Crawl Space Problem Signs in Columbia

If you own a home with a crawl space, there are several problem signs that you should be aware of when it comes to your crawl space’s health. A crawl space that has not been encapsulated will likely experience a buildup of humidity that can quickly spread to the rest of your home. Due to the humid climate of Columbia, this buildup can happen quickly. Another sign that your crawl space is succumbing to the elements is an increase in energy costs, as more effort is needed to keep your house at comfortable levels.

Causes of Crawl Space Damage in Columbia

There is a plethora of causes of crawl space damage. One cause of water damage in your crawl space has to do with the sand and clay soils of the area. The sandy soils allow water to easily drain through, while the clay soils will hold onto the water. Open crawl space vents may seem like a good idea; however, they actually let in water, unconditioned air, pests, and debris, causing more damage to your crawl space. The high humidity of the area also contributes to humidity inside your crawl space.
