From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Glenmont 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 Glenmont 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 Glenmont 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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Glenmont customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.

Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Glenmont crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in Glenmont happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
