Professional Foundation & Concrete Repair in McLean, VA

A homeowner in McLean, VA reached out after dealing with a persistent wet basement in Fairfax, VA, especially during heavy rainstorms. Water was seeping through the foundation walls and collecting along the perimeter, creating a damp, musty environment and raising concerns about long-term damage. Like many homes in McLean and throughout Fairfax County, poor drainage and hydrostatic pressure were the primary causes. The homeowner scheduled a free inspection with a trusted basement waterproofing contractor to properly diagnose the issue and find a lasting solution.

After a thorough evaluation, we recommended a full basement waterproofing system designed to capture and redirect water before it could enter the living space. Our team installed a WaterGuard® interior drainage system along the perimeter, paired with a high-performance sump pump to efficiently remove water from the home. We also added IceGuard® to prevent discharge line freezing during winter months and extended the drainage line to a LawnScape™ outlet to ensure water is carried safely away from the foundation. To complete the system, we applied CleanSpace® to the basement walls, creating a clean, sealed barrier that helps protect against moisture and improves the overall environment.

The results were immediate and long-lasting. The basement is now dry, healthy, and fully protected—even during heavy storms. The homeowner no longer has to worry about water intrusion or ongoing moisture issues. This project highlights how working with an experienced basement waterproofing contractor can provide a permanent solution for homeowners dealing with a wet basement in Fairfax, VA and surrounding areas.

In McLean, VA, a homeowner faced a familiar yet frustrating issue—an uneven pool deck caused by sinking concrete slabs. With summer gatherings just around the corner, ensuring a safe and visually appealing outdoor space became a top priority. Uneven surfaces posed tripping hazards and compromised the enjoyment of the area, prompting the homeowner to reach out to NV Waterproofing and Foundation Repair for a fast, effective solution.

After speaking with our dedicated Customer Care Specialist, a prompt inspection was scheduled. Our experienced System Design Specialist arrived to assess the situation and identified the perfect fix: PolyLevel concrete lifting to raise the sunken slabs and NexusPro joint sealant to protect the area from further damage. These advanced systems are engineered to provide long-lasting results with minimal disruption.

Our skilled production crew arrived on time, fully prepared to restore the pool deck. Using precision drilling, small pea-sized holes were made in the affected slabs, allowing us to inject PolyLevel, a high-density polyurethane foam, beneath the surface. This innovative method gently lifted and leveled the slabs with impressive accuracy, bringing the deck back to its original, even position. To complete the transformation, we applied NexusPro, a durable, flexible sealant designed to seal joints and cracks, providing superior resistance to moisture, UV rays, and seasonal temperature changes.

The result? A fully restored, safe, and aesthetically pleasing pool deck—ready for countless worry-free summer gatherings. The homeowner was thrilled with the clean workmanship, quick turnaround, and noticeable improvement in both appearance and safety. At NV Waterproofing and Foundation Repair, we pride ourselves on delivering durable, innovative solutions that enhance your home’s value and your peace of mind.

Last month, a homeowner from McLean, VA, reached out to us at NV Waterproofing and Foundation Repair with a rather common issue they were facing - the need for a reliable solution to manage excessive moisture in their crawlspace and basement. Understanding the importance of a safe and dry home, they were particularly interested in installing a dehumidifier. After contacting our customer care team, we followed our standard procedure starting with an in-depth home inspection. Our System Design Specialist visited the home, conducted a thorough inspection of the crawlspace, and the basement, to determine the most appropriate solution. Given the scenario, we recommended installing a SaniDry Sedona - a high-efficiency dehumidifying system known for its exceptional capability to maintain an optimal humidity level, ensuring the air in basements and crawlspaces stays dry and healthy. Upon agreement, our dedicated production team, led by our expert foreman, set to work. The installation of the SaniDry Sedona is a journey that goes beyond merely placing the unit within the premises. We ensured its correct positioning for maximum effectiveness, calibrated it to suit the specific requirements of their space, and walked the homeowner through its operations for ease of use. The outcome spoke volumes. Not long after the installation was complete, the homeowner noticed a significant improvement in the air quality – it was noticeably fresher and free from that damp feeling that once permeated their home. Thanks to the SaniDry Sedona, the risk of mold and mildew growth diminished dramatically, reestablishing their basement and crawlspace as clean, dry areas of their home. For us at NV Waterproofing and Foundation Repair, it was another day's job well done,

This homeowner was ready to put their home on the market. Then, they were told it would be difficult to sell if the basement had active water seepage. After having our WaterGuard system installed, they were able to sell their home for what it's worth.

A McLean homeowner had an interior system installed to cover the entire front wall of the basement. The one thing he didn't want to see visible, was the sump pump discharge line. By hiding them under the concrete slab, we made that possible for this homeowner.
