Crawl Space Insulation Replacement & Installation

Is your home feeling drafty, and are your energy bills higher than usual? These are more than just everyday nuisances; they may indicate moisture issues in your crawl space caused by ineffective insulation.

Proper crawl space insulation is crucial for a comfortable, healthy home. Without it, your living space is at risk of mold growth, pest infestations, and structural damage. Insulating this area is a preventive step that boosts your home’s energy efficiency.

Mount Valley Foundation Services provides trusted crawl space solutions in Columbia, Charleston, and Savannah to enhance your home’s comfort. We specialize in crawl space encapsulation to resolve existing moisture problems and prevent future issues.

Crawl space insulation is a specialized material installed in the area underneath your home to regulate internal temperatures and prevent moisture-related issues.

Crawl space insulation creates a barrier that minimizes heat loss, reduces moisture and mold, deters pests, and enhances energy efficiency.

At Mount Valley Foundation Services, we consider these benefits when recommending insulation solutions. Our preferred product, ExTremeBloc™, withstands damp crawl space conditions. When used as part of our comprehensive encapsulation strategy, these crawl space insulation panels control moisture and humidity, reduce energy costs, and improve indoor air quality.

• Sagging or bouncy floors 
• Cold floors in winter 
• Rising energy bills 
• Musty smells 
• Allergy or asthma symptoms caused by poor air quality 
• High indoor humidity 

• Fiberglass: Fiberglass is common in homes and is typically installed between floor joists. However, as illustrated in this image, it is not ideal for crawl spaces because it is prone to pest infestation, mold growth, and other moisture issues. 
• Spray Foam: Spray foam, applied to crawl space walls and joists, is often closed-cell, making it more rigid and difficult to remove. However, it is also not the best choice for crawl space areas because it, too, is vulnerable to mold, odors, and termites in damp crawl spaces. 
• Foam Board: Pre-formed thermal foam board sheets, like our exclusive ExTremeBloc™ solution, are more effective for crawl spaces. They offer high insulation value and moisture resistance despite being thinner than fiberglass. 

• Moisture control to prevent dampness and humidity issues
• Mold prevention by regulating moisture levels
• Fewer pest infestations due to the sealed, dry environment
• Long-term energy savings from improved insulation
• Consistent floor temperature for enhanced comfort
