May in Northeast Arkansas means one thing: humidity is about to skyrocket. And if your crawl space doesn't have proper vapor barrier protection, you're setting yourself up for expensive problems.
Most Jonesboro-area homes sit on crawl spaces that turn into moisture magnets once our summer humidity kicks in. Without a proper 6-mil polyethylene vapor barrier sealed at the seams, that moisture migrates straight up through your floor joists and into your living space.
Here's what we see every June and July: crawl spaces hitting 80-90% relative humidity while homeowners wonder why their energy bills are through the roof. That moisture forces your HVAC system to work overtime removing humidity instead of just cooling air.
The IRC R402.2.10 requires vapor barriers in our climate zone, but many older homes never got them installed properly. We're talking about covering 100% of the ground surface with overlapped seams sealed with construction tape or mastic.
A properly installed vapor barrier typically runs $1.50-$2.50 per square foot depending on crawl space access and existing conditions. Compare that to the cost of replacing moisture-damaged floor joists or dealing with mold remediation later.
Best time to tackle this? Right now, before the real heat and humidity arrive. May weather makes crawl space work much more comfortable for our crews, and you'll start seeing energy savings immediately when summer hits.
