Crawlspace

How humidity affects your crawl space

This diagram of the stack effect shows how cool air is pulled in through the lower levels of your home 

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 The Foundation Guys, 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.

SaniDry™ Sedona Dehumidifier

The SaniDry Sedona offers giant performance in a small package. It's the world's most efficient, high-performance dehumidifier, without a bulky heat exchange core. The Sedona easily fits in small crawl spaces, yet has a powerful blower to effectively dry large crawl spaces. Mold and mildew are common in crawl spaces, but the Sedona keeps the relative humidity below 55%, so mold won't stand a chance. As a high-efficiency ENERGY STAR® certified dehumidifier, the Sedona removes more moisture (100 pints per day) for less electricity cost than conventional models.

The SaniDry Sedona dehumidifier drains automatically and has a humidity sensor that monitors the air, so once it's installed, there's nothing else to do. Your crawl space will be drier and healthier - and so will the rest of your home too!
