Halo Water Proofing has been the Nanjemoy area's go-to call for Waterproofing because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing started as a small MD crew and grew because Nanjemoy customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Nanjemoy job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.

Odor is often the first sign Nanjemoy customers notice, well before any visible water shows up.
Hairline cracks can widen over a Nanjemoy winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Nanjemoy call we prioritize fast.

Standing water in your basement doesn't wait for business hours, and neither do we. Our Nanjemoy emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
