Crawl Space Humidity

While Colorado has a typically dry climate, crawl space humidity is still a challenge in many homes, causing various issues from structural damage to health risks. 

Effectively managing humidity levels improves the state of your crawl space and ensures a safer, healthier living space for you and your family. 

With more than 15 years of experience, Foundation Repair of Western Colorado specializes in assisting homeowners with this prevalent problem. Our skilled team performs thorough inspections to pinpoint the root causes of humidity and delivers custom crawl space encapsulation solutions for effective resolution. 

This page provides insights into the causes and impacts of crawl space humidity and explains how professional intervention can offer lasting solutions. 

What Is Crawl Space Humidity? 

Crawl space humidity refers to excessive moisture in the air and surfaces within the crawl space beneath your home. This space, situated between the ground and first floor, is inclined to turning damp because of its nearness to the soil. 

When relative humidity levels top 60%, various problems can develop, including: 

Addressing humidity is crucial for your home’s structural integrity, air quality, and your family’s health and comfort. It’s important to contact a crawl space expert like Foundation Repair of Western Colorado as soon as you notice any of these issues. 

What Causes Crawl Space Humidity? 

There are several sources of crawl space humidity, including: 

  • Open Vents: Open crawl space vents allow outdoor air to enter the crawl space while failing to adequately ventilate the space, trapping moisture inside. 
  • Cool Crawl Space Temperatures: Naturally cooler crawl space surfaces lead to condensation. 
  • Plumbing Leaks: Leaking pipes or appliances increase moisture. 
  • Water Intrusion: Rain or snowmelt can lead to puddles if drainage is poor. 
  • High Water Table: A high groundwater level introduces moisture into the crawl space. 
  • Sump Pump Issues: An open or faulty sump pump allows water and humidity to escape into the crawl space. 
  • Poor Landscape Grading: Improperly graded soil or excessive watering directs moisture into the crawl space. 

Careful inspection by a crawl space specialist helps identify factors unique to your home contributing to unwanted humidity. 

Can You Fix Crawl Space Humidity? 

Yes, excessive crawl space humidity can be fixed through professional crawl space encapsulation. DIY projects like adding a vapor barrier or sealing vents may provide temporary relief but fail to address underlying causes. 

To effectively control humidity, the whole crawl space environment must be considered. Foundation Repair of Western Colorado offers complete encapsulation systems designed specifically to create an ideal, conditioned crawl space environment. 

By controlling moisture at its sources, removing excess water, and regulating the climate, our crawl space systems create a dry, conditioned space. This prevents humidity-related damage and maintains indoor air quality.

Why Address Crawl Space Humidity Now? 

Promptly addressing crawl space humidity creates numerous benefits for your home and family, including: 

  • Preventing Structural Damage: Moisture can lead to the deterioration of wooden structures, undermining the integrity of floors, beams, and overall stability. Timely action against humidity can prevent wood rot, sagging floors, and other structural complications. 
  • Avoiding Health Risks: High humidity levels, particularly above 60%, foster mold growth, which damages wood and releases harmful spores. Keeping the crawl space dry helps prevent mold growth and spread, protecting the health of those in the home. 
  • Discouraging Pests: Moist environments in crawl spaces attract termites, carpenter ants, and rodents. Effective encapsulation and dehumidification of the crawl space make the area less inviting. 
  • Reducing Allergens: Mold spores and dust mites, common in damp environments, can exacerbate respiratory issues such as asthma. 
  • Improving Air Quality: Eliminate musty odors and prevent contaminated air from infiltrating your living spaces. 
  • Saving on Energy Bills: A less humid environment reduces the strain on your HVAC system. Proper crawl space insulation and humidity control contribute to more efficient energy usage, leading to lower energy costs. 
  • Maintaining Property Value: A well-maintained crawl space is a key factor in preserving and enhancing your property’s value.
