Licensed & insured in MD ยท 24/7 dispatch

Halo Water Proofing is a MD-licensed Foundation Crack Repair company that treats every Greenbelt job like it's the only one on the schedule.
We don't run a bidding war between crews. The Greenbelt technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Greenbelt homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Greenbelt technician today, not an automated queue. We'll explain what's going on and get you scheduled.
๐ +1-866-476-1348Most Greenbelt calls didn't start with a flood โ they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Greenbelt basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue โ this jumps to the front of our Greenbelt schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Greenbelt basements are the same โ soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Greenbelt emergency line busy โ active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help โWe seal active Greenbelt foundation cracks with epoxy injection โ stopping the leak at its source instead of patching the surface.
Ask About Crack Repair โAlready have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check โAn interior drain tile system routes water to a sump pump before it reaches your Greenbelt basement floor at all.
Talk Drainage Options โMusty smell upstairs with no obvious source? Check the crawl space first โ it's usually the culprit.
Get a Crawl Space Quote โWe can phase larger Greenbelt commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote โNo pressure, no scripts โ just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure โ just a clear look at what's actually going on.
The number you approve is the number you're billed โ no change orders once the crew shows up.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
