Conditioned vent system in a crawl space

In our experience, there are occasions where a vapor barrier (crawl space encapsulation) isn’t sufficient on its own in combating moist air that develops in crawl spaces. At Foundation Medix, we can condition your crawl space alongside a vapor barrier so that you have that added peace of mind.

Why Is Crawl Space Encapsulation Not Enough?

There are conditions in which the crawl space vents that were up to code years ago hurt rather than helped in keeping a crawl space dry. Recent studies suggest that venting your crawl space year-round is no longer beneficial for homes in certain geographical areas that experience more wet weather. In fact, it can have a negative effect on crawl space humidity levels and your home’s energy efficiency. Neglecting a crawl space that has humidity issues will only lead to mold growth and wood rot, which in turn invites wood-boring insects. Then, not only will you have to worry about humidity, but damage to your underlying structure as well.

Why Do So Many Homes Have Vent Systems?

Newly constructed homes are often built with the option of vented or unvented crawl spaces. However, homeowners with existing vented crawl spaces are often advised to close off those vents. Think of it along the lines of leaving a window open year-round, exposing you to heat in the summer and cold in the winter. Leaving these vents open allows for cold floors in the winter and hot living spaces in the summer. It is important to work with a reputable foundation repair expert such as Foundation Medix. We keep up to date on local codes and will determine the best possible option for your home.

Understanding The Conditioned Crawl Space Process

A conditioned crawl space, as the name implies, requires that the temperature within the crawl space be maintained just like the other rooms of your home. Existing crawl space vents are often blocked off with styrofoam blocks. The actual product used will be determined by the type of vents that exist.

We can condition the crawl space air by connecting a vent from your HVAC system to the crawl space. This way, fresh air will constantly be entering your crawl space, creating healthy airflow. If your home’s ductwork is located in the crawl space, a tap can easily be made in the existing duct. Other methods are used if your home’s ductwork isn’t located in the crawl space.

It may also be necessary to use a dehumidifier as part of the conditioned crawl space process to remove any existing humid air.
