Basement Waterproofing Success in Arlington, VA

When a homeowner in Arlington, VA, discovered water damage and warping baseboards in their basement, they knew it was time to take action. The visible signs of moisture intrusion had compromised the space, raising concerns about long-term structural and health risks. To address these serious issues, they turned to us for a professional basement waterproofing solution they could rely on. After a thorough inspection of the basement, we developed an integrated waterproofing plan tailored to their needs. The solution included the installation of our WaterGuard system, a state-of-the-art perimeter drainage channel designed to divert water away from vulnerable areas. To further protect the basement, we installed the TripleSafe Sump Pump, which provides triple layers of defense against water intrusion, even during power outages. To seal and protect the walls, we utilized our durable CleanSpace liner, which acts as a moisture barrier while brightening the basement’s appearance. Finally, IceGuard was strategically added to safeguard the system against freezing conditions, ensuring year-round functionality. The transformation speaks for itself. The "before" state showed undeniable water damage, but the "after" results highlight a dry, healthy, and usable basement space. This project demonstrates our expertise in basement waterproofing and our dedication to delivering durable solutions. For homeowners in Arlington, VA, and beyond, we stand ready to solve water intrusion problems with precision, quality, and proven systems like WaterGuard, TripleSafe, CleanSpace, and IceGuard.
