Crawl Space Insulation Replacement and Installation

A drafty home and rising energy bills are more than just everyday annoyances—they’re issues you don’t have to tolerate. These issues typically indicate excessive moisture, with inadequate crawl space insulation being the primary culprit.

Insulation for crawl space areas is crucial for a comfortable and healthy indoor environment. Without it, your home risks mold growth and structural damage.

As home health experts in Virginia, Washington, D.C., Maryland, North Carolina, and West Virginia, our crawl space encapsulation solutions resolve and prevent problems, including wet crawl space insulation.

This page outlines what you need to know about crawl space insulation and how JES Foundation Repair can help.

What is Crawl Space Insulation?

Crawl space insulation is a barrier material installed beneath your home to regulate indoor flooring temperatures and reduce moisture. Adequate insulation for crawl spaces provides a barrier against heat loss, reduces moisture and mold growth, and provides many other benefits.

We considered these factors when developing ExTremeBloc. Designed to endure wet crawl space insulation conditions, these panels perform optimally when combined with our comprehensive encapsulation solutions. These systems seal the crawl space and provide a healthier home environment by effectively insulating a crawl space.

Signs You Need Better Crawl Space Insulation

Recognizing the signs of crawl space insulation failure is essential. However, entering the crawl space can be hazardous, so leaving this task to professionals with the proper safety gear and tools is best. Here are the signs you can watch for as a homeowner and the areas our inspectors examine in your crawl space:

Excessive crawl space moisture can lead to significant issues and costly repairs. When you notice the problem signs, schedule a free inspection with a crawl space professional like JES Foundation Repair. 

Is Crawl Space Insulation Necessary? 

Crawl space insulation is crucial to home health, safety, and comfort. We do not recommend insulating crawl space areas alone, as big-box store products often fail to address the underlying problems. Professionals ensure thorough crawl space assessment, thorough repair, and long-lasting protection. 

Common Types of Crawl Space Insulation 

Crawl space insulation comes in various forms, with three common types used throughout Virginia, Maryland, Washington, D.C., Northeast North Carolina, and West Virginia:

damaged crawl space fiberglass insulation
  • Fiberglass: Common in homes nationwide, fiberglass is not ideal for crawl spaces. Typically installed between floor joists, this soft material is vulnerable to moisture, mold, and pests.
  • Spray Foam: Often applied to walls and joists, spray foam isn’t the best choice for crawl spaces. While closed-cell types are durable, they can still be affected by mold, chemical odors, and termite damage in damp areas.
  • Foam Board: Thermal foam board insulation, like ExTremeBloc, is ideal for crawl spaces. Custom-fit panels are installed on interior walls with reflective surfaces to retain heat. Although thinner than fiberglass, ExTremeBloc provides superior insulation value.

What Are the Benefits of Crawl Space Insulation? 

Homeowners gain several benefits when insulating a crawl space, including: 

encapsulated crawl space
  • Moisture control
  • Mold prevention
  • Fewer pest infestations
  • Long-term energy savings
  • Consistent indoor floor temperatures
  • Enhanced indoor air quality
