Crawl Space Dehumidifier – Does Your Home Need One?

Posted on July 30, 2022

Crawl Space Dehumidifiers

Crawl space moisture can be a problem for homeowners who live in damp, humid climates. Depending on the extent of moisture, your home may become permanently damaged. Foundation repairs can reach the ten-thousand-dollar price range. Foundation repair wisdom says to prevent the damage with encapsulation. What happens when you cannot currently afford encapsulation? How do you counter the effects of crawl space moisture?

People research crawl space dehumidifiers online all the time to save money. Crawl space dehumidifiers work to maintain a dry space, but assuming it is usable in every situation would be an oversight. Is a crawl space dehumidifier right for your home? Read our take on this quick fix for wet crawl spaces. 

What is a Crawl Space Dehumidifier?

A crawl space dehumidifier removes moisture from the air by using evaporation and condensation to absorb water vapor into the machine. The water droplets in the air enter the dehumidifier, it removes them sending fresh, dry air back out. Depending on the type of moisture problem, you can determine whether or not a dehumidifier is right for you. 

Is a Crawl Space Dehumidifier Right for your Home? 

Not every situation calls for a crawl space dehumidifier. Some moisture problems require more intervention. Indoor areas do not need a crawl space dehumidifier unless you have some minor flooding and need to clear the air. Garages, sheds, and basements can all possibly benefit from a crawl space dehumidifier. Here are some situations where one will work. 

    • When your crawl space has a humidity of above 60 percent, use a humidity meter or hygrometer to measure the air. 
    • Condensation on windows indicates a humid environment. 
    • Encapsulated and non-encapsulated areas benefit from them.

When A Dehumidifier Is Not Enough

Crawl spaces may need more than a dehumidifier to stay dry. In some instances, you will need encapsulation to prevent radon, rot, and mold spores from accumulating in it. Here are a few ways to help you know they are not enough.

    • The humidity does not lower or lowers very little on the hygrometer.
    • The crawl space constantly needs a dehumidifier to maintain the ideal humidity range. 
    • When your home has flooded, you need a pump to remove excess water before using a dehumidifier. 
    • If you have excessive radon or mold spores, you may need to have that specifically attended to. 
    • When your home has wood rot or erosion, this indicates foundation damage. Contact your local foundation specialist.
    • Constant flooding means you may need French drains or sump pumps. 

Constantly humid crawl spaces need encapsulation. It seals the moisture out of your crawl space. Contact Atlantic Foundation for more information on encapsulation or installing a moisture barrier, or for any of your foundation needs.
