Recently, a homeowner in Washington, DC noticed a chilling problem – the lower level of their house was significantly colder than the upper level, turning their basement and crawl space areas into uncomfortable cold spots. Understandably concerned about the energy efficiency and livability of their home, they reached out to us at NV Waterproofing & Foundation Repair for a solution. After the homeowner made the initial contact, our Customer Care team quickly scheduled a thorough home inspection.

Recently, we tackled a unique crawlspace renovation project in Washington, DC, involving a shared space among four homeowners—a true example of urban living challenges. This shared crawlspace had a series of pressing issues, including a small, restrictive opening that hindered access and ventilation, structural beams in need of reinforcement, and a lack of proper encapsulation and insulation to combat moisture intrusion.

Our approach began with a detailed inspection by one of our seasoned System Design Specialists, who evaluated the complexities of this communal space. To address the issues, they proposed a comprehensive solution tailored to the crawlspace's needs. First, we enlarged the crawlspace opening, significantly improving access for future maintenance and ventilation. Next, to stabilize the beams and enhance the structural integrity of all four homes, we installed SmartJacks—our reliable foundation support system. Finally, we encapsulated the crawlspace using our durable CleanSpace system, creating a seamless moisture barrier. This was paired with SilverGlo insulation, which not only added to the moisture protection but also enhanced energy efficiency for all homeowners.

The results were transformative. This shared crawlspace is now a dry, stable, and energy-efficient space that safeguards the homes above. By combining SmartJacks, CleanSpace encapsulation, and SilverGlo insulation, we delivered a long-lasting solution that highlights our expertise in crawlspace renovations in Washington, DC.
