Humidity is a measure of the amount of water in the air. When you hear the term "humidity" in the news, it refers to "relative humidity," a percentage of the maximum amount of water that the air can hold at the same temperature.

Because water particles in humid air retain heat, moist environments trap heat better than dryer ones. This gives the impression that the climate is warmer than if it were dry at the same temperature.

However, some humidity is beneficial. Dust and other particles disperse through the air and cause other problems if the environment is too dry. A little moisture is also helpful to your skin and respiratory system.

So, how humid should a sealed crawl space be? A reasonable range is 30 to 65 percent. Anything above 65 percent indicates a problem, and anything above 75 percent is cause for concern.


"I never spend any time in my crawl space," you may think. So why should I care if it's wet? " The short answer is that air from your crawlspace or basement can enter your living space via porous wood, flooring, and insulation. This is because air naturally flows to higher levels from the lowest point in your structure. This is known as the "stack effect," similar to smoke rising from a chimney.

This means that up to half of the air in your home came from your crawl space. There are three significant causes of crawl space humidity: 1. from the muddy ground 2. Because of the humid outside air and 3. Because of groundwater and flooding. Although the top layer of dirt in a crawl space may appear dry, moist dirt lies just beneath the surface. So it's a constant source of moisture that seeps into the air in your crawl space.

Most crawl spaces have ventilation, allowing air to flow freely in and out of the space. So, if the humidity outside is high, the air in your crawl space is likely to be as well. This can cause a slew of issues in your home.

In addition to the health and structural issues mentioned above, high humidity can also cause your air conditioning unit to work harder and increase your energy costs. Furthermore, excessive moisture can lead to the growth of mold and mildew, which can cause respiratory problems.

If you have a crawl space dehumidifier in place, it will automatically turn on and off to maintain the desired humidity level. This will help keep your home healthy and comfortable while saving you money on energy costs.


Carolina Crawlspace Pros offers a variety of crawl space dehumidifiers to choose from, including desiccant and refrigerant models.

- Desiccant crawl space dehumidifiers use a desiccant wheel to absorb moisture from the air. The wheel is then heated, which releases the moisture and dries the air.

- Refrigerant crawl space dehumidifiers use coils filled with refrigerant to cool the surrounding air. This causes the water vapor in the air to condense and be collected in a reservoir.

Both types of crawl space dehumidifiers have their benefits and drawbacks. Desiccant models are typically more energy-efficient, but they can take longer to dry the air. Refrigerant models are faster at drying the air, but they use more energy. Carolina Crawlspace Pros can help you choose the right crawl space dehumidifier for your home and needs.
