This page guides you through wet crawl space problems, how to fix them for good, and why our full encapsulation system is the ideal solution.  

What is Wet Crawl Space Insulation? 

Wet crawl space insulation refers to the damp, saturated fiberglass batts you’ll often find drooping from floor joists. This kind of insulation quickly becomes useless when moisture seeps into a vented crawl space, unable to provide proper insulation and heat retention. Peeling back the insulation reveals blackened wooden beams dripping with condensation, a major red flag. 

Beyond losing R-value quickly, wet insulation can lead to various problems, including: 

It’s clear that fiberglass batt insulation does not hold up well over time in damp crawl spaces. The perpetual moisture causes problems to spiral, which is why a full encapsulation system is the best permanent solution. 

What Causes Wet Crawl Space Insulation? 

There are several reasons why you may be dealing with chronically wet insulation in your crawl space: 

  • Vented Crawl Spaces: Most crawl spaces have open vents. This allows outdoor air to circulate in the space, introducing moisture that condenses on cool surfaces. Fiberglass insulation readily absorbs this moisture. 
  • Cool Temperatures: Our winters drop to freezing temperatures, causing condensation to form in the cooler crawl space air. 
  • High Humidity: While our climate is generally dry, rain through spring and fall can drive up humidity. Damp soil in the crawl space contributes as well. 
  • Plumbing Leaks: Leaking pipes, HVAC equipment, or appliances in the crawl space contribute extra moisture. 
  • Flooding: Situational flooding from rain or snowmelt can quickly saturate a crawl space. 
  • Poor Drainage: Insufficient drainage allows water to pool in the crawl space during wet months. 

Once moisture gets into the crawl space, traditional fiberglass quickly becomes useless for insulation. The real solution is a sealed, encapsulated crawl space. 

Can You Fix Wet Crawl Space Insulation? 

Yes, wet insulation in your crawl space can and should be fixed. However, simply replacing the insulation treats a symptom, not the underlying moisture problem. 

To properly address wet crawl space insulation, you need a comprehensive solution to control moisture and completely seal the space. Foundation Repair of Western Colorado offers full crawl space encapsulation, the most effective method.

Why Address Wet Crawl Space Insulation Issues Now 

Fixing wet crawl space insulation creates many benefits for your home and family, including: 

  • Prevent Mold Growth: Wet conditions foster mold growth, which spreads spores and musty odors throughout your home. Encapsulation eliminates the excess moisture mold needs to thrive. 
  • Improve Air Quality: Removing dampness improves indoor air quality by limiting opportunity for mold growth and associated allergens/irritants. 
  • Enhance Energy Efficiency: Conditioning the space allows HVAC systems to work more efficiently. Insulated walls increase heat retention significantly. 
  • Reduce Pest Infestations: Bugs and rodents are attracted to moist wood and insulation. Sealing the space makes pest entry difficult and creates a less attractive environment for them. 
  • Stop Wood Rot: Wet conditions rot wooden structures like floor joists and subfloors. Controlling moisture prevents further expensive damage. 
  • Protect Health: Stop worrying about what airborne mold and pests could be aggravating allergies or illness. Breathe easier in your home after encapsulating the crawl space. 

Don’t live another day with a wet, unhealthy crawl space. Encapsulation by Foundation Repair of Western Colorado brings mold relief and energy savings with one call.
