Crawl Space Humidity

Crawl space humidity is a prevalent issue in many homes, leading to many problems ranging from structural damage to health concerns. 

Controlling humidity levels improves the condition of your crawl space and creates a safer and healthier living environment for you and your family. 

Ohio Basement Authority, with 15 years of experience and expertise, helps homeowners in Central and Southern Ohio tackle this challenge head-on. Our dedicated team conducts comprehensive inspections to identify the source of humidity and provides tailored crawl space encapsulation solutions to address them effectively. 

This page guides you through the causes and problems of crawl space humidity, and how to solve them permanently with professional assistance. 

What Is Crawl Space Humidity? 

Crawl space humidity refers to the excess moisture present in the crawl space area of your home. This space, located between the ground and the first floor, is prone to becoming damp due to its proximity to the soil.  

Levels above 60% relative humidity can cause problems, including: 

These problems not only affect the structural integrity of your home but can also pose serious health risks to its inhabitants. It is crucial to maintain optimal humidity levels in the crawl space to prevent these issues and ensure a healthy living environment. 

What Causes Crawl Space Humidity? 

Several factors cause elevated humidity in crawl spaces: 

The humid air entering through open vents also significantly raises humidity levels.  

  • Water Intrusion: Leaking pipes, groundwater, rain/snowmelt seeping through walls and floors add moisture to the air. 
  • Damp Soil: The exposed dirt floor releases moisture into the air, acting like an evaporative humidifier. 
  • Unsealed Vents: Outdoor humid air enters the open vents and condenses on cool surfaces. Ohio’s climate, characterized by hot summers and cold winters, can exacerbate these issues as the external air interacts with the cool crawl space, leading to condensation.  
  • Lack of Climate Control: Crawl spaces are colder than inside, causing condensation. Poor insulation and inadequate waterproofing can allow moisture to penetrate and remain in the crawl space, creating an ideal environment for mold growth and wood rot. 
  • Missing Vapor Barrier: Allows moisture from the earth to evaporate into the crawl space. 
  • Lack of Drainage: Standing water creates pools that add moisture to the air. 

Addressing these issues promptly and effectively is essential to maintaining the structural integrity of your home and the health of its inhabitants. 

Can You Fix Crawl Space Humidity? 

Yes, crawl space humidity is a solvable issue. However, it requires a comprehensive approach to ensure long-lasting results. 

Trying DIY fixes may provide temporary relief, but they won’t work long-term. For example, dehumidifiers are helpful, but conventional models are no match for vast crawl spaces and excessive humidity levels. 

Additionally, we do not recommend venturing into your crawl space, as it can be a delicate and dangerous area without the proper protective equipment. 

Ohio Basement Authority provides comprehensive, custom-designed crawl space encapsulation systems to permanently solve humidity and moisture problems. Our solutions control moisture at the source, ensuring a dry and healthy living environment.

Why Address Crawl Space Humidity Now 

It’s crucial to address high humidity in your crawl space as soon as possible. Here’s why: 

  • Prevent Structural Damage: Dampness causes wood to decay, compromising floors, beams, and stability. Addressing humidity promptly prevents wood rot, sagging floors, and other structural issues. 
  • Avoid Health Risks: Humidity over 60% enables mold colonies to grow, damaging wood and releasing spores. A dry crawl space prevents mold growth, safeguarding the health of the inhabitants. 
  • Deter Pests: Termites, carpenter ants, and rodents are attracted to moist crawl spaces. Proper crawl space encapsulation and dehumidification create a less hospitable environment for pests. 
  • Reduce Allergens: Mold spores and dust mites aggravate respiratory problems like asthma. 
  • Improve Air Quality: Stop musty odors and contaminated air from entering your home. 
  • Save on Energy Bills: Lower humidity relieves pressure from your HVAC system. Proper insulation and humidity control lead to more efficient energy usage and lower bills. 
  • Maintain Property Value: A well-maintained crawl space enhances the overall value of your property.
