Job Stories From Addison, PA
Fixing a Wet Basement

Recently, we had the opportunity to help a homeowner in Addison, PA, breathe new life into their basement. For years, they were battling a wet basement issue that had become more trouble than it was worth. They grew tired of the constant clean-ups and concerns about potential damage. That's when they reached out to us here at Keystone Basement Systems. With an eagerness to solve their problem, our Customer Care team quickly scheduled an inspection of their home. Our System Design Specialist, armed with years of experience, conducted a comprehensive review of the situation. It quickly became clear that the solution to their problem was WaterGuard, our reliable basement waterproofing system. Installing WaterGuard isn't just about putting a product in the ground. It starts with preparing the perimeter of the basement; trenching boils down to creating a space where WaterGuard can be most effective in capturing wall and floor seam water leakage. Once the groundwork was laid out, our diligent installation team got to work, ensuring each piece was positioned for optimal water routing. After a careful installation coupled with keen attention to maintaining a clean workspace, WaterGuard seamlessly camouflaged with their basement surroundings. The outcome was everything the homeowner hoped for – a dry basement with the freedom to use the space without worry. Wet, dingy basements can now be a thing of the past. By choosing Keystone Basement Systems, this homeowner now enjoys peace of mind, knowing their basement issues have been permanently fixed. The persistence of wet basements can disrupt any home, but with our dedicated team and WaterGuard, solving this annoyance has never been simpler.
