Should you Install a Dehumidifier in your Crawlspace?

Everybody knows that crawlspaces are extremely damp, even if they shouldn’t 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 crawlspace 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’s why a dehumidifier for crawlspace is in demand for keeping moisture under control.

The Advantages of Using One

Given the narrow design, crawlspaces require a special type of dehumidifier that will fit and will be powerful enough to absorb all the air humidity. While basement or industrial dehumidifiers can be too big and bulky for the space available and the regular room units are not powerful enough, the crawlspace dehumidifier is a perfect choice. Most units 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’s important to know that what is hidden in your crawlspace will eventually end up in your homes. We all know that our homes are filled with invisible mold spores that float through the air. You might think that it’s a long way from the crawlspace 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’s recommended to install a quality dehumidifier 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.

Crawlspace vs. Basement Dehumidifier

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 crawlspace. At a closer look at the market, you will notice that there are two types that are advertised to work in both basements and crawlspace. 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’s 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 crawlspace dehumidifier. This one must be shorter in order to fit shorter areas but this is only required if your crawlspace is very small in height. Otherwise, you can go with a basement unit without any worries.

    I want to install the dehumidifier in the basement, but there’s where I have set up my home office. Can you recommend a model that is quiet enough to not bother me while I’m working?

    Is the Dri-Eaz F413 Revolution really up for the job in 7,000 sq.ft. spaces? I have a very large crawlspace of around 6,500 sq.ft. and I wouldn’t want to have to purchase two smaller range units.

      Rest assured as this product can handle that room size and above. It’s highly powerful and able to absorb a great amount of moisture from the air. It has been tested in rooms measuring 7,000 sq. ft. and it was up for the job.
