Basement Waterproofing & Leak Repair in Alexandria

If you have leaky cracks in your basement walls or floor, or you have a basement that floods, we have a solution. Our trained technicians provide you with a comprehensive analysis of what's causing your basement water problem, and the proper solution to solve it once and for all.

We only install products that we know work, this includes:

  • Multi-pump, cast-iron, submersible sump pump systems with built-in high water level alarm
  • Battery backup pumps for continuous operation and protection in power outages

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.

We have recently been dealing with mice in the house. Orkin Pest Control inspected the crawlspace, found a nest, and gave us a quote for sealing openings, cleaning up what's already there, and possibly adding a barrier. I'm looking for other estimates and opinions.

We got our crawlspace waterproofed/vapor barrier, remediated from mold, etc. and it looks great. It was recommended by our inspector to have someone come back a few months after things have settled to see if there is any foundational/structural issues, or minor repairs, that might be needed now that things are in a better, steady state. We'd love for you to come back and see if any work there is needed. Thank you.
