What Causes Crawl Space Moisture?

Building homes with open crawl space vents has been a longtime building practice, with the intent of drying the air under the house. But it has been found that this does more harm than good. Warm, moisture-filled air from the outside enters through open vents and mixes with the cooler air in the crawl space. As that air is heated it increases the relative humidity level. Molds and wood-rotting fungus thrive in 50% +RH (relative humidity). The nasty, heated air rises through your house and ends up being part of what your family breathes in the living area! 

Why Do I Need A Crawl Space Dehumidifier? 

You and your family could be inhaling a variety of unpleasant, harmful toxins in your home. Mold, dust mites, rodent waste and decay, and radon gas are all things that could be in your home and making you sick. 

More than 50% of the air you breathe indoors comes from the crawl space underneath the house. Because of the stack effect – air being drawn upwards through your home from bottom to top – whatever is in your crawl space also is in the air circulating throughout the rest of your home. If you have a vented dirt crawl space with any kind of water, moisture, and humidity, you also have the perfect conditions for mold and wood-rotting fungus growth, insect and rodent infestation, and damaged structural supports. 

The presence of mold can contribute to problems with asthma and allergies, as well as attract bugs that feast on the mold growth and destroy wooden supports. These rotting wood beams and floor joists threaten the stability of your home. Any wet, moldy, insect-ridden insulation is not effective, and this lack of proper insulation can raise heating and cooling costs. 

You don’t have to live with these conditions. JES has the right solutions you need to improve the health, stability, and function of your home’s crawl space. Combined with our other crawl space repair and encapsulation solutions, our crawl space dehumidifier is an innovative system that eliminates moisture in your crawl space.

Why Choose a JES Crawl Space Dehumidifier?

  • ENHANCED PROTECTION

The JES Crawl Space Dehumidifier works to clean and filter the air, control moisture and humidity, remove odors, and prevent mold and mildew growth. The overall air quality throughout the rest of your home also will be improved. 

  • LONG-LASTING DURABILITY

This dehumidification unit is designed for long-life operation in damp crawl space or basement conditions. Like all the solutions we install, the unit comes complete with a warranty and its operation and maintenance can be ensured by regular check-ups from our service technicians.

  • BETTER ENERGY EFFICIENCY AND SAVINGS

Our dehumidifier may be powerful, but it is an energy-efficient model that meets and exceeds ENERGY STAR® efficiency requirements. It can remove approximately 100 pints of water per day, as well as help you lower your energy and electric bills.  

  • CONVENIENT AND QUIET OPERATION

The JES dehumidifier is self-draining and can be directed to drain into the crawl space waterproofing or sump pump system, or a condensate pump can be installed. That means there are no buckets or reservoirs of water that you need to empty. The unit also has an internal fan that is insulated to significantly reduce operational noise.

How Does a Dehumidifier Factor into Crawl Space Encapsulation? 

Once the crawl space has been sealed, it’s important to condition the air. Dubbed the “the cherry on top” by industry professionals, a crawl space dehumidifier completes your crawl space encapsulation needs. With all things considered, dehumidifying your crawl space is the fourth and final step to crawl space encapsulation. 

Used in conjunction with the JES CrawlSeal™ Encapsulation System, the JES Dehumidifier works by removing and eliminating air moisture in your crawl space, draining the excess water to your sump pump system or outside. This discourages insects and rodents and makes your home a healthier place to live. Its other benefits include that it also protects the structural integrity of your home and can reduce energy costs from 15 – 25%! 

The truly unique aspect of a crawl space encapsulation dehumidifier is the fact that you never have to empty a bucket of water from your crawl space again. You don’t have to worry about controlling the water on your own because the dehumidifier releases the water through its own release mechanisms, whether it’s your sump pump or a condensate pump.

How Can I Keep My Home Dry and Healthy?

If you have been experiencing crawl space problem signs such as wet crawl space insulation or high indoor humidity, it’s important to properly address these issues with the right solutions. 

For excessive moisture and water, we waterproof the crawl space by placing the CrawlDrain™ perimeter drainage system in the crawl space floor to catch seeping water. This water is then directed to drain to a sump pump system, and it is then pumped out of the crawl space and away from your home’s foundation. 

It’s also important to seal the crawl space. Airtight vent covers are placed on the home’s exterior to conceal the vents, and then the crawl space is encapsulated. We use the JES CrawlSeal™ Encapsulation System. This durable 20-mil liner is placed on the crawl space walls and floor to completely isolate the area from the earth. CrawlSeal™ serves as a moisture and vapor barrier, and it helps insulate the crawl space. Rigid ExTremeBloc™ insulation panels also can be placed on the walls for the best protection. 

Frequently Asked Questions About Crawl Space Dehumidifiers

Crawl space dehumidification is an important part of a healthy crawl space. Could a crawl space dehumidifier be the answer to your worries?

Your first step when dealing with crawl space humidity should be to make sure you’ve encapsulated your crawl space with a durable vapor barrier, added a sump pump, waterproofed the space, and done anything else necessary to remove the source of humidity. However, if the humidity persists, a crawl space dehumidifier can be an amazing addition to your wet crawl space solutions.

Molds and wood-rotting fungi tend to thrive in humidity at or above 50%. That means you should ideally keep your crawl space humidity lower than 50% to avoid issues with mold and fungi. However, a crawl space expert can give you more information about your specific dehumidification needs.

When you choose a crawl space dehumidifier, it’s important to take into account the fact that a crawl space has different needs than the rest of your home. That’s why you can’t just purchase a dehumidifier that works for inside your home and put it in the crawl space. You need to choose a dehumidifier that a crawl space repair expert recommends.

Choosing the best dehumidifier for your crawl space can be a daunting task. Instead of trying to choose one on your own, you should talk to a JES crawl space repair expert. Schedule your inspection today to learn more about your personalized options to fix any crawl space moisture concerns.

Other Dehumidifier Considerations 

It’s important to realize all air dehumidifiers are NOT the same. Many homeowners think they can place a typical household dehumidifier in their crawl space and call it a day. However, there is one major reason why household dehumidifiers do not compare to crawl space encapsulation dehumidifiers…THEY ARE TOO SMALL! 

Due to the location of your crawl space and relative humidity, moisture accumulates at a much faster rate than the upper portions of your home. Meaning, household dehumidifiers are not equipped to handle such an intensive job. All the necessary components needed to make a dehumidifier effective i.e. the cold coil and fan, are not large enough to rid your crawl space of moisture. Plus, you’d have to constantly be in your crawl space to empty the reservoir of collected water or risk an overflow or flood. 

When it comes to a crawl space dehumidifier, there really is no comparison to the comprehensive benefits of the JES dehumidifier, especially when you look at all the benefits of crawl space encapsulation.
