From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Centreville before. We show up, we diagnose it straight, and we fix it right.

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

Every technician on our Centreville crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone β no upsell surprises when the truck pulls up.
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.
π +1-866-476-1348Most Centreville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Centreville customers notice, well before any visible water shows up.

Every Centreville property is different β soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Centreville emergency crews pump out the basement first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service βHairline cracks are how most Centreville basements start leaking. We use epoxy injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment βMost sump pump failures we see in Centreville happen during the exact storms that need them most β a battery backup closes that gap when the power drops.
Schedule a Pump Inspection βAn interior drain tile system channels water to a sump pump before it ever reaches your Centreville basement floor β one of the most reliable long-term fixes we install.
