl space work miserable. Plus, you'll feel the energy savings immediately when summer cooling season starts.
