Memorial Day weekend marks the start of serious humidity season in Northeast Arkansas. If your crawl space doesn't have proper vapor barrier protection, you're about to find out why moisture control matters.
A 6-mil polyethylene vapor barrier costs around $0.15 per square foot but prevents thousands in structural damage. Without it, soil moisture rises through your crawl space, creating 60-80% relative humidity even when it's dry outside.
Here's what happens next: floor joists start sagging, insulation falls down in soggy clumps, and mold spreads faster than you can spell "remediation." We've pulled out 47 tons of wet fiberglass from local crawl spaces this spring alone.
The IRC code (R408.2) requires ground cover in crawl spaces, but many older homes in Jonesboro and Trumann never got proper installation. The barrier should overlap seams by 6 inches, extend up foundation walls, and seal around piers with acoustic sealant or tape.
Proper crawl space encapsulation runs $3-7 per square foot depending on your foundation height and access. Compare that to $15,000+ for structural repairs after moisture damage sets in.
Summer's humidity train is leaving the station. Get your crawl space buttoned up now before the real heat arrives in July.
