Homeowner Charles L. called Crawl Space Solutions of Arkansas because his crawl space has moisture issues that are causing cupping in his hardwood floors in the living room.
Mold spores, the seeds of mold, are in the air everywhere. All they need to grow is organic material such as wood, the right temperature range, and moisture. Of these, the only one that can be controlled is moisture. Dirt crawl spaces have high humidity levels necessary for mold growth. Humidity levels from 50-90% are easily found in dirt crawl spaces that have never flooded. Mold can grow on dirt, insulation, framing, and even under your carpet on the first floor. Mold destroys organic materials as it feeds on them. Mold reproduces by producing millions of floating airborne spores, which some people are very sensitive to. Spores can be dormant for many years, waiting for the right conditions to grow. Some molds produce mycotoxin, such as the black mold Stachybotrys. Many articles have been written on the effects of mold and toxic mold.
Don't panic; there is a solution that will stop your crawl space from being a hospitable environment for mold. Mold will not grow when the humidity levels are reduced below 50%
