Crawl Space Moisture

Crawl spaces are crucial areas of your home, providing access to important utilities and maintaining the structural integrity of your property. However, when moisture invades this space, it can lead to various problems, risking the health of your home and your family.  

Excess moisture encourages mold growth, attracts pests, causes wood rot, and raises energy bills as humidity transfers into your living space. The humidity can come from various sources. While crawl spaces are naturally damp, too much moisture causes significant damage.  

As homeowners ourselves, our team at Ohio Basement Authority understands how frustrating it can be to handle these issues. We specialize in identifying and resolving these common problems, ensuring your crawl space remains dry and functional. 

This page explores the causes and signs of crawl space moisture and how Ohio Basement Authority’s proprietary crawl space encapsulation solutions rid your home of them for good.

What Is Crawl Space Moisture? 

Moisture in the crawl space refers to any form of water present, whether from condensation, leaks, or high humidity levels.  

All crawl spaces retain some moisture due to their ground proximity. However, excess moisture causes problems. When the relative humidity in a crawl space surpasses approximately 55%, it becomes problematic. 

Elevated crawl space humidity results in many issues, including: 

Excessive moisture can permeate your living spaces, leading to an unhealthy indoor atmosphere and weakening your home’s structural foundation. In regions like Ohio and Northern Kentucky, where weather can be unpredictable, maintaining a dry crawl space becomes crucial for safeguarding your home. 

What Causes Crawl Space Moisture? 

There are several ways that moisture commonly gets into crawl spaces: 

  • Location: Crawl spaces are naturally prone to moisture due to their location beneath your home and exposed dirt floors. 
  • Weather: Ohio and Northern Kentucky are classified as having a humid continental climate. Our region’s varying weather conditions contribute to the challenge, with rain, snow, and humidity playing significant roles.  
  • Open Vents and Gaps: Open crawl space vents allow moisture to enter the crawl space from outdoors. Gaps around pipes and wires also permit humid air. 
  • Condensation: Warm, humid air from outside condenses on cooler crawl space surfaces. 
  • Leaking Water: Wall and vent leaks allow rain and groundwater to infiltrate the crawl space. 
  • Plumbing Leaks: Leaking pipes in the crawl space add extra water. 
  • High Groundwater: A high water table surrounds the crawl space with moisture. 
  • Surface Water: Poor drainage allows rain and surface water to pool around the foundation and seep in. 

Addressing these issues is imperative for the structural integrity of your home and the health and well-being of your family. 

Can You Fix Crawl Space Moisture? 

Yes, crawl space moisture can be solved. Addressing this issue is not just a suggestion; it is crucial for safety and structural integrity. 

Many homeowners believe they can install a store-bought dehumidifier in the crawl space and be done with it. However, we do not recommend DIY crawl space repairs, as they are temporary and potentially dangerous. 

Our experts at Ohio Basement Authority have effective techniques to tackle excess moisture at the source. We customize solutions based on our inspection of your crawl space, identifying the moisture’s entry point and the best ways to address it.
