From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Annapolis 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 Annapolis customers kept referring us to neighbors β that's still how most of our work comes in today.

Every technician on our Annapolis 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.
One call gets you a straight answer and a real appointment window β not a call-back promise.
π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our Annapolis technicians hear about most often before an inspection.
Odor is often the first sign Annapolis customers notice, well before any visible water shows up.
Even small cracks are worth a second look β they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence β mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Annapolis lot's water table.
This is one sign we tell Annapolis customers not to wait on β wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Annapolis homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Annapolis every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Annapolis emergency crews remove the water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service βA cracked foundation wall isn't just a cosmetic issue β it's a water entry point and, over time, a structural one. Our Annapolis crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment βAlready have a sump pump that's failing or too small for your Annapolis lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume β not the cheapest unit on the truck.
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.
Get a Crawl Space Quote βWe can phase larger Annapolis commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

We start with a phone conversation, not a script β enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Annapolis property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Annapolis job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Our trucks stage locally around Annapolis, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Our repairs come with written, transferable warranties β a real asset if you sell the Annapolis property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Word of mouth is still how most Annapolis customers find us, which keeps our standards higher than a big out-of-town franchise.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
