Crawl spaces are susceptible areas to mold growth due to the retention of water that exists in the soil, which can evaporate and create structural damage on your property, as well as create rotting damage on wooden joists and wood-based materials.
One of the most imperative installations that should exist in a crawl space is a vapor barrier. A vapor barrier is a thin sheathing of plastic, polyethylene that covers the ground in a crawl space. This ensures minimal water penetration into the ground, as well as water retention in the soils and reduces the ability of moisture evaporation in the area.
Another tip to reduce mold susceptibility in crawl space areas is to ensure there are no loose, organic materials in the area. Often, crawl spaces become neglected due to the subterranean nature of them; i.e. out of sight, out of mind. These areas are highly susceptible to water intrusions, especially during heavy water events-therefore, they should be maintained as such.
Loose materials can become damp and become ideal harboring grounds for mold. Always double-check crawl spaces areas after any type of maintenance workers have been in the area, since a lot of workers are inclined to leaving materials and tools behind.
