This page will guide you through the causes and issues related to crawl space humidity and how professional help provides a permanent fix. 

What Is Crawl Space Humidity? 

Crawl space humidity refers to the excessive moisture present in the crawl space area of your home, located between the ground and the first floor. This zone is prone to moisture due to its proximity to the soil. Humidity levels exceeding 60% can cause various issues, such as: 

These problems can affect the structural soundness of your home and pose serious health risks to its inhabitants. It’s essential to keep crawl space humidity under control to prevent these issues and maintain a healthy living environment. 

What Causes Crawl Space Humidity? 

Several factors contribute to high humidity levels in crawl spaces: 

  • Moist Soil: The bare earth floors typical in crawl spaces absorb water and release moisture into the air, acting like a natural humidifier. 
  • Open Vents: Florida’s humid air can enter through open vents and then condense on cooler surfaces. This is a major cause of high humidity in many homes across our state. 
  • Inadequate Insulation: Crawl spaces are often cooler than the rest of the house, causing condensation. Poor insulation and waterproofing can permit moisture ingress, creating an ideal environment for mold and wood rot. 
  • Faulty or Missing Vapor Barrier: A missing or damaged vapor barrier allows outdoor moisture to permeate the crawl space. 
  • Ineffective Drainage: Internal leaks in your crawl space can lead to standing water, adding more moisture to the air as the water evaporates. 

Addressing these issues promptly and effectively is vital for maintaining the structural integrity of your home and the health of its occupants. 

Can You Fix Crawl Space Humidity? 

Yes, it’s possible to resolve crawl space humidity, but it requires a comprehensive and lasting approach. While DIY methods might provide temporary relief, they are not long-term solutions.  

Standard dehumidifiers, for example, are inadequate at controlling the air in large crawl spaces. Additionally, many dehumidifiers have to be emptied by hand, making it inconvenient (and potentially unsafe) to crawl below your home just to empty the water.
