Crawl Space Encapsulation in Dallas-Fort Worth TX

Crawl Space Encapsulation vs. Ventilation

Many homes in North Texas have crawl spaces, which are open areas between the house and the ground underneath. Crawl spaces also contain vents to enhance circulation and deter mold growth by allowing an exchange of air with the outside.

Unfortunately, vents don’t usually prevent mold and mildew growth in crawl spaces. In some cases, venting can make these problems worse. And when airborne contaminants like mold enter your home, they can cause significant allergy issues. That’s why our team at Align Foundation Repair offers an alternative approach to crawlspace maintenance called encapsulation.

What Is Crawl Space Encapsulation?

It entails the installation of a water vapor barrier, typically made of a rugged form of plastic called polyethylene. Encapsulating materials cover the entire crawl space, including the underlying ground and the walls. This material also blocks vents, which stops air exchange between the inside of the crawl space and the outside of the home.

How Does It Differ from Ventilation?

Building designers began adding vents to crawl spaces, hoping to reduce humidity and condensation in the closed-off area. They thought airflow throughout the space would help evaporate moisture, deter mold growth, and create an inhospitable environment for bacteria.

In reality, the differences in temperature inside and outside the home can actually increase condensation within this space. Humid exterior air flowing into crawl spaces will also accelerate the growth of mold and mildew while simultaneously creating a favorable condition for bacteria to thrive. And while closing crawl space vents can limit air exchange to some degree, it can’t rival the protection a durable water vapor barrier provides.

What Benefits Does Encapsulation Offer?

For most homeowners, encapsulation is a better option than ventilation in crawl spaces.

Encapsulation is associated with a variety of benefits, including:

  • Improved Air Quality – Encapsulating material keeps the air within the crawl space free of contaminants, creating a healthier environment.
  • Greater Energy Efficiency – When humidity is controlled in the crawl space, your home will no longer be plagued by it. That means your HVAC system can function more efficiently and keep home cooling costs affordable.
  • Decreased Moisture Damage – Increased crawl space humidity causes wood rot, which can negatively impact the stability of your home. In this case, encapsulation can protect you from expensive repairs caused by extended moisture exposure to wood and other components.
  • Enhanced Home Comfort – Better humidity control means a more comfortable home. You’ll enjoy a cool summer environment while reaping many other practical benefits.
