    Challenge: A Damaged and Mold-Infested Crawl Space

    Crawlspace with deteriorated insulation and an exposed gravel floor before encapsulation and mold remediation in Linden, VA.

    The Nielsen family in Centreville, VA, noticed persistent mold growth and musty odors coming from their crawlspace. After contacting several contractors for solutions, they struggled to find a reliable specialist who could address the issue comprehensively. One contractor provided a brief estimate without thoroughly inspecting the crawl space, leaving the family uncertain about the full extent of the problem.

    When LUX Foundation Solutions arrived, our team took a hands-on approach. We conducted a complete crawlspace inspection, entering the space to assess the damaged insulation, the gravel floor, and the open vents that were allowing humidity and air to flow unchecked. During the inspection, we identified clear signs of mold on the floor joists, deteriorating insulation, and odors affecting the home’s air quality.

    Our inspection revealed that the crawl space had never been properly sealed during the home’s construction, allowing moisture from the earth to enter and causing the mold to spread. The lack of proper insulation and humidity control had only worsened the situation over time. To permanently resolve the problem and restore a healthy, dry environment, LUX provided a comprehensive solution that included full encapsulation, removal of damaged insulation, and complete crawlspace mold remediation.

    Solution: Comprehensive Crawl Space Encapsulation and Mold Remediation

    After a thorough assessment, LUX Foundation Solutions developed a plan to address all the issues in the Nielsen family’s crawl space. Our goal was to eliminate the mold, improve air quality, and create a long-term solution to prevent future problems. The following steps were implemented to restore the crawlspace:

    Step 1: Mold and Fungal Treatment

    LUX applied a non-toxic, FDA and EPA-rated cleaning solution to the affected areas of the crawlspace. All visible crawlspace mold and mildew growth were sprayed or fogged, and an inhibitor was applied to prevent future development. Light hand cleaning was performed to ensure thorough coverage.

    Step 2: Insulation Removal and Crawlspace Encapsulation

    LUX removed all damaged insulation between the floor joists and installed a 20-mil Class A fire—and moisture-rated vapor barrier across the crawl space floor. To ensure a fully sealed environment, foundation vents were closed off with rigid foam insulation, and all joints were meticulously sealed for an airtight finish. The columns were wrapped for added moisture protection, and the vapor barrier, backed by an impressive 25-year warranty against rips and tears, provides long-term peace of mind to the Nielsen family.

    Step 3: Insulating Walls and Rim Joist

    To properly insulate the area, rigid foam insulation boards were installed along the foundation walls and between the rim joist. This helps regulate temperature and improve energy efficiency.

    Step 4: Installing Crawl space Drainage Matting

    A high-grade drainage matting was laid across the crawlspace floor to encourage proper drainage. This system helps protect the home from excess moisture and prevents soil erosion under the foundation.

    Step 5: Crawl Space Dehumidifier Installation

    As the final step, the LUX crawl space specialist installed a high-performance crawl space dehumidifier to maintain optimal humidity levels. By controlling the moisture in the air, the dehumidifier prevents mold growth, wood rot, and odors, ensuring the crawlspace remains dry and protected over time.

    Outcome: A Dry and Mold-Free Crawl Space

    The crawl space is now fully encapsulated and insulated, eliminating mold and fungal growth. The newly installed vapor barrier and drainage system provide long-term protection against moisture intrusion. With these improvements, the home is now 20% more energy-efficient, contributing to lower energy bills. 

    Additionally, air quality inside the home has significantly improved, offering a healthier living environment. The high-performance dehumidifier ensures the crawl space remains dry, preventing future mold issues and maintaining the home’s structural integrity.
