Do You Really Need One?
Everybody knows that crawlspaces are extremely damp, even if they should not be. Moisture can lead to dangerous mold growth that will affect your health and it can damage the supporting structure as well. In most cases, even a well-insulated space can become a home for mold and mildew and that is a dangerous situation that should be solved immediately. The worst part is that chances are you will notice the moisture problem when it has already affected your house in a serious matter. That is why a dehumidifier is in demand for keeping moisture under control.
How We Tested
Evidently, the aspect of the greatest importance is the efficiency of the device when it comes to lowering humidity levels and normalizing them. To test all products and see just how well they perform from this point of view, we first tested humidity levels indoors with the help of a humidistat, and then let each device run for 2 hours. After the time passed, we tested humidity levels again to see what difference was made by the use of each dehumidifier, and compared results in order to rank the products according to their performance quality.
Even though it will mostly be out of your way, it is still important to check the noise output as it can become an issue at a given point. This is why we took it upon ourselves to test each product and see what is the noise level produced when it operates. We tested this parameter with the help of a decibel meter that was placed 1 foot away from the device, comparing the results to see what models are quieter when they run.
In order to figure out how big of a difference using these devices will make when the electric bills arrive, we tested each of them to see how much power they draw in order to remove 10 pints of moisture. This is the best way to determine energy efficiency, a factor of great importance to any customer as no one desires to end up with an energy draining device that is too expensive to run, especially those who deal with extreme dampness and need to rely on it constantly.
The crawlway can get pretty cold, so it is important for the dehumidifier you place in it to withstand the environmental conditions in order for it to function properly. At a steady 40 degrees Fahrenheit temperature, we checked each and every product to see if it operates just as well as it does in regular temperature environments, and we checked for frost to not build up inside either.
|Product||Humidity removal||Noise output||Energy efficiency||Low temperature operation|
|Overall score: 10/10|
|Overall score: 9/10|
|Overall score: 8.3/10|

Advantages of Crawlway Dehumidification
Given the narrow design, these spaces require a special type of dehumidifier that will fit and will be powerful enough to absorb all the air humidity. While basement or industrial models can be too big and bulky for the space available and the regular room units are not powerful enough, the crawlway moisture removal device is a perfect choice. Most moisture removal devices are compact, rugged and will be able to retain mold from affecting the walls of your home, thus, damaging its structure.
In addition, they will also protect your health. In fact, it is important to know that what is hidden in your crawlway will eventually end up in your home. We all know that our homes are filled with invisible mold spores that float through the air. You might think that it is a long way to your bedroom, but mold spores travel very fast and it won’t be long until they will reach your entire house. These tiny particles are the main cause of allergies and other health issues. However, in order to prevent these problems, it is recommended to install a quality moisture removal device in your encapsulated crawlspace. As mentioned before, by installing such a device, you can improve the air quality in your home. Plus, by controlling moisture you can reduce or prevents symptoms of allergies, such as eye irritation, headaches, and respiratory problems, as well.
Crawlway vs. Basement Dehumidification Devices
Once you start seeing mold signs in your house, you must take immediate action and invest in a dehumidifier that can deal with large areas like the crawlway. At a closer look at the market, you will notice that there are two types that are advertised to work in both basements and crawlways. These two types are very similar and you can count on each one of them, considering that they are very much alike.
They are pretty much the same size, being designed for large areas like cellars, garages, crawlspaces, and basements. Also, they have a high absorbing power that enables them to deal with excessive humidity cases.
In addition, you must make sure that the one you choose can operate in low temperatures so a defrost feature is mandatory. Also, take into account that you will hardly reach it to empty the tank so it is best to go with a model with a pump that evacuates the moisture on its own. The only noticeable difference between the two types is the shape, more exactly the horizontal position of the device. This one must be shorter in order to fit shorter areas but this is only required if your crawlway is very small in height. Otherwise, you can go with a basement unit without any worries.
Where Does the Moisture Come From?
There are quite a few factors which contribute to high humidity in the crawlway, and the bright side is that you can take proper measures to combat them if you know what to look for, thus fixing moisture levels to prevent the devastating consequences which will ultimately unfold if you are not careful.
- Outside air: Vents and openings are the sources through which outside air enters the crawlway, raising the relative humidity inside as condensation can form due to discrepancies in temperature. During spring and summer, it is all the more likely for outside air to be the main culprit as it is high in humidity, inevitably transporting the excess moisture inside.
- Standing water: Always check to see if there are puddles in the crawlway as their presence might indicate a more severe problem which needs rapid tending to. What you must do if this situation emerges is check for leaky plumbing or drainage problems around the house.
- Ground moisture: Evaporation is the culprit here, moisture in the ground being released into the air and ultimately raising humidity levels. You must check the foundation walls as well, as they can release moisture as well. If you suspect that the walls of the foundation are the problem, you should add a coat of waterproof paint. When it comes to the ground, you can cover it with plastic sheets to diminish the release of vapors into the air .
TIP: To obtain the best results, we recommend that, in addition to adding a moisture removing device to this area, that you install a vapor barrier as well. basically, you should seal it off from the outside so that the aid inside remains healthy, clean, and dry.

F.A.Q. If I already have mold in the crawlspace, how should I proceed with the installation of the dehumidifier?
In case mold has already made an appearance, you first have to remove it, and then install the dehumidifier. The role of this device is to maintain proper humidity levels by removing excess moisture, so it is intended for upkeep, not for the elimination of pre-existing mold.
Will the appliance prevent mold from being a reoccurring issue?
Yes, as aforementioned, the role of the moisture removing appliance is to prevent the apparition of mold by maintaining proper humidity levels. If you eliminate the pre-existing mold and install the dehumidification device, this issue will not reoccur ever again.
Is it important to look into the noise output of the moisture removing appliance?
Considering you most probably live in an adjacent room to the crawlspace, yes, it is important to look into the noise output of the device. If it is near rooms like your home office, bedroom, the nursery, or living room, you will be inevitably bothered by the noise output of the appliance. For the moisture removing device to not present a nuisance, we recommend you go for a model which produces less than 60 dB when it runs.
How much moisture should the appliance remove per day?
The question to this answer strictly depends on your specific needs. There is no way to say that a certain capacity dehumidifier is more appropriate for you without checking how severe your humidity problems are first. However, if we were to give you a piece of advice, we would recommend you go for one that is capable of removing at least 50 pints of moisture per day as it is indicated to go for bigger rather than smaller from this point of view.
Finding a dehumidification device is not necessarily the easiest thing to do as the market for these products is filled with many “duds”. To make sure that you won’t end up spending your cash on a dehumidifier that won’t actually deliver the performance it promises, we recommend you check the comparison table at the beginning of our article once again and make a pick from the ones we put at your disposal as these products are all tested and guaranteed to work great.
Let us review some of them once again. The Thermastor Santa Fe Compact 2 ranks first as it can handle reducing air moisture in spaces of up to 1600 square feet. Furthermore, it can work even when the environment is extremely cold, and it comes with an integrated pump which makes operating it a lot more convenient as the moisture is automatically drained. If our first pick is a bit too spicy for your budget, however, we recommend you opt for the Fral FDK54 as it not only comes at a cheap price, but it provides a generous performance in terms of moisture removal, eliminating up to 10 gallons of excess humidity from the air per day.
