First make sure you have stopped the water source that is creating your problem in the crawl. Moisture from the crawl can cause mold issues if not handled properly. It is very important to eliminate any and all standing water. Once standing water is removed a vapor barrier should be installed over 95% of the ground. At this point drying can take place. Depending on the source of the water drying may or may not be necessary. H2O Drying Solutions can take readings in your crawl to determine humidity and moisture content of the wood below your home or business.
