Halo Water Proofing has been the Glenn Dale area's go-to call for Waterproofing because we answer the phone, show up on time, and stand behind the work.
We're Halo Water Proofing — a MD-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Glenn Dale-area foundations, and exactly how to stop it.

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.
📞 +1-866-476-1348Most Glenn Dale customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Glenn Dale winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Glenn Dale foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Glenn Dale lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Glenn Dale call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Glenn Dale crews trace back to a drainage issue.
Every Glenn Dale property is different — 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 Glenn Dale emergency crews remove the water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Glenn Dale, 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 →Already have a sump pump that's failing or too small for your Glenn Dale lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Glenn Dale basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Glenn Dale crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Glenn Dale commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Glenn Dale crews follow on every job.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
