May in Jonesboro means 70-85% humidity, and your crawl space is absorbing every bit of it. That damp air isn't just sitting there—it's actively damaging your home from the ground up.
Unconditioned crawl spaces pull in outside air through vents and gaps. When humid air hits cool surfaces like rim joists and ductwork, it condenses. That's how you get standing water, mold growth, and rotting floor joists by July.
The numbers tell the story: Open crawl spaces can hit 90%+ relative humidity in Arkansas summers. Anything above 60% RH creates perfect conditions for mold and wood decay. Your HVAC ducts down there? They're working 30-40% harder when surrounded by swamp-like conditions.
Encapsulation with 6-mil poly sheeting and closed-cell spray foam changes everything. We seal the crawl space from outside air, control humidity with proper vapor barriers, and insulate the walls instead of the floor. Result: 40-50% humidity year-round and lower energy bills.
Real job from last week: 1,400 SF home in Trumann. Before encapsulation, crawl space hit 92% humidity. After our R-13 closed-cell wall treatment and vapor barrier, it stays at 45% RH even on 90-degree days.
Don't wait until you smell mold or feel bouncy floors. May is perfect timing to encapsulate before peak summer humidity arrives.
