High Levels of Moisture in the Crawl Space Causes Big Problems in the Home

moldy floor joists in crawl space

An untreated crawl space can easily and regularly reach relative humidity levels of 60% or above, due to constant exposure to the moisture from the soil and humid outside air. This situation leads to the development of a variety of problems such as unpleasant odors, mold growth, dust mites and all sorts of critters that thrive in hot, humid environments.

While these problems are now well known and easy to address through encapsulation and proper drainage solutions, there is an additional factor that is often overlooked: condensation resulting from differences between temperatures inside the crawl space and outside. This is a common source of moisture issues that can significantly affect crawl spaces over time, even when they appear to be properly protected.

Dehumidification: The Definitive Solution for Crawl Space Mold Problems


The best solution against excessive moisture in your crawl space is a good, energy-efficient dehumidifier. These devices help keep the Relative Humidity at safe levels, preventing condensation and all the problems associated with high humidity.

As part of our Level 4 Healthy Crawl Space Certificate, Grate Products offer powerful specialty models designed specifically for optimal operation in crawl spaces, making them a far superior choice over standard hardware store models. In addition, as is the norm with our products and services, it is nationally backed by a Transferable Lifetime Warranty.
