High Crawl Space Humidity

Crawl space humidity is a common concern in many households, leading to a range of issues from structural damage to health risks. Managing humidity levels is key to maintaining a healthy and safe living environment in your home. 

With our extensive experience and expertise, AFS assists homeowners in the Southeast United States in effectively dealing with crawl space humidity. Our skilled team performs detailed inspections to pinpoint humidity sources and offers customized crawl space encapsulation to resolve these issues efficiently. 

This page will walk you through understanding the causes and problems associated with crawl space humidity and how professional help can permanently solve them. 

What Is Crawl Space Humidity? 

Crawl space humidity is the excessive moisture found in the crawl space of your home, situated between the ground and the first floor. This area is susceptible to dampness due to its close contact with the earth. Humidity levels over 60% can lead to various problems, including: 

These issues can compromise your home’s structural integrity and pose significant health risks to residents. It’s vital to maintain appropriate humidity levels in the crawl space to avoid these problems and ensure a healthy living space. 

What Causes Crawl Space Humidity? 

Multiple factors contribute to high humidity in crawl spaces: 

  • Moist Ground: The bare dirt floors (common in a crawl space) collect water and emit moisture into the air, functioning like a natural humidifier. 
  • Open Vents: Humid air from outside enters through open vents and condenses on cooler surfaces. The climate in the Southeast, with its hot summers and cool winters, can worsen these issues as the external air mixes with the cooler crawl space air, leading to condensation. 
  • Inadequate Climate Control: Crawl spaces are typically cooler than the rest of the house, leading to condensation. Insufficient insulation and waterproofing can allow moisture to enter and stay in the crawl space, creating a perfect environment for mold and wood rot. 
  • Absent or Damaged Vapor Barrier: Without a proper vapor barrier, outdoor moisture will slowly seep into the crawl space. 
  • Poor Drainage: If an internal leak happens in your crawl space, the standing water will put additional moisture to the air. 

Prompt and effective resolution of these issues is crucial for maintaining your home’s structural integrity and the health of its occupants. 

Can You Fix Crawl Space Humidity? 

Yes, resolving crawl space humidity is achievable, but it requires a comprehensive strategy for lasting results. 

DIY solutions might offer temporary relief, but they are not sustainable long-term solutions. Standard dehumidifiers, for instance, are insufficient for large crawl spaces and high humidity levels. 

Moreover, entering your crawl space without proper safety equipment is not recommended due to potential hazards.

Tackling Crawl Space Humidity with AFS

  • Safeguard Structural Integrity: Moisture leads to wood deterioration, affecting floors and beams. Promptly managing humidity in your crawl space with AFS helps prevent wood decay, floor sagging, and other structural problems. 
  • Protect Health: High humidity levels, above 60%, foster mold growth, which can harm wood structures and cause health issues. Keeping your crawl space dry with AFS solutions helps prevent mold growth, ensuring the well-being of your loved ones.
