rotted crawl space

Moisture damage. A crawl space that doesn’t have proper air flow will have problems with moisture, mold, and wood rot.

How humidity affects your crawl space

Homes have never been completely airtight structures, and over the years outside air is given more and more access through both the changes you’ve decided to make to it and the natural decay of building products. This allows humid air to get into your crawl space, where it inevitably condenses and begins to cause problems.

Warm air rises and exits through upper windows and the roof, creating a vacuum in your home. In below grade spaces, this void is filled with humid air drawn from the outside. Once in your crawl space, this air condenses and leaves standing water before it works its way up and out of the home. Known as the stack effect, this process will worsen over time and create mold and wood rot while hurting your energy efficiency.

At AFS Foundation & Waterproofing Specialists, we solve these problems with our crawl space encapsulation system and crawl space dehumidifiers. By sealing your crawl space off from the outside, we can create an environment that remains dry, clean, and healthy, as well as far more energy efficient.
