Mold is a serious health concern and many of the homes in the Poseville area suffer from it. Mold occurs when the indoor humidity levels are high, the area is warm, and there is organic material for the mold to feed on. This set of criteria describes crawlspaces perfectly. From the dirt floor to the wooden sub-floor joists, there is a great deal of organic material for mold to feed on. Here, you can see the mold and fungus growing along the wooden joists in this crawlspace. The whitish blobs are actually spider sacks (the closer white mark in the upper left) and fungal growth (present on second joist from the front). In the second picture, you can see the first joist has received a mold treatment and scrub down to remove the fungus. For contrast, you can still see the Mold-X treatment on the bottom of the joist, which will be scrubbed next. Mold removal isn't going to fix this crawlspace because the underlying humidity issues are still present. After the mold has been removed, the entire crawlspace will be encapsulated with CleanSpace, the most technologically advanced vapor barrier on the market. It's going to reduce water intrusion and allow the crawlspace to be "conditioned space" when a dehumidifier called a SaniDry is installed.
