High-performance dehumidification & air filtration for your crawl space

rotted crawl space

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

Humidity and condensation in a crawl space is a recipe for disaster. Excess moisture leads to mold growth, wood rot, and foul odors, causing issues for your home's health, air quality, and value.

At Regional Foundation Solutions, we specialize in preventing these problems with our patented crawl space dehumidifier and ventilation fan. As part of our complete crawl space encapsulation system, these products will ensure that your home has clean, dry air and help protect your crawl space from mold and other damage.

If you've had issues with mold, wood rot, or other crawl space humidity problems, call us today at 1-855-225-2564 or contact us online to learn more about how we can help! We offer free estimates on all our work in Durham, Raleigh, Greenville and throughout the surrounding areas in North Carolina.

Why crawl space humidity begins

the stack effect

This diagram of the stack effect shows how cool air is pulled in through the lower levels of your home (click to enlarge)

Homes have never been completely airtight structures, from construction when contractors cut channels through walls and floors for pipes, wires, cables, and ducts, to years later when outside air was given more access through both the changes you've made and the natural decay of building products, humid air gets 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 Regional Foundation Solutions, 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.

How crawl space humidity affects the home

Crawl space humidity leads to all of the following problems in your home:

  • Rotting & Mold
  • Rusted, Corroded Metal
  • Odors & Allergens
  • Higher Utility Bills

As crawl space humidity increases, mold and rot begin to grow, damaging all the organic material in your crawl space, including wooden floorboards and structural support beams. Crawl space rot then causes sagging, uneven floors above, in some extreme cases, sections of the floor to cave in, and pest infiltration, like termites, carpenter ants, wood-eating beetles, and more who love rotting, moldy wood.

As mold and rot increase and animals begin to live (and die) in your crawl space, the odors and air will begin to rise into your home. Mold spores are a known allergen, and they can significantly affect anyone in the home who suffers from asthma or allergies.

During the hot summer months, crawl space humidity also increases your home's cooling bills. A large part of the job of an air conditioner is to dehumidify the air as it cools. Humid air is much more expensive to cool than dry air and, of course, that freezing cold winter air that enters through the crawl space vents isn't helping either.


Controlling crawl space humidity

Crawl space moisture control system includes:

  • Sealing crawl space vents
  • Installing a crawl space vapor barrier on walls & floors
  • Installing an energy-efficient crawl space dehumidifier

Warmth, moisture, and organic building materials are three components feeding mold to grow and thrive within the crawl space. Moisture is the easiest of these to regulate and with the moisture control system from Regional Foundation Solutions, not only will crawl space humidity be lowered, but it will also be sealed for added protection and storage space.

Our crawl space experts know exactly how to seal and control crawl space humidity quickly and efficiently, with a moisture control system that takes less than a day to install!

SaniDry™ Sedona Dehumidifier

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!
