As a homeowner, maintaining a healthy indoor environment is crucial. One common issue many encounter is high indoor humidity, which can stem from various causes and lead to several problems if not addressed properly. This comprehensive guide will help you understand the reasons behind your high indoor humidity and provide actionable steps on how to rectify it.  

What Causes High Indoor Humidity?

Condensation in the crawl space

High indoor humidity often originates from your crawl space. Here are some potential sources: 

Opened Crawl Space Vents

 Open crawl space vents were once considered a necessary feature to reduce moisture. However, these vents often increase humidity, as the meeting of cool and warm air can lead to condensation and increased relative humidity. 

Dirt Crawl Space

While more cost-effective and easier to install, dirt crawl spaces often contribute to high humidity. The moist earth underneath can cause significant humidity problems unless you install a durable water vapor barrier. 

Rain and Flooding

 Heavy rainfall and flooding can increase hydrostatic pressure on your home’s foundation, leading to additional moisture in your crawl space. Flooding, particularly in areas with distinct wet and dry seasons, can also contribute to this problem. 

Why Should I Fix My High Indoor Humidity?

 Ignoring high indoor humidity can have several undesired outcomes, emphasizing the importance of finding a solution. 

  •  The Stack Effect: Poor crawl space encapsulation can lead to the stack effect, where air enters from the bottom and exits from the top, carrying moisture, mold spores, and other airborne contaminants.
  • Mold Growth: Mold, which can thrive in relative humidity as low as 60%, is a significant concern associated with high indoor humidity. 
  • Wood Rot: High humidity can also cause wood rot, a type of fungus that rapidly spreads and can compromise your home’s structural integrity. 
  • Increased Electric Bills: High indoor humidity can make your home feel warmer and put more strain on your air conditioning, increasing energy consumption by 15-25%. 

How Can I Fix High Indoor Humidity?

1. Remove Standing Water

  •  The initial step involves removing any standing water in the crawl space, which continually contributes to humidity. 
  • Consider using an interior drainage system and a sump pump, and consult a crawl space repair expert for the best solution. 

2. Permanently Seal Crawl Space Vents 

  •  Contrary to popular belief, crawl space vents often increase humidity. Closing these vents can help control moisture. 
  • JES offers crawl space vent covers for this purpose. 

3. Install Vapor Barrier System 

  • Vapor barrier systems are essential in preventing moisture from rising from your dirt crawl space. 
  • JES recommends the CrawlSeal™ 20-mil crawl space vapor barrier, exceeding the thickness required by most residential codes. 

4. Add a Dehumidifier 

  • Following encapsulation of your crawl space, a dehumidifier can be beneficial in maintaining stable and healthy humidity levels. 
  • Do note that dehumidifiers alone won’t fix the problem unless other mentioned steps are also taken. 

By understanding these causes and solutions, you’ll be well-equipped to lower humidity in your house, ensuring a healthier and more comfortable living environment. Always consult with a professional like JES for personalized solutions for your specific needs.
