Do you have a crawl space? If so, you probably have noticed a few issues: moisture, ventilation, air quality, etc. These issues, if not dealt with, can lead to more serious problems, like poor indoor air quality, decreased energy efficiency, or mold. As they say, a stitch in time saves nine.


You have several options, including:

  1. Venting the crawl space to the outdoors,
  2. Venting some supply air from the HVAC system into the crawl space,
  3. Using an exhaust fan to move air from the crawl space to the outdoors, and
  4. Installing a dehumidifier (encapsulation).

Traditionally, most crawl spaces are vented to the outdoors. However, vented crawl spaces have a number of problems that seriously degrade a home’s performance. This is why, over the past decade or so, encapsulating crawl spaces has quickly increased in popularity. In fact, Energy Vanguard blogger Allison Bailes says “The best way to deal with the air in a crawl space is to encapsulate it and install a dehumidifier.” This will help eliminate the moisture problems that often result from vented crawl spaces.


Although more expensive than traditional methods for dealing with crawl space moisture, installing a dehumidifier is the best method for treating the air in a crawl space. Benefits include:

  1. Encapsulation helps improve indoor air quality, allowing you to breathe easier.
  2. Encapsulation helps control humidity, keeping the relative humidity below 60%.
  3. Encapsulation helps reduce moisture, which can lead to wood rot and costly home repairs.
  4. Encapsulation helps improve comfort.
  5. Encapsulation helps lower energy bills by as much as 20%.
  6. Encapsulation helps prolong HVAC life. Equipment and ductwork simply lasts longer in a conditioned space.
  7. Encapsulation helps you sell a home. An encapsulated crawl space is a great selling point.
