And it is essential to opt for the best dehumidifier for crawl space to tackle the severe moisture problems.

Crawl spaces, as the name implies, are cramped places, with limited height so that they only allow a person to crawl in. The height ranges are mostly from 1 to 5 feet. They aren’t much different from the basements around the house, except for their limited headroom. They usually have a sandy or soil floor and are established in upper or lower story of the building.

These spaces have a number of advantages but sometimes the disadvantages weigh a lot more when it comes to the hostile environment of such spaces. Crawl spaces are the dampest and coldest part of the house because water can trap in there. The gravity causes the moisture from anywhere in the house to creep downwards, reaching the crawl spaces, hence, resulting in low levels of temperature and high level of moisture.

Reasons Behind High levels of Humidity in Crawl Spaces

There are certain major reasons that enhance the water content of the air in crawl spaces:

  • Water leakages either due to some plumbing or drainage problems ends up creating small ponds of water in the crawl spaces causing them to suffer from excessive moisture.
  • Sometimes on rainy days or in humid climates the outdoor air comes inside the vented crawl spaces and gets stuck. This air containing high levels of moisture can increase the humidity inside the crawl space. Such moisture can damage the wood, concrete and altogether the whole foundation of the house.
  • The water from around the house also creeps inside the walls, ceilings, and floors and reaches the crawl spaces making the air around them more humid.


If the crawl spaces, like basements, have bad ventilation, they face the problem of excessive moisture. If not dealt effectively and in time the moisture can penetrate the walls, roofs and floors and damage electrical installation and the structure of the house.


Proper ventilation is most of the times effective in solving the problem but when the situation gets out of hand, buying the best crawl space dehumidifier is necessary.
