Halo Water Proofing has been the Annapolis area's go-to call for Sump Pump Installation 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 Annapolis customers kept referring us to neighbors β that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Annapolis 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.
π +1-866-476-1348Most Annapolis 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 Annapolis customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Annapolis-area homes.
Efflorescence is a clear sign that water is actively passing through your Annapolis foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time β usually during the next big Annapolis storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Annapolis 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 Annapolis emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service βFreeze-thaw cycles in Annapolis, MD push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment βMost sump pump failures we see in Annapolis happen during the exact storms that need them most β a battery backup closes that gap when the power drops.
Schedule a Pump Inspection βSome Annapolis lots need both an interior and exterior system working together β we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems βOlder Annapolis homes with vented crawl spaces are especially prone to seasonal moisture swings β encapsulation closes that off for good.
