May in Northeast Arkansas means one thing: humidity is about to spike. If your crawl space doesn't have proper moisture control, you're setting yourself up for problems that'll cost thousands down the road.
Here's what happens without a vapor barrier: ground moisture rises through your concrete or dirt floor, meets cooler air, and condenses on everything. Joists, subfloors, ductwork โ all of it becomes a breeding ground for mold and rot. I've pulled soggy insulation out of crawl spaces that looked like swamps.
The IRC requires 6-mil polyethylene vapor barriers in crawl spaces (Section R408.2). But here's the thing โ just laying plastic isn't enough. Proper installation means sealing seams with tape, running the barrier 6 inches up foundation walls, and ensuring complete coverage.
Better yet? Consider encapsulation. We seal the entire crawl space โ walls, floor, rim joists โ creating a controlled environment. Add a small dehumidifier, and you've got a dry, healthy space year-round.
I've seen crawl spaces in Jonesboro go from 85% relative humidity to 45% after proper encapsulation. That's the difference between wood rot and a solid foundation for decades.
With summer humidity rolling in, now's the time to address crawl space moisture. Waiting until you smell mold or see sagging floors? That's expensive remediation territory.
