If your crawl space isn’t sealed, your HVAC system is working overtime to heat and cool leaking air. Encapsulation reduces air leaks and improves efficiency, helping your system run smoothly. Studies show homeowners save up to 15% on heating and cooling costs after encapsulation! You can increase these savings by insulating your attic at the same time.
Healthier Indoor Air
Your crawl space directly impacts the air you breathe. By sealing off the source, encapsulation blocks mold spores, allergens, and pollutants like unhealthy wildfire smoke from entering your living spaces. Families in Longmont and Boulder County notice cleaner, fresher air, which is especially important for anyone with asthma or allergies.
Protect Your Home‘s Value
Moisture is the enemy of your home’s foundation. Encapsulation prevents rot, pests, and costly structural damage, extending the life of your property. Not only does this safeguard your investment, but it also increases property value.
Our Crawl Space Encapsulation Process
Inspection & Preparation
Every project begins with a thorough crawl space evaluation or energy audit. Our team inspects for moisture, mold, or pest issues that could compromise your home’s air quality or structure. This ensures we create the right plan for long-lasting protection.
Installation
After preparation, we carefully install the materials needed to seal and protect your crawl space. Each step is designed to stop energy loss, control moisture, and improve indoor comfort.
- Vapor barrier placed across the ground and walls
- Air sealing with spray foam to stop leaks
- High-performance insulation options such as rigid foam, closed-cell spray foam, or vinyl-wrapped fiberglass
- Sump pump or dehumidifier added if needed for maximum moisture control
Together, these solutions ensure your crawl space is completely sealed and built to perform efficiently in Colorado’s changing climate.
Final Sealing
To complete the job, we encapsulate rim joists and critical seams to form a continuous air barrier. This step locks in efficiency and prevents future leaks. The result is a durable, efficient, and healthier crawl space.
