Basement Waterproofing Before & After Photos

What was once a damp, cluttered space in an Arlington, VA basement has now been completely transformed into a dry, neat, and reliable part of the home. The homeowner had been dealing with persistent moisture issues, so they turned to NV Waterproofing and Foundation Repair for a long-term solution—one that didn’t just mask the symptoms but addressed the root of the problem.

We installed our WaterGuard® interior drainage system along the perimeter to effectively capture and redirect incoming water before it could reach the floor. To further protect the space, our team applied the CleanSpace® vapor barrier, sealing the walls against moisture and creating a brighter, cleaner environment. We also installed the powerful SuperSump® system to ensure consistent water removal, even during heavy storms.

But we didn’t stop there—we completed targeted exterior drainage improvements to reinforce protection and make certain water stays out for good.

Today, that Arlington basement isn’t just cleaner—it’s confidently protected. At NV Waterproofing and Foundation Repair, we believe peace of mind begins from the ground up.

A homeowner in Winchester, VA, was struggling with a failing sump pump that couldn’t keep up during heavy rainstorms, leaving their basement vulnerable to water intrusion. The lack of a reliable backup system also left them worried about potential flooding during power outages. Frustrated and seeking a dependable solution, they contacted NV Waterproofing and Foundation Repair, a trusted basement waterproofing company in Winchester, VA.

After assessing the situation, we replaced their old sump pump with a state-of-the-art TripleSafe Sump Pump system. This advanced system includes three levels of protection: a primary pump, a secondary pump for heavy water flow, and a battery backup to ensure the basement stays dry even during power outages. The homeowner now has peace of mind knowing their basement is fully protected, no matter the weather.

A homeowner in Warrenton, VA, was dealing with a frustrating issue—water intrusion in their basement. Cracks along the foundation walls were allowing water to seep in, creating a damp and unusable space. Concerned about the long-term damage to their home, they reached out to NV Waterproofing & Foundation Repair for help.

Our team quickly got to work, addressing both the root cause and the symptoms. To stabilize the home, we repaired the foundation settlement by installing piers, ensuring the structure was secure. Next, we installed a WaterGuard® system to effectively channel water away from the basement. Finally, we added a TripleSafe™ Sump Pump for reliable, long-term water protection.

In Catlett, VA, a homeowner was dealing with a persistent and potentially damaging issue—water intrusion in the basement. Every time it rained, water would seep into the space, creating damp conditions and raising serious concerns about mold growth, structural damage, and indoor air quality. The before photo clearly shows signs of moisture and the beginnings of what could become long-term basement problems if left untreated.

When the homeowner reached out to NV Waterproofing & Foundation Repair, our expert team promptly scheduled an inspection and developed a customized waterproofing plan to permanently resolve the issue. Our goal was to turn the damp, vulnerable basement into a dry, healthy, and usable part of the home.

To accomplish this, our crew installed a full interior waterproofing system starting with the WaterGuard® drainage system, which discreetly captures water seepage at the base of the walls and under the floor. From there, water is funneled directly into the SuperSump® system, a powerful and reliable sump pump designed to keep basements dry under even the harshest weather conditions. For added protection during winter months, we installed IceGuard®, a discharge line system that prevents water from backing up if the pipes freeze.

In addition, we applied the CleanSpace® vapor barrier along the interior basement walls. This heavy-duty liner acts as a moisture and mold barrier, dramatically improving the overall air quality while giving the basement a clean, finished appearance.

To further protect the entry point of the basement, where surface water was entering near the door, we installed a trench drain. This feature helps capture and redirect rainwater before it has a chance to enter the basement—an essential defense in properties with exterior basement doors or sloped landscapes.

As shown in the after photo, the transformation is striking. The basement is now completely dry, well-protected, and safe for storage or future finishing. Thanks to NV Waterproofing’s professional team and proven waterproofing systems, this Catlett, VA homeowner can enjoy peace of mind knowing their basement is secure for years to come.

In the heart of Leesburg, VA, a historic home was facing a quiet but persistent enemy—basement moisture. Beneath its timeless charm and original craftsmanship, damp walls and pooling water threatened to undermine both the structure and the legacy of the property. The homeowner, deeply committed to preserving the soul of the space, turned to NV Waterproofing and Foundation Repair to bridge the gap between old-world beauty and modern protection.

Our approach blended care with cutting-edge solutions. After a detailed assessment, we installed a full waterproofing system designed to work in harmony with the home's historic foundation. CleanSpace was applied to shield the basement walls with a durable, moisture-blocking barrier. Beneath the surface, WaterGuard captured intruding groundwater, channeling it to the powerful SuperSump system for fast, reliable removal. And to protect the system year-round—even during harsh Leesburg winters—we added IceGuard, ensuring water can escape even when temperatures dip below freezing.

The transformation was profound. What was once a damp, aging basement is now dry, clean, and ready to support modern living—all without compromising the integrity of the home’s history.

At NV Waterproofing and Foundation Repair, we don’t just fix old homes—we help them thrive. In Leesburg and beyond, we’re redefining what it means to protect the past while building for the future.
