Job Stories From Alexandria, VA
Basement Peace of Mind in Alexandria, VA

This Alexandria, VA homeowner had plans to finish his basement. Unfortunately, those plans were delayed due to continued water intrusion in the basement. We proposed the installation of our WaterGuard sub-floor drainage system, a 1/3 hp TripleSafe sump pump, a new exterior drainage line complete with IceGuard to prevent clogging, and CleanSpace vapor barrier to permanently fix his water issues. This prevents further damage and allows for peace of mind to finally finish the basement to make it an enjoyable space.

In heavy rain, the drain outside my back basement door gets overwhelmed/backs up and the standing water then pours into my basement quickly. I have a sump pump in my basement but am not sure it is operational. Wondering if adding an outside pump might resolve flooding issues.
